Available in PDF, EPUB and Kindle. Book excerpt: To aid in the further development of sewage treatment by activated sludge, a continuous flow automatically recording respirometer was used to study the response of aeration only and aeration with sludge return completely mixed activated sludge systems (CMAS) to step changes in the influent substrate. The experiments were conducted at 25 C with glucose; a mixture of glucose, glutamate, and acetate; and a mixture of sewage solids plus Metrecal. Influent substrate concentrations were doubled in the 3-hour and tripled in the 6-hour mean residence time aeration only experiments without increasing the soluble COD in the effluent. Decreases in the influent substrate concentrations produced rapid decreases in the rate of oxygen utilization. A procedure for calculating the rate of oxygen uptake by a CMAS system at any time during a step transient was developed.

This book was released on 1972 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade, research has been conducted to produce a general body of conceptual principles applicable to design and operation of activated sludge processes. The aid of the report is to present these biological concepts in terms readily understood by engineering professionals. Generalized concepts of BOD exertion, the use of the measure of biologically available organic matter in a waste sample as a design and operational tool, the stoichiometry and mass balance concepts of treatment, and kinetic equations for microbial growth are presented. Design models are discussed, and a model for completely mixed reactors holding recycle solids, X(R), constant is recommended. Some guidelines for accommodation of various types of shock loadings are included. Concepts of oxidative assimilation and the multiple effects of solids concentration, nitrogen concentration, and detention time are related; a new activated sludge process (continuous oxidative assimilation) for nitrogen-deficient wastes is presented. Data supporting the concept of total oxidation are presented. Some possible flow diagrams for complete aerobic treatment (purification and sludge disposal) of metabolizable organic wastes are presented.

Available in PDF, EPUB and Kindle. Book excerpt: Activated sludge is the most widely used biological wastewater treatment process in the world, both for domestic and industrial purposes. This book reviews the major theoretical concepts and practical operational factors, and describes the complexities inherent in the process, which depends on a dense microbial population mixed in wastewater under specific aerobic conditions. It is an ideal reference source for scientists, and a useful troubleshooting guide for practicing engineers and plant operators.

This book was released on 1972 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: A process (called UNOX) for treating municipal wastewater using high-purity oxygen in the activated sludge process was further evaluated at Batavia, New York in a full scale wastewater treatment plant. The present evaluation places emphasis on the production rate, filtration, and digestion characteristics of oxygenated waste activated sludge. Operation was conducted at two different system loadings over a period of three months. The filtering characteristics of waste activated sludge from an oxygenation system were investigated. Waste activated sludge was aerobically digested in 800-gallon batches using high-purity oxygen. The economics of oxygenation systems as compared with conventional diffused air aeration systems were revised from the cost estimates presented in initial work.
