    15 20 25 30 35 flows through the system, which means that no extra energy needs to be supplied to drive the water in the right direction.
    In one embodiment, the second tank is connected to an inlet of the washing machine so that the carpet washing system forms a closed system. The closed circuit means that the washing water can be reused, that the system can be more or less self-sufficient, and that the water temperature can be kept relatively constant during the entire purification process, thus saving both energy and water. Furthermore, the closed circuit also helps to ensure that unpolluted water is pumped out into the environment.
    In an alternative embodiment, the carpet washing system comprises a rainwater tank for collecting rainwater, where the rainwater tank is connected to an inlet of the separation tank. When new water needs to be added due to that water evaporates from the circuit, this is taken from natural rainwater that has been collected in the rainwater tank, which is an advantage as the rainwater can be collected from the environment where the carpet washing system is arranged, which leads to even more energy savings when e.g. resources from the immediate area are used.
    In a further alternative embodiment, the separation tank, the bacterial tanks and / or the rainwater tank comprise insulation to keep the water temperature as high as possible. An advantage of this is that no or a very small amount of energy needs to be added to heat the water before the next wash.
    In one embodiment, the saturation washing system further comprises an air pump for oxygenating the water in at least one of the tanks which purifies the water by means of bacteria.
    The supply of air is advantageous because the purification of the water becomes even more efficient and the water even cleaner.
    BRIEF DESCRIPTION OF THE DRAWINGS Embodiments of the present invention will be described in more detail with reference to the accompanying drawings, in which: Fig. 1 shows a system for purifying water from a carpet washing process.
    DETAILED DESCRIPTION OF EMBODIMENTS The embodiments shown will now be described in more detail with reference to the accompanying drawings. However, the invention may comprise many different parts and is therefore not limited to the embodiments shown, but these are seen more as examples of the invention.
    Fig. 1 shows a carpet washing system 10 according to an embodiment which purifies the washing water in an energy-efficient manner, after a carpet washing process, so that the water can be reused for your washes. The carpet washing system 10 comprises at least one washing machine, in this case two identical washing machines 20a, 20b which wash carpets. Usually a washing program is run in one washing machine 20a, 20b at a time, but it is also possible to run the two washing machines 20a, 20b at the same time. The system 10 further comprises a separation tank 30, a first bacterial tank 40a, a second bacterial tank 40b and a third bacterial tank 40c in which the washing water flows through and is purified in various ways.
    In the separation tank 30, the washing water is separated from sand and gravel by letting the sand and gravel fall down to the bottom 31 of the separation tank 30. The bottom of the separation tank is preferably formed as a slope down towards one side of the walls of the separation tank. In Fig. 1, the bottom slopes down towards the right bottom part 32 of the separation tank 30 because the washing water, as it flows in from the upper, left part 33 of the separation tank 30, naturally creates a stream of water which leads the sand and gravel down to the right bottom part 32. a right bottom part 32 is an emptying line 34 in which sand and gravel can be emptied out if necessary. In another embodiment, the bottom part of the separation tank can be designed as a cone where the lowest point, where the emptying line is arranged, is instead located in the middle of the bottom part.
    The first, second and third bacterial tanks 40a, 40b, 40c are tanks which purify the washing water by means of bacteria, for example of the bacterial compositions 1010 and 1425 which are commercially available from the manufacturer HTS BIO. The bacteria are of the same type as those found in natural watercourses but are adapted to eat certain types of dirt. They are preferably fed with nutrients once a week and it is suggested that nutrients be added in connection with a cleaning or emptying of the bacterial tanks 40a, 40b, 40c. In each bacterial tank 40a, 40b, 40c, a bacterial device 41a, 41b, 41c is provided for the well-being of the bacteria. Furthermore, a backflow pipe 42 is arranged between the third bacterial tank 41c and the second bacterial tank 41b for recirculation of the washing water. The recirculation takes place, for example, through a bilge pump 43 and by recirculating the water from the third bacterial tank 40c to the second bacterial tank 40b, bad odors in the water are reduced or eliminated so that it can be reused in further washing processes.
    In an alternative embodiment, the system may comprise fewer or more bacterial tanks. All types of tanks in the system are preferably cast in concrete and provided with an insulation to keep the water temperature relatively constant.
    In a further alternative embodiment, the carpet washing system may comprise a volcanic gravel filter, arranged after the purification in the bacterial tanks. As the wash water flows through the volcanic gravel filter, bad odor from the water is eliminated. The volcanic gravel filter may be an alternative to the backflow pipe in Fig. 1.
    Furthermore, an air pump 44 is connected to one or more of the bacterial tanks 40a, 40b, 40c for oxygenating the water in the tanks. Addition of oxygen to the water makes the purification process even more efficient and the bacteria can thrive. The air pump 44 may also be connected to other parts of the system 10, e.g. the separation tank 30 when extra oxygen supply is required.
    The carpet washing system 10 may also include a particle filter 50 provided in the system 10 before the water again reaches the washing machines 20a, 20b. The particle filter 50 is not necessary to have in the system 10 but can be good when you want to be completely sure that the last particles have really been filtered out.
    System 10 is a closed system where up to 98% of the water is reused, with the rest evaporating or accompanying when emptying the tanks. To fill the system 10 with fresh water, the system 10 also comprises a rainwater tank 60 which is connected to the separation tank 30. The rainwater is collected from roof surfaces (not shown) near where the carpet washing system is located, via gutters, downpipes (not shown) and to close a water pipe 61, down into the rainwater tank 60.
    The various parts of the system 10 are connected to each other by means of one or two water pipes, which are also shown in Fig. 1. From each washing machine 20a, 20b run a first and a second water pipe 70a, 70b which are then connected in a third water pipe 70c. The third water line 70c directs the washing water from the washing machines 20a, 20b to the separation tank 30. Furthermore, the water is led further from the separation tank by means of a fourth water line 70d to the first bacterial tank 40a. The fourth water line 70d is preferably inclined at an angle down towards the first bacterial tank 40a so that the water itself can flow down into it. Between the first bacterial tank 40a and the second bacterial tank 40b, and between the second bacterial tank 40b and the third bacterial tank 40c, a fifth water pipe 70e and a sixth water pipe 70f are arranged. The fifth and sixth water pipes 70e, 70f, like the fourth water pipe 70d, are preferably slightly inclined downwards so that the water can flow freely down into the respective tanks 40b, 40c. From the third bacterial tank 40c, a seventh water line 70g directs the water back to the washing machines 20a, 20b by means of a pump P, via the optional particle filter 50. Furthermore, the rainwater tank 60 is connected to the separation tank 30 by means of an eighth water line 70h.
    When the system 10 with the tanks 30, 40a, 40b, 40c, 60 is closed, the water temperature can be kept relatively constant, preferably between 30 ° C and 35 ° C. This means that large energy savings can be made as the water does not need to be heated up very many degrees every time a washing process is to start. When the mats are washed at between 30 ° C and 40 ° C, there is a steam boiler 80 arranged in direct connection with the washing machines 20a, 20b to heat the water, if necessary, the last degrees. The carpet washing system 10 as described above needs approx. 0.45 kW / kg of laundry for heating, which is far below the value required in Sweden for the system to be considered environmentally friendly.
    The washing machines 20a, 20b are powered by natural gas, which also contributes to a more environmentally friendly and energy-saving process.
    In order to be able to efficiently wash a large amount of carpets, it is advantageous to have at least two washing machines 20a, 20b. The washing machines 20a, 20b may in turn be connected to a dryer (not shown) for drying e.g. mattoma. As the drying process takes less time than the washing process, it is advantageous to run the two washing machines 20a, 20b around each other so that even the dryer is always running.
    During each washing process, the washing water is contaminated with dirt and chemicals from e.g. detergent. The carpet washing system described above is well suited for using different biocides instead of detergents, which is a great advantage as the washing process will further improve its impact on the environment. When detergents are used, the system only needs a third as large an amount of detergent compared to systems used today, which means that the amount of chemicals that can affect the environment in a negative way is low.
    The washing water that is to be reused after a carpet washing process goes through a number of steps for purification. First, the washing water flows to a separation tank 30 in which i.a. gravel and sand are separated from the washing water by letting the gravel fall to the bottom of the tank. When fresh water needs to be added to the washing water, this is taken from a rainwater tank 60 which collects rainwater from nearby facilities. The rainwater also passes through the separation tank 30. Furthermore, the water, the washing water and the possible the rainwater, further to a number of tanks 40a, 40b, 40c which all contain a bacterial device where bacteria purify the water from e.g. unwanted particles and dirt.
    Preferably, the water flows freely between the tanks 40a, 40b, 40c by means of water pipes 70d, 70e, 70f which slope slightly downwards towards the next tank. Between two of the tanks 40b, 40c a backflow pipe 42 is arranged so that the water can circulate back to the tank 40b before.
    This procedure proves to be very effective in removing bad odors from the water that would otherwise get stuck in the carpets being washed, which would not be appreciated by those using the carpets. From the tanks 40a, 40b, 40c which purify the water with the bacterial device, the water can be driven up to the washing machines 20a, 20b again when a new washing process is to be started. Alternatively, the water can be driven through a particle filter 50 before returning to the washing machines 20a, 20b, to separate the last small particles from the water. Although the present invention has been described above with reference to specific embodiments, the invention is not limited to a specific system.
    The invention is limited only to the appended claims and thus other embodiments are possible.
