Mechzeal Filtration offers the widest range of ultrafiltration membranes available to provide maximum flexibility in solving unique process challenges. Available in both spiral wound and flat sheet membrane configurations, We can customize ultrafiltration membranes and membrane systems to meet the specific application goals of our customers.
Ultrafiltration is used for the separation of suspended solids, colloids, bacteria and virus. This technique uses membranes with pore size between 1-100nm.Ultrafiltration is very effective at removing very small particles as well colloidal particles which can quickly foul reverse osmosis membranes, and then resulting in reducing the silt density index of the water. For this reason, it frequently serves as pre-treatment for surface water, seawater, and biologically treated municipal water upstream of RO.
In ultrafiltration, thewater flow is directed through a membrane in a cross flow direction, and a portion of input water flows across the surface of the membrane at a precise rate of flow and pressure. This allows most contaminant stuffs to be removed, but also allows the membrane surface to stay clean, and eliminating the fouling that can leave other systems ineffective until manual cleaning occurs.UF is particularly meant and effective for discarding the colloid (emulsion). It is an effective pre-treatment to Reverse Osmosis used in desalination.It can also be used as a pre-treatment for water that will go through a reverse osmosis system. Water that has been through the ultra-filtration process can also be used as drinkable water in hotels, resorts, recreational centres and the like.

How UF work:
Empty/hollow fibres of membrane material is used in ultrafiltration and the feed water flows either inside the shell, or in the lumen of the fibres. What is retained is the suspended solids and particles of high molecular weight, on the other hand, water and low molecular weight solutes pass through the membrane. Ultrafiltration is somewhat similar to reverse osmosis, microfiltration or nanofiltration, except in terms of the molecule size it retains. When comparing and strategically combining with other purification technologies in a complete water system, UF is ideal for the removal of colloids, proteins, bacteria, pyrogens, proteins, and macromolecules larger than the membrane pore size from water.
