UNDERSTANDING THE RO
To understand reverse Osmosis we must first understand the osmosis. During natural osmosis, water flows from a less concentrated solution through semi permeable membrane to a more concentrated saline solution until concentrations on both sides of the membrane are equal.

Reverse Osmosis:
Reverse osmosis requires external pressure to reverse natural osmotic flow. As pressure is applied to the saline solution, water flows from a more concentrated saline solution through the semipermeable membrane.

Reverse Osmosis Membrane Elements:
A reverse osmosis membrane has a thin micro-porous surface that rejects impurities, but allows water to pass through.

The membrane rejects bacteria, pyrogens, and 85%-95% of inorganic solids. Polyvalent ions are rejected easier than monovalent ions.

Organic solids with molecular weight greater than 300 are rejected by the membrane, but dissolved gases pass through.

Reverse osmosis is a percent rejection technology. The purity of the product water depends on the purity of the inlet water. The purity of reverse osmosis product water is much higher than the purity of the feed water.
OUR LINE OF DUTY:
TWESCO is specialized in designing & manufacturing commercial & industrial reverse osmosis (RO) water treatment and purification systems for over 9 years with over 205 water purification systems built, including 53 customized systems. They generate 270 million gallon of purified water every day for more than 110 companies and individuals in over 5 East African countries. Our engineers design & build customized water treatment & purification systems including water softeners, waste water treatment, sewage treatment, RO water filtration, UV water purification, reverse osmosis plants, brackish & tap water reverse osmosis systems, sea water reverse osmosis systems, nanofiltration systems, ultrafiltration systems, RO cleaning skids, cartridge filters housing, deionizers, containerized equipment, electrodeionization units, UV sterilizers, and chemical dosing.
