High‑frequency membrane cleaning, difficult disassembly & assembly, and persistently high labor costs? These common headaches for water‑treatment professionals now have a solution.
Anyone who has done membrane cleaning knows the real trouble is not the cleaning itself, but the troublesome work before and after cleaning. You have to tighten every single screw on the membrane housing end cap and align sealing parts repeatedly. Disassembly and reassembly take more time than membrane cleaning. For heavily fouled membranes, cleaning may be required several times a week, and most labor hours are consumed on fitting and removal.
Strong corrosion from cleaning chemicals makes matters worse. Conventional membrane housings suffer liner aging and sealing failure after long‑term use. Leakage forces production shutdown for part replacement, pushing maintenance costs sharply higher.
The Chengda‑series 8‑inch FRP membrane housings for membrane cleaning under the Winder brand fully address all these pain points.
???? Quick‑Open Design: Say Goodbye to "Screw‑Tightening"
Anyone who performs membrane cleaning knows how annoying it is to disassemble and reassemble end caps on traditional membrane housings. Optimized for frequent mounting‑demounting scenarios, the Chengda series features a quick‑open end‑cap structure for simple, fast opening and closing.
Efficiency improves immediately. Within the same cleaning time, you can process two batches instead of one. The saved working hours and labor costs bring real economic benefits.
???? Heavy‑Duty Corrosion Resistance: Resist Damage from Acid‑Alkali Chemicals
Membrane cleaning heavily relies on highly corrosive agents such as acids, alkalis and oxidants. Made of high‑performance FRP (fiberglass‑reinforced plastic), the Chengda series delivers outstanding corrosion resistance:
✅ Working pH range: 3‑11, compatible with both acid and alkaline fluids
✅ Temperature range: -10°C ~ 66°C, stable under hot and cold conditions
It works reliably for acid cleaning for scale removal and alkaline cleaning for organic‑matter removal.
????️ Premium Quality Backed by ISO9001 & ISO14001 Dual Certifications
For pressure vessels, quality and environmental‑protection performance are equally important. Manufactured in strict accordance with international standards, the Chengda series has obtained ISO9001 Quality Management System Certification and ISO14001 Environmental Management System Certification. Key technical parameters:
???? Design pressure: 300 PSI, suitable for common cleaning working conditions
???? Burst pressure: 4 times design pressure, providing sufficient safety margin
???? Passed 120 000‑cycle fatigue test to simulate long‑term repeated pressurization, proving excellent durability.
Safe to operate, eco‑friendly and easy for customer acceptance checks.
???? Competitors are adopting quick‑open solutions — why wait?
Quick disassembly‑assembly has become a key technical trend for membrane housings. From quick‑fit housings for household RO membranes to lightweight new‑composite‑material housings, the market is pursuing more efficient and labor‑saving solutions.
The Chengda series is Winder brand’s robust answer to this market demand.
✅ Quick‑open structure: Get rid of complicated work and double your efficiency
✅ Corrosion resistance: Tolerate acids & alkalis for longer service life
✅ Reliable quality: Dual ISO certifications for worry‑free operation
Membrane cleaning can really be much easier.
