KAIMI MEMBRANE experience:
Kaimi has taken many project of landfill leachate treatment in China. It’s a mature technology, use our tubular membrane as external membrane bioreactor and combine it with biochemical process. It can remove 80%~90% BOD, COD and SS.
Tubular MBR/External MBR : External MBR technology replaces the conventional secondary sedimentation tank by the method of activated sludge. The wastewater was pumped into membrane module and is filtered by membrane under pressure, the permeate was sent to water tank or be discharged, and the retained sludge and concentrate are sent to Bio-Reactor tank.
Advantages of high packing density membrane system for landfill leachate treatment:
High flux, is 6 to 10 times more than common submerged MBR
Membrane with strong antifouling property and high regeneration performance
Backwash is not required, only periodic chemical cleaning, CIP is easy and convenient
Reliable operation, service life can be up to 6 years
Single membrane can be replaced separately; membrane is unbreakable, not easy to clog and has long service life
No discharged concentrate, water recovery rate is up to 100%
Independent running, high degree of automation, low cost of labor
Highly integrated equipment, small footprint, strong resistance to impact
Easy to maintain, low maintenance cost
