The article states that in recent years, increasing demand for fine separation of aggressive and high-temperature liquid media (especially aggressive waste water) has dictated the need to develop a new generation of filtration equipment. Processes of cross-flow micro- and ultra-filtration, that is, processes of membrane separation of solutions and suspensions under pressure with simultaneous movement of the liquid being separated along the surface of the membrane filtering element, have come into increasingly broader use for solution of these problems.

The article states that the separation of suspensions is a production process that has come into widespread use in many branches of industry. The equipment used for this process should therefore be effective and highly productive, reliable, and long-lived. Self-regenerating filters consisting of cylindrical housing 4 with cylindrical filtering element 3 mounted coaxially within the housing are classed with this type of equipment. It was established from the processing of the experimental data obtained that the tangential velocity component of the liquid flow in the filter remains virtually unchanged over the height and radius of the separation zone.
