characteristic:
■ The microfiltration membrane module uses a PVDF reinforced membrane, which is resistant to fouling, easy to clean, and has a long service life.
■ The membrane modules are bundled and distributed, with reasonable spacing between membrane fibers, which can maintain filtration flux and reduce sludge clogging.
■ The membrane fibers at the bottom of the membrane module are encapsulated using proprietary technology, which avoids the problem of fiber breakage during the swinging process of the bottom membrane fibers.
■Suitable for the treatment of urban sewage, reclaimed water, industrial wastewater, landfill leachate, and other wastewater.
