Evoqua Water Technologies Memcor CSII Ultrafiltration System

Evoqua Water Technologies has introduced an ultrafiltration system that allows users to design submerged membrane systems with low cost of ownership, according to the company.

The Memcor CSII Ultrafiltration System has fibres open to filtration at both ends. Double-ended filtration delivers a more efficient use of air, with the module able to operate at a 23% lower relative aeration rate. There are no changes to the ability of backwash to remove solids, and stability is assured during high-turbidity events.

The module design results in a reduction in the module footprint of over 50%, with plant footprint reduced by 30%. Higher design fluxes reduce the total number of modules needed for a given plant size. There is no change to the module diameter, ensuring no loss in solids handling ability.

The product has good performance in pressurised systems, with lower head loss saving on pumping energy by 7–20%. Upcoming projects can use the system at low risk, as it enables the use of largely established componentry, while an easy upgrade path is enabled for existing plant owners.
