Drinking water production by ultrafiltration

The ultrafiltration system is designed and built according to the high requirements of the Drinking Water Ordinance and the DVGW regulations. The mixed raw water from several springs and deep wells has a turbidity of approx. 40 FNU during rain events. This turbidity is filtered to <0.2 FNU. The water produced in this way is germ-free. This is followed by UV radiation and chlorination according to drinking water regulations.

Successful development work in the application of acid treatment

In close cooperation with a customer from the surface technology sector, OSMO has developed a new process for the recovery of spent phosphoric acid baths from printing plate production. Printing plates are pickled using phosphoric acid, which contaminates the pickling bath with small amounts of aluminium. The successful piloting of nanofiltration was followed by the commissioning of several plants, saving 75% of the fresh acid and reducing the amount of waste to only about 17% of the previous volume.

Paper manufacturer works with OSMO technology

OSMO built a customised full desalination boiler feedwater purification system for an existing industrial power plant of a renowned German corrugated paper manufacturer without interrupting steam production. The plant technology includes pre-filtration, conditioning, reverse osmosis and downstream softening to reduce operating costs. Reverse osmosis and softening can also be operated separately in an emergency, which increases the availability of the plant. The implemented automation enables scale control (prevention of maximum concentration) and remote maintenance is possible through visualisation. During the construction phase, OSMO produced demineralised water using a mobile containerised plant.

Treatment of nitrate-containing wastewater using high-pressure reverse osmosis

Conventional wastewater treatment processes remove the wastewater load simply and cost-effectively, but recovery and reuse of the water constituents is usually not possible. Selective membrane processes, on the other hand, make previously unused resources economically attractive, as the example of heavily nitrate-polluted wastewater treatment shows. The piloting of the treatment by high-pressure reverse osmosis was subsidised by the German Ministry for the Environment, Nature Conservation and Nuclear Safety with 2.6 million €. OSMO Membrane Systems supplied the pilot plant in container design and the large-scale plant ordered after successful piloting.

River water purification with ultrafiltration and reverse osmosis

Purification of river water for boiler feed saves expensive drinking water. For the production of process water, many companies rely on high-quality well or drinking water supplies. But stricter environmental regulations are steadily restricting the sourcing of these supplies and increasing costs.  An investment in modern membrane technology to produce boiler feed water from river water at low cost can therefore be worthwhile. The process used here is based on ultrafiltration with downstream reverse osmosis.
