Municipal wastewater treatment ; Wastewater ; Cyclic activated-sludge technology
Use advice for data set Users of this data set should account for geographical and technological relevance of the process to the regional context of the application. Since the data is specific to the Chatuchak area in Thailand, adjustments may be needed for differing technological standards, local environmental regulations, or wastewater composition when applying this data to other regions. Additionally, users should consider the boundaries of the unit process defining what is included in the system ('black-box' approach) and what falls outside its scope.
Technical purpose of product or process The Cyclic Activated-Sludge Technology described in this data set is used for municipal wastewater treatment to remove contaminants and produce environmentally safe treated wastewater. It is typically implemented as a part of municipal wastewater treatment plants.

General comment on data set Cyclic activated sludge process is a new type of wastewater biological treatment process developed on the basis of SBR technology, the application of this method is based on the combination of social development and advanced science and technology based on a comprehensive sewage treatment collection measures and treatment processes, and in its work there are good working advantages and a wide range of applications. Up to now, many of our country's sewage treatment plant in the work of this process will be incorporated as the primary work technology for application.

Technological representativeness
Technology description including background system Recirculating activated sludge technology consists of the following processes:Intake and mixing: wastewater is introduced into the treatment system and mixed with activated sludge already present in the reactor.Biodegradation: The mixed wastewater comes into contact with the activated sludge in the reactor, where microorganisms degrade the organic substances in the wastewater into water and carbon dioxide.Sedimentation: The treated water is settled over a period of time so that the sludge particles settle to the bottom to form sludge deposits.Return flow: A part of the activated sludge that has been settled is returned to the reactor to maintain the number and activity of microorganisms in the sludge.Discharge: The treated water is discharged through the outlet and the clean water is released into the environment.
