Industrial RO Plant Supplier & Distributor in India

ScientificEdge is a B2B distributor and sourcing partner covering the whole plant BOQ from one desk — skid, pre-treatment, vessels, membranes, high-pressure pumps, CIP, dosing, instrumentation and piping — so interfaces are settled at quotation stage rather than discovered during commissioning.

The practical value is in sizing and paperwork: matching feed chemistry, recovery targets and peak demand to the right configuration, coordinating P&ID schematics, datasheets and projections where the manufacturer issues them, and invoicing in the form your procurement or tender process requires.

From roughly 500 LPH to 50,000+ LPH, which is about 0.5 to 50+ cubic metres per hour. Below about 2,000 LPH the plants are compact 4040 or single-vessel 8040 skids; from 3,000 to 10,000 LPH they are standard multi-vessel 8040 skids; above 15,000 LPH they are multi-stage 8040 arrays.

Size the plant on peak hourly demand rather than on daily total. A facility using 40,000 litres a day is not a 1,700 LPH plant if the draw arrives in a four-hour window — it is a larger plant, or a smaller one with storage sized to bridge the peak.

A single pass sends the feed through one RO stage and typically achieves 96 to 99 percent salt rejection, landing permeate in the tens of microsiemens per centimetre. That suits most process, utility and boiler pre-treatment duty.

A double pass treats the first pass permeate a second time, commonly reaching below 2 to 5 µS/cm. It is specified where the requirement genuinely demands it — pharmaceutical purified water feed, high-pressure boiler makeup, high-purity manufacturing — because it costs more to buy and to run. Where the specification does not demand it, a single pass with correct pre-treatment is the better plant.

The usual train is a multi-media or sand filter for suspended solids, activated carbon or metabisulphite dosing for free chlorine, a softener or antiscalant dosing for hardness and scaling salts, and 5 micron cartridge filtration immediately before the high-pressure pump.

What the plant actually needs comes from the raw water analysis. High SDI calls for ultrafiltration rather than media filtration alone; iron and manganese need oxidation and a solids barrier; high organic load calls for a UF or MBR barrier. Free chlorine in particular must be removed — it damages polyamide membranes irreversibly, and no cleaning recovers them.

Recovery is permeate flow divided by feed flow, expressed as a percentage. A plant taking 100 m³/hr of feed and producing 75 m³/hr of permeate is running at 75 percent recovery, with 25 m³/hr going to concentrate.

The achievable figure is set by the concentrate chemistry rather than by the pump. At 75 percent recovery the feed is concentrated four times at the tail of the array; at 85 percent, nearly seven times. Whichever sparingly soluble salt saturates first — usually silica or calcium sulphate in Indian groundwater — caps the recovery, and no amount of pressure buys past it.

Where the site has no suitable building, where the plant must move between locations, where the requirement is temporary, or where commissioning time matters more than capital cost. A container arrives with pre-treatment, RO skid and CIP already installed and interconnected, and needs only power, feed and drain connections.

A conventional skid inside an existing plant room is usually less expensive for the same capacity and easier to expand later. The container is bought for mobility, speed and site independence, not for treatment performance — the process inside is the same.

P&ID and process flow schematics, electrical single-line diagrams and membrane projection calculations can be coordinated where the respective manufacturer makes them available. ROSA is DuPont's legacy projection software, now superseded by WAVE; IMSDesign is Hydranautics'. The projection is produced with whichever tool matches the membrane being quoted.

A projection is a model rather than a performance guarantee, and its output is only as good as the inputs. Send the raw water analysis, the temperature range and the required permeate flow with the enquiry, and ask for the projection at the coldest month the plant will operate in rather than at 25 °C.

Yes, and replacement is a large part of the enquiry volume on this category. Membranes, pressure vessels, high-pressure and booster pumps, mechanical seals, CIP skids, dosing pumps, cartridge filters, instrumentation and control panel components are all supplied for plants already in service.

Send the existing plant capacity, the element model and vessel configuration currently installed, and the pump make and model if it is being replaced. Where the original component is discontinued, an equivalent can usually be offered — but the interface dimensions and pressure class need confirming rather than assuming, so include a photograph of the existing installation where you can.

Sourcing and distribution enquiries are supported for reputed global and domestic brands including Grundfos, CNP, Pentair, Wave Cyber, DuPont Filmtec, Hydranautics, Toray, Vontron, Schneider and Siemens, along with equivalent options.

This is subject to stock availability, buyer specification, technical compatibility and documentation, and does not indicate authorised distribution, official dealership or an exclusive partnership with any brand.

Yes. Dispatch is coordinated across Delhi NCR, Gujarat, Maharashtra, Tamil Nadu, Telangana, Karnataka, West Bengal and other industrial corridors, covering factory, project, municipal and institutional sites.

Lead time is confirmed per line item at quotation stage, because a stocked pump and a made-to-order skid differ substantially. Complete plants also need site readiness — foundation, power and drainage — confirmed against the delivery date, so tell us the site location and the target project schedule with the enquiry.
