20140183045 | Electrodesalination System and Method - Systems and methods for the desalination of seawater or brackish water for the purpose of obtaining potable water. Systems may include a combination of electrodialysis and electrodeionization modules. The system configuration and process controls may achieve low energy consumption and stable operation. | 07-03-2014 |
20140102977 | BALLASTED ANAEROBIC METHOD FOR TREATING WASTEWATER - A ballasted anaerobic system for treating wastewater including at least one anaerobic treatment reactor. A weighting agent impregnation subsystem is configured to mix weighting agent with the biological flocs to form weighted biological flocs to create a weighted anaerobic sludge blanket in the at least one anaerobic treatment reactor. A weighting agent recovery subsystem is configured to recover the weighting agent from excess sludge and reintroduce the weighting agent to the weighting agent impregnation subsystem. | 04-17-2014 |
20140086822 | CHLORINE DIOXIDE GENERATION SYSTEMS AND METHODS - Chlorine dioxide generation systems and methods are disclosed. In some embodiments, an optical analyzer may be positioned along a reactant feed line to measure a reactant concentration. A controller may adjust a flow rate of the reactant in response to information provided by the optical analyzer. | 03-27-2014 |
20140084511 | Membrane Potting Methods - Apparatus and methods are disclosed which reduce stress formation in potting heads for porous hollow filtration membranes. In one example, there is disclosed a potting sleeve for forming a potting head which includes a first fixed portion and a second portion which is movable relative to the first fixed portion to reduce a peripheral extent thereof. In another example, a method of mounting a porous hollow membrane in a membrane filtration apparatus includes positioning a portion of porous hollow membranes within a mold and introducing a curable potting material into the mold so as to immerse the portion of the porous hollow membranes and at least part of one or more deformable members in the potting material. The method further includes at least partially curing the potting material to form a potting head and removing the potting head and the one or more deformable members from the mold. | 03-27-2014 |
20140083940 | MEMBRANE CLEANING WITH PULSED AIRLIFT PUMP - A method of cleaning a membrane surface immersed in a liquid medium with a fluid flow, including the steps of providing a randomly generated intermittent or pulsed fluid flow along the membrane surface to dislodge fouling materials therefrom. A membrane module is also disclosed comprising a plurality of porous membranes ( | 03-27-2014 |
20140027374 | HYBRID AEROBIC AND ANAEROBIC WASTEWATER AND SLUDGE TREATMENT SYSTEMS AND METHODS - A hybrid method and system of treating wastewater with reduced energy usage is disclosed. The treatment system has a sorption system, an anaerobic digester that digests or converts at least a portion of the solids or sludge from the sorption system, and an aerobic treatment tank that partially reduces oxygen demand of a portion of the sludge from the sorption tank. | 01-30-2014 |
20140021130 | HYBRID AEROBIC AND ANAEROBIC WASTEWATER AND SLUDGE TREATMENT SYSTEMS AND METHODS - A hybrid method and system of treating wastewater with reduced energy usage is disclosed. The treatment system has a sorption system, an anaerobic digester that digests or converts at least a portion of the solids or sludge from the sorption system, and an aerobic treatment tank that partially reduces oxygen demand of a portion of the sludge from the sorption tank. | 01-23-2014 |
