Abstract

A liquid filtering device includes an inlet pipe (11), an outlet pipe (5) and a chamber (3) connected therebetween. The chamber (3) includes a liquid-filtering filter (4) and connects with liquid analyzing equipment, for instance sewage water analyzing equipment. The chamber (3) also connects with a filtered-liquid container (6), through the medium of a throughflow pump (9). The throughflow pump (9) functions to allow liquid to pass from the chamber (3) to the container (6) and, after a predetermined time period has lapsed, to pump the filtered liquid back from the container (6) and through the filter (4) for a given time duration, such as to clean the filter.
