Koch Membrane Systems launches PULSION MBR at WEFTEC 2015

PULSION MBR is claimed to lower aeration energy consumption by 40%, reduce system footprint by 25%, and simplify system design and operation.

“PULSION MBR represents the next generation of MBR technology built on the same robust membrane utilised in PURON MBR systems all over the world," reports Manny Singh, Senior Vice President of Technology for KMS.

"The energy efficiency and reduced footprint of our PULSION MBR gives us the opportunity to offer the proven performance of the PURON single header design, reinforced PVDF membrane, and central aeration to new and existing applications for a comparable cost of ownership to conventional wastewater plants.”

Energy efficient

PULSION MBR pulses a large bubble through a chambered fibre bundle creating a highly efficient pumping action resulting in lower air and aeration energy requirements than traditional air scour methods. Improved recirculation of mixed liquor within the membrane module results in lowered air requirements, and also boosts achievable fluxes.

Coupling greater productivity with an increase in packing density allows the overall system footprint to be significantly reduced. Operating with a continuous supply of air eliminates the need for air cycle valves.

KMS reports that a reduced air flow rate applied to the membranes on a continuous basis, instead of high air flows applied cyclically, reduces the size of the air delivery equipment by 50%.
