Automatic ultrafiltration unit
Bran+Luebbe
Filter unit for Bran+Luebbe On-line Monitors
For municipal and industrial waste water treatment plants
All particles with a molecular weight >20,000 are retained by the membrane filter. When the filter surface becomes blocked, operation switches to the second filter tube and the first one is cleaned. Filter changeover and cleaning can be manual or automatic, depending on the model.
Ultrafiltration Operation
A sample pump (side or immersed type) provides a continuous stream of sample at 8 m3/h through one filter tube while the other tube is in stand-by. The filter tubes operate under virtually zero pressure conditions. The filtrate pump has two functions: It determines the filtrate volume and supplies the Monitor with the necessary sample pressure.
