Osmosis is the process which takes place when a solution is separated from a less concentrated solution by a semi-permeable membrane.

The membrane will allow water molecules to pass through, but not larger molecules, so that it can act effectively as a molecular filter.

During osmosis, the water molecules in the more diluted solution will migrate into the more concentrated solution equalising concentration on both sides of the membrane.

This migration can be stopped, and indeed reversed, by the application of a pressure gradient in opposition to the natural direction of flow. Thus, water molecules can be forced to migrate from the more concentrated solution to a less concentrated solution.

This machine is supplied with an water softening system with conductivity control and tank for salt tablets used in the back flushing process.

The Softener is pre-treatment for the RO it reduces the Calcium Hardness so it does not reject massive amounts of water when it’s in service

 The Water Softeners require the Salt Tank to regen the Softener Resin and is NOT connected to the RO in any way

 The Small White Tank is the CIP Tank this is piped onto the RO Pump Inlet and is connected to the  RO Waste Water and Permeate Outlet to enable the water to be recirculated through the Membranes for cleaning purposes

The Elga reverse osmosis section is supplied with 3 x RO Cartridges, flow control meters, and conductivity display.
