Abstract
A water purification system for treating grey water from household appliances such as baths, showers, vanity basins and washing machine (11-15) has branch-off pipes (29-33) from the usual drain pipes (17-21) these branch-off pipes lead to a storage tank tank (35). The branched off water is filtered by a screen filter (51) then circulated by a pump (53) in series to a heater (55). The system also includes a sediment filter (57), a carbon filter (59), color filter (61), an ultraviolet radiation unit (63), and hence via a shut-off valve (71), to a storage tank (73). The purified grey water can be used for car-washing, and garden and lawn irrigation. The system can be retrofited to an existing home or installed in a new home.
Claims19
A water purification system adapted for use in a home or other facility which contains at least one application which discharges grey water into a sewer system, comprising:
- means for diverting said at least one grey water discharged from said appliance,
- a grey water purifier for receiving the grey water diverted from said at least one appliance, said purifier comprising:
- at least one filter for filtering said water,
- means for heating said water, and
- ultraviolet water sterilizer means for receiving said grey water and sterilizing said grey water to provide purified grey water,
- said means for heating said water being arranged to heat said water after it is discharged from said at least one appliance and before it is supplied to said sterilizer means so as to supply heated water to said sterilizer means, and
- means for discharging said purified grey water for non-potable uses.
A water purification system adapted for use in a home or other facility which contains at least one appliance which discharges grey water into a sewer system, comprising:
- means for diverting said at least one grey water discharged from said appliance
- a grey water purifier for receiving the grey water diverted from said at least one appliance, said purifier comprising:
- at least one filter for filtering said water,
- means for heating said water, and
- an ultraviolet water sterilizer means for receiving said grey water and sterilizing said grey water to provide purified grey water,
- said means for heating said water being arranged to heat said water after it is discharged from said at least one appliance and before it is supplied to said sterilizer means, so as to supply heated water to said sterilizer means, and
- means for discharging said purified grey water for non-potable uses, and means for connecting said at least one appliance to a sewer pipe by a drain pipe, said means for diverting said grey water comprising a branch-off pipe connecting said drain pipe to said grey water purifier and a cut-off valve in said drain pipe downstream of said branch-off pipe.
A water purification system adapted for use in a home or other facility which contains at least one appliance which discharges grey water into a sewer system, comprising:
- means for diverting said grey water discharged from said at least one appliance,
- a grey water purifier for receiving the grey water diverted from said at least one appliance, said purifier comprising at least one filter for filtering said water, and an ultraviolet water sterilizer means for receiving said grey water and sterilizing said grey water to provide purified grey water,
- means for discharging said purified grey water for non-potable uses, and
- means for connecting said at least one appliance to a sewer pipe by a drain pipe,
- said means for diverting said grey water comprising a branch-off pipe connecting said drain pipe to said grey water purifier a cut-off valve in said drain pipe downstream of said branch-off pipe, and a bypass pipe connecting said branch-off pipe back to said drain pipe downstream of said cut-off valve, said bypass pipe including a check valve arranged to pass water from said branch-off pipe to said drain pipe, but not in the reverse direction, said bypass pipe having an upwardly sloping portion so that water will not normally flow from said branch-off pipe back to said drain pipe unless it cannot flow to said grey water purifier.
