vishakha September 15, 2025

 


Water purification is a major concern in India, especially for industries, commercial setups, and municipalities. Among leading global membrane manufacturers, Hydranautics (a part of the Nitto Group) stands out as a reliable, high-performance brand. If you are considering purchasing a Hydranautics membrane in India, this post will help you with everything: pricing, authorised dealers and distributors, how to read the catalogue, and how to choose the right variant for your needs.

What is Hydranautics & Its India Presence

  • Hydranautics is a manufacturer of reverse osmosis (RO), nanofiltration (NF), ultrafiltration (UF), and microfiltration (MF) membranes, under the umbrella of Nitto Denko. (Romegamart).

  • In India, Hydranautics has an established presence. Their product brochures, specification sheets, and technical support are available through authorised channels. (Romegamart)

Hydranautics Membrane Catalogue — Key Models & Lines

If you’re looking to select a model, the Hydranautics membrane catalogue is your go-to source. Some of the major series and key features include:

Series / Line Use Case / Best Features
CPA (Composite Polyamide) Brackish water RO, high salt rejection, wide range; higher models like CPA5, CPA6, CPA7 offer very high rejection and improved tolerance. (Romegamart)
ESPA (Energy Saving Polyamide) Lower feed pressure required, good for large scale systems wanting energy efficiency. (Romegamart)
SWC Seawater RO (desalination) applications.
LFC / LD variants LD (“Low Differential”) variants reduce pressure requirement and help against fouling, especially useful when feed water quality isn’t ideal. 

Other product lines also cover ultrafiltration / MF (for upstream pretreatment), specialty membranes, etc. The Hydranautics website offers brochures and element specification sheets that list active area, rejection rates, pressure/temperature limits, dimensions (4040, 8040, etc.).

Understanding Sizes: 4040 vs 8040

  • 4040 refers to membrane modules that are 4 inches in diameter and 40 inches long. Typically used for moderate capacity or smaller plants.

  • 8040 refers to modules that are 8 inches in diameter and 40 inches long. Suited for industrial RO plants or higher capacity systems.

Choosing between 4040 vs 8040 affects cost, throughput, pressure requirement, and panel size. Make sure to check which size is offered in the catalogue section for the model you are considering. (Romegamart)

Hydranautics Membrane Price in India (2025 Estimates)

Prices of genuine Hydranautics membranes in India vary depending on the model, size, and seller. Here are some indicative ranges based on recent listings:

Model / Variant Size / Spec Approx Price*
Hydranautics CPA5LD / CPA3 8040 Industrial / Brackish Water ₹30,000 – ₹40,000+ per piece (Romegamart)
Hydranautics CPA2 / CPA3 4040 Lower capacity / smaller plant Less than 8040 variants; exact rate depends on vendor, feed water TDS & specs. (Often significantly lower, but still a premium product.)
SWC / Seawater variants, LD / MAX versions Larger area, higher pressure Typically higher than standard models; similar ballpark or more, depending on shipping, import costs, vendor overhead.

*These are approximate, in Indian rupees, as of mid-2025; actual price will depend on vendor, location (city), order size, model variant (LD, MAX, specialty), and taxes/shipping.

For example:

  • A Coimbatore-based supplier lists CPA3 / CPA2 8040 variants at around ₹41,890 per piece. (Romegamart)

  • A supplier in Ahmedabad has listings for CPA2, CPA3, CPA5LD 8040 in the ₹30,000-₹38,000 range. 

Hydranautics Membrane Dealers & Distributors in India

Since authenticity, warranty, and performance heavily depend on buying from authorised or reliable sellers, here are some known dealers / distributors:

Dealer / Distributor Location What They Offer / Notes
Watco India Pvt. Ltd. Delhi / New Delhi Offers Hydranautics membranes, including industrial 8040 units. (Romegamart)
Unitech Water Solution Ahmedabad, Gujarat Authorised (associate) dealer. Stocks 4040 & 8040 Hydranautics models. Offers CPA2, CPA3, CPA5LD, SWC, LFC etc. 
KM Aqua Tech Coimbatore, Tamil Nadu Lists CPA2 / CPA3 8040 variants with pricing. 
TradeIndia Suppliers Across India Multiple listings of Hydranautics membranes for industrial RO, general dealers. Can compare quotes. 

Before you finalize a dealer, check:

  • Whether they are authorised by Hydranautics / Nitto

  • Whether they provide full product catalogues and spec sheets

  • Warranty / after-sales support

  • Whether the membrane is genuine (packaging, serial number, performance certificate)

What Impacts the Price & Total Cost

When buying Hydranautics membranes in India, the sticker price is just one part of the cost. Other factors include:

  • Model variant (CPA, ESPA, etc.), whether it is an LD or MAX version

  • Size / format (4040 vs 8040)

  • Feed water TDS, hardness, fouling potential — more challenging water requires more pretreatment, which adds cost

  • Shipping / freight / customs / taxes — especially for imported variants or if shipping long distances

  • Installation, pretreatment, system design — pumps, housings, filters

  • Maintenance (cleaning, chemicals) and membrane lifespan

So, comparing just “price per membrane” without considering total cost of ownership can lead to poor choices.

How to Use the Hydranautics Membrane Catalogue

Here are tips on navigating the Hydranautics (India) product catalogue:

  1. Model family: Identify whether your requirement is for brackish water, seawater, or specialty (wastewater reuse, ultrapure, etc.).

  2. Size & format: Whether 4040 or 8040 etc.

  3. LD (Low Differential) or other advanced features: If energy cost is important, LD variants reduce required pressure.

  4. Operating limits: Temperature, pH range, maximum pressure, feed-water TDS.

  5. Active membrane area: Higher area reduces number of elements but increases size and sometimes cost.

  6. Salt rejection / permeate quality: You’ll find charts comparing how membranes perform under different conditions.

  7. Durability / fouling resistance: Look for variants with special feed spacers or coatings.

You can download PDF brochures / product specification sheets from the Hydranautics / Nitto website under Brochures / Knowledge Centre. ( Hydranautics CPA 3 Nitto 8040 Industrial RO Membrane)

Tips for Buyers in India

  • Always verify the model’s specs against the catalogue (salt rejection, TDS capacity, etc.).

  • Check for original packaging and serial numbers from Hydranautics / Nitto.

  • If needed, ask the dealer for test certificates showing performance (e.g. salt rejection / flux under specific conditions).

  • Ensure adequate pretreatment of feed water (filtration, removal of hardness/scaling agents, etc.) to protect the membrane.

  • Consider life-cycle cost, not just up-front price. Energy, maintenance, replacement etc. can dominate.
