| 20080314827 | Hybrid chemical/mechanical dewatering method and apparatus for inactivating and removing pharmaceuticals and other contaminants from wastewater - 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. | 12-25-2008 |
| 20090045120 | Wastewater chemical/biological treatment method and apparatus - A chemical/biological wastewater treatment plant apparatus and treatment method 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 or microbial reduction of the dissolved solids and ammonia for BOD compliance to produce water of sufficient quality to reduce the overall salt load currently being added by wastewater treatment facilities into natural waterways, and to produce water of sufficient quality to meet open stream and ocean effluent discharge requirements; and disposing of the high BTU low moisture solids. | 02-19-2009 |
| 20090255863 | Wastewater treatment apparatus - 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. | 10-15-2009 |
| 20090294354 | Wastewater photo biomass/algae treatment method - 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. | 12-03-2009 |
| 20100193429 | Method and apparatus to reduce wastewater treatment plant footprints and costs - 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. | 08-05-2010 |
| 20100193436 | Pre-treatment reverse osmosis water recovery method for brine retentate metals removal - 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 (H | 08-05-2010 |
| 20100230363 | Groundwater recharging wastewater disposal method and apparatus - 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. | 09-16-2010 |
| 20110027017 | Carbon sequestration method - 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). | 02-03-2011 |
