Brackish Water RO Membrane Supplier & Distributor in India

ScientificEdge is a trusted B2B distributor and sourcing partner supporting membrane elements, pressure vessels, antiscalants, cartridge filters and RO plant spares from a single desk, so a retrofit or a new build does not have to be split across several vendors.

The practical value is in selection and paperwork: matching feed TDS, flux and cross-flow to the right element variant, coordinating datasheets and test reports where the brand issues them, and invoicing in the form your procurement process needs.

It is element size and therefore plant flow. A 4040 is 4 inches in diameter and 40 inches long; an 8040 is 8 inches by 40 inches and carries roughly four times the active area, so it reaches a given permeate flow with about a quarter of the elements and vessels.

4040 suits compact and staged plants, typically below about 5 m³/h. 8040 suits industrial plants above that, where fewer vessels means fewer interconnections and seals. Element size cannot be mixed within an array, because vessel bore, adapters and brine seals are all size-specific.

Typically 1,000 ppm to 10,000+ ppm TDS, which covers most inland borewell, municipal and process feed in India. Above roughly 10,000 ppm the design moves toward high-rejection brackish or seawater elements at higher pressure.

TDS sets the operating pressure, but it does not set the recovery. Hardness, silica, sulphate and barium concentrate in the reject and usually reach saturation before salinity becomes limiting, so those parameters decide how far recovery can be pushed.

Low energy elements deliver comparable rejection at a lower applied pressure, typically around 100 to 150 psi against the higher pressure a standard element needs, which reduces pump duty and running cost.

The trade is a small reduction in rejection. On a continuously running plant at low feed TDS the energy saving usually repays it; on an intermittent plant, or where permeate quality drives the specification for an EDI stage downstream, the standard high-rejection element is often the better choice.

Whenever the feed carries a significant organic or biological load — treated effluent from an ETP or STP, wastewater recycling, high-silica streams, or any plant whose history shows differential pressure climbing between cleans.

FR construction uses a wider feed spacer and a modified surface charge so foulants adhere less and clean off more completely. It is not a substitute for pre-treatment: on effluent recycle the normal arrangement is still a UF or MBR barrier ahead of the RO.

Yes. Send the feed water analytical report, the plant design capacity, the vessel array configuration and the operating parameters, and the element class, size and quantity can be worked against that duty.

Where the analysis is incomplete we will tell you which parameter is missing rather than assume a value. Silica and hardness are the two most often absent from borewell reports, and both cap recovery.

Yes. Technical datasheets, nominal salt rejection specifications, element dimensions and manufacturer test reports can be coordinated where the respective brand makes them available for the supplied batch.

Availability depends on the brand, the product and the batch, so it is confirmed once stock and brand specifications are established rather than promised in advance. State the documentation you need at enquiry so it is arranged with the quotation.

Yes. Bulk orders, recurring OEM supply, rate contracts, institutional purchases and tender requirements are all supported, with GST-compliant billing and pan-India logistics.

For tender work, send the documentation format your procurement process requires along with the technical scope, so the quotation is issued in a form you can submit without rework.

Sourcing and distribution enquiries are supported for reputed global and domestic brands including DuPont Filmtec, Hydranautics (Nitto), Toray, LG Chem, Vontron, Toyobo and CSM, along with equivalent high-performance 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. Despatch is coordinated from Delhi NCR across India, covering plant, project, institutional and commercial sites.

Lead time is confirmed per line item at quotation stage, because stocked consumable lines and made-to-order elements differ substantially. Tell us the delivery city and the target timeline with the enquiry.
