Apparatus for storing organic material

A filter for filtering particulate material from a contaminated fluid, comprising:

• a housing having an inlet for receiving the contaminated fluid from a contaminated fluid source and an outlet for releasing filtered fluid from the housing;
• a sieve mounted within the housing, the sieve having a generally cylindrical shape and being mounted on a spindle such that the sieve is able to rotate about a central axis, the sieve having perforations to permit the contaminated fluid to pass;
• a turbine assembly mounted to an end of the sieve, the turbine assembly being actuable to impart rotational motion to the sieve to rotate the sieve about the central axis;
• and
• a spray bar centrally mounted within the sieve to spray fluid in a radial direction toward an inner surface of the sieve;
• wherein, the outlet is located within the sieve such that the contaminated fluid passes from the inlet and through the sieve to exit from the outlet as filtered fluid and any particulate material present in the contaminated fluid is removed by the sieve, and wherein particulate material collected by the sieve is removed from the housing by activating the turbine assembly to rotate the sieve and the spray bar to spray fluid onto the inner surface of the sieve thereby releasing the particulate material from the sieve for disposal from the housing.
