MARAPUR--a new process combination for the optimization of MBR

Area of Science:

• Environmental Engineering
• Water Treatment Technologies

Background:

• Membrane bioreactors (MBR) are advanced systems for wastewater treatment.
• Effective prevention of membrane fouling is crucial for MBR operational reliability.

Purpose of the Study:

• To introduce the MARAPUR concept, a novel MBR-based wastewater treatment process.
• To highlight the advantages of the MARAPUR concept, including enhanced filtration and reduced chemical usage.

Main Methods:

• The MARAPUR concept employs ultrafiltration of activated sludge using pressure-driven hollow fiber membranes.
• Vertical membrane modules are integrated into a compact MEGAMODUL system.
• Permeate extraction is performed in a cross-flow configuration, supported by rinsing aeration.
• Wastewater fine sieving with a 0.25 mm mesh size is implemented.

Main Results:

• The process achieves high filtration performance.
• Excellent operational reliability is demonstrated.
• A reduced demand for cleaning chemicals is observed.
• Fine sieving effectively prevents membrane clogging from hair and fibers.

Conclusions:

• The MARAPUR concept offers a robust and efficient solution for biological wastewater treatment.
• The integration of fine sieving significantly enhances membrane longevity and process stability.
• This approach leads to improved overall wastewater treatment efficacy and sustainability.
