DWA pre-filtration concept

The DWA pre-filtration concept includes specific devices for different demands which are upstream of the Reverse Osmosis systems.

The configuration of the pre-filtration depends on the local raw water quality. Requirements for effective pre-filtration to archive drinking water quality for a safe and long-lasting operation of the Reverse Osmosis system are water analysis, measurement of the blocking index as well as the knowledge of the exact water hardness.

Changing raw water quality – also temporary nature – affects dimensioning of necessary pre-filtration and needs continuous monitoring.

Only an individual pre-filtration concept is protects the Reverse Osmosis and provides maximum operational safety and maximum cost effectiveness.
