TOTAL WATER & WASTE WATER ENVIRONMENTAL MANAGEMENT SOLUTIONS & SERVIVES.E. SCHEME DESCRIPTION :- For your Sewage Treatment Plant needs, we offer a system based on Extended Aeration system with details enclosed here with (EA) technology because as per technical considerations EA system is best suited to treat the kind of wastewater generated by your unit in 15 hrs operation. Extended Aeration process is an improvement over the conventional activated sludge process. It is a time proven, mature, conservative process of waste water treatment. Extended aeration plants are one the most basic sewage treatment techno lies and probably one of the most versatile methods available. EA plants are suitable for most waste water and economical to install and operate. Advantages and Key Features- Simple & Low cost design.- Flexible process that treat a wide range of waste water.- Good response to variable flow and speed.- Able to handle high SS load.- Ease of installation, operation and maintenance.In aeration tank (Extended Aeration) suspended microbial growth is maintained for the biological oxidation of organics. Diffused aeration is provided to meet the oxygen requirement of microorganisms and to keep the liquor in a completely mixed regime. The process units in an extended variation plant include:- Collection & Transfer of the raw wastewater viz. effluent into Aeration Tank (after Equalization).- Aerobic Treatment of mixed liquor in Aeration Tank.- Clarification of aerated mixed liquor in Secondary Clarifier.- Chlorination for disinfection in CCT. (if Required)- Disposal of treated water for end use.- Sludge recycling, digestion & disposal by using Filter Press or Sludge Drying Beds.The process usually does not require any primary settling and sewage after equalization directly goes to the aeration tank. However, in case of higher loadings, primary settling or grit chamber may be required. Elimination of primary settling reduces the initial cost, and also the sludge after extended aeration and secondary settling, is relatively more stabilized.
