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 and apparatus for reducing the footprint of chemical/mechanical/biological wastewater treatment facilities employing sulfur dioxide disinfection and chemical dewatering of solids in conjunction with an environmental biological systems for treating the separated treated wastewater.

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 compound and a method of forming a photopolymerizable acrylated glycidyl acrylic terpolymer resin compound is disclosed. The polymeric resin may be formed in a two-step process. A photopolymerizable acrylic hybrid polymer is suitable for forming films having glass transition temperatures from about −55 degrees C. to about 110 degrees C. A non-aromatic photopolymerizable acrylate polymer may be formed by combining, in a first step, a reactive source of epoxide ion groups. In a second step, the glycidyl acrylic terpolymer formed in the first step is reacted with a catalyst and a source of unsaturated acid or anhydride to form an acrylate polymer. A ring opening reaction is employed such that an acid or an anhydride containing a conjugated double bond forms an acrylated acrylic, an acrylated fluorinated acrylic, an acrylated silonted acrylic, or an acrylated halogenated grafted acrylic. The cure process is initiated with specific UV or visible light promotors and/or with a UV or visible light source.
