A filter apparatus for filtering a liquid which includes trash, the device comprising: a drum for receiving said liquid and trash wherein said drum includes at least one drum aperture; a plurality of filter devices for filtering said liquid, each said filter device having a cavity formed by a pair of filter panels which are spaced apart, said panels being adapted for filtering said liquid; a plurality of filter supports (245; 317) each comprising an attachment portion and a transversely orientated strut portion extending radially outward from the drum and arranged to support said filter devices; and wherein each filter support is coupled to said drum and includes a single aperture in fluid communication with a corresponding drum aperture and adjacent cavities of the filter devices characterized in that: - the attachment portion includes a first section which extends from an end of the strut portion and the attachment portion also includes a second section which extends from the end in a direction opposite to the first section to thus form an inverted T-shaped filter support; - the attachment portion further includes said single aperture which extends along the first and second sections of the attachment portion and along the strut portion to thus form a substantially inverted T-shaped aperture which corresponds to the shape of the filter support; and in that - said single aperture has a size substantially equal to or greater than a size of said drum aperture. a drum for receiving said liquid and trash wherein said drum includes at least one drum aperture; a plurality of filter devices for filtering said liquid, each said filter device having a cavity formed by a pair of filter panels which are spaced apart, said panels being adapted for filtering said liquid; a plurality of filter supports (245; 317) each comprising an attachment portion and a transversely orientated strut portion extending radially outward from the drum and arranged to support said filter devices; and wherein each filter support is coupled to said drum and includes a single aperture in fluid communication with a corresponding drum aperture and adjacent cavities of the filter devices characterized in that: - the attachment portion includes a first section which extends from an end of the strut portion and the attachment portion also includes a second section which extends from the end in a direction opposite to the first section to thus form an inverted T-shaped filter support; - the attachment portion further includes said single aperture which extends along the first and second sections of the attachment portion and along the strut portion to thus form a substantially inverted T-shaped aperture which corresponds to the shape of the filter support; and in that - said single aperture has a size substantially equal to or greater than a size of said drum aperture. - the attachment portion includes a first section which extends from an end of the strut portion and the attachment portion also includes a second section which extends from the end in a direction opposite to the first section to thus form an inverted T-shaped filter support; - the attachment portion further includes said single aperture which extends along the first and second sections of the attachment portion and along the strut portion to thus form a substantially inverted T-shaped aperture which corresponds to the shape of the filter support; and in that - said single aperture has a size substantially equal to or greater than a size of said drum aperture.
