Product Overview
Coalescer Filter is one of our star products for oil‑gas industry, and reverse osmosis membrane element LF‑BW‑8040FR‑PRO anti‑fouling RO‑membrane belongs to Water Filter Element series. It adopts special hydrophilic‑modified polyamide surface‑treatment plus 34‑mil wide‑flow‑channel design, effectively reduce organic‑and‑colloid‑pollutant adhering‑tendency. Mainly oriented to industrial‑waste‑water‑reuse and recycling‑water‑treatment working‑condition under high‑COD feed‑water‑environment.

Industrial Waste‑Water Reuse Application Scenarios
LF‑BW‑8040FR‑PRO reverse osmosis membrane element targets harsh high‑pollution feed‑water working‑condition. In steel‑plant circulating‑cooling‑water reuse‑project, raw‑water contains oil‑trace, colloid and microorganism; wide‑spacer flow‑channel reduce pollutant‑deposition risk. Chemical‑plant secondary‑waste‑water recycling‑system also adopts this FR‑series membrane‑element. Must configure complete‑pre‑treatment: UF‑ultrafiltration + security‑filter‑cartridge as front‑protection, High Flow Filter Cartridge can be selected as security‑filter consumable. Not suitable for seawater‑desalination, seawater‑scenario choose SW‑series seawater‑membrane‑element. For reference of filter‑consumable‑production‑QC‑standard you can check Interchangeable Hydraulic Filter Elements quality‑management‑system.
Core Product Advantages
Special hydrophilic‑modified membrane‑surface greatly inhibit organic‑colloid adsorption, prolong chemical‑cleaning cycle and cut‑down site‑maintenance‑cost. 34‑mil wide feed‑spacer reduces block‑risk under high‑pollution‑water‑flow. Wider pH‑tolerance‑range for chemical‑cleaning, adapt frequent acid‑alkali‑cleaning operation of waste‑water‑project. Stable high salt‑rejection‑rate for recycling‑water‑desalination‑process. Standard 8040‑size fits common 8‑inch pressure‑vessel for direct‑replacement. Each membrane‑element will pass performance‑simulation‑test before factory‑delivery.

FAQ
Q1：What is main‑difference between FR‑PRO anti‑fouling‑membrane and ordinary BW‑series RO‑membrane?
A1：FR‑PRO adopts hydrophilic‑modified surface plus 34‑mil wide‑flow‑channel, more‑resist organic‑colloid‑pollution, suitable for waste‑water‑reuse high‑COD feed‑water; ordinary BW‑series fit clean brackish‑water source.
Q2：What pre‑treatment is strongly suggested for FR‑PRO anti‑fouling RO‑membrane?
A2：Ultrafiltration UF pretreatment + security‑filter is highly recommended, reduce colloid and organic‑matter load entering RO system.
Q3：What is allowable pH range during chemical cleaning?
A3：Chemical‑cleaning pH range 1‑13, it can bear frequent acid‑alkali cleaning cycles for industrial waste‑water project.
Q4：Can BW‑8040FR‑PRO be used for drinking‑water production with clean surface‑water?
A4：Technically installable, but for clean source‑water ordinary BW‑PRO model has better cost‑performance.
Q5：Do you supply smaller‑size 4040 anti‑fouling RO‑membrane for pilot test?
A5：Yes, BW‑4040FR is available for small‑scale pilot‑plant trial‑run project.
