    Abstract: A large vault or tank receives the runoff water to be cleaned. There are one or more small tanks in the large tank (vault). Each small tank is inverted and receives water at its open lower end, from the large tank. The water entering the small tank rises, as the water level in the large tank rises, and flows upward through a filter. When the water level rises above the top of the filter it enters an outlet tube or pipe and then flows downwardly along the center-line of the filter. A float, a valve and a check valve may cause the system to function as a siphon and feed the filtered clean water to an outlet. Alternatively the siphoning effect will occur if the inside diameter of said outlet tube is small enough to form a partial vacuum.

    Abstract: A filtering apparatus for removing impurities out of a lubrication oil for use in an internal combustion engine including low and high density filters having inlets commonly connected to an inlet conduit through which the lubrication oil to be filtered is supplied, an orifice arranged in an outlet conduit of the low density filter to produce a reduced pressure due to a fast oil flow and a conduit connected between an outlet of the high density filter and the orifice. Due to the reduced pressure applied to the outlet of the high density filter, a part of the oil is effectively sucked into the high density filter.

    Abstract: 1,181,051. Filter bed back-washing. CESKOSLOVENSKA AKADEMIE VED. 1 Jan., 1968 [7 Jan., 1967; 5 Dec., 1967], No. 13/68. Heading BID. A filter bed F is backwashed automatically when the level of unfiltered water rises sufficiently for level monitor 13 to close filtrate outlet valve 12, whereupon siphon S 2 starts and produces suction which acts through tube 6 to start siphon S 1 , whereafter unfiltered water flows from tank 10, upwards through bed F and to waste through siphon S 2 , expanding the bed. Monitor 13 also starts a timer 9, which subsequently admits air to both siphons by opening valve 7 and stops the backwashing, opens valve 4 to discharge the first filtrate following backwashing to waste and finally closes valve 4 and opens valve 12. Tank 10 acts as a preliminary purifying stage by virtue of a sludge blanket B therein, through which water flows upwards.

    Abstract: A syphon filtration system is a low head, small foot print, long operating cycle, gravity filtration system for treatment of water and wastewater, with one-stage or two-stage filtration in one vessel with different filtration media of sand, anthracite, granular activated carbon or other proprietary filtration media. The one-stage filtration system removes suspended solids or dissolved impurities and the two-stage filtration system removes suspended solids and dissolved impurities. In the two-stage filtration system, each filtration stage can be backwashed independently or both stages can be backwashed simultaneously. Novel syphon piping and controls design extend the filtration operating cycle and reduce the filter apparatus headroom, and the filter backwash water volume requirements.
