Description
REVERSE OSMOSIS of RO is one of types of membrane filtering where the membranes with the smallest size of time separating molecules and ions less than 0,0005 in size µм and passing only water are used. The mechanism of division has diffusion character. Because of high osmotic pressure operating pressure for reverse osmosis fluctuates in limit from 1 to 10 MPa.
In practice, process of reverse osmosis is applied to performance of two main objectives:
• recuperations of pure solvent (most often waters) in almost pure state without the content of the colloidal and other inclusions remaining in concentrate;
• selective division of substances between filtrate and concentrate.
Main application of Reverse osmosis
• introductory condensation of serum, permeate after ultrafiltration, milk, fruit juice (for example, apple);
purification of permeate after reverse osmosis (process of RO-Polisher) and nanofiltering, condensate after condensation of milk, fruit juices on vacuum-evaporator devices.
When using installation of reverse osmosis for milk condensation, concentration most often is carried to 29 solids. The permeate received at the same time represents technology water. Similar result receive when using reverse osmosis for concentration of skim milk with final indicators of condensation 28-29%. It means that the condensation of whole and skim milk is extremely effective when carry out condensation by 3 times!, as it reduces production expenses when using vacuum-evaporator installations on those volumes of remote moisture which, in case of use of installations of membrane filtering, can be returned in production.
Use of method of reverse osmosis is especially effective if the enterprise specializes in production of concentrates or dry dairy products. Also those enterprises which transport serum or milk for drying on the next enterprises receive essential economy on transportation costs as volumes of transportation are reduced many times.
