Desalination - Import export

SW-O® unique 100% free chemical modular plant in the world. 1.- Coagulation contact: Uses a porous filter media to develop a type of bacteria that lives in the sea naturally. To attract particles from stable colloids, bacteria produce and covered so that same enzyme function as a glue. For this reason, the coagulants are not necessary to destabilize the colloids.   2.- Filter Media SW-O® filtration is faster (~ 10-15 of m / hr). A different bacteria, but also natural seawater, is set in the filter medium. This bacteria is able to permanently consume the dissolved organic material in the water. This bacterium causes the water to reach a state of "famine" or lack of oxygen. The absence of oxygen is key to maintaining corrosion at low levels. The filter backwash can now be downloaded to the sea without any treatment as this does not use chemicals.

Dye and product desalination 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. In times of increasing energy and raw material costs, desalination can be a remarkable contribution in the process chain, to cut running costs and to conserve resources. At the production of dyes, e.g. azo dyes, optical brightening agents (OBA) and so on, nano filtration plants are used for retention of pigments and elution of the present neutral salts (Na+Cl-). At the first production step, the content of sodium chloride will be reduced by dia filtration and addition of deionized water until the required salinity of permeate is reached. The proper selection of the NF membrane achieves the highest possible dye retention at the remaining NF concentrate. After this step, dye can be concentrated to the required values. So, different steps of production c

Complete desalination with ion exchangers 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.
