High Purity media | Production of purified water

The production of purified water from drinking water requires technical processes according to highest hygienical standards. Wellmann Engineering provides PW-production units from 0.5 m³ / h up to several thousand liters per hour.

Purified water is produced through water softening, reverse osmosis and electrodeionization.

Orbital welded plants in stainless steel ensure highest product quality.

The plant control systems developed by our automation experts ensure continuous monitoring and analysis of performance and water quality even after long-term use.

All plants are qualified and documented according to international standarts.
