UF Plants Manufacturer & Supplier for Advanced Water Purification

Ultrafiltration (UF) is a pressure-driven process that removes suspended solids, bacteria, and high-molecular-weight solutes, but allows dissolved salts (TDS) to pass through. RO, on the other hand, removes dissolved ions. UF is often used to protect RO membranes from fouling.

Our industrial UF membranes typically feature a pore size ranging from 0.01 to 0.1 microns. This acts as a definitive physical barrier against 99.99% of bacteria, viruses, and colloidal silica, providing water with extremely low turbidity.

By providing water with a Silt Density Index (SDI) consistently below 3, UF prevents the organic and colloidal fouling of RO membranes. This leads to fewer RO cleanings, lower operating pressure, and a significantly longer RO membrane lifespan.

In Dead-End filtration, all the feed water passes through the membrane, which is energy-efficient but requires frequent backwashing. Cross-Flow filtration keeps the water moving parallel to the membrane, reducing the build-up of a filter cake, ideal for high-turbidity effluents.

UF is excellent at removing physical color caused by suspended organics (colloids). However, for dissolved chemical color or odors, a combination of UF with Activated Carbon or specialized chemical oxidation is required.

We perform 'Pressure Decay Tests' or 'Bubble Point Tests.' By applying air pressure to the membrane, we can detect even a single broken fiber. This ensures that the microbial barrier remains 100% effective at all times.

Because UF handles a much higher load of physical solids, it requires a short backwash (reversing the flow) every 30–60 minutes to dislodge particles from the fiber surface. This process is fully automated in Tara Enterprises systems.

A CEB is a backwash where a small amount of chemical (like Sodium Hypochlorite or Acid) is added to the backwash water. It provides a deeper clean than water alone, removing bio-growth and mineral scaling without a full CIP shutdown.

With a robust pre-filtration system and disciplined backwash/CEB protocols, high-quality UF membranes can last 3 to 5 years. Membrane life is largely determined by the frequency of chemical cleanings and the feed water characteristics.

Yes, UF is the industry standard for tertiary treatment. It produces clear, silt-free water from ETP/STP outlets, making it perfect for reuse in cooling towers, irrigation, or as a feed for high-end recycling RO plants.
