The OCRO membrane module subversively overcomes the requirement of the traditional roll-type reverse osmosis membrane for the inlet water quality. Restriction can greatly simplify the influent pretreatment process, and the average service life of the membrane is as long as 3-5 years.
The DTRO membrane module includes a pressure vessel, a hydraulic disc, and a diaphragm sandwiched between every two discs. This special structure forms an open flow channel between the valve flap and the diaphragm.
