The Berghof BioPulse MBR concept is an energy optimized process for reliable and economic treatment of medium strength wastewater. The BioPulse MBR concept is based on the same membrane as Berghof BioFlow, but it makes use of the unique feature of the HyMem 8mm PVDF LE (Low Energy) membrane: it can be backwashed. The membrane module array is similar to the Berghof BioFlow principle.

Activated sludge from the bioreactor is pumped, at an optimized flow rate, through the externally positioned tubular 8mm LE membranes. An integrated automatic backwashing program controls the backwash cycles and backwash time in order to ensure reliable operation under economic conditions.

Characteristic

• Reliable and economic
• Realiable and economic treatment of low and medium strength waste water
• Based on backwashable I8LE membrane (internal diameter 8 mm)
• Easy fouling control due to periodically backwashing
• Permeat flow control by permeat suction pump
• Maximum flexibility with variable speed pumps (1 - 2 m/s)
• Less membrane surface at peakflow
• High gross flux 45 - 60 l/m².h
• Low energy consumption 0.4 - 1.7 kWh/m³
• Suitable for containerized UF-systems
