DuPont TapTec LC HF‑4040 vs FilmTec BW30
DuPont TapTec LC HF-4040 is a 4-inch commercial RO membrane in Indonesia. Compare test basis, feedwater, vessel, pretreatment, FilmTec BW30 models, and price.
DuPont TapTec LC HF-4040 is a 4-inch commercial RO membrane, not an automatic FilmTec BW30 substitute merely because both use a 4040 format. PT Watermart Perkasa compares the test basis, feedwater, permeate target, recovery, pressure, pretreatment, vessel, quantity, and supply boundary before quoting.
Updated 3 August 2026: the position of TapTec LC HF-4040 against FilmTec BW30, the test basis, and the 4-inch quotation path were clarified.
TapTec LC HF-4040 or FilmTec BW30 PRO-4040?
Choose TapTec LC HF-4040 or FilmTec BW30 PRO-4040 from process duty and a system projection, not from the shared 4040 name. The December 2022 TapTec data sheet lists 2,800 GPD average test flow and 99.0% stabilized salt rejection at 1,500 ppm NaCl, 150 psi, 25°C, pH 7, and 15% recovery; those values do not guarantee site production.
| Buyer path | When to review it | Evidence required before quotation |
|---|---|---|
| DuPont TapTec LC HF-4040 | A 4-inch commercial RO skid with suitable feedwater and capacity target | TapTec data sheet, label photo, TDS, temperature, permeate target, recovery, pressure, pretreatment, and vessel |
| FilmTec BW30 PRO-4040 | A 4-inch BWRO system selected from brackish-water data | Complete model code, wet/dry condition, water analysis, projection, spacer, seals, and operating history for replacement |
| FilmTec BW30 PRO-400 or another 8040 series | A nominal 8-inch vessel; not a mechanical alternative to a 4040 element | Vessel diameter and length, element count, flow target, pressure, staging, and interconnectors |
Use the DuPont TapTec LC HF-4040 data sheet for that model basis, then compare the FilmTec document current at procurement. For seawater, use the FilmTec SW30 range, not either BWRO path.
What information is needed for a FilmTec RO membrane price?
Compare prices only when quotations state the manufacturer, complete model code, element size, wet or dry condition, data-sheet revision, quantity, documents, lead time, delivery, and the same supply boundary. “4040 membrane” or “8040 membrane” is not a complete specification because same-size models can differ in active area, spacer, end cap, test conditions, rejection, and feedwater duty.
PT Watermart Perkasa requests the water analysis, permeate flow and quality target, recovery, pressure, temperature, vessel configuration, pretreatment, operating history, location, and schedule. These inputs select the BWRO model on this page or direct the buyer to the FilmTec SW30 seawater range and DuPont FilmTec membrane hub—not to a site-output promise based only on a data-sheet figure.
| Buying scenario | Evidence to send | Minimum quotation content |
|---|---|---|
| New BWRO skid | Water analysis, permeate target, recovery, pressure, staging, vessel, and pretreatment | Model code, quantity, projection basis, documents, delivery, and commissioning boundary |
| Element replacement | Label photo, old code, wet/dry condition, operating hours, normalized flow, salt passage, pressure drop, and CIP history | Model fit, seals/interconnectors, flushing, installation, and testing when included |
| Rapid price request | Size, code, quantity, location, and required date | Written assumptions, availability, lead time, tax/delivery basis, and technical exclusions |
How should the procurement cost of RO membranes be compared?
Compare the total cost to place the elements into operation, not only the membrane unit price. For each quotation, align the model code, quantity, currency, tax, delivery, seals and interconnectors, storage, removal, installation, flushing, commissioning, testing, and downtime responsibilities assigned to the supplier or buyer.
- Set one technical basis: complete model, wet or dry condition, quantity, document revision, vessel, and required date.
- Separate element cost from components, logistics, site work, and testing.
- Record exclusions and assumptions in the same comparison columns; do not treat a blank line as included scope.
- Check quotation validity, lead time, storage conditions, and who carries risk if installation is delayed.
- Before issuing a purchase order, ensure the acceptance criteria cover label checks, packaging condition, flushing, commissioning, and start-up data where those services are included.
Use Codeline pressure vessels, filter cartridges, and dosing pumps as a checklist of components that may sit outside the element price. A lower quote may not have a lower total cost when the supply boundary, schedule, or commissioning responsibility differs.
When should a FilmTec membrane be cleaned or replaced?
Do not replace a FilmTec membrane only because of operating age or a decline in permeate flow. Review normalized permeate flow, normalized salt passage, differential pressure, feed quality, temperature, recovery, instruments, pretreatment, and the response to a correctly selected and executed cleaning. This evidence separates potentially cleanable fouling from damage or decline that requires replacement review.
| Operating finding | Check before buying new elements |
|---|---|
| Permeate flow declines | Normalize for temperature, pressure, salinity, and recovery; check flow-meter calibration and any production-demand change |
| Salt passage increases | Verify the conductivity meter, sampling, seals, interconnectors, mechanical leakage, oxidant exposure, and cleaning history |
| Differential pressure rises | Check cartridge filtration, solids, biofouling or deposits, flow distribution, and vessel pressure limits |
| Performance does not recover after cleaning | Confirm the procedure matched the deposit evidence and product limits, the fouling cause was addressed, and before/after data are comparable |
| Physical damage or out-of-limit exposure is suspected | Do not assume another cleaning is sufficient; document the event and request technical review before selecting a replacement |
For a replacement quotation, send the operating trend and cleaning history with the model code and element count. The team can review paths on the DuPont FilmTec membrane hub and the pretreatment components without promising that new elements will correct an unresolved root cause.
How do low-energy FilmTec RO membranes reduce pressure?
For suitable feedwater and permeate targets, FilmTec BW30HRLE-440 and 440i are designed to deliver flux at a lower test pressure than BW30 PRO-400. DuPont’s product data sheets describe both BW30HRLE models as offering good salt rejection at 33% lower pressure. That manufacturer statement is not a site energy-saving guarantee: pump power still depends on TDS, temperature, fouling, recovery, pressure drop, piping, pump efficiency, and element count.
| 8-inch model | Manufacturer test data | Procurement distinction |
|---|---|---|
| BW30HRLE-440 | 440 ft²; 12,650 gpd (48 m³/day); 99.3% stabilized rejection at 2,000 ppm NaCl, 150 psi, 25°C, pH 8, and 15% recovery | Standard end cap; confirm vessel, interconnector, seal, and 28-mil spacer |
| BW30HRLE-440i | Same listed nominal values as the 440 on its stated test basis | iLEC interlocking end caps; do not assume the connection arrangement matches a standard end cap |
| BW30 PRO-400 | 400 ft²; 11,000 gpd (42 m³/day); 99.6% stabilized rejection at 2,000 ppm NaCl, 225 psi, 25°C, pH 8, and 15% recovery | High-rejection comparison basis; not an automatic BW30HRLE substitute |
These documents were reviewed on 30 July 2026. Compare the revisions current at procurement, then run a projection with the actual water analysis and skid configuration because the nominal figures come from different test conditions.
Which FilmTec Brackish-Water RO Membrane Fits the Project?
For a nominal 8-inch vessel, use FilmTec BW30 PRO-400 as a high-rejection comparison against the low-energy BW30HRLE range; match the complete old label, elements per vessel, feed spacer, interconnectors, seals, wet or dry condition, and design data. A shared diameter does not make BW30-400, BW30 PRO-400, BW30HRLE-440/440i, or EcoPro-440i automatically interchangeable.
The FilmTec BW30 PRO-400 product data sheet, Rev. 4 dated November 2024, lists 400 ft² (37 m²) active area, 11,000 gpd (42 m³/day) permeate flow, and 99.6% stabilized salt rejection at 2,000 ppm NaCl, 225 psi, 25°C, pH 8, and 15% recovery. These figures compare elements on the manufacturer’s test basis; they do not guarantee site flow or permeate quality. A project projection must still use the actual water analysis, temperature, pressure, recovery, pretreatment, element count, and vessel arrangement.
| Requirement | Initial options on this page | Check before purchase |
|---|---|---|
| 8-inch vessel for industrial BWRO | BW30 PRO-400 or another projected 8-inch model | Water analysis, permeate target, pressure, recovery, spacer, elements per vessel, and pretreatment |
| Lower-energy target | BW30HRLE-440 or BW30HRLE-440i | Test conditions, feed quality, performance projection, vessel, seals, and interconnectors |
| Larger-area model | EcoPro-440i | Membrane area, spacer, test conditions, pretreatment, and permeate target |
| Existing-element replacement | FilmTec code matched to the old label and configuration | Label photo, operating/CIP history, pressure drop, permeate, salt passage, and replacement reason |
| Nominal 4-inch vessel | BW30 PRO-4040, not PRO-400 | Vessel diameter/length, target flow, pressure, old label, and start-up procedure |
For seawater, tap-water, or nanofiltration choices, use the DuPont FilmTec membrane hub or FilmTec SW30 range. Send the shortlist, project data, quantity, location, and timing through the Watermart contact form so the quotation states the product code and supply boundary in writing.
What determines the FilmTec 8040 RO membrane price?
Compare 8040 membrane pricing only when the model code and supply scope are the same. FilmTec BW30 Pro 400, BW30-400, EcoPro-440i, and other 8-inch models are not interchangeable merely because their diameter is similar. Beyond quantity, a quotation may change with delivery condition, project location, required date, interconnectors, seals, and any removal, installation, flushing, commissioning, or testing work.
| Quotation factor | Information to provide |
|---|---|
| Element identity | Complete model code, label photo, and wet or dry condition |
| Quantity and vessel | Element count, 8-inch vessel length, and elements per vessel |
| Design data | TDS and water analysis, permeate flow, recovery, pressure, temperature, and pH |
| System condition | Pretreatment, cartridge filtration, fouling/scaling, and cleaning history |
| Supply scope | Elements only or seals, installation, flushing, commissioning, and testing |
| Delivery | Project location, required date, site access, and document requirements |
| Buyer requirement | Page or document to check |
|---|---|
| BW30 Pro 400 for an 8-inch vessel | BW30 Pro 400 product data sheet |
| BW30 Pro 4040 for a 4-inch vessel | BW30 Pro 4040 product data sheet |
| Other FilmTec series for seawater, tap water, or NF | DuPont FilmTec membrane hub |
| RO skid components | Codeline pressure vessels, filter cartridges, and dosing pumps |
These documents were reviewed on 29 July 2026. Use the product data sheet revision current at procurement and verify the design with manufacturer software or project calculations; nominal datasheet values do not guarantee site output.
What water and vessel data must match an 8040 membrane?
When replacing an 8040 element, compare the existing element label and 8-inch vessel configuration with the design data rather than using element size alone. Confirm the complete model code and applicable datasheet before purchase, because suitability depends on system arrangement and operating conditions.
| Information to provide | Why it is checked |
|---|---|
| Photo of the existing element label and model code | Confirms the exact product identity, including variant and delivery condition |
| Vessel diameter and length, plus number of elements | Confirms mechanical fit with the installed configuration |
| TDS, temperature, pH, permeate flow, recovery, and pressure | Assesses fit with the water conditions and operating design |
| Pretreatment, cartridge filtration, and fouling/scaling history | Identifies risks to resolve before installing a replacement element |
Filmtec EcoPro-440i
EcoPro-440i is a different model from BW30 Pro 400. Match membrane area, spacer, test conditions, permeate target, and operating limits in the product data sheet before considering it as an alternative.
Filmtec BW30-2540
BW30-2540 uses a different element format from BW30 Pro 400. Check vessel diameter, element length, design capacity, and the complete model code before replacement.
Filmtec BW30-400
BW30-400 and BW30 Pro 400 are not names to interchange without checking. Compare the label, datasheet, membrane area, spacer, and operating limits for the installed configuration.
Filmtec BW30-Pro-400
BW30 PRO-400 is the high-rejection comparison for an 8-inch vessel, while BW30HRLE represents the low-energy option. Field performance depends on water quality, temperature, pressure, recovery, element count, pretreatment, cleaning, and commissioning; the datasheet does not guarantee site permeate flow or quality.
Data to check for BW30 Pro 400
Confirm TDS, permeate flow, design recovery, operating pressure, elements per vessel, temperature, pH, and pretreatment conditions before selecting BW30 Pro 400. These data are needed to assess fit in an industrial system and to compare options with other DuPont FilmTec RO membranes.
Filmtec BW30HRLE-440
BW30HRLE-440 is a 440 ft² low-energy option with a 28-mil spacer and standard end cap. Match the test conditions, feed quality, energy target, vessel, seals, and interconnectors; do not replace BW30 Pro 400 solely because the element diameter matches.
Filmtec BW30HRLE-440i
BW30HRLE-440i uses iLEC interlocking end caps and lists 440 ft², a 28-mil spacer, and 12,650 gpd on its product-data-sheet test basis. Run a performance projection with project water data and confirm the vessel, seals, and element arrangement before procurement.
Filmtec BW30-PRO-4040
BW30-PRO-4040 is a 4-inch element for brackish-water RO. Check free-chlorine limits, storage condition, fouling, scaling, and pretreatment requirements in the product data sheet before specifying operation or replacement.
Filmtec BW30-PRO-4040 Dry
Match the dry variant to the complete model code, delivery condition, wetting procedure, and current start-up instructions. Do not assume wet and dry variants are interchangeable without checking the product documentation.
What should be checked when FilmTec membranes arrive?
On receipt, match the purchase order, element label, wet or dry condition, quantity, and listed components before opening packages or loading elements into vessels. A receiving check separates a model-code or shipping problem from an installation problem and creates a traceable record if the project team needs clarification.
- Photograph the product label, complete model code, lot or other stated identifier, and the condition of every package.
- Match element size, quantity, wet/dry condition, document revision, and certificates to the purchase order and packing list.
- Check for packaging damage, leakage, a wet-supplied element drying out, and the condition of seals, couplers, interconnectors, or other components explicitly included in scope.
- Record the receipt date and storage conditions; follow the handling, preservation, storage, wetting, and start-up instructions for the delivered code.
- Hold installation if identity or condition does not match, then send the evidence through the Watermart contact form before discarding packaging or mixing elements with other stock.
Questions to ask an RO membrane distributor
Why is there no single RO membrane price on this page?
One figure can mislead when the model, quantity, wet/dry condition, destination, procurement date, tax or delivery basis, seals, interconnectors, documents, and installation services differ. Provide a common basis so quotations separate element price from components, delivery, flushing, commissioning, and testing where included.
Is 4040 or 8040 alone a complete quotation description?
No. The quotation should state the manufacturer, complete model code, wet or dry condition, quantity, data-sheet revision, documents, lead time, delivery, and service boundary. A shared nominal size does not establish the same duty, spacer, end cap, test basis, or performance.
Does a low-energy label guarantee a lower electricity bill?
No. A low-energy label describes element performance on the manufacturer’s test basis, while system electricity use depends on actual operating pressure and flow, recovery, feed quality, temperature, fouling, pressure drop, pump efficiency, and vessel configuration. Compare projections at the same permeate target, then verify performance after commissioning.
How do BW30 Pro 4040 and BW30 Pro 400 differ?
BW30 Pro 4040 is a 4-inch format, while BW30 Pro 400 is used in an 8-inch vessel. Start with the installed vessel diameter and element arrangement, then match TDS, permeate target, recovery, pressure, temperature, and pretreatment. Verify the old element code and whether a wet or dry replacement is required before requesting a quotation.
Why check pretreatment when replacing an RO membrane?
Pretreatment affects the solids, foulants, and scaling risk reaching an RO element. Include the water analysis and the cartridge-filter, softener, or other pretreatment details so membrane selection and operation are not based only on the previous model.
What information is needed for a FilmTec membrane quotation?
Send the complete model code, quantity, label photo, wet or dry condition, TDS and water analysis, permeate target, recovery, pressure, vessel, project location, required date, and service boundary through the Watermart contact form. Availability, model revision, lead time, and supply scope are confirmed at quotation.
Does the membrane alone make water ready to drink?
No. The system must meet applicable Indonesian drinking-water requirements and include pretreatment, commissioning, sanitation, monitoring, consumables records, representative sampling, and laboratory verification of the treated water.
