Toray 8040 Membrane – Specs & Price| Romegamart
RO membranes are the heart of any reverse osmosis (RO) system, and the Toray 8040 is among the most trusted in industrial and commercial setups. In this guide, we’ll dive deep into the specifications, performance, pricing dynamics, and how you can source the best deals in India. We’ll also highlight why Romegamart is a key marketplace for buying genuine RO components.
What Is the Toray 8040 Membrane?
-
“8040” refers to an 8-inch diameter, 40-inch long spiral wound RO membrane.
-
Toray is a globally renowned brand in membrane technology. Romegamart
-
In industrial RO plants, 8040 membranes are preferred when high volume and reliability are required.
-
For example, Romegamart offers the Toray TM710 8040 membrane, capable of handling up to 4,000 TDS in industrial applications. Romegamart
Key Specifications
Here are typical specifications and performance metrics for Toray 8040 membranes (actual values may vary by model variant):
| Parameter | Typical Value / Range |
|---|---|
| Type | Polyamide Thin Film Composite (TFC) or equivalent |
| Diameter × Length | 8" × 40" |
| Salt Rejection | ~99.7 % (depending on model) |
| Maximum Operating Pressure | ~600 psi (≈ 4.1 MPa) |
| Operating pH Range | ~2–11 (continuous) |
| Temperature Range | Up to ~45 °C or 113 °F |
| Chlorine Tolerance | Very low – free chlorine < 0.1 ppm usually required |
| Feed Water SDI / Fouling Tolerance | Pre-treatment usually mandatory |
| Input TDS Handling | Some variants handle up to 4,000 TDS (e.g. TM710 8040) Romegamart |
Note: Always check the exact model number (e.g. TM710, TM720, TM720D, etc.), since variants differ in rejection rate, fouling resistance, and design.
How to Choose the Right Variant
When selecting a Toray 8040 membrane, consider:
-
Feed water TDS & quality — high TDS demands more robust variants.
-
Flow / capacity requirements — match membrane flux to system demand.
-
Fouling & scaling potential — choose anti-fouling designs if water has high turbidity, hardness, or organics.
-
Long-term reliability & maintenance — going for slightly higher grade can save in lifecycle cost.

Monitor flux decline and salt rejection trends
-
Replace when performance drops significantly
Buying Tips in India
-
Verify seller credentials and authenticity
-
Request datasheet & performance certificates
-
Ask for warranty & replacement terms
-
Use platforms that aggregate multiple sellers (e.g. Romegamart)
-
Compare landed cost (product + freight + duty)
-
Bulk orders often yield better margins
Romegamart is becoming a favored platform because of its wide product catalog, verified sellers, and “bulk / wholesale” negotiation features. Romegamart+1
FAQs
Q1: Can I use Toray 8040 in domestic RO systems?
Generally not. 8040 is overkill for household use in terms of size, flow, and pressure. Domestic systems normally use smaller membranes (e.g. 4040 or 4040 variants).
Q2: How long does a Toray 8040 membrane last?
With proper maintenance and feed water quality control, a lifespan of 3–5 years is common. Fouling, poor pre-treatment, or chlorine exposure can shorten it.
Q3: Is the performance same across all Toray 8040 variants?
No. Variants like “D”, “V”, “FR” etc. denote differences in fouling resistance, chlorination tolerance, or design tweaks. Always check datasheet.
Q4: How much pressure is needed for 8040 membranes?
Typical operating pressure is ~600 psi (4.1 MPa) for full performance, though exact design may vary. clearionexchange.in
Q5: Does Romegamart deliver across India?
Yes — Romegamart lists industrial RO components including Toray membranes with pan-India shipping & verified seller listings. Romegamart+1
Q6: What is “Get Wholesale Price” on Romegamart?
It’s a feature allowing bulk buyers to negotiate or request discount pricing for bulk orders directly from sellers. Romegamart
Conclusion
The Toray 8040 membrane is a robust workhorse for industrial and commercial RO systems, combining strong salt rejection, durability, and wide availability in India. While the upfront cost can be significant, the total cost of ownership becomes favorable when you maintain it correctly.
If you're sourcing it in India, a platform like Romegamart offers multiple sellers, transparent specs, and bulk‐price negotiation features — making it a smart stop for RO system integrators, dealers, and plant operators.
