Commercial RO plants, engineered around your water and demand.
Consistent treated water starts with the right design brief. DhwaNeer reviews your source water, process demand and site constraints before engineering, installing and supporting a commercial RO system.
Start with the water problem, not a catalogue capacity.
RO can reduce dissolved salts and selected contaminants, but it needs the right pretreatment, operating plan and reject-water approach. We help you decide when it is appropriate—and when softening, filtration, UV or a combination is the better fit.
01
RO is a fit when
TDS, salinity or a defined water-quality target is driving the requirement.
02
Pretreatment matters
Media filtration, softening, dosing or cartridge protection may be needed before the membranes.
03
Plan the reject
Recovery and reject handling should be considered before equipment is selected.
04
Sometimes RO is not right
Hardness, scale, turbidity or microbial risk may call for another treatment stage first.

Capacity follows the brief
Capacity is a design outcome, not a price-list number.
We use source-water quality, treated-water use, operating hours, peak demand, storage and acceptable recovery to shape the plant brief. That keeps the proposal grounded in your site rather than a generic LPH claim.

Capacity orientation
Start with the operating pattern, then calculate LPH.
These planning bands help frame the conversation without pretending that one catalogue capacity fits every site.
Compact commercial use
Point-of-use drinking water, cafés, smaller kitchens and defined equipment loads where demand and storage are predictable.
Hospitality and foodservice
Restaurants, hotels and central kitchens with daily peaks, hygiene requirements and service-continuity constraints.
Institutional and campus
Schools, hospitals, offices and residential campuses where storage, distribution and redundancy shape the plant.
Process and industrial
Manufacturing, boiler, ingredient or utility applications governed by a specific treated-water target and operating window.
Final capacity depends on feed-water quality, treated-water demand, peak use, operating hours, storage, recovery and continuity—not application name alone. Read the commercial RO sizing guide →

Know the design basis—not just the equipment list.
Scope varies by site, but a responsible commercial RO proposal should make these decisions visible.
Water and design basis
Feed-water assumptions, treated-water target, demand, operating hours and continuity requirement.
Treatment and recovery
Pretreatment, membrane stage, instrumentation, expected recovery basis and reject-water approach.
Site integration
Storage, distribution, plumbing, electrical requirements, access, installation and commissioning scope.
Lifecycle support
Operating handover, consumables, warranty applicability, exclusions and available service or AMC options.
From brief to reliable water
One accountable path from diagnosis to support.
Step 01
Understand
Review the water report, application, demand and site constraints.
Step 02
Engineer
Define pretreatment, RO, recovery, storage and integration requirements.
Step 03

Keep the system serviceable with planned maintenance, spares and AMC.
Commercial RO FAQ
Clear answers before you compare proposals.
What does a commercial RO plant cost?
There is no responsible single price without the water quality, capacity, pretreatment, storage, reject approach and installation scope. Share the brief and we can define the right proposal basis.
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.
