[Case Studies] [Introductory
conventional activated sludge processes, separation of treated
water from the sludge is mainly achieved by sedimentation
in secondary clarification tank. This requires a considerable
amount of space and capital cost, and separation efficiency
membrane to replace the secondary clarification tank, suspended
solids can be completely removed from treated water, resulting
in a high effluent quality. It not only concentrates slow-growing
bacteria, but also retains large molecular organic compounds
in reactor, thereby increasing contact time with the sludge.
Thus removal rate of COD, BOD, nitrogen and phosphorus will
be greatly increased.
