Jun 16, 2019· Meaning Activated Sludge Process. The activated sludge process is one of the biological method of industrial waste waste treatment. The activated sludge process consists of converting the suspended and particulate organic matter in the raw waste water into harmless end products and new cells growth with the help of Anaerobic and Aerobic Microorganisms.

In larger plants separate sludge pre thickening is economically viable, but this is not true for most plants of less than m3/s (5 mgd). [Over 95 percent of the sewage treatment plants in the United States are less than rr>3/s ( 5 mgd)].
wastewater treatment Preface The wastewater treatment lectures are designed to provide insight into the processes and techniques that are applied in the wastewater treatment fi eld, where the focus is laid on the basic principles, local conditions, basic circumstances and performance processes. Their mutual relationship is also explained.
Activated sludge is also the name given to the active biological material produced by activated sludge plants. Excess sludge is called "surplus activated sludge" or "waste activated sludge" and is removed from the treatment process to keep the ratio of biomass to food supplied in the wastewater in balance.
