1. Introduction: Why RO Housing Matters in Industrial Filtration

One of the most crucial components of any RO water purification system—especially at the industrial level—is the RO housing, also known as membrane housing. Whether you're running a 500 LPH commercial plant or a 10,000 LPH industrial RO unit, the durability, pressure handling capacity, and compatibility of the housing directly affect water output quality and system lifespan.

The industrial water filtration market in India has grown significantly, and so has the demand for high-grade RO membrane housings. Yet, most buyers struggle to find reliable and transparent information about RO housing prices, quality standards, and how to choose the right model. In this blog, we break down everything you need to know.

2. What is RO Housing in Water Purifiers?

RO housing is a pressure vessel that encloses the RO membrane in a reverse osmosis system. In industrial systems, the housing is engineered to withstand high operating pressures—often ranging between 300–1200 PSI—and is typically made of high-strength plastic (PP), stainless steel (SS 304 or SS 316), or FRP (Fiber Reinforced Plastic).

Its primary roles:

• Hold the membrane securely in place

• Ensure water flows under high pressure for filtration

• Prevent leakage and contamination

• Allow safe removal and replacement of membranes

3. Types of RO Housing Units Available

Industrial buyers can choose from a variety of RO housing units, each suited for different capacities and operating conditions. The most common types include:

a. FRP RO Housing

• Material: Fiber Reinforced Plastic

• Pressure Range: 300–600 PSI

• Common Sizes: 4040, 8040

• Application: Light to medium industrial setups

b. Stainless Steel RO Housing

• Material: SS 304 or SS 316

• Pressure Range: Up to 1000 PSI

• Rust & corrosion-resistant

• Ideal for pharmaceutical and food-grade applications

c. Polypropylene (PP) Membrane Housing

• Mostly used in domestic but some industrial variants are available

• Lightweight, lower pressure resistance

• Budget-friendly option for low-pressure setups

4. Factors Affecting RO Housing Price

1. Material Used

• SS 316 is more expensive than SS 304 due to higher corrosion resistance

• FRP is cheaper but ideal for medium-pressure systems

• PP is cheapest but limited in industrial applications

2. Housing Size

• 4040 (40 inches length × 4 inches diameter) vs 8040 (40 inches × 8 inches)

• Larger housings require more raw material, hence higher prices

3. Pressure Rating

• High-pressure housings (1000+ PSI) are costlier

• Thicker walls and heavy-duty threads increase durability and cost

4. End Cap & Port Design

• Side port vs end port

• Stainless steel clamp vs plastic clamp fittings

• Multi-port design may increase cost

5. Brand & Certification

• Certified manufacturers like Dow, Ion Exchange, Netsol, or Hindustan Engineers charge a premium

• BIS/NSF certifications may also increase price due to compliance costs

6. Comparison: 10 Inch vs 8040 Industrial Membrane Housing

While 10-inch housings are commonly found in domestic systems, industrial buyers focus on 4040 and 8040 housing dimensions.

Clearly, the 8040 housing is the preferred choice in medium to large-scale RO plants.

9. Tips to Choose the Right RO Housing for Your System

Before purchasing, here are a few expert tips:

✔️ Check Operating Pressure:

Always match the housing with the pressure capacity of your RO system. Overpressure can lead to leakage or burst.

✔️ Verify Membrane Compatibility:

Some membranes only fit specific designs (side port vs end port). Ask the seller or refer to the membrane specs.

✔️ Consider Future Scaling:

Buy a housing that supports additional pressure or flow capacity if you plan to expand plant output.

✔️ Look for Warranty & Certifications:

Ensure the housing comes with at least a 1-year warranty. Also, look for BIS or NSF-compliant models for sensitive applications.

10. Conclusion: Invest Smartly in RO Housing
