Abstract
A filter apparatus in which a generally horizontal bed of filter material is supported on a porous support and is divided by spaced partitions into individual filter cells above the support and individual filter compartments below the support, and a carriage is mounted for movement along the filter bed and has an waste water pump and collector hood that moves along the top of the bed to collect backwash effluent therefrom and direct it to a waste water trough, and a backwash pump and backwash head arranged to direct backwash fluid into the compartments below the porous support. A flow measuring weir is associated with the waste water trough and the backwash pump is arranged so that its output can be selectively delivered to the waste water trough whereby the flow measuring weir can be used to measure both backwash and waste water flow rates.
