Abstract
1,118,923. Filter for water. UNIT SWIMMING POOLS Ltd. 11 Jan., 1965 [11 Oct., 1963], No. 40179/63. Heading B1D. A plurality of inward-flow filter elements are mounted in spigots 14 on a common filtrate conduit 10, which is connected by sleeves 30 to outlet sockets 26, 28 through the housing wall at both ends. Elements (2) are clamped in place (Fig. 1, not shown) and comprise two spaced expanded metal sheets over which a flat synthetic textile sack is stretched (Figs. 4, 5, not shown). The filter is used for swimming pool water and is connected to a circuit (Fig. 3, not shown) whereby diatomaceous earth, added to strainer (56), is first applied to the filter elements as water is delivered to inlet (60) from the pool. Strainer (56) has a further inlet (62) leading to a skimmer for the pool. Pool water may also be delivered in reverse flow to remove the filter aid from the elements to waste (42). Alternatively water may be pumped round a closed circuit to hold filter aid on the elements without any connection to the pool.
