Reverse Osmosis Systems

The RO process removes most of the dissolved mineral salts, almost all of the particulate matter and most of the dissolved organic compounds.
 

The driving force of the reverse osmosis process is driven by both the feed water pressure and the concentration differentials across the membrane surface. For water, the pressure effect is the most important, and for the dissolved ions in the water, the concentration difference is the most important. Therefore, increases in pressure increase the amount of treated water without causing a corresponding increase in waste flow.

Water molecules penetrate the thin layer of the membrane and diffuse through it molecule by molecule. Dissolved salt ions would also diffuse through this layer, except that the solubility of the salt ions in the feed is much less than that of the water. This results in water passing through the membrane more rapidly than salts, causing separation.

As pressure is applied to the concentrated solution, the flow is reversed and water is passed through the membrane from the concentrated side to the dilute side.

Reverse Osmosis is a membrane process that acts as a molecular filter to remove over 99% of all dissolved minerals. Water passes through the membrane while the dissolved and particulate matter is left behind.

WHAT IS REVERSE OSMOSIS

Water containing impurities is passed out of the element along the surface of the membrane and is not able to enter the tube.

Raw water containing salts and impurities is fed into the membrane element, and feed the pressure supplied by the RO system pump forces the water through the pores in the membrane for collection in the product tumbe in the centre of the membrane element.

The 14T uses spiral wound RO elements constrcted from a thin-film composite membrane material.

RO is capable of removing 98-99.5% of the Total Dissolved Solids (TDS) and 99% of all bacteria, providing ultrapure water for any application.

The reverse osmosis process uses a semi-permieable membrane to separate and remove dissolved solids, organics, pyrogens, sub-micron collodial matter, viruses and bacteria from water.
