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.
