                                      CASS process

            The genus CASS SBR sewage treatment process of sewage treatment unit series, is set in the SBRanaerobic biological selection zone of intermittent aeration aerobic biochemical treatment of Chi Qian. Into the flow sewage first into the biological selection area and aeration zone reflow mixed sludge, sewage into the aeration zone after mixing, under aerobic conditions, aerobic activated sludge and nitrifying bacteria oxidize organic pollutants in wastewater, nitrogen removal, carbon removal, achieve the purpose of phosphorus removal.

               The process characteristics of CASS

            one:the CASS process sequencing batch operation, on the water quality, water fluctuationadaptability and operation flexibility is bigger.

             two:into the flow of sewage first in the biological selector reactor front end and back flow from theaeration tank<, SPAN style="WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(51,51,51); FONT: 14px/22px arial; LETTER-SPACING: normal; BACKGROUND-COLOR: rgb(255,255,255); TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px" space="0| " right-pos="85|18" left-pos="199|18"> activated sludge mixed, promote the flocculating bacteria growth, improve the activity of the sludge, and inhibit the filamentous sludge bulking caused reproduction, while the release ofactive sludge in poly phosphate and complete denitrification process, the mixed liquid wastewaterentering the aeration pool for BOD5 aerobic oxidation and decomposition, denitrification andphosphorus absorption amount. CASS sewage treatment process of sludge settling performance is good. Can effectively prevent the sludge bulking, biochemical system more stable and reliable operation.

             there: short process flow, low investment in Civil Engineering (without primary sedimentation tank, two sedimentation tank and the larger the return sludge pumping station), high degree of automation,compact layout, small land occupation, convenient installment construction and expansion.

             

           

           

           

           

           

           

           

                    The scope of application

             CASS process is suitable for a wide range, suitable for construction by stages;

              Can be used in large, medium and small wastewater treatment engineering
