Product Introduction：
Naino ROC series membrane elements use seawater desalination SW reverse osmosis diaphragm and high-pressure resistant assembly technology, which can withstand up to 90bar pressure impact and has strong stability. The membrane element adopts a unique parallel flow channel structure, which has excellent anti-fouling ability and cleaning resistance, and has good cleaning recovery performance.
It is suitable for high-salt and high-concentration organic wastewater with high COD and SS, simplifying the pretreatment process, such as seawater desalination, zero-discharge advanced treatment, high-salt wastewater treatment, landfill leachate and other fields.
