Membrane bioreactor is a kind of new type sewage treatment technique which combine high efficient membrane separation technique and activated sludge manner, it inherit membrane separation technique and biochemical treatment technique feature and intensify biochemical treatment effect, it can used in high organic content municipal or industrial sewage treatment. 

MBR system use hollow fiber membrane to make solid-liquid separation. The NL series immersed hollow fiber membrane is special developed membrane module. It has higher filtering efficiency, it can effective remove bacteria、suspended particles and impurity, thus get the superior filtering water. In additional, due to each unit membrane module filtering area big, small membrane installation occupy volume, decrease reactor volume and occupy area.

Our company based on the SBR techniques ( sequencing batch reactor) developed a new kind matched equipment which can make up SBR many deficient; which can widely apply to all kind of sewage treatment plant.. the package sewage treatment plant principle is a kind of biochemical treatment which combine activated sludge microbiological method and new biological membrane manner. In treatment process, large bacteria and bacteria membrane update, adopt biological carrier, improve the contact efficiency of micro- organism and pollutant matter in sewage; the whole treatment equipment produce anaerobic-anoxia- oxidation three kind of environment take turns function, improve purified water ability of different kind of microbial population, intensify organism removal and nitrogen and phosphorus removal function.
