Spanish company Fluytec has launched a new continuous ultrafiltration (c-UF) system with an incorporated, online cleaning system that can reduce ultrafilitration capital costs by up to 20%.
Fluytech said its new c-UF system cleans each ultrafiltration module individually while the rest of the system remains online.
 
It has, the company claims, has an innovative control system to ensure a constant product flow during backwash, flushing and rinsing, as well as during chemically enhanced cleanings. The arrangement eliminates the need for backwash pumps and tanks, blowers and transfer pumps, which reduces the system's capital cost.

Unlike the company's other, more traditional UF systems, which use outside-in UF membrane technology, the c-UF systems employ multibore PES membranes that operate with an inside-out flow path. But Fluytech said it can customize its c-UF systems for use with outside-in membranes if preferred by a customer.

The footprint of the skid-mounted 50 m3/h c-UF system is 7m2 which the company claims is up to 50% smaller than a conventional UF system. It also offers the system with integrated RO systems mounted on a common skid or container.
