Abstract
The present disclosure relates to a filter apparatus (1) for mechanically filtering a liquid (W). The filter apparatus (1) includes a filter chamber (5) for containing a plurality of filter elements (7) for filtering the liquid (W). A steriliser unit (36) is provided for sterilising the liquid (W) and/or the filter elements (7) in the filter chamber (5). The present disclosure also relates to a method of filtering a liquid (W) including sterilising the liquid (W) and/or the filter elements (7) in the filter chamber (5).
Claims25
A filter apparatus (1) for mechanically filtering a liquid (W), the filter apparatus (1) comprising:
- a filter chamber (5) for containing a plurality of filter elements (7) for filtering the liquid (W);
- and
- a steriliser unit (36) for sterilising the liquid (W) and/or the filter elements (7) in the filter chamber (5).
A filter apparatus (1) as claimed in any one of the preceding claims, wherein, in use, the filter elements (7) form a filter pack (29) in the filter chamber (5), the steriliser unit (36) being disposed proximal to a region where the filter pack (29) forms.
A filter apparatus (1) as claimed in any one of the preceding claims, wherein the filter chamber (5) comprises a liquid inlet (12) and a liquid outlet (14), the steriliser unit (36) being disposed proximal to the liquid outlet (14).
A filter apparatus (1) as claimed in any one of the preceding claims, wherein the steriliser unit (36) comprises at least one light source (37) for emitting UV light.
A filter apparatus (1) as claimed in any one of the preceding claims, wherein the filter elements (7) have an open cell structure.
A filter apparatus (1) as claimed in any one of the preceding claims, wherein the filter apparatus comprises means for introducing air into the filter chamber (5) through one or more air inlets (25) to agitate the filter elements (7).
A filter apparatus (1) as claimed in any one of the preceding claims comprising a control unit for controlling activation of the steriliser unit (36).
A method of filtering a liquid (W), the method comprising:
- establishing a flow of liquid (W) through a filter pack (29) formed of a plurality of filter elements (7), and
- sterilising the liquid (W) and/or the filter elements (7) in the filter chamber (5) while the liquid (W) flows through the filter pack (29).
