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.
Claims19
A syphon filtration system comprising:
- a filter unit,
- filter external piping and control valves,
- a filter controller;
- said filter unit comprises a filter vessel, filter media, an outlet water internal pipe, a water level sensor and controller, an inlet water internal distribution pipe, and a backwash water collector trough;
- said filter external piping and control valves comprise an inlet water pipe and inlet water valve, an outlet water pipe, an outlet water syphon pipe, an outlet water discharge pipe, a syphon vent pipe, a rinse water discharge pipe, a backwash water supply pipe, a backwash water discharge pipe, an air vacuum pump and an outlet water control valve, a syphon control valve, a rinse water discharge control valve, a backwash water supply control valve, a backwash water rate of flow control valve;
- and
- said filter controller is electrically connected to said control valves, said water level sensor and controller, and an external control station, wherein said filter controller receives input signals from said water level sensor and controller and said external control station to activate open/close said control valves to control said filtration system operation in different cycles of filtration both without syphon action wherein said outlet water control valve and syphon control valve are open, and said rinse water discharge control valve and backwash water supply control valve are closed, and with syphon action wherein said outlet water control valve is open, and said syphon control valve, rinse water discharge control valve and backwash water supply control valve are closed.
A syphon filtration system comprising:
- a filter unit,
- filter external piping and control valves,
- a filter controller;
- said filter unit comprises a filter vessel for two-stage filtration media, two-stage filtration media, an internal piping, a water level sensor and controller, and a differential pressure switch;
- said filter external piping comprises inlet water pipe and an inlet water valve, independent water outlet pipes and backwash water collector troughs, and backwash water supply pipes for each filter media, a common water outlet syphon pipe, a common water outlet discharge pipe, a common syphon vent pipe, a common air vacuum pump, a common rinse water discharge pipe, a common backwash water discharge pipe for both filter media, control valves and rate of flow control valves for each said backwash water supply pipes, a control valve for said common water outlet pipe, a control valve for said common syphon vent pipe, a control valve for said common rinse water discharge pipe;
- said filter controller is electrically connected with said water level sensor and controller, said differential/pressure switch, said control valves and an external command station to activate the filter system operating cycles for production without syphon action wherein said control valves for said common water outlet pipe and said syphon vent pipe are open, and said control valves for said rinse water discharge pipe and said backwash water supply pipes are closed, and production with syphon action wherein said control valve for said common water outlet pipe is open, and said control valves for said syphon vent pipe, said rinse water discharge pipe and said backwash water supply pipes are closed.
