Rinsing - Import export

Rinse water treatment with nanofiltration (NF), reverse osmosis (RO) or electrodialysis (ED) By treatment with nanofiltration, reverse osmosis and electrodialysis, your rinse water can reused a couple of times. By the membrane plant, the pollution of the rinse water is separated and the particles are concentrated. Thereby the water costs and the disposal costs can be minimized. Additionally, materials in the water can be recovered much more easier by concentration.

Recovery of acids and acidic rinse waters Additionally to the pickling bath treatment by microfiltration and ultrafiltration, the recovery of acid becomes more and more important. Additionally to sulphuric and hydrochloric acid, also mixed acids (HF / HNO3) can be recovered. The first step of the acid recovery is mostly a sludge separation by microfiltration. Downstream, diffusion dialysis, electrodialysis or nanofiltration is used for metal separation. For the treatment of rinse waters, OSMO Membrane Systems GmbH offers reverse osmosis or electrodialysis plants.
