KC-BW 8040 Series Brackish Water RO Membrane Elements for Industrial Water Treatment
KC-BW 8040 Series are brackish water reverse osmosis membrane elements developed for industrial and municipal water treatment systems requiring high salt rejection, stable permeate flow, and efficient operation. Based on aromatic polyamide technology, the series provides reliable desalination performance under low-pressure brackish water operating conditions.
The standard BW type is typically used for brackish water, surface water, groundwater, and tap water treatment with feed water TDS up to approximately 5,000 mg/L. FR, HF, and ZM options are available for fouling-prone water, higher flow requirements, and higher-rejection applications, with ZM models supporting more demanding salinity conditions.

FAQ
FAQ
Q1. What applications are KC-BW 8040 Series membranes typically used for?
They are widely used in large-capacity brackish water RO systems, municipal water treatment, industrial pure water production, reclaimed water reuse, and process water treatment projects.
Q2. How should I choose between BW, BW-FR, BW-HF, and BW-ZM types?
Standard BW is suitable for general brackish water treatment, BW-FR is used for more complex or fouling-prone feed water, BW-HF is selected for higher permeate flow, and BW-ZM is used when higher salt rejection is required.
Q3. What feed water is suitable for KC-BW 8040 Series?
The standard BW type is commonly used for feed water such as surface water, groundwater, tap water, and brackish water. FR or ZM types may be selected for more challenging feed water depending on system design.
Q4. Can KC-BW 8040 Series be used for wastewater reuse projects?
Yes. BW-FR models are especially suitable for reclaimed water, wastewater reuse, RO concentrate recovery, and other applications with more complex feed water conditions.
