Features
♦New curtain style structure
♦Simple structure, easy maintenance, avoided the gather in membrane root of fiber, hair and sludge
♦Patented spinning technology, special support structure, solved the broken-silk problem
♦Good hydrophilicity, more stable operating flux
♦High filtration accuracy, not easy to be pollution clogging , good permeate quality
Hydrophilic and moisturizing membrane
Reinforced composite PVDF membrane makes use of hydrophilic modified PVDF uncooked materials, the membrane has properly hydrophilicity, and no hydrophilic therapy is wished in the site. However, if the diaphragm is now not put into use straight away after it is installed, or it desires to be parked for a positive duration of time all through use, please make certain that the diaphragm is immersed in water or it is usually in a moist condition.
Maintenance of membrane flux and membrane cleaning
Diaphragm aeration device development the usage of perforated aeration, aeration of bubbles and water flow, so that the movie full of jitter, to reap self-cleaning of the membrane. Using the intermittent operation mode, the self-priming pump can suck for 10 to 12 minutes and quit for two to three minutes, which can successfully forestall the clogging of the membrane holes and make sure long-term and secure operation of the membrane separation. When used for the first time, the microbiological subculture of the biochemical pool achieves precise activity, and the membrane is solely put into operation when the viscosity is small.
