Abstract: In the field of water treatment, this invention relates to economical methods, processes and apparatus for preparing Class A bio-solids wherein: dewatering costs and energy costs are efficient, the solids product has reduced ammonia and sulfide odor, and the concentration of solids in the aqueous solids may vary from approximately 3 to approximately 90 percent. This invention presents mesMophilic and thermophilic digestion in concert, wherein mesophilic digestion incorporates strains of Thiobacillus with nitrifiers to remove sulfide(s) and ammonia from bio-solids. Chemical dewatering of thermophilic digested bio-solids is accomplished incorporating a cationic, quatemized or an anionic polyacrylamide with at least one selected from a list consisting of: an aluminum salt, an iron salt, an amine comprising a quatemized nitrogen moiety and any combination therein. A quatemized polyacrylamide is presented alone.

Abstract: As population density increases, the transportation of hazardous chemicals, including acids and disinfectants, lead to an increased incidence of spills while the consequences of spills become more serious. While solutions of halide acids, hypohalites and halites are safer disinfectants for transportation, handling, storage and use than traditional gaseous chlorine, the manufacturing cost of these disinfectants has here-to-fore limited their use. Economical processes are presented for the manufacture of O2, halogen oxides, halide acids, hypohalites, and halates; as well as polynucleate metal compounds, metal hydroxides and calcium sulfate hydrate (gypsum). The instant invention presents methods and processes that incorporate the use of sulfur. This is while environmental regulators, such as the US EPA, require an increased removal of sulfur from hydrocarbon fuels, thereby creating an abundance of sulfur, such that the refining industry is in need of a way to dispose of said abundance of sulfur.

Abstract: This invention presents improved combustion methods, systems, engines and apparatus utilizing H2, O2 and H2O as fuel, thereby providing environmentally friendly combustion products, as well as improved fuel and energy management methods, systems, engines and apparatus. The Water Combustion Technology; WCT, is based upon water (H2O) chemistry, more specifically H2O combustion chemistry and thermodynamics. WCT does not use any hydrocarbon fuel source, rather the WCT uses H2 preferably with O2 and secondarily with air. The WCT significantly improves the thermodynamics of combustion, thereby significantly improving the efficiency of combustion, utilizing the first and second laws of thermodynamics. The WCT preferably controls combustion temperature with H2O and secondarily with air in the combustion chamber. The WCT preferably recycles exhaust gas energy as fuel converted from water.
