| 20110042320 | TREATMENT OF CONTAMINATED WATER FROM GAS WELLS - Systems and methods for treating contaminated water from gas wells by adding an inorganic coagulant and a low molecular weight polymer to the contaminated water to increase the size of solid particulates in the water and to thereby allow the solid particulates to be filtered or to otherwise be removed from the water are disclosed herein. While the inorganic coagulant can be any suitable coagulant, in some cases the coagulant is selected from aluminum chlorohydrate, polyaluminum chloride, aluminum sulfate, and ferric sulfate. Similarly, the polymer can comprise any suitable polymer, such as epi/dma, a condensation product of epichlorohydrin and dimethyl amine. The described systems and methods can clean the contaminated water so that the water can then be treated in a variety of other manners, which may include reverse osmosis, deionization, treatment with mixed bed deionizers, electro-separation, fraction distillation, distillation, and other suitable water cleansing processes. | 02-24-2011 |
| 20100032370 | ANAEROBIC DIGESTER DESIGN AND OPERATION - An apparatus for the anaerobic digestion of solid waste is disclosed. The apparatus includes a pre-digestion treatment chamber and an anaerobic digester chamber coupled to the pre-digestion treatment chamber. A liquid suspension of solid waste is pretreated under aerobic conditions by heating to a desired pre-digestion temperature. One or more chemical or biological additives are added to the suspension of solid waste to improve the anaerobic digestibility of the solid waste. This may include enzymes to destruct poorly digestible solids and/or materials to provide a desired C:N ratio in the solid waste. The apparatus may include mixers, heaters, chemical or biological additives as needed, various sensors and probes, and a control system to monitor and control the anaerobic digestion process and maintain microbial health of the digester. | 02-11-2010 |
| 20090211982 | PROCESS FOR TREATING EFFLUENT LIQUID FRACTION FROM POST ANAEROBIC DIGESTION - A process for treating a liquid fraction of effluent wastewater from post anaerobic digestion containing fine solids having a size less than about 25 microns is disclosed. A metal salt flocculant is added to the liquid fraction in an amount ranging from about 50 to 500 ppm in the liquid fraction. The metal salt flocculant is selected from inorganic iron and aluminum flocculent compounds having a +2 or +3 valence. A cationic organic polymer is added to the liquid fraction in an amount ranging from about 10 to about 150 ppm in the liquid fraction. The cationic organic polymer has a molecular weight greater than about 3,000,000 and cationicity in the range form 1.25 mole % to 30 mole %. The metal salt flocculent and the cationic organic polymer produce a separable solid fraction which is recovered. Pre-treatment with a small amount of the cationic organic polymer provides improved results. | 08-27-2009 |
