Water filters which comprise a multitude of discrete filter media elements in a chamber require periodic cleaning. However, the elements tend to become adhered to one another and to the interior surface of the chamber. The invention provides a water filter for use with ponds, comprising a filter chamber for containing filter media, and a first movable cutting member provided substantially immediately adjacent the interior wall of the chamber for movement across the surface of the interior surface of the wall to break the adherence of filter media to the interior wall.
Dosing chambers, for use with pressurized water filters of the type used with ponds, require isolation before accessing to prevent water egress. The invention comprises a chamber in which dosing substances may be placed, a water inlet and a water outlet, a lid for sealingly closing the chamber, a valve for closing the water inlet and an interlock means for operating the valve to close the water inlet as the lid is removed, so that when dosing substances are placed into the chamber pressurized water is prevented from issuing through the inlet.
Abstract : Composite mechanical water filter media Water filters require filter media which may be a substantially single structure such as open-cell foam, or comprised of a plurality of relatively small elements. The present invention provides composite mechanical water filter media for use in mechanical water filters comprising a plurality of first elements having a first shape and a plurality of second elements having a second shape, the first and second shapes being substantially different from one another, the elements being arranged to interlock with one another.

Dosing chambers, for use with pressurised water filters of the type used with ponds, require isolation before accessing to prevent water egress. The invention comprises a chamber in which dosing substances may be placed, a water inlet and a water outlet, a lid for sealingly closing the chamber, a valve for closing the water inlet and an interlock means for operating the valve to close the water inlet as the lid is removed, so that when dosing substances are placed into the chamber pressurised water is prevented from issuing through the inlet.

Traditional fishponds are typically formed in a hole in the ground. Material is sometimes used as a liner either to provide waterproofing and/or ground stabilisation. Pre-formed solid walled liners are also known which are at least partially buried in use in the ground. The invention provides a free-standing fish fishpond structure (10) comprising a flexible waterproof liner (20) and support means (30) for supporting at least a portion of the liner to form a wall, wherein the liner includes at least one integral substantially transparent portion. This enables the possibility of fishponds in situations where there is no access to suitable ground for the at least partial burial of a liner, or the creation of a hole. Moreover, it provides a relatively easily erectable, dismantleable and portable fishpond.
