A low-pressure membrane method is employed in the Industrial Ultrafiltration Plant to remove bacteria, viruses, and high molecular weight compounds colloidal and particulate materials from a feed stream. Ultrafiltration features bigger pores and high permeability with less osmotic effects, allowing it to run at lower pressures than nano filtration and reverse osmosis and hence be the least expensive to run. The ultrafiltration membrane is capable of eliminating colloidal materials, tiny suspensions, bacteria, viruses, suspended material, and organic compounds with a high dissolved molecular weight.
