Abstract: A pre-treatment method injecting sulfur dioxide into waters containing suspended solids to undergo ultra violet disinfection to form sulfurous acid (H2SO3) to self-agglomerate and precipitate solids from the wastewater for settling or filtration removal and provide acid to reduce bicarbonate and mineral scaling and microbial buildup on ultraviolet light tubes to improve their performance.

Abstract: A method of conditioning, separating, drying, and comminuting sulfurous acid treated wastewater suspended solids for addition to aerobic and anaerobic digesters to provide electron donor carbon and sulfur compounds to increase the removal rate of ammonia, nitrates/nitrites, and BOD compounds.

Abstract: A method for treating ballast water with sulfurous acid to kill invasive species and remove oxygen from the ballast water to preserve hulls from rusting.

Abstract: A method for cleaning and maintaining reverse osmosis membrane filters by injecting sulfurous acid into water to form sulfurous acid (H2SO3), and then sequentially filtering the acidified water through membrane filters to reduce alkalinity and mineral scaling, add sufficient SO2 as a biocide to attack bacteria and other micro organisms to prevent membrane fouling, reduce iron to prevent iron deposit build-up, scavenge and remove dissolved oxygen prior to filtration to prevent membrane oxidation, and prevent concentrated salts within the retentate from precipitating out of solution during transport for land application.

Abstract: An apparatus for burning sulfur to produce sulfur dioxide, which sulfur dioxide is associated with a multi-channel gas valve associated with other gas sources to selectively be blended each into water by a combination mixer/aerator to aerate water in one monde, admix sulfur dioxide with water to form sulfurous acid in another mode, and stir and mix water without gases in a third mode.

Abstract: A wastewater treatment method employing chemicals for disinfection, and precipitation of suspended solids, heavy metals and phosphates before subsequent aerobic bacterial biological treatment using Nitrosomonas and Nitrobacter bacteria to remove ammonia and nitrates/nitrites and BOD compounds to produce recovered treated wastewater suitable for open water discharge.

Abstract: A method for acidifying saline waters for raising plants, comprising injecting sulfur dioxide to form a sufficient amount of sulfurous acid treated saline waters until these buffered acidified waters condition the surface membranes of plant roots to selectively take in water and ions needed for metabolism, while filtering others out to enable the plant to withstand and live in a high salt aqueous environment.

Abstract: A wastewater treatment method employing chemicals for disinfection, and precipitation of suspended solids, heavy metals and phosphates before subsequent aerobic bacterial biological treatment using Nitrosomonas and Nitrobacter bacteria to remove ammonia and nitrates/nitrites and BOD compounds to produce recovered treated wastewater suitable for open water discharge.

Abstract: A chemical/biological wastewater treatment apparatus employing rapid sludge chemical dewatering technology in conjunction with an environmental biological system for treating the separated treated wastewater by land applying it for the propagation of biosynthetic fuels and other plants; and/or passing it through aqueous plant, algae, or microbial reduction of the dissolved solids and ammonia for BOD compliance to produce water of sufficient quality to meet open stream and ocean effluent discharge requirements; and disposing of the high BTU low moisture solids.

Abstract: A pre-treatment method for cleaning and maintaining reverse osmosis membrane filters by injecting sulfurous acid into waters with suspended solids in a liquid fraction to be filtered to form sulfurous acid (H2SO3) to acid leach heavy metals into the liquid fraction, reduce alkalinity and mineral scaling, add sufficient SO2 as a biocide to attack bacteria and other micro organisms to prevent membrane fouling, reduce iron to prevent iron deposit build-up, scavenge and remove dissolved oxygen prior to filtration to prevent membrane oxidation, and then sequentially filtering the acidified water through membrane filters to create a metal free permeate and a brine retentate, which can be pH adjusted to remove the heavy metals as metal hydroxide precipitates.

Abstract: A treatment method for wastewater employing sulfur dioxide and lime chemical dewatering technology in conjunction with an environmental photo biomass/algae biological treatment system growing photo biomass/algae to reduce dissolved solids, heavy metals, and ammonia in the wastewater to produce recovered treated wastewater for vegetation consumption, biofuel feedstock, and biofuel and carbon credits.

Abstract: A sulfurous acid/alkalinization pre-treatment method for wastewaters to condition and remove a number of chemicals/pharmaceuticals and heavy metals before the recovered treated influent undergoes further biological reduction via anaerobic and aerobic digestion.

Abstract: A method to create a net increase in soil organic carbon (SOC) by acidifying land applied waters with pH adjusted sulfur dioxide to open up soil pores at greater depths, while providing sulfur and other nutrients to plants and soil bacteria to stimulate and increase their overall grow and their assimilation of carbon dioxide to sequester a greater net volume increase of soil organic carbon (SOC).

Abstract: An apparatus for burning sulfur to produce sulfur dioxide, which sulfur dioxide is associated with a multi-channel gas valve associated with other gas sources to selectively be blended each into water by a combination mixer/aerator to aerate water in one monde, admix sulfur dioxide with water to form sulfurous acid in another mode, and stir and mix water without gases in a third mode.

Abstract: A hybrid chemical/mechanical water treatment plant and method employing rapid sulfur dioxide chemical disinfection and dewatering technology in conjunction with lime and oxidization/reduction agents to removal pharmaceuticals and personal care products from waters to meet operating constraints and environmental permitting restrictions and siting limitations for water treatment.

Abstract: A hybrid chemical/mechanical dewatering sewage treatment plant and method employing rapid sludge chemical dewatering technology in conjunction with slower conventional mechanical dewatering solids agglomeration and disposal methods to meet operating constraints and environmental permitting restrictions and siting limitations for disposal of sewage and wastewater.

Abstract: A sulfurous acid treated wastewater disposal method employing soil aquifer treatment (SAT) for artificial recharge of groundwater through infiltration basins allowing fully or partially-treated sewage effluent to infiltrate into the soil and move down to the groundwater through a “vadose” zone, which acts as a natural filter to remove essentially all suspended solids, biodegradable materials, bacteria, viruses, and other microorganisms.

Abstract: A method to create a net increase in soil organic carbon (SOC) by acidifying land applied waters with pH adjusted sulfur dioxide to open up soil pores at greater depths, while providing sulfur and other nutrients to plants and soil bacteria to stimulate and increase their overall grow and their assimilation of carbon dioxide to sequester a greater net volume increase of soil organic carbon (SOC).
