Abstract: A process for treatment of municipal wastewater plant sludge to the criteria of Class A biosolids. The process uses hydrogen peroxide and thermo-oxidation to reduce volatile suspended solids to meet the criteria. On a batch basis, waste activated sludge is introduced into a reactor; the concentration of the waste activated sludge is adjusted to about 1.5% total suspended solids with secondary effluent, if necessary; the reactor is mixed; the reactor is pre-heated to an operating temperature in a range of about 65° C. to about 90° C.; subsequently, a 50% solution of laboratory grade hydrogen peroxide is introduced into the bottom of the reactor; and the contents are heated for at least 4 hours.

Abstract: A gravity-flow Biomass Concentrator Reactor (BCR) is provided which uses a porous barrier having pore sizes averaging from about 1 to about 50 microns through which treated water permeates under the pressure of gravity. Solids suspended in water treated with the BCR are effectively retained and concentrated.

Abstract: A process for the immobilization of a catalyst, in particular an oxidation or synthesis catalyst, on supports making it possible to bring said catalysts into contact with solutions or liquids being treated, characterized in that the deposition of the catalyst is carried out by:
