Facility managers are an operation’s first line of defence when it comes to water quality. Over time, you may have noticed that your facility’s water quality has declined. You may have discovered worrying and increasing levels of bacteria in the water. Reverse Osmosis is a very effective means of removing many contaminants from industrial water. But how well does it work to remove bacteria? The following article will provide an overview of the reverse osmosis process, including what it does and does not remove.

For industrial water purification, sodium removal is a rare requirement as it is not present in the mains water supply for most western countries. Sodium can, however, be present in the water supply in some coastal areas around the world and in countries that use a lot of road salt, and is also usually present in water that has been softened.

Receiving the best possible performance from your RO membranes is very important to maximise the volume of water recovered as RO permeate, Minimise the amount of electrical energy consumed and maximise the quality of RO permeate produced.

An increasing number of purified water system users have changed over to RO. This is mostly born about by a desire to get away from the use and storage of regeneration chemicals. A further benefit is the removal of a chemical discharge during regenerations.

The truth is that in many cases conventional Deionisers are still the best solution. There are many users who will always use reverse osmosis because they value the physical barrier and validity that a performing RO membrane provides. However, water consumption and capital cost should always be considered when making the choice.

These Pro’s and Con’s may assist in an informed choice.

Waste water is becoming an ever-increasing and infinitely valuable water resource. Treated industrial waste water can be transformed into a product that can be used for numerous applications, including wash water, industrial process water, surface irrigation, wetlands and ground water recharge, to name but a few.

Many industries are realising the benefits of reverse osmosis (RO) water purification systems. However, the main question about them is how much they cost. The fact is that the cost of an RO system will depend on how much treated water is required, and so will vary widely. Generally speaking, industrial reverse osmosis systems can range in price from £11,000 to £29,000.
