Delivers clear water with ultra-low contaminants (typically TSS < 2 mg/L, COD ≤ 10 ppm, BOD ≤ 5 ppm). Features 0.04–0.1 μm pore size, 500× higher filtration precision than traditional sand filtration, effectively removing bacteria, viruses, colloids and suspended solids.d

Chlorine Tolerance: The Cleaning Advantage Nobody Talks About
Here's the dirty secret of wastewater treatment: biological fouling is inevitable. The question isn't whether your membrane will foul - it's how well it survives the cleaning. Chlorine is the most cost-effective sanitizer available, but it destroys unprotected membrane polymers. Our PVDF formulation? It shrugs off chlorine concentrations that would embrittle and crack lesser materials. This means you can run aggressive sanitation cycles whenever biofilm builds up, without the slow degradation that shortens membrane life. In hot climates where bacterial growth accelerates, this chlorine tolerance can extend membrane service life by 2–3×. That's not a minor footnote - that's the difference between replacing membranes every 2 years and every 7.

Hydrophilic Modification: Permanent, Not Coated
Many manufacturers apply a hydrophilic coating to their PVDF membranes. It works great - for about six months. Then the coating washes away and the intrinsic hydrophobicity returns, fouling accelerates, and flux drops off a cliff. Our approach is fundamentally different: we chemically graft hydrophilic functional groups directly into the PVDF molecular chain during the spinning process. It's not a coating; it's part of the material itself. The result is a membrane that stays wet, stays clean, and maintains stable flux for the entire service life. No recoating. No surprise degradation. Just consistent performance year after year.

1. Electroplating & Metal Finishing - Surviving the Chemical Cocktail
Electroplating wastewater is among the most aggressive industrial effluents: heavy metals, complexing agents, extreme pH swings, and high conductivity. Our PVDF MBR membranes operate reliably in this hostile environment, providing the chemical resistance needed for repeated cleaning cycles. The membrane barrier captures suspended metal hydroxides and fine particulates while the biological process degrades complexed organic additives. For metal finishing operations facing tightening discharge limits, PVDF MBR delivers consistent industrial effluent treatment performance where other membrane materials simply fail.

2. Food Processing - High-Load, High-Temperature Stability
A meat processing plant generates wastewater with COD levels exceeding 10,000 mg/L, elevated temperatures from wash-down cycles, and intermittent fat and grease loading. Our PVDF MBR modules handle these fluctuations without missing a beat. The thermal stability keeps performance consistent even when hot water hits the membrane during cleaning, and the chemical resistance allows for aggressive degreasing protocols. The treated effluent meets discharge standards while the compact footprint fits within the tight confines of an existing plant layout.
