A centrifugal microstrainer includes a closed cylindrical vessel with a cylindrical screen within, both rotating about a hollow shaft forming a common central axis. Liquid-solid admixture introduced through the shaft is flowed radially outward subjected to centrifugal acceleration, and forced back through the screen under pressure with particles too large to pass the screen remaining on its outboard side. The centrifugal force applied by the rotation of the vessel acts on these larger particles pushing them away from the screen thus preventing clogging and permitting substantially continuous operation. The device may be operated as a classifier by providing a plurality of concentric screens of decreasing mesh size spaced outwardly from one another in conjunction with properly sized chokes - Source: Microstrainer Apparatus And Method

Microstrainers consists of a rotating drum with a stainless steel micromesh fabric. The mesh size can range from 15 μm to 64 μm so that very fine suspended matter such as algae and plankton can be trapped. The trapped solids are dislodged from the fabric by high-pressure water jets using clean water, and carried away for disposal. Source

Microstrainers consist of a finely woven stainless steel wire cloth mounted on a revolving drum,

that is partially submerged in the water. Water enters through an open end of the drum and flows out through the screen, leaving suspended solids behind. Captured solids are washed into a hopper when they are carried up out of the water by the rotating drum. Source
