Abstract
A description is given of a method as well as a filter device for filtration of a liquid containing suspended solid particles, said method comprising a filtration stage wherein the liquid is fed under pressure into a porous, tubular filter (1) causing the liquid to permeate outwardly as a filtrate through the filter and the solid particles to be deposited as a ring-shaped filter cake (7) on the inner side of the filter, and a cleaning stage wherein the filtration process is temporarily stopped and the filter cake (7) is removed from the inner side of the filter. The method and the filtration device are characterized in that a cleaning fluid during the cleaning stage via a number of nozzles (9) provided inside the filter (1) is injected in direction towards the inner side of the filter. Hereby is obtained a quick and efficient cleaning of the filter, hence avoiding blockage of the filter, the possibility of shorter filtration cycles resulting in higher levels of filtration efficiency, a low pressure drop across the filter and hence accelerated flow of filtrate and prolonged lifetime of the filter, leading to lower maintenance costs. This is primarily due to the fact that substances including solidified scales which cause blockage of the filter will be effectively removed by directing jets of a cleaning fluid directly against the inner side of the filter, and hence directly against these substances.
