er treatment thereby replacing, and in some cases supplementing, the solids separation function of secondary clarification and effluent filtration, resulting the possibility to eliminate the secondary clarification and operate at higher MLSS concentration. In summary, the MBR system is the combination of traditional Activated Sludge Treatment with the membrane technology. The design criteri..
ed Sludge Treatment with the membrane technology. The design criteria of the system shall be base according to the traditional way of Activated Sludge Treatment principle. However, on top of that, the MBR modules are immersed and located in the air blow tank/ aeration basin (biological reactor tank), the clear water is pumped(sucked) out from the MBR modules. This shall possibly eliminate the needs of secondary. 1 Nos of pcs. of membrane are connected parallel through the header to form a frame. Connected frame network will form a Membrane Unit. 2 It is then connected the suction side of a permeate pump, the membranes are subjected to a slight negative pressure of 10 to 30 kPa (1.5 to 4.5 psi). 3 In an “outside-in†process operation, water is drawn from the mixed liquor through the membrane module and into the hollow fiber, further enhanced by suction effect of pump. From there, the treated water is drawn through the header and out through the discharge system. 4 On a continuo.
