Ultrafiltration has larger pores and high permeability with less osmotic effects that allows ultrafiltration to operate at relatively lower pressure than nanofiltration and reverse osmosis and is therefore it is least costly to operate. Ultrafiltration is widely used in industry as pretreatment for other forms of purification such as ion exchange and reverse osmosis, gelatin and protein concentration in the pharmaceutical industry, sugar clarification in the food and beverage industry, cheese and whey concentration, production of ultra pure water, clarification of juice, downstream processing, membrane bioreactors, treatment of bleach plant effluents, and recovery of lignin compounds in the pulp and paper industry. Ultrafiltration can be used to reject virus, bacteria, pyrogens, endotoxins, and particulates but not ionic species. Hollow fiber configuration is widely used in the ultrafiltration processes. The benefit of this construction is that it allows for backwashing of the membrane when the filtrate or product flow rate has decreased due to accumulation of material on the membrane. The ultrafiltration membrane is capable of removing colloidal materials, fine suspensions, bacteria, virus, suspended material and large dissolved molecular weight organic materials.Advantages of Ultrafiltration Equipment over Conventional Media FiltrationImproved product qualityProduct SDI typically less than 1Removal of virus, and bacteriaRemoval of microbiological matterRemoval of colloidal matterColloidal Silica ReductionImprovement of downstream Reverse Osmosis (RO) performanceConsistently treated water quality irrespective of changes in feed water qualityUltrafiltration Equipment ApplicationsPackaged drinking water Surface water filtrationRO feed water Waste water recycleLatex paint wastewater treatment Oil removal / Oil refining processPetrochemical waste water treatment Dialysis machineMunicipal water Effluent recycleUltrafiltration Equipment Process Ultrafiltration is another type of membrane filtration, which is pressure driven water filtration process. In ultrafiltration process membrane pore size plays important role; feed water is pressed into modules through pump, depending upon the pore size of membranes contaminants are rejected and filtered water is taken out in storage tank or further sent as ro feed water. In water treatment, ultrafiltration is utilized in two different operational modes such as Dead-End and Cross-Flow. In Dead-End ultrafiltration process, without circulation overall quantity of feed water is pressed through the membrane module; whereas, in Cross-Flow process the feed water passes parallel to the membrane face, one part is passed through membrane and other part is re-circulated to create turbulences over the membrane. Ultrafiltration is considered more effective as compared to traditional water filtration. An Ultrafiltration Filter System is used in turbidity removal; in addition, it also removes bacteria, virus, microorganisms, particulate material, and natural organic materials from the water.
