Our Membrane Portfolio
RO (Reverse Osmosis) Membranes
5
99.9 % salt-rejection spiral-wound elements
Models for low-, standard-, and high-pressure applications (60 – 1 200 psi)
Certified for drinking-water contact and industrial process water
Ideal for domestic under-sink units, bottled-water plants, and power-plant boilers
Nano-Filtration (NF) Membranes
Selective removal of divalent ions—perfect for water softening and partial desalination
Retains beneficial calcium and magnesium while reducing hardness and colour
Reduces operating pressure versus full RO, saving
Ultrafiltration (UF) Membranes
Hollow-fibre design filters bacteria, viruses, and suspended solids down to 0.02 µm
Robust PVDF chemistry for high pH and chemical resistance
Widely used in beverage clarification, effluent polishing, and pretreatment before RO
Micro-Filtration (MF) Membranes
1
1 µm pore size for turbidity reduction and oil-water separation
Stable at Low Pressures (10
30 psi) with high flux rates
Excellent as a stand-alone filter or as the first barrier in multistage systems
Custom & Speciality Membranes
High-pressure seawater RO elements (up to 1 200 psi)
Anti-fouling coatings for challenging feed waters rich in organics
Round and flat-sheet formats for OEM integration
Industries We Serve
Residential Drinking-Water Appliances
compact, quiet, mineral-balanced output
Pharmaceuticals & Food-and-Beverage
USP-grade purified water, CIP-friendly modules
Textiles & Dyeing
colour and TDS control for zero-liquid-discharge (ZLD) goals
Agriculture & Hydroponics
fertigation-ready water that boosts yield without salt stress
Why Choose Greenly Membranes?
9 % Rejection, Pure Taste
Advanced thin-film composite layers strip out salts, microbes, pesticides, and heavy metals, producing water that meets WHO standards.
Energy-Smart Engineering
Low-pressure options and high-flux designs cut pump power—ideal for solar or generator-run sites.
Long Service Life
PVDF and polyamide sheets resist chlorine shock, fouling, and pressure cycling, delivering 3–5 years of dependable performance.
Minimal Maintenance
Smooth membrane surfaces slow down biofilm growth; simple back-flush or chemical clean restores full flow in minutes.
Cost-Effective Ownership
Competitive upfront pricing plus extended life cycles mean lowest rupees-per-litre over the membrane’s lifespan.
How Our Membranes Work
Feed water is forced across a semi-permeable barrier. Pure H₂O molecules pass through, while dissolved salts, pathogens, and organic contaminants are rejected to drain. The result: safe, flavour-neutral water for homes, factories, and farms.
Technical Snapshot
| Membrane Type | Typical Pressure | Salt Rejection | Relative Flow |
|---|---|---|---|
| RO | 60 – 100 psi (domestic) / 250 – 1 200 psi (SWRO) | 99.5 – 99.9 % | Medium |
| NF | 70 – 120 psi | 50 – 90 % (divalent) | Medium |
| UF | 30 – 50 psi | — | High |
| MF | 10 – 30 psi | — | High |
Choose with confidence
Choosing the right filtration systems
- Identify the problem: turbidity, iron, smell, colour or chlorine.
- Match the filter size to flow rate (m³/hour) rather than tank size.
- Plan backwash water and a drain point near the filter.
- Use filtration ahead of RO or softeners to protect them.
- Agree a media replacement schedule at installation.

More in Filtration Systems
What is a cartridge filter housing used for?
It seals and protects the filter element, ensuring leak-free operation and easy change-out while withstanding system pressure.
Are Greenly housings compatible with standard 10-inch filters?
Yes. Our housings accept 10 × 2.5 in and 20 × 2.5 in industry-standard cartridges with no adapters.
Can cartridge filters be reused?
Sediment and pleated filters can be rinsed once or twice. Carbon block, resin, and HEPA filters should be replaced after their rated life.
Do you supply filters for salt-water aquariums?
Absolutely—choose our marine-grade pleated cartridges designed for saline environments to avoid corrosion.
Can you customise housings for special pressures or chemicals?
Yes. We engineer custom cartridge filter solutions—including exotic polymers and stainless-steel bodies—to match your exact application.
Which filter do I need for borewell water?
Most borewell water needs a sand or multi-grade filter for suspended solids, and an iron removal filter if iron is present. A water test tells us which stages are needed.
What does an activated carbon filter remove?
Carbon filters reduce chlorine, odour, colour and many organic compounds. They are often used after a sand filter and before RO or softening.
How often should filter media be replaced?
Sand media lasts longer than carbon. Replacement depends on water quality and backwash practice; we share a schedule when the filter is installed.
What is backwashing?
Backwashing reverses the flow through the filter to lift and flush out trapped dirt. Regular backwashing keeps pressure drop low and media working.
Can you build filters for agriculture and industry?
Yes. We build sand filters for drip irrigation, industrial process water and RO pre-treatment in sizes to suit the flow.
