Using Membrane Coagulation Reactor For Water Treatment

Membrance Coagulation Reactor consists of membrane separation and coagulation process .This process is a combination process that has advantage of short hydraulic retention time,easy usage and management,steady and good treatment effect. Tianjin University has made some tests and research on MCR in small-scale test system, pilot-scale system and project case since 2000 and has a good effect. This study was based on the MCR-300, after testing the effluent of CODMn,UV254,UV410 and turbidity, We found that the effluent quality meet the National Standard on Domestic Drinking Water Quality Standard(2001) .The result indicated that MCR-300 is a equipment for drinking water that has quite a few advantages on middle scale, intermission working, short time and also can supply healthy drinking water for far from the center and army..Another one is MCR-15,a new test equipment used to treat high fluorin water, based on the principle of MCR with small-scale system.The two month test result showed that it had good effect on fluorin remove.We add some flocculation to raw water with fluorin 3-5mg/L at proper pH, the effluent fluorinin can <1mg/L, meet the National Standard on Domestic Drinking Water Quality Standard(2001).In order to use the results of test to project case, the writer demonstrates the feasibility of MCR, used to large-scale and small-scale water treatment system.On basis of this conception, we compare some project case and processes,then give the basic useful condition, which is valuable for reference in this process to be used in future.
