Navi Mumbai (NMMC) Wastewater treatment plant view Blue Foot Membranes

• Case study IPC^® Bioreactor – NMMC
• 2 bar Back Pulsable Flat sheet
• Start up: November 2016
• Number of IPC^® membrane modules: 1 IPC^®25 Double Deck Module

Project Background

Navi Mumbai Municipal Corporation (NMMC) has six operational sewage treatment plants of different capacities. These plants treat the domestic sewage generated within the city using SBR process. The objective was to upgrade the existing level of treatment. This by using the tertiary treated sewage with ultrafiltration to improve the water quality as per the latest CPCB norms.

To achieve this objective a full-fledged, completely automated 100 KLD Indion MBR system was installed with IPC^® membrane modules for testing. The operational net flux is between 36 and 42 LMH and this is created with a very low aeration volume compared to other competitive products.

Other advantages that are recorded:

• High capacity footprint = 11 m³/h.m²
• Very low Specific Aeration Demand per hour = 8 Nm³ air/m³ permeate
• Lowest cost per unit treated water (less than €0,012/m³) for raw sewage
• Decreased cleaning frequency caused by effective backwash.
