COMPUTER-AIDED SYNTHESIS OF WASTEWATER TREATMENT AND SLUDGE DISPOSAL.A computer-aided design procedure for the preliminary synthesis of wastewater treatment and sludge disposal systems is developed. It selects the components in the wastewater treatment and sludge disposal trains from a list of candidate process units with fixed design characteristics so that criteria on effluent quality, cost, energy, land utilization, and subjective undesirability are best

3 Municipal Wastewater and Sludge Treatment - US EPA

At municipal wastewater treatment plants in the United States, raw municipal wastewater undergoes preliminary, primary, secondary, and in some cases, additional treatment to yield treated effluent and a concentrated stream of solids in liquid, called sludge.

from wastewater sludge and tested them for antibiotic resistance and R-plasmid transfer. Almost 62% of these bacteria were resistant to at least one antibiotic tested. Organic extracts from sewage sludge were bioassayed for microbial mutagenic re sponse as well as chemically analyzed by high resolution gas chromatography.49

and water separate. Wastewater then moves to other treatment processes while sludge is removed. Part of it is returned to the ditch as RAS, while the rest is removed from the process as the waste activated sludge (WAS). WAS is wasted either continuously or daily and must be stabilized prior to disposal or beneficial reuse. APPLICABILITY

CHAPTER 12 Sludge Processing and Disposal - TN.gov

Sludge is a broad term used to describe the various aqueous suspensions of solids encountered during treatment of sewage. The nature and concentration of the solids control the processing characteristics of the sludge. Grit screenings and scum are not normally considered as sludge and therefore are not discussed in this section.

Computer-Aided Synthesis of Wastewater Treatment and Sludge

The most frequently encountered problem in wastewater treatment plant design is the tendancy to optimize a given subsystem, such as sludge dewatering, without considering the side effects of this optimization on the overall plant operation and treatment costs.
