Overview
UNIBRANETM is a proprietary Membrane Bio Reactor (MBR) system developed by Keppel Seghers for wastewater treatment. It combines biological degradation with membrane filtration to produce high-quality effluent suitable for reuse.

Principle
The system offers superior effluent quality, high system availability, and low operational costs. It features a compact design and can be configured with either submerged or external membranes, facilitating advanced biological and phosphorus removal while generating less excess sludge compared to conventional systems.

Applications
UNIBRANETM is suitable for both industrial and municipal wastewater treatment. Its modular design allows for phased construction and adaptability to various sizes and flow rates.

Process Description
The submerged system uses flat sheet membranes immersed in the process tank, directly contacting the mixed liquor. Air is introduced below the membranes to maintain cleanliness and provide oxygen for biological processes. The system is highly automated, ensuring ease of operation and low maintenance costs.

External System
An external version is available for lower capacities or higher temperature conditions. It is suitable for operations with high dry solids content.

Containerised Units
UNIBRANETM can be delivered as a containerised unit, offering advantages such as no on-site construction and short delivery times.
