The ultrafiltration plant in Delhi can be used to reject the bacteria, virus, endotoxins, pyrogens, and particulates but nit ionic species. The hollow fiber configuration is extensively used in the Ultrafiltration processes. The benefit of this construction is that it allows for the backwashing of the membrane when the filtrate or product flow rate has decreased because to accumulate material on the membrane. The ultrafiltration membrane is capable of removing colloidal materials, bacteria, and fine suspensions material, and large dissolved molecular weight organic materials
