MBR

In an effort to minimize the short and long-term environmental impact, industries across the globe are facing increasing challenges and costs related to wastewater management. As a result, most of the industrial facilities have built their own treatment plants, thus achieving regulatory compliance, avoiding the fees for sewer discharge, and reducing their water footprint by means of water reuse.

The MBR is essentially a high-efficient evolution of the conventional activated sludge process, where the clarifiers are replaced by the tubular UF modules. In this way, significant improvements are achieved: superior effluent quality, higher biodegradation rates, smaller footprint, less sludge production and reuse possibilities. All these features are essential for coping with the stringent discharge quality requirements and the economic benefits of water reuse faced by almost all the industrial sectors.

MBRs remove up to 99% of COD, compared to 90-95% in conventional activated sludge processes. The operation with higher MLSS concentration – even up to 30 g/L – results in minimum footprint requirements and decreased production of excess sludge. The filtrate produced by the membranes is free of solids (TSS < 1 mg/L) and turbidity (< 1 NTU), and presents SDI values lower than 3, optimum for further RO treatment if required.

These advancements in MBR technology make it a preferred choice for industrial wastewater treatment, offering both environmental and economic benefits.
