Filtration that stays clean.
PureMem builds nanocomposite filtration membranes with silica nanoparticles and a nano-silver coating that resist fouling, so water and wastewater treatment runs longer with less cleaning.
The problem
Fouling is the hidden cost of membrane filtration.
Membranes clog over time, cutting flow, raising energy use and forcing frequent cleaning or replacement. Industrial wastewater, such as dairy effluent, is especially demanding.

How it works
How it works
A clear path from data to decision.
Blend
Amino-functionalised nano-silica is added to a PES/PVP polymer mix.
Cast
The nanocomposite membrane is formed.
Coat
A nano-silver/PVA layer is applied to boost anti-fouling.
Filter
Membranes treat wastewater with high separation and easy recovery.
Product
What makes it different.
Every feature is grounded in the founding research.
Super anti-fouling
99.5% flux recovery after fouling tests.
High separation
Up to 99.7% of whey separated from the feed.
Less maintenance
Reduced backwash needs and longer service life.
Nano-engineered
1.5% nano-silica gave optimum performance.
Who it's for
Who it's for.
Dairy & food industry

Water treatment plants
Longer-lasting membranes, lower costs.
Industrial facilities
Reuse water with reliable filtration.
The research
Built on peer-reviewed research.
- Antifouling membranes made by encapsulating amino-functionalised nano-silica in PES/PVP.
- Membranes modified with a nano-Ag/PVP coating layer.
- Optimal M3 (1.5% nano-silica) separated 90% of whey at 238 L/m²·h.
- Coated M3S raised separation to 99.7% with a flux recovery ratio of 99.5%.

FAQ
Questions we hear often.
What can PureMem treat?
It has been tested on dairy-type wastewater and is designed for demanding water treatment uses.
Why does anti-fouling matter?
Less fouling means steadier flow, less cleaning and lower operating costs.
Is this a finished commercial product?
It is a research-based student startup moving from validated prototype toward pilots with real users.
Can we partner or run a pilot?
Yes. We are looking for organisations willing to test the solution in real conditions and share feedback.
