OSMO Membrane Systems GmbH products

OSMO Membrane Systems GmbH is excellently grounded in high pressure reverse osmosis systems with a working pressure up to 160 bars (2300 PSI). So, very high salt contents can be reached. Thus, especially for downstream evaporators, the evaporation volume flow can be reduced significantly which means enormous reductions in plant capacity and energy consumption.

During the production process of basic organic chemicals, very often condensates occur as byproducts, which have to be treated before dumping or recycling into production process. The condensate occurring at the product process of caprolactame contents for example ammonium sulfate and caprolactame.

In many applications of the chemical industries, a concentration by evaporation of mixtures and brines is necessary.

Membrane filtration plants of OSMO Membrane Systems GmbH offer various solutions for desalination. Hereby, we offer all stages of projecting – from proof of concept to costumized plant – from a single source.

Ultrafiltration System For separation of dissolved substances, ultrafiltration is applied apart from conventional pre-filters (sand and gravel filters). So, all solids and even bacteria, viruses, germs and colloidal components (iron, orthosilicic acid) are retained.

Reverse Osmosis System for the retention of dissolved salts and low-molecular Components, nanofiltration or reverse osmosis is suitable. With nanofiltration, multivalent ions and low-molecular components like e.g. humic substances can be retained. Nanofiltration can be used for reduction of hardness, separation of phosphates and sulphates, as well as for reduction of COD and DOC. With reverse osmosis – additionally to the nanofiltration – monovalent ions can be retained. Generally, with reverse osmosis very good retention rates for DOC can be reached, which especially matters at power plant applications.

With ion exchangers, permeate of reverse osmosis or other process waters can be completely demineralized. According to the VGB recommendations, a max. conductivity of 0,08 µS/cm is allowed for fully demineralised water.

With electro deionisation, permeate of reverse osmosis or other process waters can be completely demineralised. According to the VGB recommendations, a max. conductivity of 0,08 µS/cm is allowed for fully demineralised water.

The so called „Boiler feed water“ is stored in a feed water tank and continuously feeded to the boiler of a steam generator. A big quantity of feed water is needed for example in steam power plants. The boiler generates steam, which is used for heating, for chemical processes or for driving a steam turbine respectively a steam engine. The feed water is purified in a way, that all harmfull components for the boiler are removed or neutralized. Leakages and evaporation loss are compensated by additional water which is purified in the same way than boiler feed water.

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.
