  • wash-water water contaminated with waste from the equipment
  • wash-water used to clean paint equipment and other trades equipment into the sewer. Accordingly professional painters, building sites and the like who generate large amounts of wash-water, employ third party contractors to remove and dispose of wash-water in an environmentally friendly manner. As it is quite expensive to handle such contaminated wash-water, a number of prior art devices and systems are known to separate waste from wash-water, thereby allowing contractors to only cart the waste away from site, and possibly allow for the recycling of the treated water.
  • a disadvantage of this prior art systems is that a substantial amount of time must pass before the water in the collection tank can be re-used, due to the time it takes for the waste to settle out of the wash-water.
  • the additive may be a "flocculant", as mentioned above, or a "coagulant". Coagulants clump, or coalesce, fine waste particles together into larger particles that are still relatively small (these particles are known as "pin floe”). Flocculants clump the fine waste particles into larger solids than produced by coagulants, and these larger solids settle out.

  • Figs. 1 to 4 show a preferred embodiment of a washing apparatus 1 in accordance with the present invention.
  • Washing apparatus 1 a method of washing trades equipment in accordance with the present invention.
  • Washing apparatus 1 is particularly suited to washing or cleaning painting equipment, such as paint brushes and rollers, but it may also be used for washing other trades equipment.
  • Washing apparatus 1 comprises an enclosure 2 mounted on a base 3.
  • Base 3 has openings 5 in its sides to enable a forklift truck to lift and move washing apparatus 1.
  • Enclosure 2 supports two washing receptacles, namely two removable wash trays 4. Wash trays 4 are at a height convenient for a person to wash equipment whilst standing. Equipment to be washed is supported by, or held above, wash trays 4 during washing.
  • the two wash trays 4 of this embodiment enable two people to wash equipment at the same time.
  • Supply tank 7 holds clean wash fluid 8.
  • “Clean wash fluid” means that the wash fluid is in a “clean state”.
  • Clean wash fluid 8 is typically substantially clean water or water recycled through washing apparatus 1 in a manner that will be described.
  • substantially clean water means mains tap water or chemically treated (recycled) water.
  • supply tank 7 is filled with clean wash fluid 8, which is usually substantially clean water, from an external source.
  • a first pump namely supply pump 9, delivers clean wash fluid 8 on demand through a supply line 10 to two trigger operated delivery nozzles 1 1.
  • Each trigger nozzle 1 1 is connected to supply line 10 by a flexible hose 12.
  • Each nozzle 1 1 directs a stream of clean washing fluid 8 at the equipment being washed.
  • Nozzles 1 1 are tapered, low flow nozzles with blade tips that produce a fan like stream of wash fluid 8 that is efficient for washing.
  • the flow rate through a nozzle 1 1 may be about 4 litres per minute.
  • Supply pump 9 starts automatically when the trigger of one of nozzles 1 1 is activated by a user.
  • a dosing device 14 is positioned in-line with supply line 10, between supply pump 9 and nozzles 1 1 , to introduce (dose) a coagulant 15 into clean wash fluid 8 as it flows through supply line 10, prior to it being delivered to nozzles 1 1.
  • Dosing device 14 automatically introduces a coagulant 15 into clean wash fluid 8 as it flows through dosing device 14, thereby mixing coagulant 15 with clean wash fluid 8.
  • a suitable dosing device 14 is a Dosatron brand device that is powered, or operably driven, by the flow of clean wash fluid 8 through it. The Dosatron device having a model number DI 1500 is particularly well suited to this application.
  • Dosing device 14 draws coagulant 15 from a coagulant reservoir 16 through a tube 17.
  • Dosing device 14 introduces coagulant 15 into clean wash fluid 8 at a rate substantially proportional to the flow rate of clean wash fluid 8 through dosing device 14.
  • Dosing device 14 is adjustable to vary the rate that it introduces coagulant 15.
  • wash fluid 18 that is contaminated with waste washed off the equipment.
  • Contaminated wash fluid means that the wash fluid is in a "contaminated state”.
  • the "Contaminated wash fluid” is also known as "wash-water” in water based cleaning systems.
  • wash trays 4 Each wash tray 4 includes a removable perforated panel 19 that the contaminated wash fluid 18 passes through. Perforated panels 19 can be used to support equipment being washed and they capture larger solid waste.
  • the contaminated wash fluid 18 collected by wash trays 4 passes through a collection filter to capture solids or heavier waste in the contaminated wash fluid 18.
  • the collection filter comprises a set of three weir trays 20 within each wash tray 4.
  • Contaminated wash fluid 18 flows into the open top of weir trays 20, and the heavier solids settle to the bottom of weir trays 20 whilst the remaining contaminated wash fluid 18 flows over the edges of weir trays 20.
  • Weir trays 20 are removable to clean out waste collected by them.
  • Collection tank 22 is in fluid communication with wash trays 4 by means of contaminated wash fluid 18 flowing from wash trays 4 to collection tank 22 via weir trays 20. Collection tank 22 sits within enclosure 2 above supply tank 7. Collection tank 22 includes an upper level switch 23 that triggers when the fluid level in collection tank 22 reaches a predetermined upper level, and a lower level switch 24 that triggers when the fluid level in collection tank 22 drops to a predetermined lower level.
  • a second pump namely return pump 25, is connected to an outlet 28 near the bottom of collection tank 22.
  • Contaminated wash fluid 18 is held in collection tank 22 until it reaches the upper level and triggers upper level switch 23, which signals return pump 25 to automatically start pumping contaminated wash fluid 18 from collection tank 22. Pumping continues until the level in collection tank 22 drops to the lower level and triggers lower level switch 24, which signals return pump 25 to stop.
  • Return pump 25 pumps contaminated wash fluid 18 through a return filter system to deliver it back to supply tank 7.
  • the return filter system comprises four return filters 26 connected in parallel by a manifold 27.
  • Each return filter 26 is a pressure vessel type filtration unit containing a filtration media.
  • a suitable filter for return filters 26 is the "Flowline II" stainless steel bag filter made by Eaton. Returns filters 26 substantially remove the waste
  • the method of introducing coagulant 15 into the wash fluid in its clean state 8, before it is directed onto the equipment to be washed, has been found to be particularly effective at efficiently and quickly coagulating the waste in the contaminated wash fluid 18.
  • a further advantage of introducing the coagulant 15 into the clean wash fluid 8 before it reaches nozzles 1 1 is that the coagulant 15 is well mixed with the wash fluid 8. Also, the dosing device 14 operates more reliably, and is easier to service, with clean wash fluid 8 flowing through it.
  • the now clean wash fluid 8 is returned to supply tank 7 via another manifold 29 and a return line 30. In this manner, the wash fluid is recycled through the system.
  • Pressure switches 32 and 33 at the inlet and outlet respectively of filters 26, and a throttle valve 34 in return line 30 are used to check whether filters 26 are blocked and need to be emptied or have the filtration media changed.
  • Throttle valve 34 creates a back pressure in return line 30 that varies with the flow through return line 30. The pressure drop across filters 26 increases as they become blocked.
  • a light tower 36 on top of enclosure 2 indicates the state of filters 26. When light tower 36 is green it indicates that filters 26 are not blocked, and washing apparatus 1 may be used. When light tower 36 is orange, this indicates that filters 26 are becoming blocked and will soon need to be changed. When light tower 36 is red, filters 26 are blocked and the system stops.
  • return pump 25 operates intermittently by means of level switches 23 and 24, it is possible to continue to wash equipment whilst changing or cleaning filters 26, with return pump 25 stopped, providing the level in collection tank 22 does not exceed the upper level.
  • coagulant may be introduced into the wash fluid when it is in a contaminated state (instead of when it is in a clean state).
  • Means other than a Dosatron brand dosing device may be used to introduce coagulant into the contaminated wash fluid.
  • a positive displacement pump such as a peristaltic pump, positioned to introduce coagulant into a line between the outlet of the collection tank and the inlet of the return pump, as the contaminated wash fluid flows through this line.
  • Baffles in the line may be provided to assist the coagulant to mix with the wash fluid.
  • the positive displacement pump may be set to deliver coagulant at a constant flow rate proportional to the flow rate of the return pump.
  • Such a system, or other not shown dosing means, may also be used to introduce coagulant into the wash fluid in its clean state.
  • the washing apparatus may have other than two wash trays 4 and two nozzles 1 1.
  • a simpler system may have only one wash tray 4 and one nozzle 1 1.
  • the return filter system may comprise other than four filters 26, or the filters may be arranged in series instead of parallel.
  • the filters may be arranged in series with progressively coarsening filters, or only one or two filters may be used in simpler systems. Also filters other than of a pressure vessel type may be used.
