Reinforced PVDF MBR Membranes for Textile Wastewater Recycling
Followed by primary and secondary treatment, remove dye color, reduce COD and BOD levels by 95% and comply with wastewater discharge regulations. Built for Zero Liquid Discharge (ZLD) systems with a 0.03 micron filtration layer.
Textile Effluent Challenges
Textile dyeing and washing processes produce wastewater with high organic loads, chemicals and intense color. Standard treatment systems often struggle to meet strict discharge limits.
High Color & Dye Content
Reactive dyes dissolve easily in water and do not settle out in standard biological systems. This makes color removal difficult without advanced filtration.
High COD & BOD Levels
Sizing agents, starches and processing chemicals create high COD and BOD levels, overloading standard wastewater systems.
Chemical Pollutants
Surfactants, microplastics and heavy metals damage the bacteria in standard activated sludge systems and block downstream filters.
Government Compliance & Water Costs
Pollution control boards require Zero Liquid Discharge (ZLD). Recycled water helps mills avoid rising fresh water costs.
Why Gravity Clarifiers Fail in Textile Effluent Plants
Conventional ETPs use gravity to settle biological sludge in clarifiers. However, textile chemicals cause sludge bulking, preventing proper settling. This washes biological solids out of the tank and damages downstream Reverse Osmosis (RO) membranes.
Poor Sludge Settling
Chemical surfactants prevent sludge from settling, resulting in cloudy effluent water.
Large Space Required
Gravity clarifiers, sand filters and carbon filters take up significant factory land.
The MBR System
MBR replaces clarifiers and sand-carbon filters with a physical reinforced PVDF membrane barrier (0.03 micron). It filters out all suspended solids and allows operation at high biomass density (MLSS).

Key Benefits of MBR for Textile Mills
Technical advantages designed to reduce operating costs and improve water recycling rates.
Clear Filtered Water
Water turbidity stays below 0.2 NTU and Silt Density Index (SDI) under 3. This protects downstream RO membranes from fouling and extends their life.
High Biomass Density (MLSS)
Operates at sludge concentrations of 8,000 to 12,000 mg/L. This helps digest heavy organic loads and buffers incoming pollution shocks.
Saves Up to 60% Space
By eliminating clarifier tanks and sand filters, the system requires much less land area, saving space in your factory.
Solids & Dye Separation
Retains biological solids, microplastics and large dye molecules, preventing them from escaping into reuse lines.
Lower Sludge Production
Operating with a high sludge retention time (SRT) reduces excess sludge generation by 30% to 50%, lowering disposal costs.
Low Operating Costs (OPEX)
Air scouring nozzles use less energy, keeping electricity consumption below 1.1 kWh per cubic meter (kL) of recycled water.
Tailored for Every Textile Segment
Tested and validated under diverse manufacturing conditions.
Denim Processing
Removes heavy indigo dyes, pumice powder and microfibers for washing reuse loops.
Cotton & Yarn Dyeing
Tackles high salt effluents, hydrolysed dyes and complex chemical sizing agents.
Printing & Finishing
Handles pigments, gums and high molecular solvents, producing clear RO feed.
Synthetic & Blends
Filters microplastics, spinning oils and chemical surfactants with absolute retention.

Why Braid-Reinforced PVDF is Necessary
Standard unreinforced membranes can break due to mechanical stress from continuous air bubbles. If a fiber snaps, untreated sludge leaks into the clean water line, clogging downstream RO systems.
Neya Memveins hollow fibers have a strong inner braid covered by the PVDF filtration layer. This design handles up to 300 Newtons of pulling force, preventing snapping.
Good Water Flux
Even pore distribution allows high water flow rates at low suction pressure.
Chlorine Resistant
Resists chemical washes with chlorine and citric acid to easily clean off organic build-up.

Real-World Case Study
Read how a leading denim dyeing park in Ahmedabad retrofitted their conventional ETP with Neya Memveins MBR Modules.
Case Study: 800 KL Denim ETP Retrofit
A denim dye park suffered frequent biomass washouts in their gravity clarifiers due to starch sizing shocks and blue indigo dye toxicity. Permeate quality fluctuated and downstream RO membranes fouled every 4 weeks, resulting in massive operational downtime.
Retrofitted secondary clarifiers into a membrane tank housing **Neya Memveins MBR modules** sized for 800 KL capacity. Operating MLSS was increased from 3,000 mg/L to 10,000 mg/L and sand-carbon filtration was completely bypassed.
- Permeate turbidity fell below 0.15 NTU consistently.
- Downstream RO membrane lifespan extended from 4 weeks to 18+ months.
- Water recovery rate stabilized at 96% for direct reuse in printing.
