Reverse Osmosis

“Reverse osmosis is a physical process for the concentration of substances dissolved in liquids, wherein the pressure is reversed with the natural osmosis process.

The medium in which the concentration of a particular substance is to be reduced is separated by a semi-permeable (semipermeable) membrane from the medium in which the concentration is to be increased. This is exposed to a pressure that must be higher than the pressure generated by the osmotic desire for concentration equilibration. This allows the molecules of the solvent migrate against their “natural” osmotic propagation direction. The process it presses into the compartment in which the less concentrated solutes are present.

In contrast to a conventional membrane filter osmosis membranes do not have through-pores. Rather, the ions and molecules migrate through the membrane by diffusion through the membrane material.

EnviCare® Engineering GmbH integrates reverse osmosis processes in wastewater treatment and mass transfer processes.

Reserve Osmosis can be used in a wide variety

Especially in the field of landfill leachate treatment, the non-selective restraining behaviour shows significant advantages, since all larger substances are removed reliably from the clean water. In addition, the quality can be monitored very easily and safely via a reliable sum parameter. On a worldwide scale reverse osmosis becomes ever more common especially in the area of drinking water production.
