The 8040 RO Membrane Toray TM720D-400 is one of the most advanced industrial reverse osmosis membranes used in India for high TDS water treatment and large-scale RO plants.

Industrial water treatment requires precision, durability, and continuous performance. When dealing with high TDS borewell water, harsh industrial wastewater, or complex municipal supplies, standard filtration systems simply fall short. This is where investing in the right industrial RO membrane 8040 size becomes essential for consistent, efficient, and uninterrupted purification.

Whether you are operating a pharmaceutical plant, a food processing unit, a chemical facility, or a large commercial setup, selecting a premium membrane directly impacts your system's output efficiency, minimizes operational downtime, and significantly lowers long-term maintenance costs.

Quick Overview 

The 8040 RO Membrane Toray TM720D-400 is a high-capacity industrial reverse osmosis membrane designed for large-scale water purification systems. It delivers an 11,000 GPD output with up to 99.8% salt rejection, making it widely used in Indian industries for treating high TDS water in heavy-duty industrial RO plants.

Best use cases: Boiler feed water systems, pharmaceuticals, food & beverage processing, textile industries, and municipal water treatment.

What is an 8040 RO Membrane?

In the commercial water treatment sector, "8040" dictates the standardized dimensions of the membrane element:

• 80 = 8-inch diameter

• 40 = 40-inch length

This configuration makes it the standard industrial RO membrane 8 inch size, universally relied upon for high-capacity RO systems. Due to its massive active surface area, it can treat thousands of gallons of water daily while efficiently removing dissolved salts, heavy metals, organic impurities, and severe high TDS contaminants.

• A longer, more reliable operational lifespan

• Superior salt rejection performance over time

Toray is one of the world’s most trusted membrane manufacturers, with decades of experience in reverse osmosis technology. Its membranes are widely used in critical industries such as pharmaceuticals, semiconductor manufacturing, power generation, and municipal water treatment plants where consistent water purity is essential for operational safety and compliance.

Technical Specifications of TM720D-400

Understanding the reverse osmosis membrane 8040 specification is critical for accurate plant design, scaling, and daily optimization:

• Active Membrane Area: 400 ft² (37 m²)

• Permeate Flow Rate: 11,000 GPD (41.6 m³/day)

• Nominal Salt Rejection: 99.80% (Minimum 99.65%)

• Membrane Type: Cross-linked fully aromatic polyamide composite

• Feed Spacer Thickness: 34 mil (Advanced anti-fouling design)

• Maximum Operating Pressure: Up to 600 psi

• Maximum Feed Water Temperature: Up to 45°C

• pH Range (Continuous Operation): 2–11

• pH Range (Chemical Cleaning): 1–13

How the Toray RO Membrane Works

The RO element TM720D-400 operates on the highly efficient principle of reverse osmosis. Here is the step-by-step process:

1. Pressurization: High-pressure industrial pumps force contaminated feed water into the membrane housing.

2. Filtration: The semi-permeable polyamide membrane allows only pure water molecules to pass through its microscopic pores.

3. Rejection: Dissolved salts, heavy metals, and suspended impurities are blocked.

4. Collection & Discharge: Pure water (permeate) is collected for use, while the concentrated waste (brine) is safely discharged.

This process guarantees up to 99.8% purification efficiency on a continuous cycle.

Applications in Indian Industries

India’s industrial manufacturing hubs—such as Delhi NCR, Gurugram, Noida, Mumbai, Chennai, and Ahmedabad—face severe geographic water quality challenges, particularly scaling issues and extremely high TDS groundwater.

The high flow RO membrane 8040 size is expertly tailored to conquer these conditions across various sectors:

• Industrial Utility: Boiler feed water systems, cooling tower makeup, and Zero Liquid Discharge (ZLD) plants.

• Manufacturing & Processing: Pharmaceutical formulation, chemical processing units, and textile dyeing/recovery.

• Commercial Infrastructure: Large-scale purification for hospitals, premium hotels, and extensive residential complexes.

• Consumables: Food and beverage packaging plants requiring strict hygiene and taste consistency.

It is commonly used along with RO Pre-Treatment Systems, Water Softener Systems, and High Pressure Pump Systems for optimal performance

Benefits of Industrial RO Membrane 8040

•  Massive Output: High efficiency with an 11,000 GPD yield.

• Slower Degradation: Maintains peak salt rejection longer, making it superior for continuous industrial operation.

Industrial RO Membrane Price in India (2026 Guide)

The industrial RO membrane price in India depends on brand, capacity, and salt rejection efficiency. Premium membranes like the Toray TM720D-400 8040 RO membrane are priced higher due to advanced Japanese engineering, high flow capacity, and longer operational life.

However, industries prefer premium membranes because they:

• Reduce maintenance cost
• Increase plant uptime
• Improve energy efficiency
• Deliver stable output quality

This makes them more cost-effective in long-term industrial operations.

Maintenance & Lifespan Guide

To guarantee maximum performance and protect your investment:

•  Maintain an SDI (Silt Density Index) below 5 using proper pre-filtration.

•  Install Water Softener Systems for strict hardness control.

•  Utilize comprehensive RO Pre-Treatment Systems (multimedia and active carbon filters).

•  Ensure feed water chlorine levels remain strictly below 0.1 ppm.

•  Perform CIP cleaning protocols as soon as normalized performance drops by 10–15%.

With proper pre-treatment and maintenance, this membrane ensures a robust lifespan of 2–3 years or more.
