Ultrafiltration

Ultrafiltration (UF) is an advanced membrane-based water treatment process that removes suspended solids, bacteria, viruses, and high molecular weight compounds from water, producing crystal-clear, high-quality water. At RTW UK, we integrate UF technology into our systems to provide industries with reliable pre-treatment solutions, improve water reuse efficiency, and protect downstream processes like Reverse Osmosis (RO).

How Ultrafiltration Works

Ultrafiltration uses semi-permeable membranes with pore sizes typically around 0.01 microns. These membranes act as a physical barrier, allowing water and smaller molecules to pass through while retaining suspended particles, microorganisms, and other impurities.

Process Steps

Pre-Filtration

Water is pre-treated to remove larger debris and reduce the load on the UF membranes.

Membrane Filtration

The water is pushed through the UF membranes under low pressure, separating contaminants from the permeate (filtered water).

Backwashing

Regular cleaning of the membranes ensures consistent performance and longevity.

Key Features and Benefits of UF Technology

High Filtration Efficiency

Removes up to 99.99% of bacteria, viruses, and suspended solids.

Chemical-Free Process

Operates without the need for chemicals, ensuring an environmentally friendly solution.

Protects Downstream Systems

Serves as an effective pre-treatment for processes like RO, extending membrane life and enhancing performance.

Compact and Modular Design

UF systems are space-saving and easy to scale, making them ideal for various industrial and municipal applications.

Low Energy Consumption

Operates at low pressures, reducing energy costs compared to other filtration methods.

Enhanced Water Reuse

Produces high-quality water suitable for reuse in industrial processes or as feedwater for advanced treatment stages.

Applications of UF Technology

Pre-Treatment for Reverse Osmosis

UF ensures efficient removal of suspended solids and microorganisms, improving RO performance and durability.

Industrial Process Water

Supplies clean water for use in manufacturing, cooling, and boiler systems.

Wastewater Recycling

Removes impurities to enable reuse of treated wastewater in industries like textiles, food processing, and power generation.

Drinking Water Treatment

Produces safe, clear water for municipal and community use.

Effluent Treatment

A critical component in achieving compliance with discharge standards by removing fine particles and pathogens.
