Published project: 500 LPH campus drinking-water plant
RO, sanitisation and filling, with approximately 4,000 litres of daily production capacity.
See the project and design assumptions → · Discuss your requirement →
When is commercial RO the right choice?
Start with the water problem, not a catalogue capacity.
Reverse osmosis uses membranes to reduce dissolved salts and selected contaminants. Whether your site needs RO depends on the source-water analysis and the quality required for its intended use—not TDS alone.
Hardness is the issue?
A commercial water softener addresses hardness. It does not replace RO where dissolved-salt reduction is required, and may form part of RO pretreatment.
Filtration or UV?
Filtration and UV systems address different treatment needs. The appropriate stages depend on the water analysis and intended use.
Plan the complete system
Review pretreatment, storage, recovery and reject handling before selecting equipment. Explore the commercial water-treatment services if your site needs more than RO.
Capacity and quotation inputs
How we size your commercial RO plant
LPH means litres of treated water produced per hour. Capacity depends on how much water you need, when you need it and the hours available to produce it.
Share the source and available test results to guide treatment and membrane protection.
Estimate daily use and busy periods, including equipment or batch requirements.
Tell us when the plant can run and what treated-water storage is available.
Review space, utilities and where water not retained by RO can be routed.

Compare commercial RO quotations on the same basis
An equipment price and a complete installed-system quotation may cover different work. Ask for the design basis, inclusions and exclusions in writing before comparing totals.
| Quotation item | What the proposal should make clear |
|---|---|
| Capacity and water quality | Rated LPH, feed-water assumptions, operating hours and treated-water target. Rated output is not a guarantee of the same production at every site; use the RO sizing guide to prepare your demand brief. |
| Treatment equipment | Which pretreatment stages, membranes, pumps, instruments and controls are included, and why they are needed for the tested source water. |
| Installation and utilities | Who supplies and connects tanks, pipework, electrical work and drainage. State civil work, access requirements, transport and applicable taxes separately where relevant. |
| Recovery and reject water | The proposed recovery basis, feed-water requirement and reject-water route. Compare these assumptions alongside treated-water output, not as a standalone recovery promise. |
| Commissioning and handover | Agreed startup checks, water-quality verification, operating instructions and acceptance criteria. Confirm responsibilities before installation starts. |
| Running costs and support | Consumables, membrane replacement assumptions, power and water use, warranty terms and AMC scope. Check what is chargeable rather than assuming the equipment price includes ongoing service. |

Commercial RO FAQ
Clear answers before you compare proposals.
What does a commercial RO plant cost?
Commercial RO plant cost depends on feed-water quality, required output, pretreatment, storage, reject handling and installation scope. Compare quotations on the same design basis, with equipment, site work and ongoing costs clearly separated. Share your site brief to discuss an appropriate scope.
How do you decide the RO capacity?
We consider treated-water demand, peak use, operating hours, storage, feed-water quality and the required continuity. Capacity is engineered from those inputs, not selected from a generic LPH table.
What recovery should we expect?
Recovery depends on the feed water, membrane design, pretreatment, operating conditions and the site’s reject-water plan. We discuss an achievable operating range after reviewing the water and application.
Does every site need an RO plant?
No. RO is appropriate when dissolved salts or a defined water-quality target require it. Softening, filtration, UV or another combination may be better for hardness, turbidity or microbial-control needs.
What maintenance does a commercial RO system need?
Planned checks, pretreatment service, cartridge and membrane care, instrumentation checks and operating records help protect performance. DhwaNeer can support a service or AMC plan for the installed system.
Can you replace or upgrade an existing RO?
Yes. We can review the current plant, water quality, operating history and site constraints before recommending a replacement or upgrade path.
