Definitions
- the invention relates to a method for providing or
- the contaminated water used in a water treatment or cleaning system via at least one sludge separator and at least one oil separator for separating gasoline and mineral oil in floating form or in the form of droplets in at least one buffer tank ⁇ container is guided, from which the water is removed for the washing processes, and the contaminated water is also subjected to a filtration in the course of the treatment.
- the invention relates to a water treatment or cleaning system, preferably for washing systems for vehicles with at least one washing device, e.g. Brush washing machine, which is supplied with recycled water from at least one pump, the contaminated water being led via at least one sludge separator and at least one oil separator for petrol or oil in floating form or droplet form into at least one buffer container from which the water can be used again is withdrawn with the pump, and wherein a filtration device for the water is provided.
- washing device e.g. Brush washing machine
- the method is now the starting point mentioned type provided that .das the water from the buffer tank without the addition of flocculants, especially salts, before using the water for washing processes of a (fine) filtration to filter out the floating, oil-contaminated dirt particles or the floating, contaminated Oil particles are subjected and this is filtered in this way, the water which still contains the substantially stable emulsified residual oil constituents is used in particular directly for washing processes or in automatic washing machines or systems, at least one washing process, preferably the pre-wash and / or main wash, is filtered with this Water takes place.
- a system of the type mentioned at the outset is characterized in accordance with the invention in that, at the same time as there is no flocculation system between the buffer tank and the washing device and / or an optionally provided collecting tank upstream of the washing device, at least one (fine) filter device for filtering out is arranged in the water (emulsion) entrained or floating oil-contaminated dirt particles or oil residues mixed with dirt, and the water from the buffer tank is fed directly to the (fine) filter device with the pump.
- At least one (paper) leaf filter with a permeability of at most 30 ⁇ , preferably at most 15 ⁇ , in particular at most 5 ⁇ , is provided as a filter in the filter device, since this ensures sufficient purification of the water is aimed and especially when using these (paper) leaflet filters a particularly long filter service life and good separation efficiency resulted.
- the procedure is particularly environmentally friendly if the free or undissolved or unbound or unstably emulsified oils in the oil separators, which are preferably designed as residual oil separators, in particular corrugated plate separators, up to a value of maximum 20 mg / 1, preferably maximum 10 mg / 1 , be deposited. If the buffer tank is not connected to a sewer, but rather the water is only circulated, these values have proven to be advantageous for performing good quality washes.
- the invention provides that the water passing through the water treatment system is mixed with ozone, in particular for bacterial destruction, or that it is placed in the water circuit, preferably in a water line leading from or before the buffer tank bypass line branched off from the filter or at least one ozone generation device is connected or connected to a branched line leading into sludge separators, the residual oil separator or the buffer tank.
- a supply line for fresh water and a supply line for recycling water to the washing device are provided, with a shut-off or switching device, e.g. a 3-way tap is provided, with which the line for recycling water can be connected to the line for fresh water, and when the fresh water is switched off, the recycling water can be fed through the fresh water line in the washing device, the switching or shut-off device preferably being provided by a water level meter is controlled in the buffer tank.
- a particular aspect of the invention is the use of paper flake filters with a permeability of at most 10 ⁇ , preferably of about 5 ⁇ , for the filtration of recycling water and separation of oil dirt particles in water treatment systems, in particular for motor vehicle washing machines, which water from entrained dirt particles, e.g. sand, which are carried along , and free or undissolved or unstably emulsified oil particles are pre-cleaned or freed.
- Such paper flake filters are known per se for the cleaning of kerosene and hydrocarbons in order to remove dirt particles contained therein.
- FIG. 1 shows a schematic of a washing installation according to the invention
- FIG. 1 shows a schematic detail of the installation according to the invention.
- the invention is based on a washing system for
- one or more conventional washing devices (e ⁇ ) 10 which are provided with brushes, and / or customary washing stations, are fed via a feed line 11 for recycled water and via a fresh water separation system 27, a pump 4 ′ and a feed line 12 supplied with the necessary wash water for fresh water.
- the usual car washes include a pre-wash, a main wash and a post-wash. It is known to do the washing with recycled water; According to the invention, all washes can be carried out with recycled water (if available sufficiently), the water to be recycled being added with no solid or liquid chemical flocculants to flocculate oil-containing impurities, the reaction products of which would have to be disposed of.
- wash water is fed to the washing machine 10 via line 11, optionally via an expansion tank or storage tank B, at a pressure created by pump 4 or preferably by submersible pump 31 via line 11.
- wash water can thus be supplied via the fresh water line 12 or via the lines 11 if required.
- the contaminated wastewater containing sand and oil is collected in a rig 13, 13 'and fed via line 14 to a sludge separator 1 designed as a settling tank.
- This sludge separator has a diameter of approximately 2.5 m and has a capacity of 5 m 3 .
- the overflow water is fed via line 15 into a residual oil separator 2 (according to DIN 1999 Part 3 or ⁇ NORM B5101) in which the free and floating oil and petrol particles are separated.
- this residual oil or corrugated plate separator 2 prevents more than 20 mg / 1, in particular more than 10 mg / 1, of free dissolved and unstably emulsified gasoline or oil components in the
- volume 3 is connected to a channel, has a volume of about 1.8 m; if the system is operated with a washing machine in a closed circuit, the volume of the buffer tank is approximately 5 m.
- the water is drawn off via a line 17 with a pump 4, the pump 4 being actuated by corresponding control devices 18 and having a wind boiler 25.
- the pump 4 presses the water drawn off from the buffer tank 3 through a filter device 5, optionally via a storage tank 6, to the washing system 10.
- a submersible pump 31 can also be provided in the buffer tank 3.
- the filter device 5 comprising at least one filter unit comprises, on a filter tube 29, paper flake filters 28 which have a permeability for particles of up to 30 ⁇ m, preferably up to 15 ⁇ m, in particular only up to 5 ⁇ m in size.
- the oil-contaminated floating particles or dirt-containing oil particles contained in the recycled water are separated, so that the washing system 10 is supplied with recycled water which only contains the emulsified oil residues.
- these emulsified oil residues showed no influence on the washing behavior of the recycled water. Rather, it was found that by dispensing with flocculants or precipitation chemicals for detergents and shampoo, a longer service life was achieved for the washing device 10, since the addition of flocculants led to signs of rust on the washing device.
- recycled water also means that the water contains a certain proportion of detergents and shampoo, so that the shampoo addition to the amounts of water required for the individual washing processes can be minimized or switched off, as a result of which the process is carried out in a more environmentally friendly manner. It has been shown that by dispensing with flocculants, which cause acidification and salting of the recycled water, the plant can be used for almost any purpose many washing processes can be operated in the circuit without water having to be added or exchanged. This can take place as long as the buffer tank 3 is sufficiently filled, ie the water losses due to evaporation and discharge do not make it necessary to supply fresh water. It can be seen that, despite dispensing with a fresh water supply, the polluted water could be cleaned sufficiently well and recycled again for use.
- a water level meter 9 is arranged in the buffer tank 3 and is provided to indicate a minimum water level in the buffer tank 3. If the minimum water level is displayed, a shut-off device 20 opens upon the signal from the water level meter 9 or the control device 18, and fresh water is supplied from the fresh water separating device 27 via a pump 4 'into the drain 13 or into the sludge separator 1 or the buffer tank 3 via a water supply line 19 fed until a certain water level in the buffer tank 3 is reached.
- the buffer tank 3 there is also a level control 8 with a maximum and minimum water level meter 8. If the water level is between these measuring points, the washing, in particular the washing with fresh water, is carried out, since excess water can be taken up in the buffer tank 3. If the water level in the buffer tank 3 reaches the upper measured value, the supply line 12 for fresh water is switched off or, by appropriately switching over the fresh water line 12, recycling water is supplied for the after-washing, so that all washes are then carried out exclusively with recycling water. When the water level in the buffer tank 3 has dropped to the lower level due to evaporation and discharge, the supply and use of fresh water for washing again takes place.
- valves in particular three-way motor ball valves 21, are provided in order to supply the recycling water through the fresh water feed 12 to the washing device 10 when there is a signal from the level control unit 8 which indicates a maximum water level in the buffer tank 3.
- level control unit 8 which indicates a maximum water level in the buffer tank 3.
- shut-off devices gene 20 can fresh water via the inlet rig 13 or
- the recycling system is put into operation or the water is circulated even during downtimes of the washing system or at night.
- Water is fed into the drainage system 13 or directly into the sludge separator 1 via a line 22, which can be shut off with a valve 23, from the filter device or from the storage container 6, if present, or from the line downstream of the filter device 5.
- the shut-off device 23 is controlled by an electrical timer circuit of the control device 18. A part of the water is drained off via this line 22 and the total water is circulated by appropriately controlled operation of the pump. If necessary, a bactericide can be added to combat bacteria in shock at higher outside temperatures.
- the level switch 9 in the buffer tank 3 provides that in the case when there is little or no water in the buffer tank 3, e.g. by entrainment of water, evaporation or when the system is started up, an impulse is given to the solenoid valve 20, which opens the fresh water supply line 19 to the inlet trenches 13 or 13 'or the sludge separator 1 until sufficient water in the sludge separator 1 , is present in the corrugated plate separator 2 and in the buffer tank 3, ie until the maximum water level is reached.
- the water is extracted using the pump 31 or the pump 4, which are activated by the control circuit 18. With the pump 4 or 31, a pressure of about 6 bar is built up, with which the water is pumped through the filter device 5.
- the filtering device 5 it is entirely possible to implement the filtering device 5 by means of several filters connected in parallel.
- the sludge separator 1, the residual oil or corrugated plate separator 2 and the buffer tank 3 can be realized by a series of units arranged in parallel or in series, a parallel arrangement being preferred because of the more uniform separation.
- the device according to the invention is also connected to a plurality of washing units 10 or washing stations or the like arranged in parallel. adaptable; if the accumulation of dirty washing water is greater, the system can - as mentioned - be designed for larger capacities by means of units of sludge trap, corrugated plate separator, buffer tank, pump, filter, consumption memory etc. connected in parallel or of a larger size.
- the pump 4 or 31 is arranged between the buffer container 3 containing water that has been freed of oil residues and the filtering device 5, since when the pump is operated with the pump wheel no oil particles can be broken up and freely distributed in the water, so that Separation effect of the residual oil separator 2 is considerably supported.
- the collecting container ß can be omitted and the line 17 can pass directly into the line 11, which simplifies the construction of the system.
- the Frischwassertren ⁇ anlagen 27 are provided in order to ensure that in the event of damage in shut-off valves that no water can penetrate from the system into the public water supply network. It is particularly advantageous if the circulated water is mixed with ozone from a known ozone generation device 2fi, with more than 0.2 mg and up to 2 mg, preferably up to 1.6 mg, ozone / m 3 in the flowing water can be introduced.
- the ozone generating device 26 can be connected directly to a water-carrying line 11, 14, 15, 16, 17; preferably it is connected to line 33; In order to be able to supply the water with ozone even during downtimes of the washing system 10, lines 33, 34 connected via motor ball valves 21 'are provided which return the water to the sludge separator 1 or the buffer tank 3 and to or into which the ozone generating device 26 is connected.
- the control unit 18, which regulates the operation of the ozone generation devices 26, can thus carry out a specific water flow or cycle even when the washing system 10 is at a standstill or at night, in order to enable a uniform supply of ozone during predetermined periods in a predetermined dose.
- the line 33 is connected to the drain connection 30 or to a motor ball valve of the filter units 5 provided at this point, so that the filters flow through the water 28 are rinsed or cleaned and the sludge retained by the filter 28 or in the filter housing can be mixed with ozone or broken down and rinsed into the sludge separator 1.
- the filters 29 are again or completely filtered and the water supplied to the washing system 10 is filtered.
- the motor ball valves 21 'and 30 part of the water flowing through the lines can thus be drained off or this water can be completely diverted. An ozone supply can thus also take place during the washing process.
- the ozo generator 26 can also be connected to a bypass line 32 in order to divert part of the water flowing through during operation and to add ozone.
- the ozone is fed into the water circuit by means of an ector line 35, from which the ozone formed is sucked off from the flowing water.
- a cyclone 40 in the line 17 in front of the filtering device 5 as an additional filter device for contaminants, the dirt discharge 41 of which opens into the line 14 or into the sludge separator 1.
