Summary 20-40% Dryer Press Cake, plus increased pH = better performance 100 mg/L compared to 135 mg/L lime and 138 mg/L of caustic soda Cations? Thioguard alkalnity to make wastewater more treatable and improves biosolids Thioguard vs Caustic Soda/Lime Slurry 15%-25% reduction in solids/sludge. No pH "spikes" and greater efficiency Thioguard in my System 75% becomes water. Cations and OH-anions provide double benefit Case Study Tyler, TX Improved Biological process Lower Disposal Costs   Thioguard® TST - Magnesium Hydroxide "milk of magnesia" Mg(OH)2 The Non-Hazardous, Earth-Friendly alternative for odor and corrosion with positive plant benefits.   Long distance H2S hydrogen sulfide and sulfuric acid corrosion reduction through:   Low Solubility 0.0009 g/100ml, H2O solubility and high surface area of 1 acre per gallon provides long distance collection system treatment to and through the wastewater treatment plant SRB Inhibition Reduces the ability of sulfate reducing bacteria (SRB) to convert sulfates to hydrogen sulfide gas Magnesium Polysulfide Complexation Promotes complexation between magnesium cation and sulfides by absorbing dissolved sulfides onto the solid magnesium hydroxide particle Henry's Law Gas/Liquid Phase Equilibrium - resulting increase in pH keeps the the dissolved hydrogen sulfide gas in solution   Wastewater Treatment Plant Process Improvements through:   pH and Alkalinity Supplementation 0.0009 g/100ml, H2O solubility and high surface area of 1 acre per gallon provides long distance collection system treatment to and through the wastewater treatment plant 1 mg/L ammonia-N requires 5.50 mg/L NaOH caustic soda or 4.16 mg/L Mg(OH)2 for effective nitrification With the addition of a slowly dissolving low solubility 0.0009 g/100ml, H2O particle THIOGUARD®'s use in aerobic and anaerobic biological digestors provides a steady reactor pH conducive for maximizing bacterial development Negatively charged microbial flora are bridged by the divalent positive charge of magnesium hydroxide forming a large floc that settles readily Biosolids Chemistry Enhancement for Land Application Available magnesium in soil occupies the central position of the chlorophyll molecule/green pigment to utilize solar energy for the production of organic matter. Therefore, an adequate magnesium supply to plants may markedly increase photsynthetic activity of leaves. Also, magnesium is essential to energy (vitamin) transfer within plants Increasing filter cake solids by 20-40% due to divalent cation bridging Improvements in floc formation and thereby significantly reducing polymer demands     © 2011 Premier Magnesia, LLC | Thioguard Headquarters | 300 Barr Harbor Suite 250 | West Conshohocken, PA 19428
