Puretech Water Systems (UK) Ltd offers a wide range of reverse osmosis and water softening plant to laboratory industry.
Our clients within this industry require a good consistent grade of purified water to serve their analysers as well as providing a base solution for the make up of various reagents. They are also use purified water for the cleaning of various glassware used within the laboratory environment.
We can design bespoke systems as well as offering water softeners and reverse osmosis plant from our existing comprehensive portfolio.
How does Reverse Osmosis work?
Reverse Osmosis is a high-pressure water process which forces water to be treated through a semi permeable reverse osmosis membrane. The membrane has two outlet channels. One being the permeate water (Purified) which passes the heavily filtered water onto the point of use application. This purified water typically has around 98% of the incoming contaminants removed, such as dissolved salts, bacteria, organics and pyrogens. The other outlet is where the rejected water (Concentrate) is sent directly to drain, or in some cases this concentrate water can be re-circulated back to the front of the reverse osmosis plant and re-processed to reduce water wastage.
What is a Water Softener?
A water softener is used to remove hardness from the incoming towns mains water supply. This is achieved by removing the calcium and magnesium ions which would otherwise cause scaling within a water system. Scaling can present itself in many ways, some of the most common are scaling of water heaters reducing their ability to heat water efficiently, scaling on glassware such as shower screens and glasses, scaling on tap outlets and scale build up within water holding tanks.
A water softener removes the calcium and magnesium ions and traps them on its filter surface which acts as a magnet. It then exchanges these calcium and magnesium ions for sodium ions which then creates soft water which exits the water softener ready for consumption.
