Transfluid Membrane Bioreactor (MBR) Systems combine the absolute precision of membrane separation with conventional biological wastewater treatment. By replacing traditional secondary clarifiers and gravity settling tanks with submerged microfiltration or ultrafiltration membrane modules, Transfluid MBR technology delivers a major leap in wastewater purification.

In an MBR system, high-density submerged cassettes are placed directly within an aerated biological tank filled with mixed liquor (activated sludge). As clean permeate water is drawn through the porous support structure by low-pressure suction, biomass, suspended solids, and bacteria are completely blocked at the membrane surface. The result is crystal-clear effluent water ready for direct reuse or sensitive environmental discharge, all within a fraction of the land footprint required by conventional plants.

Key Technical Features

• Submerged Cassette Design: Modular, high-density membrane cassettes are designed to fit directly into aerated biological tanks. This eliminates the need for massive secondary settling clarifiers, reducing the plant footprint by up to 50%.

• Microscopic Pore Precision ($0.04 - 0.4\ \mu\text{m}$): Engineered with a specialized microscopic surface layer that keeps Mixed Liquor Suspended Solids (MLSS) completely isolated. It reliably acts as a absolute barrier against biomass, Extracellular Polymeric Substances (EPS), and suspended organic structures.

• Integrated Air Scouring System: Built-in fine and coarse bubble aeration manifolds at the base of the cassette continuously scour the membrane surface. This dual-action aeration provides vital oxygen to the biological culture while keeping the membrane clean from foulant layers.

• High MLSS Operating Limits: Unlike standard clarifiers that fail at high solids concentrations, Transfluid MBR membranes operate flawlessly in high-biomass environments ($8,000$ to $12,000\text{ mg/L}$ MLSS), drastically improving the organic degradation rate (BOD/COD removal).

• Rugged Chemical and Mechanical Build: Constructed from high-strength hydrophilic polymers that resist compaction, tolerate intensive chemical cleaning cycles (CIP), and deliver an exceptionally long service life in harsh industrial matrices.

• Zero Liquid Discharge (ZLD) Pre-Treatment: Acts as the perfect, high-clarity feed system for downstream Reverse Osmosis (RO) membranes by minimizing the Silt Density Index (SDI) of the treated effluent.

Standard Scope of Supply

Every Transfluid MBR package is customized to meet your specific biological loading requirements:

1. Premium MBR Membrane Cassettes with integrated permeate manifolds and air-scour headers.
