A siphon float system comprises a central dowel in communication with a batch reactor. A siphon float is slidably engaged with the central dowel, wherein the siphon float is hydraulically operated. A plurality of valves are in communication with the siphon float, wherein the plurality of valves selectively control a flow of water. one or more dowel pegs contact one or more valve triggers based on a level of fluid in the batch reactor; and a plurality of hoses to direct the flow of water.

A drainage apparatus (100, 300-800) for siphoning liquid between first and second reservoirs (102, 104) is disclosed. In a first embodiment, the apparatus (100) includes a conduit arrangement having a first opening (112) disposed in the first reservoir (102), a second opening (114) disposed in the second reservoir (104) and a liquid injection inlet (106M2) arranged between the first and second openings (112,114), and a plurality of valves (108, 110) for controlling flow of the liquid along the conduit arrangement. A method (200) for priming the drainage apparatus (100) comprises directing liquid into the conduit arrangement at (202) via the liquid injection inlet (106M2) to fill up most of the conduit arrangement as controlled by the valves' configuration; directing liquid into the first reservoir (102) to enable more liquid to enter into the conduit arrangement via the first opening (112) to flood the conduit arrangement to form a continuous liquid flow path which extends from the first opening (112) up to at least the second opening (114), the continuous liquid flow path creating a siphon; and with the first opening (112) kept below the liquid's surface level in the first reservoir (102), stopping the flow of liquid into the first reservoir (102) to achieve a state of equilibrium of the siphon to prime the conduit arrangement. After the priming and in use, the siphon is triggered when more liquid is added into the first reservoir (102) which causes the added liquid to be siphoned to the second reservoir (104) via the primed conduit arrangement.

A siphon assembly includes an ascent conduit having a conduit inlet, a descent conduit having a conduit outlet, and a flow passage through the ascent conduit and the descent conduit. The flow passage connects the conduit inlet and the conduit outlet via a siphon crest. The siphon assembly also includes a filter arranged to filter a siphonic flow towards the siphon crest.
