A filter comprises a housing 1 containing filter media 9, a contaminated flow inlet 2 and a discharge outlet 8. The inlet is a substantially vertically aligned, elongate manifold 5 with a plurality of flow distribution outlets disposed along its length. Preferably the manifold has a flow outlet 6 which directs flow laterally, away from the discharge outlet 8 in a direction towards a sidewall of the housing. The discharge outlet 8 may be accessed through a chamber within the housing which contains a second filter media 11 which is of larger particle size than the first filter media 9. A filter media fluidising unit may be provided at the base of the housing. Optionally, the filter includes an ultrasonic unit 19, a heating unit 20 and means for applying magnetic force or AC/DC current. Advantageously, filtration and distribution of contaminated flow is improved. |
