Denderleeuw industrial WWTP - Phase 2 view Blue Foot Membranes

• Wastewater originating from animal waste and carcasses, high in FOGs and Nitrogen
• Start up of Phase 2: October 2019
• Amount of IPC^® membrane modules: 8 Triple Deck Modules

Project Background:

The modular approach of the IPC^® modules in Phase 1 led to a plant design with double-deck modules to expand in the same footprint to add an additional module layer on top to increase the capacity with an additional 40%.

In Phase 2, 8 double decks IPC^® membrane modules were modified to 8 triple decks by adding 8 additional modules on top of the exiting membrane towers. The tank size is only 1.6 m x 6 m and 4.5 m high and has a tank surface area of 9.6 m². This expansion delivered a very high capacity per footprint and a low specific aeration demand:

• Capacity/footprint: 13.3 m³ permeate/m² module footprint
• Specific Aeration Demand per hour and per permeate volume produced, SAD_p = 7 Nm³ Air scour/h.m³ permeate
• By this approach the capacity was increased to > 1 MLD.
