Sequencing batch reactor (SBR) systems were used for the development of a system and operating procedures for the high production and storage of polyhydroxyalkanoates (PHAs) by wastewater treatment (activated sludge) bacterial cultures. The systems were maintained at a nominal hydraulic retention time (HRT) of 10 hours, and a temperature of 20°C. The solids retention time (SRT) was maintained a...

Abstract The pulping industry generates vast amounts of bark and wastewater treatment sludges, which are combined stored in stacks, often the open air, prior to combustion for energy. effects incorporating sludge into on heating value storage-related environmental impacts were investigated laboratory outdoors. Biological degradation was found be higher treatments containing 25% (B75S25) 50% (B5...

The aim of this paper is to show possibilities for effective processing of hazardous waste using the vitrification method, which is recommended for disposing of ash from the combustion of sewage sludge and developing a process for the conversion of waste to a sustainable and environmentally safe product. The use of vitrification solves the problem of utilizing some hazardous waste by simultaneo...

A new method for the isolation of Cryptosporidium parvum oocysts and Giardia lamblia cysts from biosolid samples has been developed that utilizes sedimentation and immunomagnetic separation. The method was used to recover stained cysts and oocysts (spike organisms) from primary settled sewage sludge, anaerobically digested sewage sludge, and bovine manure. Recovery efficiencies associated with ...

The activated sludge model No. 3 (ASM3) was modified to describe the biological reactions in aerobic granular sludge SBR. The simultaneous storage and growth, nitrification and denitrification were all accounted for in modified model. The sensitivities of effluent COD, NH(4)(+) -N, and TN toward the stoichiometric and kinetic coefficients were analyzed. A standard set of parameters obtained fro...
