Product Introduction：
Naino ROB series membrane elements adopt a unique parallel flow channel structure, no dead angle in the structure, with excellent anti-fouling ability and cleanability, reduce the number of chemical cleaning, and have a high recovery rate. At the same time, it also has the advantages of low pressure, high flux and high desalination rate of traditional polyamide composite membranes.
It is suitable for micro-polluted source water with high COD and SS, and can simplify the pretreatment process under some conditions, such as: municipal reclaimed water reuse, industrial wastewater reuse, surface water treatment, landfill leachate treatment, etc.
