The Core Advantage: Reinforced PVDF (R-PVDF) Technology
Traditional unreinforced hollow fiber membranes frequently suffer from structural failure, fibre snapping, and rapid fouling under high Mixed Liquor Suspended Solids (MLSS) conditions. Hollowbrane addresses this critical vulnerability through its proprietary Reinforced PVDF (R-PVDF) architecture.
By braiding an inner structural core coated with a high-porosity PVDF polymeric skin, Hollowbrane R-PVDF membranes deliver:
- Zero Fibre Breakage: High tensile strength prevents snapping caused by heavy aeration cycles and coarse suspended solids.
- Extreme Chemical Tolerance: Resistance to aggressive pH regimes (pH 2–10) enables intense Chemically Enhanced Backwash (CEB) and Clean-in-Place (CIP) regimes without structural degradation.
- Anti-Fouling Surface Chemistry: Optimized pore size distributions (0.01 to 0.03 micron) ensure stable flux rates (LMH) and high mechanical recovery over long operational lifespans exceeding 5 years.

The 5-Stage Packaged Containerized MBR Systems Treatment Sequence
- Stage 1: Inlet Screening & Equalization:Raw wastewater passes through an integrated 100-micron automatic fine screen to capture grit, hair, and coarse debris, protecting downstream membranes and biological pumps from clogging.
- Stage 2: Anoxic & Aerobic Biological Treatment:Anoxic zones promote denitrification, while fine-bubble aeration diffusers supply oxygen to aerobic bacteria to rapidly degrade dissolved organics (BOD/COD) and oxidize ammonia to nitrate.
- Stage 3: Submerged R-PVDF Membrane Filtration:The mixed liquor suspended solids (MLSS) enter the membrane chamber. Vacuum pumps pull clarified water through the high-tensile R-PVDF hollow fiber pores, leaving bacteria, suspended solids, and micro-pollutants behind.
- Stage 4: Automated Backwash & CEB Skid:To prevent surface fouling and maintain high flux rates, the system executes periodic hydraulic backwashing and PLC-controlled Chemically Enhanced Backwash (CEB) or Clean-in-Place (CIP) cycles using diluted sodium hypochlorite or citric acid.
- Stage 5: High-Purity Permeate Disinfection:Permeate is passed through an inline UV disinfection assembly to ensure complete pathogen control, producing high-purity water ready for cooling towers, flush tanks, or landscape irrigation.

Dissolved Air Flotation (DAF) Machines
Hollowbrane Dissolved Air Flotation (DAF) units eliminate micro-suspended solids, fats, oils, greases (FOG), and colloidal particles by injecting microbubbles into the wastewater stream. The microbubbles attach to suspended contaminants, floating them to the surface where an automated skimming mechanism removes the sludge layer. DAF systems serve as an essential primary protection step ahead of biological MBRs in high-FOG industries.
Electrodeionization (EDI) Systems
For high-tech industries requiring continuous ultra-pure water (UPW) without chemical handling, Hollowbrane supplies advanced Electrodeionization (EDI) systems. Operating downstream of a two-pass RO system (pre-treated by Hollowbrane UF modules), EDI utilizes DC electrical current, ion-exchange membranes, and resin media to continuously deionize water without acid or caustic regeneration cycles.

Frequently Asked Questions (FAQ)
What makes Reinforced PVDF (R-PVDF) membranes superior to standard hollow fiber membranes?
Standard unreinforced hollow fiber membranes are prone to fiber breakage under high aeration turbulence and heavy solids loads (MLSS). Hollowbrane’s R-PVDF membranes feature a high-tensile inner braided core wrapped in a porous PVDF skin. This structural reinforcement eliminates fiber snapping, tolerates extreme chemical cleaning (pH 2–10), and significantly extends module operational lifespans beyond 5 years.
What are Packaged Containerized MBR Systems, and where are they best deployed?
Packaged Containerized MBR Systems are prefabricated, plug-and-play wastewater treatment plants housed inside weatherproof, transportable containers or skids. They integrate biological oxidation and MBR membrane filtration into a compact footprint. They are ideal for decentralized applications such as commercial complexes, hotels, construction camps, remote mining sites, and industrial facilities requiring quick installation with minimal civil construction.
Can Hollowbrane R-PVDF MBR modules be used as retrofits for existing MBR plants?
Yes. Hollowbrane membrane cassettes and modules are designed to serve as 1:1 drop-in direct replacements for aging or failing MBR modules from major global manufacturers (e.g., ZeeWeed 500 series). They fit directly into existing steel cassette frames and piping manifolds without requiring structural redesign.
What is the typical quality of treated effluent from a Hollowbrane MBR STP/ETP?
Hollowbrane MBR systems deliver crystal-clear, highly polished effluent with Biochemical Oxygen Demand (BOD) < 10 mg/L (often < 0.5 mg/L), Total Suspended Solids (TSS) < 5 mg/L, and turbidity < 0.2 NTU. The treated water complies with stringent environmental discharge standards and can be directly reused for cooling towers, toilet flushing, construction, or landscape irrigation.
What is the difference between Ultrafiltration (UF) and Membrane Bioreactor (MBR) technology?
- Ultrafiltration (UF): A purely physical separation process used primarily as tertiary polishing for clarified water or as pre-treatment ahead of Reverse Osmosis (RO) to remove suspended solids, bacteria, and turbidity.
- Membrane Bioreactor (MBR): Combines biological wastewater treatment (activated sludge/aerobic digestion) directly with membrane filtration, replacing secondary clarifiers and sand/carbon filters in a single compact process.
How are membrane fouling and scaling managed in Hollowbrane systems?
Hollowbrane MBR and UF systems feature automated PLC/HMI-controlled cleaning cycles. Routine maintenance includes continuous air scouring (aeration), periodic hydraulic backwashing, and automated Chemically Enhanced Backwash (CEB) or Clean-in-Place (CIP) using diluted sodium hypochlorite (oxidant) or citric acid (scale remover).
What production capacities can Hollowbrane Membrane Technologies support?
Hollowbrane maintains a monthly manufacturing capacity of 20,000 m² of R-PVDF MBR membranes and 10,000 m² of polymeric Ultrafiltration (UF) membranes, supporting projects ranging from small decentralized 5 KLD units to multi-megaliter municipal and industrial installations.
