Presentation on Biochemical ETP 5
Effluent is the stream of excess chemical liquor which is extracted from an industry after using in original operation.
The excess dye liquor which is extracted from textile industry after dyeing from different processes are treated with various chemicals to remove or neutralize the toxic materials before discharging to environment (e,g- ground water) . This is called effluent treatment.

Screening is the filtration process for the separation of coarse particles from influent.
Stainless steel net is used for screening.
Hard plastic brushes are used to clean the net, which are driven mechanically.

Sequencing batch reactors are industrial processing tanks for the treatment of wastewater . SBR reactors treat waste water from industrial area, and sewage or output from anaerobic digesters or mechanical biochemical and biological treatment facilities in batches,
Oxygen is bubble through the waste water to reduce Biochemical oxygen demand (BOD) , chemical oxygen demand (COD) to make suitable for use in land and aquatic life. Here used bacteria should be aerobic,

At first we want to give thanks to our honorable course teacher
Assistant professor Dr. Arun Kanti Guha, for assigning us for this important assignment and also for his immense help in during making this assignment paper. We also want to pay thanks to our senior brother Mazedul Hasan Shishir (13th batch) for his help and support.
At last we want to pay thanks to our group members for help and co-operation with hard working mentality so that we could complete the task with success.
