These MBR systems combine active sludge biological wastewater treatment with a solid-liquid separation process using a physical membrane.
MBR systems use low-pressure microfiltration or ultrafiltration membranes, thereby eliminating the need for an additional clarification and tertiary treatment stage. MBRs produce very high-quality water suitable for direct reuse or as a source of very high-quality water for reverse osmosis filtration systems.
Applications
Industrial and urban wastewater treatment
Treatment capacity: 4 to 2,000 population equivalent
The effluent obtained from an MBR unit is suitable for reuse for any of the uses set forth in Royal Decree 1620/2007 on the reuse of treated water
Urban uses: watering gardens, flushing toilets, watering communal areas, hosing down streets, washing vehicles, etc.
Agricultural uses: irrigating crops, washing products for human consumption, watering pastures, etc.
Industrial uses: cleaning water, industrial process water, cooling towers and evaporation condensers.
Recreational uses: watering golf courses, filling ponds and water masses not accessible to the public.
Environmental uses: topping up aquifers, irrigating green areas, forestry, etc.
Advantages
Compact modular systems – Reduced facility surface area – High treatment yields – Ideal for difficult-to-treat industrial wastewater – Low sludge production – High stability in the face of load and flow variations – Remote alarm, control and monitoring systems – Easily adaptable to existing plants and/or tanks (conversion of septic tanks)
‘ECO’ energy saving system for reduced activity periods
