05 Prefilter

There are a variety of different pre-filters. What they all have in common is that they prepare the water for the actual process.

Coarse filters:
Pure particle filters, e.g. sock filters, fleece filters, coarse filters for pressure application for ultrafiltration and reverse osmosis, micro filters for protecting adjustment valves.

Activated carbon filters:
For the removal of oxidants: protect reverse osmosis membranes.

Iron removal / demanganization:
protects membrane systems (UF, RO) from blockage

Antiscaling / hardness stabilization:
protects reverse osmosis plant from blockage

Softening:
Protects reverse osmosis systems and improves the recovery.

Disinfection:
protects filtration plants from bacterial growth

Ultrafiltration:
for raw water with a high particle load (e.g. seawater), UF protects reverse osmosis plants from premature membrane damage
