Overview
The MBR processes used in sequence are as follows:
- primary treatment using fine screening (2mm perforated plate drum screen)
- biological nutrient removal including anoxic (denitrification) zone and aerobic (nitrification) zone with dissolved oxygen control
- membrane operating system (MOS) for filtration
Key advantages of an MBR wastewater treatment package plant are:
- High-quality effluent, with very low suspended solids and strong removal of bacteria and pathogens.
- Small footprint, because the membrane unit replaces a large secondary clarifier, making it suitable for tight sites and modular package plants.
- Better reuse potential, since the treated water can often be used for irrigation, toilet flushing, or industrial applications.
- Strong and stable treatment performance, because the membranes retain biomass and allow high mixed liquor concentrations.
- Easier expansion and packaging, since decentralized MBR systems are often built in modular, pre-engineered units that deploy quickly.
- Lower sludge production than many conventional systems, which can reduce sludge handling costs.
- For a package plant specifically, the biggest practical benefits are compactness, fast deployment, and consistently high effluent quality
