Claims13
A separation apparatus for separating contaminants from water comprising:
- a container (2) for receiving contaminated water, the container including a contaminated water inlet (3) and a first contaminant outlet;
- a filter (5) for separating contaminants from the contaminated water, the filter being located at a lower portion of the container (2);
- a water outlet (9) through which water which has passed through the filter (5) may flow;
- a screw or a linear compression device arranged within a lower portion of container (2) adjacent at least a portion of the filter (5) for compressing any contaminants accumulated on, or adjacent to the filter (5) and urging the accumulated contaminants towards and through the first contaminant outlet;
- at least one gas inlet (7) arranged to supply gas, through the filter (5) and into the container (2);
- and
- an actuator operably connected to the screw or linear compression device to cause movement thereof.
