Toray TM820V

Toray TM820V-400 SWRO 8040 selection needs salinity, pressure, vessel fit, pretreatment, recovery, stock, and permeate target.

Toray TM820V-400 for seawater RO membranes

Toray TM820V-400 is a low-energy 8040 SWRO membrane for seawater desalination; Watermart’s summarized Toray data lists 400 ft² active area, 9,000 gpd test flow, 99.80% stabilized salt rejection, and a 34-mil feed spacer. PT Watermart Perkasa supplies RO membranes in Indonesia, but TM820V-400 selection still depends on salinity, temperature, pressure, recovery, pretreatment, vessels, and the project permeate target.

Updated 9 August 2026: this page adds a Toray TM820V-400 decision path for 8040 SWRO membrane requests, element replacement, and quotation data.

Fast data for a Toray TM820V-400 quotation

Direct answer: a Toray TM820V-400 price request should state the complete model, element quantity, wet/dry condition, 8040 vessel, salinity, temperature, recovery, and permeate target. Watermart can check availability and early fit, but the final design still needs a membrane projection and site operating conditions.

Toray TM720D-400 for brackish-water RO

Toray TM720D-400 is a high-rejection brackish-water RO membrane in the TM700D series; the linked Toray brochure lists 400 ft² active area, a 34-mil feed spacer, 11,000 GPD test flow, and 99.8% stabilized salt rejection. PT Watermart Perkasa supplies it in Indonesia and matches it to feedwater, pressure, recovery, pretreatment, vessel layout, and permeate target; catalog figures do not guarantee production.

Choose TM720D-400 or TM720D-440 from the system design

TM720D-400 and TM720D-440 belong to the same high-rejection series, but they are not automatic replacements for one another. The 400 model has 400 ft² active area and a 34-mil spacer; the 440 lists 440 ft² and a 28-mil spacer. Area, spacer, test flow, pressure drop, flux, element count, and feed conditions belong in the projection before a model is placed on a quotation or purchase order.

Source: the Toray TM700D manufacturer brochure, January 2024 revision. Compare other series on the Toray brackish-water membrane page, then send the water analysis, temperature, permeate target, recovery, pressure, vessel configuration, existing model, quantity, and location through the Watermart contact form. Drinking-water projects still require commissioning, sanitation, consumables records, representative sampling, and laboratory verification against applicable Indonesian requirements.

Why must a Toray RE8040-BE request be verified?

A request for a “Toray RE8040-BE” membrane price should be held until the brand and label code are confirmed. The catalogue on this page lists RE8040-BE under CSM, while the Toray pages use different code families; a shared 8-inch format does not establish identity, duty, test conditions, or replacement fit.

Information to provideDecision it supports
Existing element label and packaging-brand photosDistinguishes CSM RE8040-BE from the actual Toray model
Complete model code and product data sheetChecks size, test conditions, operating limits, and product revision
Vessel diameter and length, plus element countConfirms the 8-inch format and mechanical arrangement
TDS, temperature, pH, pressure, recovery, and permeate targetCompares models by process duty rather than a similar-sounding name
Quantity, project location, and required dateEstablishes availability, delivery, and quotation scope

Do not replace an element solely because “RE8040-BE” appears in a purchase request. Match the old label against the Toray brackish-water RO membrane range or the CSM RE8040-BE data sheet, then send the findings through the Watermart contact form. Drinking-water systems still require commissioning, sanitation, consumables records, representative sampling, and laboratory verification against applicable Indonesian standards.

Is the model SW30HRLE-440i or BW30HRLE-440i?

SW30HRLE-440i is not a FilmTec model code listed in the product documents on this site. The documented 440i model is BW30HRLE-440i for brackish-water RO; the documented seawater path is SW30HRLE-400. PT Watermart Perkasa checks the label, water analysis, vessel, pressure, and permeate target before quotation.

Term on the requestDocumented modelDuty and initial checks
“SW30HRLE-440i”Not found as a model code in the local FilmTec documentsRequest a label photo and check whether BW30HRLE-440i or another SW30 model was intended
BW30HRLE-440i8-inch BWRO element, 440 ft² area, iLEC interlocking end capsBrackish water; match TDS, pressure, recovery, vessel, seals, interconnectors, and performance projection
SW30HRLE-4008-inch SWRO element, 400 ft² areaSeawater; match salinity, high pressure, staging, energy recovery, pretreatment, and concentrate disposal

BW30HRLE-440i and SW30HRLE-400 are not direct substitutes even though both use an 8-inch format. Use the FilmTec 4040/8040 BWRO page for brackish-water models and the FilmTec SW30 seawater page for desalination models, then match Codeline pressure vessels and skid components to the project data.

Why can BW30HRLE-440i and SW30HRLE-400 figures not be compared directly?

The two permeate-flow figures are not directly comparable because the data sheets use different test salinity, pressure, and recovery. BW30HRLE-440i is tested as a brackish-water element, while SW30HRLE-400 is tested with synthetic seawater at much higher pressure. Compare a projection at the same project feed and target rather than choosing the largest gpd figure.

Sources are the BW30HRLE-440i product data sheet and SW30HRLE-400 product data sheet, reviewed on 2 August 2026. These figures identify manufacturer test conditions; design still requires the water analysis, temperature, recovery, staging, vessel, pretreatment, pump, energy recovery for SWRO, and the actual permeate target.

How can a wrong 440i code be kept out of a purchase order?

Lock the element identity to reviewable evidence before requesting a price or issuing a purchase order. A request written as “SW30HRLE 440i” should be held until the brand, complete model code, brackish- or seawater duty, and vessel configuration are confirmed; do not correct the code from memory or a similar name.

  1. Photograph the complete old-element label, packaging, and vessel nameplate; make sure the code suffix and wet or dry condition are legible.
  2. Match the code to the current product data sheet, including area, spacer, end cap, test conditions, and operating limits.
  3. Put the feedwater duty, TDS or salinity, permeate target, recovery, pressure, element count, and elements per vessel on the quotation request.
  4. Require the quotation and purchase order to repeat the complete code, quantity, documents, seals or interconnectors, and installation and commissioning boundary.
  5. On receipt, match the label and packing list to the purchase order before opening packages or mixing elements with other stock.

If the label is illegible, send vessel photographs, element count, operating data, and purchase history through the Watermart contact form. The technical response should keep unresolved assumptions visible until the product identity is supported by evidence.

What does the official FilmTec SW30HRLE-400 data sheet state?

The FilmTec SW30HRLE-400 product data sheet, Form No. 45-D00967-en Rev. 7 dated November 2024, lists 400 ft² (37 m²) active area, 7,500 gpd (28 m³/day) permeate flow, 92% stabilized boron rejection, 99.8% stabilized salt rejection, and 99.65% minimum salt rejection.

Those values use 32,000 ppm NaCl, 5 ppm boron, 800 psi (55 bar), 25°C, pH 8, and 8% recovery for one element. Manufacturer data do not guarantee site flow, rejection, pressure, energy use, or permeate quality. A projection must use the actual water analysis, temperature, salinity, recovery target, element count, staging, pressure drop, fouling and scaling risk, pretreatment design, and concentrate-disposal route.

Rev. 7 data-sheet limitListed value
Maximum operating temperature45°C; the document note limits continuous operation above pH 10 to 35°C
Maximum operating pressure1,200 psi (83 bar)
Maximum pressure drop15 psi (1.0 bar) per element; 50 psi (3.5 bar) per vessel with at least four elements
pH range2-11 for continuous operation; 1-13 for 30-minute short-term cleaning
Feed and oxidantMaximum SDI 5; free-chlorine tolerance below 0.1 ppm

Maximum values are product limits in the document, not design setpoints. Pressure, flux, recovery, feed and permeate flow, vessel, pump, piping, safety instruments, and start-up procedure must still be established for the actual system.

Buyer decisionData that must match

Compare another SW30 modelElement size, active area, spacer, test basis, rejection, permeate target, and operating limits from current data-sheet revisions

Use the dedicated FilmTec SW30 page for model comparisons. Match the element to Codeline pressure vessels, filter cartridges, and dosing pumps, then send the project data through the Watermart contact form.

When should a fouling-resistant RO membrane be considered?

Consider a fouling-resistant grade when operating evidence shows a fouling-prone feed and suitable pretreatment still leaves a risk that fits the product limits. The label is not a reason to skip root-cause analysis: review pressure drop, normalized permeate flow, salt passage, SDI, turbidity, organics, microbiology, scaling, oxidants, and cleaning history together.

Watermart content documents CSM FEn/FLR series and Toray TLF-400DG paths. These codes are not automatic replacements for an installed element; compare the CSM RE8040-FEn technical sheet and Toray membrane choices using the document revision available at procurement.

Does a fouling-resistant membrane replace pretreatment?

No. A fouling-resistant grade still requires pretreatment, operation within product limits, monitoring, and data-based cleaning. Installing new elements without addressing solids, organics, microbiology, scaling, oxidants, flow distribution, or CIP practice can repeat the same problem.

Which Toray membrane range should a buyer compare after reviewing the risk?

Start with the process and water quality, then choose the appropriate membrane family. BWRO, SWRO, and UF have different duties; a similar-looking element format does not establish pressure, rejection, flux, sanitation, or vessel compatibility.

SWRO membrane price depends on water data and supply scope

SWRO membrane elements for seawater desalination systems

SWRO membrane price in Indonesia depends on model, element size, quantity, feedwater salinity, permeate target, design pressure, location, and supply scope. PT Watermart Perkasa compares project requirements with DuPont FilmTec and Toray seawater RO membrane options after reviewing the water analysis, vessel, pretreatment, recovery, and operating conditions.

Element price alone does not represent the cost of an SWRO system. Pretreatment, filter cartridges, pressure vessels, high-pressure pumps, dosing, energy recovery, instruments, installation, commissioning, and testing may be inside or outside a quotation. Ask each supplier to state the supply boundary so pricing can be compared fairly.

SWRO price factorInformation to provide
Model and element sizeBrand/series, complete model code, 4040 or 8040 size, and wet/dry condition
Feedwater and targetSalinity/TDS, temperature, pH, ion analysis, and target permeate flow and quality

Buyer questions about TM720D-400 and RO membranes

Are Toray TM720D-400 and TM720D-440 direct replacements for each other?

Not automatically. They list different active areas, feed spacers, and test flows. Verify the existing-element label, vessel, interconnector, pressure drop, water quality, flux, recovery, pretreatment, and permeate target before changing models.

Is Toray RE8040-BE the correct model code?

Not according to the product documents available on this site. RE8040-BE is listed in the CSM range, while Toray uses other code families. Hold the price request until the label photo, brand, complete code, 8-inch vessel, water data, and permeate target establish the element actually required.

Is SW30HRLE-440i a FilmTec seawater model?

No SW30HRLE-440i code appears in the FilmTec documents available on this site. The documented 440i code is BW30HRLE-440i for brackish water, while SW30HRLE-400 is a seawater model. Verify the label, packaging, and current product data sheet before selecting or replacing an element.

Is SW30HRLE-400 the right element for brackish water?

SW30HRLE-400 is designed for seawater desalination at medium to high feed salinity. For brackish feed, compare BWRO models using the same water analysis and permeate target; do not choose an SWRO element only because its 8040 format fits the vessel.

Is the 7,500 gpd capacity guaranteed on site?

No. The 7,500 gpd value is a one-element test result under the stated manufacturer conditions. Actual flow changes with salinity, temperature, pressure, recovery, staging, fouling, scaling, pressure drop, and pretreatment, so it requires projection and commissioning verification.

What minimum data is required for an SWRO membrane price?

Send the requested brand or model code, element size and quantity, water analysis including salinity/TDS and temperature, permeate flow and quality target, recovery, pressure, vessel configuration, pretreatment, project location, and required date. For replacements, include an old element label photo and operating records.

Can a BWRO membrane replace an SWRO membrane?

Do not substitute BWRO and SWRO elements merely because their dimensions match. Salinity, pressure, target rejection, permeate, recovery, spacer, vessel, and operating limits must be checked with the relevant datasheet and design projection.

Does the price include pressure vessels and commissioning?

Not necessarily. Ask the quotation to separate membrane elements, seals or interconnectors, pressure vessels, installation, flushing, commissioning, testing, and delivery. A written supply boundary makes price comparisons more accurate.

Does an SWRO system automatically produce drinking water?

No. The system must meet applicable Indonesian drinking-water requirements and include commissioning, sanitation, consumables logs, representative sampling, and laboratory verification of the treated water. Membrane selection alone does not prove drinking-water compliance.

No. The 1,200 psi figure in the data sheet is an element maximum, not a normal setpoint or a rating for the complete skid. Working pressure must follow salinity, temperature, permeate and recovery targets, element arrangement, pressure drop, and the ratings of the vessel, pump, piping, valves, and safety instruments.
