Abstract
A swimming pool bi-flow filter has been described herein. The invention includes the following integral structural components: an influent conduit, an effluent conduit, an influent trough and a plurality of influent and effluent laterals. Ports in the influent conduit and the influent trough receive water from a source, such as swimming pool. The water entering the influent conduit flows upwards through the influent laterals to the effluent laterals, while the water entering the influent trough overflows into the filter and flows downwards to the effluent laterals. The water then passes through the effluent laterals and into the effluent conduit. As previously mentioned, the conduits, trough and laterals are an integral part of the structure, which necessarily means that thinner materials may be used in constructing the filter, without the loss of strength or durability.
