RO Plants
Reverse-osmosis plants for high-quality drinking water at scale.
What this actually is
A commercial RO plant is a different proposition from a domestic purifier: higher throughput, proper pre-treatment, and a design built around the specific chemistry of your water source. These are systems that have to deliver consistent quality every day, so they are engineered around a water analysis rather than picked from a catalogue.
How the job runs
- 1
Water analysis
A full analysis establishes TDS, hardness, iron, turbidity and microbiological load. This drives the whole design — particularly the pre-treatment, which is where most underperforming plants actually fail.
- 2
Sizing and design
Throughput is specified in litres per hour against your real peak demand, with storage sized so the plant is not forced to run continuously at peak. Pump, membrane count and vessel layout follow from that.
- 3
Pre-treatment and membranes
Sediment filtration, carbon and softening or dosing protect the membranes from the things that destroy them — chlorine, hardness and suspended solids. Skimping here shortens membrane life dramatically.
- 4
Installation and commissioning
The plant is installed, plumbed and wired, then commissioned with output tested against the specification. We hand over with an operating routine and a service schedule.

The choices worth understanding
Capacity band
Plants are specified by litres per hour, from small units for a clinic or office through to systems serving a hospital, hotel or production line. Peak demand rather than daily total drives the sizing.
Pre-treatment train
Multi-grade filtration, activated carbon, softening and antiscalant dosing are combined according to the water analysis. This section is what determines membrane life and running cost.
Post-treatment
Ultraviolet, ozone or mineral cartridges finish the water for taste and microbiological safety. Which are needed depends on the application and on how the treated water is stored and distributed.
Straight answers
What capacity plant do I need?
It is set by peak demand and how much treated storage you have, not by the daily total on its own. We work backwards from your busiest period, because a plant sized only to the daily average will fall behind exactly when you need it.
What are the running costs?
Mainly electricity, periodic filter media, dosing chemicals and eventual membrane replacement. Good pre-treatment is the single biggest lever on that total, since it is what keeps membranes alive far longer.
How often do membranes need replacing?
It varies with feed water quality and how well the plant is maintained — years rather than months when pre-treatment is right and cleaning is done on schedule. Neglected plants can lose membranes far sooner, which is what an AMC is designed to prevent.
Do you handle the maintenance?
Yes. We offer annual maintenance contracts covering scheduled servicing, media replacement, membrane cleaning and water quality checks, so the plant keeps meeting its specification rather than quietly drifting away from it.
