Our Membrane Portfolio
RO (Reverse Osmosis) Membranes
99.5 – 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 up to 20 % energy
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
0.1 – 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

Why Choose Greenly Membranes?
99.9 % 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 by up to 15 %—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 |

| NF | 70 – 120 psi | 50 – 90 % (divalent) | Medium |
| UF | 30 – 50 psi | — | High |
| MF | 10 – 30 psi | — | High |
Frequently Asked Questions
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.
