UV disinfection plants are designed to remove biological contaminants from natural, industrial and wastewater and bring water to the required standards of microbiology.
Ultrafiltration is a process of membrane separation as well as fractionation and concentration of substances performed by filtering a fluid under the impact of pressure difference before and after the membrane. The pore size of ultrafiltration membranes varies from 0.01-0.1 microns.
A typical application of ultrafiltration is the separation of macromolecular components from a solution with the lower limit of the solute being separated corresponding to molecular weights of several thousand. A process, called nanofiltration, being intermediate between ultrafiltration and reverse osmosis, is used for the separation of solute with molecular weights from several
Ultrafiltration membranes belong to porous membranes, and in them the particle retention is mainly determined by their size and shape relative to the pore size of the membrane, and the transport solvent is directly proportional to the applied pressure. So, the separation mechanism on ultrafiltration membranes is the sieve one.
