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 flow imaging and monitoring system for synchronized management of wide area drainage that includes an interposer for supporting monitoring and management equipment in a manhole, a module for illuminating water flowing in pipes at the base of the manhole, a module for monitoring responses to reflected light, a sealed and rechargeable battery pack, and a data analysis and management system to interpret data streams in real time. The interposer can be adjusted to fit the diameter of the manhole and can be adjusted to be placed under the manhole cover. The module for illuminating the flowing water can be adjusted to generate various frequencies. The support structures for the modules can be adjusted for varying pitch, roll and yaw with respect to the manhole. The data analysis and management system is supported by cloud computing.
