Ultrafiltration

Illustration: Ultrafiltration

The problem

Ultrafiltration (UF) is membrane filtration with pore sizes of roughly 0.01–0.1 µm. A UF membrane removes suspended solids, colloids, bacteria and most viruses while keeping dissolved minerals. It is used for drinking water production, as pre-treatment for reverse osmosis, in the food industry and for water reuse.

Our solution

Together we determine your needs, supply suitable equipment or materials, install them and keep the system running with maintenance. We have 15 years of experience in water treatment and work across Estonia.

Price

Price depends on water quality, required capacity and installation scope. We prepare an exact quote after a water analysis or site details.

Service area

We are based in Tartu County (Rehepapi põik 3, Soinaste küla, Kambja vald) and mainly serve Tartu and Harju counties – Tartu, Tallinn and the surrounding areas. We also travel to sites anywhere in Estonia.

Frequently asked questions: Ultrafiltration

What is ultrafiltration?

Ultrafiltration is membrane filtration that removes suspended particles, colloids, bacteria and most viruses from water while leaving dissolved salts in the water.

How does ultrafiltration differ from reverse osmosis?

An ultrafiltration membrane has larger pores. It does not remove dissolved salts, but it operates at lower pressure and with lower energy consumption.

Where is ultrafiltration used?

It is used in drinking water treatment, as pretreatment for reverse osmosis, in water reuse and in the food and beverage industry.

How are UF membranes maintained?

The membranes are cleaned with automatic backwashing and periodic chemical cleaning. The maintenance interval depends on feed water quality.
