Ultrafiltration (UF) Membrane Technology

Ultrafiltration is a pressure-driven membrane separation process that uses semi-permeable membranes with pore sizes between 0.1 and 0.001 microns — small enough to physically block bacteria, viruses, and other microorganisms while allowing clean water molecules to pass through.

Unlike reverse osmosis, UF operates at low pressure without chemicals, wastes no water, and requires no electricity — making it the ideal technology for Sri Lanka's varied conditions.

Our membranes are manufactured by Synopex Co. Ltd in South Korea, certified under ISO 9001 and ISO 14001, and further enhanced with nano-technology contributed by Sunbola Technology.

Understanding Water Quality

pH Value

Acidity & Alkalinity Scale

pH measures how acidic or basic water is on a scale of 0 to 14. Neutral water is 7. The ideal pH range for drinking water is 6 to 8.5.

0 Acidic7 Neutral14 Alkaline
✓ Ideal Drinking Range: pH 6 – 8.5

pH below 6.5 indicates acidic, corrosive water containing toxic metals. pH above 8.5 indicates hard water that causes scaling and health issues.

TDS — Total Dissolved Solids

Mineral & Chemical Content

TDS measures dissolved minerals, chemicals, and fertilizers in water. High TDS causes bad taste, pipe scaling, and health risks.

Why Clean Water Matters Here

103 River Basins
335km Mahaweli River (Largest)
30% Safe Water Demand Met
70% Rely on Unsafe Sources

Chronic Kidney Disease of Unknown Etiology (CKDU) has been strongly linked to contaminated drinking water in Sri Lanka's agricultural regions — making effective water purification not a luxury, but a public health necessity.

Filtration Science

Filtration Mechanisms

01

Depth Filtration

Uses a thick, porous medium with wide, irregular channels. Particles are trapped throughout the entire depth of the filter matrix, not just on the surface. Ideal for high turbidity water with large particle loads.

Wide pore size · High volume · Pre-treatment stage

02

Surface Filtration

Operates through a very precisely sized membrane layer. Contaminants larger than the pore size are blocked entirely at the membrane surface. This enables high-precision removal of bacteria, viruses, and fine particles.

Narrow pore size · High precision · Absolute barrier
