INTRODUCTION TO REVERSE OSMOSIS

What Is It ?

Reverse Osmosis Units are a series of pressure vessels called “housings” with a number of membranes installed. Water chemistry and hydraulics determines the number of housings and membranes required. High-pressure pumps are used to process water through the membranes. RO membranes are not intended to operate as physical filters. Suspended matter must be removed upstream of the RO System.

How The Membrane System Works ?

Osmosis separates impurities from water by passing it through a semi-permeable membrane. The semi-permeable membrane allows only very small atoms and groups of atoms (such as water molecules, small organic molecules and gases) to pass through it. Hydrated ions that have been dissolved and are therefore surrounded by water molecules cannot pass through the membrane. Reverse Osmosis (RO) effectively takes advantage of the osmosis process. By applying pressure to the feed stream, one can reverse the natural osmotic effect, resulting in removal of contaminants from the fluid.

The spiral membrane is constructed of one or more membrane envelopes wound around a perforated central tube. The permeate passed through the membrane  into the envelope and spirals inward to the central tube for collection.
