Caustic Soda = Volatile Price & Volatile Chemistry.

CAUSTIC SODA = CHEMICAL VOLATILITY AND PROCESS UPSET

Caustic Soda is a HIGHLY CORROSIVE CHEMICAL listed on the Special Health Hazard Substance List. Caustic Soda on contact can burn the skin and the eyes and can cause permanent lung damage through inhalation. Caustic soda in contact with water can create enough heat to ignite combustibles and the resulting fire will produce poisonous gases. THIOGUARD® and THIOGUARD®ΩMEGA-S technical grade magnesium hydroxide is an effective, non-hazardous alternative to Caustic Soda. By converting to THIOGUARD®, wastewater utilities are able to eliminate hundreds of hazardous bulk tanker truck deliveries, thereby reducing insurance costs.

In addition, Caustic Soda freezes at a temperature of 52 degrees, rendering it useless for water treatment purposes, and creating additional hazards by creating increased pressure at valves with the potential unexpected eruptions or spills. When it comes to safety, Thioguard and Thioguard Omega-S technical grade magnesium hydroxide is clearly superior.

CAUSTIC SODA IS A HIGHLY CORROSIVE CHEMICAL…
Caustic Soda is listed on the Special Health Hazard Substance List, and on contact, can burn the skin and the eyes, and can cause permanent lung damage through inhalation. The same properties that can cause these harmful effects in humans are causing similar negative effects in your treatment processes.

Caustic Soda (Sodium Hydroxide) is hazardous to use, detrimental to personnel safety and biological processes. Moreover, adding sodium to wastewater upsets flocculation, settling, clarification and dewatering processes, driving up the need for polymer or metal salt use. All of these potential “Kill Zones” are responsible for driving up costs. The clear solution is to eliminate your “Kill Zones” entirely, by switching to Thioguard.

THIOGUARD and THIOGUARD ΩMEGA-S technical grade magnesium hydroxide is an effective, non-hazardous alternative to Caustic Soda. By converting to Thioguard, wastewater utilities are able to eliminate hundreds of hazardous bulk tanker truck deliveries, thereby reducing insurance costs. When it comes to safety, technical grade magnesium hydroxide is clearly superior.

MORE ALKALINITY PER GALLON

Compared to Caustic Soda (or lime), Thioguard is capable of supplying significantly more alkalinity in a bio-available form to a microbial wastewater system without adversely affecting pH. This creates a more suitable environment for bioremediation of BOD and nutrients like nitrogen and phosphorus. Because magnesium supplies a light-weight, divalent cation, unlike the monovalent sodium in caustic, and heavier calcium in lime, Thioguard generates a denser, more easily dewatered sludge, with a higher percentage of cake solids.

Can Odor Control and Nutrient Treatment and Recovery Co-Exist?

By Thioguard

The Answer is Yes. Choosing Thioguard Mg(OH)2
over Calcium Nitrate will:

(1) Improve Biological Nutrient Removal
(2) Decrease F.O.G. related SSOs and ARV malfunction
(3) Improve pumping and wastewater transfer efficiency
(4) Save money and improve Resource Recovery Across the Board

While Nitrates and Iron have been a common part of the odor control landscape in the past, the growing emphasis on nutrient treatment and resource recovery have made Thioguard technical grade magnesium hydroxide a more compelling and cost effective alternative. Calcium Nitrate products are typically used in many of the nation’s wastewater collection systems, and are used for one thing odor control. Unfortunately, there are multiple costly unintended consequences with the use of nitrate products. In addition, while nitrate use may temporarily address H2S odor problems, nitrate products are of little or no use in combatting corrosion, which is a tremendous problem, both in-plant and throughout every segment of wastewater treatment infrastructure.

NITRATE USE ENCOURAGES
UNWANTED BIOCHEMICAL REACTIONS…

where you don’t want them to occur.

Think denitrification…which consumes organics, and produces nitrogen gas N2 and carbon dioxide CO2, all seemingly innocuous by-products of Calcium Nitrate’s intended use as an odor control technology…but let’s take a closer look…

  1. Nitrates upset the Bio-P process at your plant
    The use of nitrates in the collection system alter the chemical and biological conditions of the collection system, which would otherwise facilitate the formation and transport of VFAs to the treatment plant, where they can be used by PAOs in Bio-P processes.

As VFAs (Volatile Fatty Acids) are eliminated with calcium nitrate addition, VFAs are therefore not available for PAOs (phosphorus accumulating organisms) for phosphate removal at the wastewater treatment plant.

  1. Nitrates contribute to the formation of F.O.G.
    The addition of nitrates contributes to the accumulation of an odorous film, often referred to as a F.O.G. (Fats, Oils and Grease) mat in pumping stations and at your plant. Blockages associated with F.O.G. have been shown to be the greatest contributors to O&M costs including energy consumption, maintenance costs, and Sanitary Sewer Overflows (SSOs).
  2. Nitrates contribute to Gas Binding in the Collection System
    The transfer of wastewater can result in the release of gases such as O2 – Oxygen, CO2 – Carbon Dioxide, N2 – Nitrogen Gas, H2S – Hydrogen Sulfide, CH4 – Methane, VOCs – Volatile Organic Compounds, and VOSCs – Volatile Organic Sulfur Compounds, among others. Some of these gases are drawn into the system through pumping and ventilation, while others are generated within the system either chemically or biologically. These gases can result in the development of gas binding in the system, and are dramatically exacerbated with the utilization of calcium nitrate.
  3. Nitrates negatively impact conventional processes
    The addition of nitrates is not an exact science, and unfortunately, every step along the way there are costly unintended consequences. Add too little, and you’re facing odor problems. Add too much, and you’re faced with the formation of unwanted bubble-forming gases (N2 and CO2 from denitrification) in your settling tank, exactly where you DON’T WANT IT, continuing the formation of F.O.G. mat, (as well as creating an environment unfavorable to your biological processes). This often results in increased metal salts usage or increased polymer usage and associated increases in costs.NITRATE ADDITION REQUIRES MULTIPLE FEED LOCATIONS, THIOGUARD ONLY REQUIRES ONECalcium Nitrate has a short half-life in sewers, and therefore many addition locations are required to achieve adequate system-wide control. This requires several addition locations, and corresponding higher costs and operational oversight. In contrast, a single Thioguard Feed Unit can often replace several nitrate feed stations, and maintain a relatively constant pH level throughout.THIOGUARD HELPS PREVENT CORROSIONMaintaining a constant surface pH of 6-8 can reduce the rate of corrosion by as much as 100X. The cost of simply ignoring this problem is monumental and Thioguard is the only commonly used product that has a direct mechanism to increase surface pH and prevent corrosion.

Treatment Technology Comparison: Iron and Iron Hydrogen Peroxide Treatments vs. Technical Grade Magnesium Hydroxide

By Thioguard

MODERN UTILITY GOALS FOR ODOR AND CORROSION CONTROL, INCLUDE:

  • H2S Prevention and Control
  • Proven Corrosion Control (raise surface pH of corrodible surfaces)
  • Added value for plant BNR processes and solids treatment

Several iron, iron catalyst and peroxide treatments have emerged over the years, and all are designed to treat hydrogen sulfide that has already formed in the collection system. These treatments can be classified as:

  • Iron Sulfate or Iron Chloride treatment
  • Iron Compound added, and wastewater stream later treated with Hydrogen Peroxide
  • Iron Catalyst in combination with Hydrogen Peroxide

The purpose of this document is to illustrate the pitfalls, and hidden costs inherent in depending upon iron and hybrid iron, plus peroxide treatments. What may initially appear to be a cost effective treatment strategy will often result in increased costs and can increase corrosion.

Iron and other hybrid treatments often claim that they prevent corrosion by reducing sulfide gas, but only Thioguard can actually result in increased surface pH on pipes and other infrastructure, in addition to reducing hydrogen sulfide gas. Corrosion is a system-wide problem, requiring a system-wide solution. Thioguard Technical Grade Magnesium Hydroxide treatment is a proven, superior alternative, delivering added value throughout your operation.

The following is a quick comparison of Thioguard to three common classes of treatment:

IRON SALTS/IRON COMPOUNDS TREATMENT

When treating with iron salts, what happens to the alkalinity in the wastewater? One pound of iron salts consumes 1.75 lbs. of alkalinity. Every gallon of iron sulfate, upstream of the plant and in biological processes, can result in significant alkalinity replacement costs later on.

Does iron addition prevent corrosion? No, iron compounds are acidic in nature, and will cause or increase corrosion at your plant. In addition, using iron and proprietary catalysts requires eye wash installations and extensive PPE, one more “hidden cost” of using an outdated technology.

HYDROGEN PEROXIDE TREATMENT – A QUESTIONABLE CHOICE50% hydrogen peroxide treatment depends on oxidizing the hydrogen sulfide, and the reaction is immediate. With this kind of immediate reaction, the result is limited longevity. Treatment must occur immediately before the hydrogen sulfide is released to the atmosphere in a wet well, and therefore may require multiple treatments along an extended line.

In addition, peroxide is extremely dangerous and is generally not considered for use in neighborhoods, medians and right of ways, playgrounds, schools or other sensitive areas. Leaks or tank ruptures can cause fires, property damage and danger to people. In fact, hydrogen peroxide has been used by terrorists as an oxidant for explosives!

HYBRID IRON, CATALYST AND PEROXIDE TREATMENTS –
ANOTHER QUESTIONABLE OPTION

These treatments depend on Iron or a catalyst to achieve hydrogen sulfide complexation, followed by peroxide as a strong oxidant to oxidize the sulfide. Some catalyst treatments warn not to combine their product with hydrogen peroxide – due to the potential for an exothermic reaction. Why introduce this kind of a hazard, when it can be easily avoided?

In general, the iron treatments above do little or nothing to prevent corrosion in long sewer lines, and when used for odor control, they simply cannot compare to the long lasting power of Thioguard to deliver consistent, reliable system-wide performance.

INCREASED ACIDITY = INCREASED CORROSION
INCREASED SURFACE pH = INCREASED STRUCTURAL LONGEVITY

In an acidic environment (pH=2), corrosion is rampant, tearing through 2″ of concrete in as little as 8 years. When effective surface pH=4, similar corrosion levels are pushed out to 50+ years.

Thioguard is the ONLY commonly used product that has a direct mechanism to PREVENT CORROSION by raising surface pH. Moreover, the benefits of adding THIOGUARD to your collection and treatment processes are not limited to the prevention or reduction of corrosion. You will also benefit from a reduction in the formation of sludge – significantly reducing your handling and transportation costs.

COMPARISON TO THIOGUARD CHEMISTRY

In contrast, Thioguard does nothing to lower the pH of the wastewater, produces no reaction products that can lead to additional sulfide production, and produces no sludge to settle out in the system or to be dewatered at the WWTP. The reaction is as follows:

The Magnesium binds the sulfide in a similar manner to iron and it will not be released unless the pH drops to 5.5 which is not normal In wastewater. More importantly, Thioguard is preventative and controls the formation of sulfide by increasing the pH and retarding the Sulfate Reducing Bacteria activity.

CHOOSING THIOGUARD WILL:

  • Decrease Maintenance 
  • Reduce Capital Replacement Costs 
  • Decrease FOG related SSOs and ARV Malfunction

Supplement Alkalinity without the Hidden Operational Costs

By Thioguard

LIME – A CLASSIC “PAY NOW OR PAY LATER” SITUATION

Lime may appear initially to be an affordable way to increase required alkalinity at your plant. However, as with so many other purchase decisions, this “up front bargain” turns into added costs and aggravation down the road. Your plant will NEVER achieve sustained, controlled alkalinity through the addition of lime, or caustic soda for that matter. ONLY THIOGUARD and THIOGUARD ΩMEGA-S technical grade magnesium hydroxide provides an effective, system-wide, non-hazardous alternative to Lime. By converting to Thioguard, wastewater utilities are consistently able to eliminate hundreds of hazardous bulk tanker truck deliveries, thereby reducing insurance costs. And, when it comes to safety, technical grade magnesium hydroxide is 100% non-hazardous.

LIME (Ca(OH)2) IS A HIGHLY CORROSIVE, DANGEROUS CHEMICAL…

Lime is listed on the Special Health Hazard Substance List, and on contact, can burn the skin and the eyes, and can cause permanent lung damage through inhalation. The same properties that can cause these harmful effects in humans will cause similar negative effects in your treatment processes.

Lime (calcium hydroxide) is extremely hazardous to use, detrimental to personnel safety and creates “Kill Zones” in biological processes. Moreover, adding lime to wastewater upsets alkalinity supplementation, by converting soluble forms of alkalinity to insoluble forms. These potential “Kill Zones” are responsible for driving up costs significantly. The clear solution is to eliminate your “Kill Zones” entirely, by switching to Thioguard.

MORE ALKALINITY PER GALLON

Compared to Lime (or caustic soda), Thioguard is capable of supplying significantly more alkalinity in a bio-available form to a microbial wastewater system without adversely affecting pH. This creates a more suitable environment for bioremediation of BOD and nutrients like nitrogen and phosphorus. Because magnesium supplies a light-weight, divalent cation, unlike the monovalent sodium in caustic, and heavier calcium in lime, Thioguard generates a denser, more easily dewatered sludge, with a higher percentage of cake solids – without the “bulking” commonly associated with Lime.

The Solution to Your F.O.G. Problem is THIOGUARD®

By Thioguard

The accumulation of fats, oils, and grease can be dramatically reduced through the use of THIOGUARD® technical grade magnesium hydroxide. THIOGUARD® is a strong base, and a moderate pH adjuster, which adds non-carbonate alkalinity to the wastewater. As pH increases, fats, oils, and grease become more soluble. The practical effect on municipal wastewater systems is a rapid, dramatic reduction in fat, oils, and grease buildup within the collection, transport and treatment structures.

 THIOGUARD® does NOT transfer F.O.G. problems “downstream,” only to reappear in your plant.

THIOGUARD® eliminates the problem, by improving the immediate environment, allowing “good bacteria” to perform their function. By the time the wastewater reaches your reclamation facility, the majority of the F.O.G. has been either consumed or reduced to simpler organics.

The addition of THIOGUARD® boosts pH levels, THROUGHOUT your system, PREVENTING the conditions that encourage the deposition of grease, which can clog lines, and accumulate on the surface of pump stations and your treatment plant. With improved pH, solubility is increased significantly, by a factor of 10x in some cases. THIOGUARD® is typically added through a single Feed Unit, and provides multiple benefits throughout your system, from source to discharge.

THIOGUARD® provides the greatest power to neutralize acid over long infrastructure distances, while providing additional benefits to your waste water treatment plant’s biological treatment processes. The chart below compares alkalinity per gallon, illustrating the superiority of THIOGUARD® against other commonly used treatment options.

THIOGUARD® Cuts through F.O.G. and Delivers
Multiple System-Wide Benefits

The benefits of adding THIOGUARD® to your treatment processes are not limited to the prevention or reduction of F.O.G., through sustainable and balanced pH levels. THIOGUARD® also prevents corrosion and dramatically reduces the formation of sludge – significantly reducing your handling and transportation costs. The benefits are numerous and system-wide, making THIOGUARD® the best and most practical choice for your system.

Thioguard is Superior to Lime Slurry and Caustic Soda

By Thioguard

POUND FOR POUND, THE BEST CHOICE

On the surface, it’s easy to do the theoretical calculations and provide exact alkaline equivalents. However, field and trial experience tells us something different. The amount of high grade Thioguard – magnesium hydroxide required to achieve equivalent buffering/performance benefits in the biological reactors tends to be much lower than the calculations would suggest. Why?

Often overlooked are some of the side impacts of lime use, such as softening and pH spikes, and confusion about what standard total alkalinity tests are telling us. An easy way to find out the extent of softening that is taking place in your facility, is to filter your sample with a 0.45 micron filter before titration. This will remove the insoluble CaCO3 particles that are not “biologically available.” Another significant, yet overlooked impact is the EPA documented sludge production typically associated with lime.

EPA – wastewater technology fact sheet – chemical precipitation: “the addition of treatment chemicals, especially lime, may increase volume of waste sludge up to 50%.”

 LIME SOFTENING = ALKALINITY REMOVAL

Lime is commonly used in potable water to “soften,” or remove hardness minerals, such as calcium and magnesium from drinking water, in an effort to minimize the effects of potential scaling in the water distribution system. However, in the softening process, calcium and magnesium are removed from water in the form of calcium carbonate (CaCO3) and magnesium carbonate (MgCO3) which are also forms of alkalinity. Removing hardness from water also removes alkalinity.

Lime SofteningIn wastewater, lime is often considered as an alkalinity supplement. However, the effects of lime softening can have undesirable consequences to the biological system, e.g., removal of alkalinity, creation of CaCO3 sludge, and the potential for bio-upsetting pH spikes.

Hot Zones Temperate ZonesThe simple fact: Thioguard and lime slurry have different physical and chemical properties that affect how each responds to and reacts with the systems to which they are added. And because of these differences in properties, the impacts they impart and the utility for their use are starkly different.

DID YOU KNOW…

  • Because of the high solubility of both caustic soda and lime, pH often becomes biologically prohibitive before ideal alkalinity levels and process stability can be reached.
  • The use of lime in, or prior to, primary treatment can actually reduce alkalinity going into the secondary treatment processes by precipitating CaCO3 in the primary clarifiers, or by converting bio-available soluble alkalinity into insoluble alkalinity in the biological reactors

Hydrated Lime added in collection systems increases O&M costs
related to formation of scale and accumulated solids/sludge.
In severe cases this leads to line blockages and SSO’s

The use of lime generates significant amounts of sludge in wastewater collection systems and treatment plants. On a chemical basis, one ton of lime can generate as much as 5 tons of 20% sludge cake to remove or dispose. In contrast, Thioguard reactions in wastewater produce only water and water-soluble products as TDS with NO added sludge. In fact, customers using Thioguard have reported reductions of 15%-25% in total solids/sludge produced, due to a combination of improved biological performance, divalent cation bridging of floc matrix, and reduced inorganic solids loading.

Most wastewater treatment plant operators understand that their wastewater treatment plants function best at some ideal pH and that a minimum amount of alkalinity is required to keep microorganisms happy. But too often, the values of pH and alkalinity are incorrectly used interchangeably, and a thorough understanding of each parameter’s true relationship to biological stability and optimal performance – gets lost in the translation.

Most often this error in terminology stems from the use of the most common alkaline pH modifiers and alkalinity supplements, caustic soda and lime, where their use may successfully meet pH demands, but will likely fall short in supplying adequate alkalinity requirements without adversely elevating pH beyond biologically healthy limits. And often, maintaining pH stability and uniformity across entire treatment basins remains a virtual impossibility.

Compared to caustic soda or lime, Thioguard is capable of supplying significantly more alkalinity in a bio-available form to a microbial wastewater system without adversely affecting pH. This creates a more suitable environment for bioremediation of BOD and nutrients like nitrogen and phosphorus. Moreover, because magnesium supplies a light-weight, divalent cation, unlike the monovalent sodium in caustic, and heavier calcium in lime, Thioguard helps to generate a denser, more easily dewatered sludge, with a higher percentage of cake solids.

Lb.s Alkalinity Per Gallon

DID YOU KNOW…

  • It takes 100+ mg/L of Thioguard to raise a water sample to pH 8.8.
  • This same 100 mg/L of Thioguard has the same neutralizing power as 138 mg/L of caustic soda and 135 mg/L of lime and would be the equivalent of, though significantly more reactive than, adding 172 mg/ L calcium carbonate alkalinity on a CaCO3 basis, assuming 100% bicarbonate conversion.

Thioguard Reactor systems treated to an initial pH of 8.5 using Thioguard, caustic soda and lime.Equivalent amounts of acid added to each over time.
