News: Reverse Osmosis Water Filters Soon With Manhattan/CDT Technology

You may have heard about Reverse Osmosis Water Filters before. We certainly had, when we were first contacted by a technical representative working for a well known US-based manufacturer that produces different types of residential water processing systems.

The said manufacturer was in need of a technical solution to solve a problem he had with one of his reverse osmosis filter systems that applies a pump to increase water pressure. In short: Whenever feed water pressure was very low and the pressure pump had to increase the pound-force per square inch (psi) by roughly more than 18, leaks would likely occur at vulnerable points in the filter system.

Although cable insulation is our core competency, our developing engineers could use their broad knowledge to come up with a creative solution. Therefore we can proudly announce that Manhattan/CDT technology will soon be integrated in 2 re-designed reverse osmosis water filter models.

A Brief Overview Of Reverse Osmosis

Reverse osmosis is a water purification technology that uses a semi-permeable membrane to remove ions and larger particles like bacteria from water. In a reverse osmosis system a pressure pump is used to apply external pressure and overcome osmotic pressure. Thereby the flow of water molecules is reversed. The result: Pure water as a solvent passes through the semi-permeable membrane whereas almost all solutes are retained on the pressurized side.

Reverse osmosis is most commonly used for the desalination of sea water in industrial plants. Fresh water applications are wastewater treatment, concentration of food liquids, drinking water production, and maple syrup production.

Although the purity level of processed water largely depends on feed water condition, water pressure and water temperature, sophisticated filter systems are capable of removing about 97.6 percent of all contaminants. This includes asbestos, cadmium, chromium, copper, fluoride, lead, mercury, nickel, sodium, acrylamide, carbon tetrachloride, ethylbenzene, Dioxin, and THMs.

Compared to other water purification technologies, reverse osmosis is not only the most effective, but also an efficient choice in terms of energy usage. Distillation provides the highest level of water purity, but requires a lot of electricity for the heating of water. Ultrafiltration and other gravitation based separation processes usually require the least amount of energy, but cannot meet the purity standards set by reverse osmosis filters.

Manhattan/CDT – Future Prospects

Getting a first insight in the technology behind reverse osmosis water filter systems and how they work has ignited a spark that has pointed us in the direction of new business sectors. Manhattan/CDT already has the expertise that is needed to get a foot in the door of a vast market targeting residential water treatment.

In the medium term, we are going to integrate our technology into other third party products. In the long term, we plan to expand into multiple markets with new fields of business such as the pilot project described before.
