UF membranes operate at low pressure (0.5–3 bar) and provide microbiological safety without changing the mineral composition of the water. That is why they are common in drinking water treatment, surface water pretreatment and SDI reduction ahead of reverse osmosis. With periodic backwashing and chemical cleaning (CEB/CIP), membrane life reaches 5–7 years.
