<p>A screen assembly in which the screen (10) is in the form of an inverted semi-circular trough the foul flow (A) to be screened approaching the underside of the screen so that debris which is filtered falls away from the screen by gravity so minimising blockages and 'blinding' of the screen. A helical sweeper (20) is provided to minimise adherence to the screen.</p> |
