RO water plant
High-purity water with reverse osmosis
Reverse osmosis pushes water through a semi-permeable membrane with pores far smaller than salts, metals and microorganisms. Clean water passes through, while the rejected impurities are flushed away — giving you water with very low total dissolved solids (TDS).
An RO plant only performs well when the pre-treatment, pressure and recovery are designed correctly for the feed water. That is why every plant we build starts with a water analysis and ends with a performance test at handover.
Our RO plant services
- New RO plant design, supply and installation
- Membrane cleaning (CIP) and replacement

Why clients rely on us
Engineering you can depend on
Quality at every step
We select vessels, membranes, media and pumps that suit local water conditions, and we test the treated water before handover so you can see the result for yourself.
Modern treatment technology
RO, UF, ion exchange, multimedia filtration, UV and automated controls — we combine proven technologies into a plant that is efficient to run and simple to operate.

What an RO plant removes
When conventional filters are not enough — because the contaminants are dissolved in the water — reverse osmosis is the most reliable answer.
-
High TDS & salinity
Reduces dissolved salts from brackish and coastal groundwater.
-
Arsenic & heavy metals
Removes arsenic, lead, cadmium and other metals to safe levels.
-
Nitrate & fluoride
Cuts contaminants that ordinary filters cannot trap.
-
Hardness for process use
Delivers low-mineral water for boilers and sensitive machines.
-
Microorganisms
The membrane is a physical barrier; UV adds a final safety step.
-
Taste & odour
Produces clean-tasting water for drinking and bottling.
Inside an RO plant
How our RO plants work
Good pre-treatment protects the membranes and keeps running costs low.
-
1
Pre-filtration
Sand or multimedia filters remove suspended solids and silt.
-
2
Carbon filter
Activated carbon removes chlorine and organics that damage membranes.
-
3
Antiscalant & micron filter
Dosing prevents scaling; a 5-micron cartridge catches fine particles.
-
4
High-pressure RO
A pump drives water through spiral-wound RO membranes.
-
5
Post-treatment
Remineralisation and UV prepare water for storage and use.

Benefits of an RO water plant
-
Consistently low TDS
Stable output quality regardless of seasonal changes in feed water.
-
Broad contaminant removal
One process removes salts, metals, nitrates and microorganisms.
-
Great-tasting water
Ideal for drinking water points, canteens and jar bottling.
-
Protects equipment
Low-mineral water prevents scale in boilers and cooling systems.
-
Automatic protection
Low-pressure, high-TDS and tank-level controls protect the plant.
-
Low cost per litre
Well-designed plants deliver pure water at a very economical rate.

RO water plant — FAQ
How often should RO membranes be replaced?
With proper pre-treatment and regular cleaning, commercial membranes typically last two to three years. Poor pre-treatment can shorten this considerably.
Why has my RO plant output dropped?
Common causes are clogged pre-filters, membrane fouling or scaling, low feed pressure or a worn pump. Our technicians diagnose the cause before replacing any parts.
How much water does an RO plant reject?
Commercial plants usually recover 50–75% of feed water depending on water quality and design. Reject water can often be reused for washing or gardening.
Do you service RO plants from other companies?
Yes. We service, repair and upgrade RO plants of all brands and capacities.
