Ultrafiltration
Ultrafiltration (UF) is a process where water is filtered by a polymeric membrane with a very small pore size. Especially for difficult types of raw water, where the particle load fluctuates strongly with the seasons, ultrafiltration, with its clearly defined separation limit and its individual backflushing concepts, can really show its strengths. To achieve this, the process engineering is modular. This means that a single ultrafiltration unit can react flexibly to changes in the quantities required as well as to fluctuations in the composition of the raw water.
Ultrafiltration is characterised primarily by its higher performance when it comes to the retention of particles. In comparison to a sand or gravel filter system it has significantly better separation, in particular of ultrafine particulate pollutants.
The benefits of ultrafiltration at a glance:
- Removal of ultrafine particulates due to the low pore size of the ultrafiltration membrane
- Ultrafiltration serves as the ideal pretreatment method for downstream membrane processes such as reverse osmosis or electrodeionisation (EDI)
- The ultrafiltration process is easy to automate using a PLC controller
- Falling production cost of ultrafiltration membranes and ultrafiltration membrane units
