Ultrafiltration ( UF )

Ultrafiltration (UF) is dead-end or crossflow filtration process, that removes colloids, emulsions, emulsified oils, suspended solids, and other large molecular weight materials from water and other solutions. UF membranes are identified by their molecular weight cut-off. UF system is beneficial at solutions containing suspended solids, bacteria, and high concentrations of macromolecules, including enzymes, oil and water, fruit juice, milk and whey, electrocoat paints, pharmaceuticals, poly-vinyl alcohol and Gelatine, potable water, and tertiary wastewater etc.

WPC/WPI
Ultrafiltration membranes are an essential process technology in the concentration and purification of whey protein concentrates and isolates from cheese whey.

MPC/MPI
The use of ultrafiltration membranes is growing significantly in the concentration and purification of milk proteins across the world.

Brine Clarification
The clarification of brine solutions via ultra filtration is an important step in the curing of cheese by preventing the growth of molds on the surface and providing an optimal amount of lactic acid for proper curd ripening.

Enzyme/Protein Concentration
The use of ultrafiltration membranes for enzyme concentration has been accepted as a standard separation process around the world, allowing for the concentration of enzymes and proteins while allowing salts and water to pass through the membrane.

Endotoxins and Pyrogen Removal
Ultrafiltration has the ability to effectively remove pyrogens and endotoxins from solutions, which is critical to the quality control in the production of biopharmaceutical products.

Blood Plasma Processing
Ultrafiltration membranes are able to simultaneously concentrate and purify blood plasma for use as a food additive.

Gelatin
Concentration and Purification – Ultrafiltration membranes provide optimal flux and retention rates important for the concentration of gelatin and removal of microorganisms and bacteria.

Plant Extract Processing
Plant extracts can be concentrated and purified through the use of ultrafiltration technology, resulting in higher yields compared to conventional processing methods.

Corn Wet Milling
Membrane filtration technology is used throughout the corn wet milling process and ultrafiltration in particular can be used to separate nutrients and starch, adding value in the process.

Fruit Juice Concentration
Ultrafiltration membranes are able to removal much of the starch, pectin, microbes, and proteins found in juice processing in order to produce high-quality juices.

Oil Removal in Wastewater Treatment
The removal of oils present in many industrial wastewater, streams has become increasingly necessary, in order to accommodate stringent discharge regulations, and growing manufacturing costs. The, utilization of ultrafiltration is an effective method.

Cathodic Ecoat Paint Recovery
Ultrafiltration is a key separation process necessary for concentration and recovery of cathodic ecoat paint, and production of permeate used in rinse stages. In the electro-coating process for applying water-soluble paints on automobiles and other metal products, our filtration systems recover more than 99% of paint resin and pigments, dramatically improving process efficiency and reducing waste. Working closely with manufacturers to understand their processes, we have pioneered solutions for improved cost-efficiency and performance. Our ultrafiltration and nanofiltration membranes for anodic and cathodic electro-coat paint can decrease deionized water consumption, reduce wastewater, improve paint solids recovery, control paint bath conductivity and potentially limit defects.

Process Wastewater Treatment
With the ability to reject particulates, bacteria, proteins, and polysaccharides, ultrafiltration can be used in combination with other technologies in the reduction of contaminant loads in industrial wastewater effluent.
