Publication number: 20140374348Abstract: The invention describes a method for treating sewage sludge through the treatment steps of hydrolysing (2) the sewage sludge (1) and digesting (11) the hydrolysed sewage sludge (10), which has undergone hydrolysis (2), for the anaerobic treatment of the sewage sludge (1), and through the step of separating phosphate from the at least partially treated sewage sludge (3). Phosphate is separated after the treatment step of hydrolysing (2) and before the treatment step of digesting (11) the hydrolysed sewage sludge (3), wherein the sewage sludge (10), without the phosphate portion separated in the phosphate separation step, is fed to the anaerobic treatment performed through digestion (11).Type: ApplicationFiled: September 10, 2012Publication date: December 25, 2014Applicant: P.C.S.

Publication number: 20140360889Abstract: Embodiments of systems, devices, and methods for treating, remediating, or abating carbon-containing wastes generate at least one of clean water; non-toxic, non-hazardous ash; or power. Some embodiments are modular, permitting rapid deployment, flexible configuration, and easy transportation. Embodiments of the systems treat carbon-containing aqueous waste, carbon containing waste, or a combination thereof. The systems, devices, and methods are particularly suited to treating hydrocarbon containing waste generated in oil and natural gas drilling and hydrofracturing.Type: ApplicationFiled: February 6, 2013Publication date: December 11, 2014Inventors: Coyte R. Jones, Robert C. Jones

Publication number: 20140360944Abstract: The invention relates to a system and method for obtaining a cellular fraction enriched with defined cells effective in promoting a defined cellular response from an in vivo cellular sample comprising: a collection tube for collecting a cell suspension (1), an anticoagulant portion (4), a portion of separation gel (3), a first collection syringe for collecting a cell depleted fluid (10), a second collection syringe for collecting the enriched cellular portion (11) and at least one needle (1O) for attaching to each syringe. The system is closable to the atmosphere, further wherein the cell suspension collection tube contains the gel (3) and the anticoagulant (4), the tube is adapted such that, when containing cell suspension and centrifuged after treatment yields separation fractions, a first fraction comprising cellular fluid (6), a second fraction comprises gel layer (3), a third fraction comprises enriched cellular portion (7) on top of the gel layer and a fourth fraction comprises a cell poor portion (8).Type: ApplicationFiled: January 23, 2013Publication date: December 11, 2014Inventor: Aaron Esteron
