Benefits:
The STRO series membrane elements are high-pressure concentrated membranes that are encapsulated in fiberglass wrapping and can withstand pressure shocks of up to 90 bar. It is suitable for high-salt and high-concentration organic wastewater, simplifying the pretreatment process. Moreover, the system operation mode is flexible, and the primary and secondary treatment forms can be selected according to the requirements, and the treated water purification can meet the national discharge standards or reclaimed water reuse standards. The treatment objects involve landfill leachate, steel, medicine, chemical and other difficult wastewater.
