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.
