  • the present invention relates to a device for throughfeed of greywater to a water user, more particularly for immediate use thereof by the water user, in addition to a greywater system provided therewith and method for applying same.
  • One method of making efficient use of energy and environment is to reuse lightly contaminated water.
  • mains water which is treated with considerable effort and at a great cost in wastewater purification plants
  • less clean non-potable water can be used for some applications, such as for instance flushing the toilet.
  • Such lightly contaminated water is also referred to as greywater.
  • the saving of water resulting from the reuse of water furthermore results in a proportional reduction in the stress on the sewage system.
  • An object of the present invention is to at least partially obviate at least one or more drawbacks of the prior art.
  • the stated objective is achieved with the device for throughfeed of greywater to a water user according to the present invention, comprising:
  • a housing for receiving therein greywater supplied via a greywater feed; - a first flush pipe extending downward from the housing and connected directly to a sewer outlet; and
  • Such a device has the advantage that a cistern of the water user becomes unnecessary.
  • these parts together form a modular unit which can be arranged on a water storage unit.
  • the greywater system comprises, in addition to this modular unit, only several basic elements such as a frame, a water storage unit, a front wall and a control system.
  • the modular unit hereby reduces a greywater system to a system which can be assembled relatively easily from basic elements.
  • At least one of the flush pipes is controlled by a solenoid, wherein the core of the solenoid is connected to a spring.
  • the solenoid is further provided with a permanent magnet, preferably a shock-resistant supermagnet manufactured from NdFeB.
  • a permanent magnet has the advantage that it can be controlled by means of pulses and that no energy is used during rest - both in an attracted and repelled rest state.
  • a supermagnet in N45 (1.37 Tesla) has been found suitable.
  • the permanent magnet is arranged in the core of the solenoid.
  • arranging the permanent magnet in the core has the advantage that the play of forces is more advantageous than when the magnet is arranged in the coil. Placing a magnet in the core runs counter to the prejudice that magnets lose their magnetism under shock load.

  • the system comprises a control system (ECU) for thereby controlling inter alia actuators present in the system.

  • the outflow characteristic of which is known and is moreover substantially constant - since it will generally be (almost) completely full when flushed - the use of a relatively large storage tank from which water is discharged directly to a water user - so not via a cistern - has the drawback that the outflow characteristic can vary greatly according to the quantity of water stored in the storage tank, which
  • variation can lie typically in the range of 10 - 100 litres. About 6 litres is used as a minimum volume, while a storage tank can for instance store up to as much as 100 litres of greywater.
  • the volume flow, or the flow rate, of the water flowing from the storage tank to a water user depends on the water level in the storage tank, the outflow opening and the time .

  • a float such as the float present in the greywater device according to the invention which activates the emergency replenishment.
  • the volume can however also be determined in other manner, after which it is known which outflow characteristic will occur during the outflow to the water user.
  • the outflow opening or the time is then adapted such that a desired quantity of water is flushed from the storage tank to the water user.
  • the collecting reservoir of the greywater system comprises a volume of at least 10 litres so that sufficient greywater for at least two successive flushes can be stored therein.
  • the collecting reservoir is hereby distinguished from a conventional cistern of a toilet, which can only store sufficient water for a single flush.
  • a flush amount for flushing the toilet generally lies in the range of 4-6 litres of water.
  • the collecting reservoir which comprises at least 10 litres of volume, is therefore able to store sufficient greywater for at least two successive flushes.
  • the toilet can thus be flushed at least twice with a usual flushing volume of about 5 litres without interim feed of ⁇ grey) ater to the collecting reservoir.
  • the influencing means comprise a throttle or pinch valve controlled by a control system of the greywater system.

  • the greywater system further comprises:
  • a pump for thereby pumping water out of the storage tank to the water user.
  • the advantage hereof is that a cistern is also unnecessary for further water users, such as a toilet which is located at some distance and which can even be situated on a higher floor.
  • a water conduit with monitoring of unauthorized addition of branches is preferably applied.
  • Such a water conduit is the subject of Netherlands patent NL 1031270 of applicant.
  • the basic volume of water present in the storage tank is increased for each additional water user connected to the system.
  • the storage tank is always kept filled with a determined quantity of water for at least one flush of a toilet, for instance 6 litres. If there is no supply of greywater, the storage tank is replenished with mains water via the emergency replenishment until the desired basic volume of 6 litres of water is reached.
