TREATMENT OF PARTICLE-BEARING LIQUID

摘要

A system for treatment of particle bearing liquid comprises control means (100) and an homogeniser valve (46), said control means being operable to cause a gap defined by the homogeniser valve to be periodically temporarily increased thereby to allow any accumulated particulate matter to pass through the valve, the valve then continuing to provide an homogenisation of subsequently flowing liquid when the valve returns to its normal mode of operation.
