Abstract
A radial or crossflow media filter comprising a housing such as a vessel or tank (1), the housing containing filter media (9), a contaminated flow inlet (2) and a discharge outlet (8), the inlet comprising a manifold (5) situated within the housing, the manifold (5) having flow outlets (6) which are directed laterally, away from the discharge outlet (8). The flow inlet may comprise a substantially vertically aligned elongate tubular manifold (5) with a plurality of flow distribution holes or slots disposed along its length. Furthermore, the discharge outlet (8) may be accessed through a chamber within the housing which contains a second filter media (11) which is of larger average particle size than the first filter media (9).
Claims18
A radial or crossflow media filter comprising a housing containing filter media, a contaminated flow inlet and a discharge outlet, the contaminated flow inlet comprising a manifold situated within the housing, the manifold having a flow outlet which directs flow laterally, away from the discharge outlet, and a discharge chamber situated within the housing upstream of the discharge outlet, the discharge chamber containing a second filter media which is of a larger average particle size than the rest of the filter media in the housing.
A radial or crossflow media filter comprising a housing containing filter media, a contaminated flow inlet and a discharge outlet, the contaminated flow inlet comprising a manifold situated within the housing, the manifold having a flow outlet which directs flow laterally, away from the discharge outlet, and a discharge chamber situated within the housing upstream of the discharge outlet, the discharge chamber being formed from a filter screen and surrounding the discharge outlet, where the discharge chamber contains a second filter media which is of a larger average particle size than the rest of the filter media in the housing.
A method for treating contaminated flow comprising:
- providing a radial or crossflow media filter comprising a housing containing filter media, a contaminated flow inlet and a discharge outlet, the contaminated flow inlet comprising a manifold situated within the housing, the manifold having a flow outlet which directs flow laterally, away from the discharge outlet, and a discharge chamber situated within the housing upstream of the discharge outlet, the discharge chamber containing a second filter media which is of a larger average particle size than the rest of the filter media in the housing;
- introducing contaminated flow into the contaminated flow inlet;
- contacting the flow with the filter media and the second filter media;
- and
- discharging cleaner flow through the discharge outlet.
