Reverse Osmosis Systems
Reverse Osmosis Plants
Generate purified water for drinking, cleaning, and manufacturing processes.
Reverse osmosis is a process for creating pure water by separating and removing the dissolved solids present in water. It is a safe and chemical free method for generating a constant supply of high quality water for commercial and industrial applications.
Reverse osmosis water has a high purity level which is suitable for many manufacturing processes and to treat borehole water. Reverse osmosis plants do not need to regenerate and there’s no downtime. ROs produce a continuous flow of water.
What are reverse osmosis water treatment systems used for?
Reverse osmosis water treatment is used to remove the dissolved particles and minerals present in water to produce a continuous supply of treated water.
Commercial reverse osmosis water treatment systems are used within food and beverage production and in automotive, metal, and pharmaceutical manufacturing. Reverse osmosis water is useful for water jet cutting and glass, boiler, and cooling tower processes.
Key benefits of reverse osmosis plants to treat water:
1. Continuous supply of purified water – with no regeneration or downtime.
2. Low energy requirements – compared to other methods.
3. Get the flow rates needed – from 300 litres an hour to 30,000 litres an hour.
4. Reduce water waste – only 25% of feed water is rejected and it’s possible to use this water elsewhere on-site for cleaning purposes.
5. Minimal operating costs – with no chemicals required.
How Reverse Osmosis Plants Work
Here’s a step-by-step overview of how reverse osmosis works:
1. Water is forced under pressure through RO membranes.
2. Pure water pushes through the membrane.
3. Small particles, such as bacteria, chemicals, salts, and heavy metals, are left behind on the other side of the membrane.
4. The reject water containing the contaminants goes down the drain or can be reused.
5. A steady flow of pure water is created.
How does it happen?
In an RO system, water is forced through a semi-permeable membrane which rejects all unwanted impurities. The membrane only allows pure water molecules to flow through, resulting in contaminants including bacteria, chemicals and heavy metals being removed and flushed to waste.
For example, if a solution of salts in water is separated from a source of pure water by a semipermeable membrane, the pure water passes through the membrane to dilute the salt solution which forces pure water through the membrane, thereby concentrating the salt solution.
A Reverse Osmosis plant uses this same effect to purify water containing a high level of natural salts without chemical regenerates such as acids and caustic.
How do I know if Reverse Osmosis is the way to go?
The way to find out is to arrange a site survey. During a site survey, our water treatment engineers assess your operation and test your water quality. By looking at your current water supply and discussing the level of water quality you require, we can recommend the best water treatment system for your business.

Common Questions on Reverse Osmosis Systems
Why is Reverse Osmosis a safe and efficient option?
Reverse Osmosis systems do not require the storage or handling of harmful chemicals, making it the safer way to produce pure water for many commercial and industrial applications.
It’s efficient because the plant does not need to be taken out of service to regenerate as a Demin plant would, ensuring continuous water availability.
Does Reverse Osmosis water require pre-treatment?
The RO plant must be supplied with softened water, and a duplex unit is recommended. The high output reverse osmosis plant offers considerable advantages over traditionally deionization systems, with no caustic consumables or problems with COSHH compliance.
What are the operating costs of reverse osmosis units?
The operating costs are minimal when compared with other water treatment processes that require a high level of consumables. There are electricity costs associated with running the equipment continuously, but no other power or fuel is required.
Reverse osmosis units require maintenance and servicing, including changing the filters every three to six months. The easiest way to manage this is by scheduling regular servicing with our engineers. This provides peace of mind your equipment is performing as it should and prevents downtime. We can instruct your operatives on basic maintenance.
Is reverse osmosis suitable for creating drinking water?
Reverse Osmosis water is safe for drinking, but we wouldn’t recommend it. This is because all the vitamins and minerals have been removed, which is essentially the good stuff!
RO water doesn’t quench your thirst like normal drinking water as the salts have been removed and it tends to be slightly more acidic.
When we use an RO system to treat borehole water for drinking, we install a blend valve that puts some mains water back into the drinking water supply to avoid the issue above.
The Demin vs. RO Debate
What’s the best method of water purification for industrial and commercial use?
Should you choose Twin Bed Deionization or Reverse Osmosis (RO)?
It’s a long-standing debate but the truth is either system works if it’s designed for your operation. The performance of both methods has come a long way, as has the equipment. The question should be which system is best suited to your business’s needs.
