20160059211 | Mesoporous Activated Carbon - Mesoporous activated carbon having a mesopore structure of at least about 10%. In at least some embodiments, the activated carbon may be coconut shell-based. The enhanced activated carbon may have an intraparticle diffusion constant of at least about 40 mg/g/hr | 03-03-2016 |
20150233867 | System for Measuring the Concentration of Magnetic Ballast in a Slurry - A system and method for measuring the concentration of magnetic ballast in a slurry to be analyzed is provided. A detection conduit is provided and configured to receive a slurry to be analyzed. The detection conduit may be surrounded by a set of detection coaxial coils. A reference set of two coaxial coils is also provided. A power source is provided for establishing an electrical current. A measurement subsystem for measuring the differential induced voltage between detection and reference coils is provided to determine the concentration of the magnetic ballast in the slurry. | 08-20-2015 |
20150225268 | LOW SCALE POTENTIAL WATER TREATMENT - An electrochemical treating device having low scale potential is disclosed. The device has a variety of configurations directed to the layering of the anionic exchange and cationic exchange. The treatment device can also comprise unevenly sized ion exchange resin beads and/or have at least one compartment that provides a dominating resistance that results in a uniform current distribution throughout the apparatus. | 08-13-2015 |
20140263010 | 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. | 09-18-2014 |
20140238932 | ENHANCED BIOSORPTION OF WASTEWATER ORGANICS USING DISSOLVED AIR FLOTATION WITH SOLIDS RECYCLE - Systems and methods for treating wastewater including a dissolved air flotation operation performed upon a portion of a mixed liquor output from a contact tank prior to the mixed liquor entering a biological treatment tank. | 08-28-2014 |
20140217015 | USE OF PRIMARY SLUDGE FOR CARBON SOURCE IN AN AERATED-ANOXIC BIOREACTOR SYSTEM - A method and system of treating wastewater using primary sludge is disclosed. The treatment system includes a primary separator that separates a carbon source comprising non-solubilized suspended carbon from a source of wastewater. The non-solubilized suspended carbon is solubilized and used as a source of carbon in an aerated anoxic treatment system. | 08-07-2014 |
20140216934 | ELECTROCHEMICAL DESALINATION FOR OIL RECOVERY - Electrically-driven separation systems and methods for use in oil recovery. | 08-07-2014 |
