Description

The The invention relates to a cleaning system for the production of permanent natural waters.

In usual Cleaning systems for swimming pools is in a photochemical-mechanical circulation in the pool located water with a circulating pump over a Skimmer sucked into a pipe and after a photochemical UV irradiation over one another line pressed into a sand filter. In the sand filter is the Water mechanically from turbidity cleaned and then over a another line returned to the swimming pool by means of inlet nozzles.

The conventional Cleaning is usually done with the addition of chemical substances (e.g. Chlorine compounds) used in pelvic cleaning.

The Function of the flow the swimming pool takes over the circulation circuit, wherein rough foreign bodies and finer suspended solids are removed.

One The problem is that although optically clear water is generated, but a reduction of parameters such as coliform bacteria, plant nutrients how phosphorus and nitrate are limited. Thereby can the quality the water is not permanently guaranteed in view of these parameters become. An algae growth would adjust within a short time and to a considerable optical impairment lead the water. Also, by doing without the addition of chemical substances a health damage of the human organism, especially during bathing become.

Other conventional Cleaning systems based on reduction processes in a regeneration tank especially in swimming pond systems are limited to the cleaning and the nutrient withdrawal of the bathwater exclusively in that biologically, mechanically and / or photochemically treated Water from the regeneration area directly back to the swimming area supplied will or ever no separation between swimming and regeneration zone.

One The problem is that such a system permanently no adequate water clarity and purity of the swimming area in the The meaning of the swimming pool and bathing water regulation, because the conventional Cleaning system does not withstand changing environmental conditions only by a large dimensioning of individual items that do not look at an average lot size is feasible, approximate can be achieved. The nutrient and pollutant content in the water corresponds to conventional Type of natural water basins approximately the accompanying material content in the water of the regeneration area.

It is a pool system for swimming and / or bathing purposes and a measuring and control device for ensuring the quality of water for such a pool system in the document DE 100 29 568 A1 described, wherein the pool system includes at least one swimming pool, which are associated with a Wasserumwälzkreis, a water extraction device with a connected measuring and control device and metering devices for the addition of disinfectants, such as chlorine. The circulating circuit essentially contains a water tank downstream of the splash tank and a sand filter through which the pool water is guided and cleaned and fed back to the pool. On the way to the pool, chemical substances for disinfection are supplied to the supply line by means of interposed metering devices in compliance with the hygienic safety regulations for the water quality, eg DIN 19643.

For each Pool is provided a pelvic flow, the one Discharge of polluted water from the pool through an overflow in the cache for provides the splash water and with a circulation of the Pool water is achieved by means of a Wasserumwälzanlage. The Water circulation system contains one Water circulation pump, the overflowing, Trapped water through a water treatment plant in the Essentially at least one flushable Contains sand filter, suppressed, the treated water flows back into the water basin. to After adjustment, appropriate amounts of chemicals are metered in the water circulation circuit given.

One The problem is that the water treatment device preferably Dosing devices for Contains chemicals, The regulated according to the measurement results and / or accordingly be controlled and initiated in advance by presets with fixed values.

For such reprocessing plants, the photochemical-mechanical filter systems for water can be used, which in the document DE 199 50 064 C2 are described. The filter systems contain a filter container in which sand is also introduced as a filter substance, an inlet and an outlet through which the dirty water to be purified from the water basin is passed through, as well as a UV radiation disinfection device for germs, at which the water is bypassed.

One Problem is that the water treatment only up to one can be done to a certain degree. A water quality with a relatively lower Minimum of accompanying substances is not achievable.

It is further associated with a primary Wasserumwälzanlage a pond system, which in the document DE 101 28 930 B4 is described. The pond complex includes a main pond for swimming and bathing and a secondary pond, which is intended to clean the main pond. The water level of the secondary pond is below the water level of the main pond, so that water from the main pond can flow as an overflow to the adjacent pond. The secondary pond contains a concrete-encased bottom seepage filter with a filter layer consisting of a coarse gravel layer, a fine gravel layer, a non-woven layer and a sand layer towards the pond surface. The suctioned through the filter layer and thereby filtered water of the basic precipitating filter is fed back to the main pond via a pump.

One Problem is that here only a rough cleaning of impurities of the water from the main pond by means of the seepage filter in the Secondary pond performed can be.

It is also a method for the biological and biochemical treatment of water, preferably of pool water, in the document DE 101 29 663 A1 described. The filter system also contains at least one sand filter, furthermore an ionization device, a downstream activated carbon filter and a titanium oxide granulate cleaning filter with built-in UV disinfection device. The process is carried out by feeding an ionized and ozone-enriched air stream in the activated carbon filter to promote oxidation in the activated carbon filter, and then subjecting the water stream to photochemical and photocatalytic oxidation in a reactor which is exposed to UV-C radiation. Emitter and formed with UV-C radiolucent tubes, the tubes are partially filled with a titanium oxide granules. The titanium oxide granules are held in suspension as they flow through the water. In conjunction with the UV radiation, the catalytic oxidation is triggered. The process-induced ozone generated in the reactor is introduced into an ionization module and dispersed as radicals in the water stream before the activated carbon filter.

One The problem is that the entire cleaning system is too materially and costly.

A nano-filtering device and a reverse osmosis system for treating the water of water basins in a semipermeable membrane filter system for swimming pools is in the document US 5,234,583 A described. This eliminates organic and inorganic particles.

The Problem is that due to the existing floating larger accompanying substances in the Water, the membranes are quickly clogged and therefore very often need to be cleaned. Of Further, the concentrate from the rinsing processes of the membrane filter not a closed circuit, but a drain supplied.

Another plant for the treatment of bath water from a swimming pool in the circulation process is in the document DE 202 08 814 U1 The plant has a first filter system for filtering the pool water associated with a swimming pool, a second filter system in the form of a membrane filter for filtering sludge water from the first Fil teranlage and a return of filtrate from the second filter system in the bath water circuit, wherein the first filter system also contains membrane filter and the second filter system is connected to the supply line for bathing water, that the second filter system can be used at least partially for the filtration of bath water.

One Problem is that the arrangement and design of the filter systems is too expensive and only the reduction of toxic Accompanying substances. At the end of the process become the bathwater again added chemical disinfectants.

A system for purifying water, in particular chlorinated bath water in a swimming pool, is in the document EP 1 042 237 B1 described. The cleaning system comprises a sand filter assembly, a photochemical treatment UV system, and means for maintaining circulation of water along a tubing and through the filter assembly for filtering the water and means for diverting a first substream from the stream of filtered water through the sand filter assembly and Passing the first substream along a first partial strand and through the UV system for photochemical treatment. There are means for branching a second partial stream of the photochemically treated water from the first partial flow and for passing the prepurified water along the second partial strand of the second partial flow and there is a membrane filter assembly in which compounds dissolved in the water, such as salts, are removed whose filtered concentrate disappears into an outlet.

One Problem is that relatively many flushes of the sand filter device and the membrane filter assembly due to the direct removal of Water from the swimming pool must be done as well the mud concentrate the membrane filter assembly no appropriate use for further direct or indirect training of filtering processes.

Using several cleaning basins is a method for purifying wastewater using plants in the document DE 3 244 787 A1 described, wherein the roots of the plants bind in cooperation with soil substrates and microorganisms contained in the wastewater and degrade. In the method, the wastewater is introduced from an area below the roots into an area above the roots. The wastewater is passed evenly through the roots. The roots form with the gravel from the wastewater in a vertical direction from bottom to top flowed through filter and absorption layer. The gravel is on a grid, which is flowed through by the sewage in the upward direction. If the sewage contains chlorine compounds, the existing plants in the basins are damaged.

One Problem is that for a complete Cleaning the wastewater at least one pre-cleaning tank, a Main cleaning basin and at least one post-cleaning tank required are, which means a lot of effort to a relatively clean To obtain filtrate from the wastewater. Despite several subordinate Filter basin may be in use after dispensing the filtrate of the filtrate develop and spread algae growth.

A method for treating the water contained in the pool of a public swimming pool is in the print font AT 30 229 E described in which water is continuously withdrawn from the tank to direct it into a treatment tank, wherein the water is withdrawn from the treatment tank to bring it into contact with semipermeable membranes of a separator, wherein the membranes have a separation threshold of more than 5000 wherein the fraction of water which has not passed through the semipermeable membranes is returned to the treatment tank and the water fraction which has passed through the membranes is returned to the tank and the average relative pressure of the liquid flowing in the first part of the separator Water between 0.4 and 20 bar and wherein the speed of the coming into contact with the membranes in the first portion of the separator water between 0.3 and 5 m / s.

there there is also an addition a chlorine-containing disinfectant to the pool water to the Pool water at a certain degree of biological purity in terms of pollutions to be obtained by pool users because the sterile ultrafiltered water, which comes from the separator, free from all bacteriological seedlings is. Chlorine gets over a tube introduced.

One The problem is that chlorinated bath water is also present here with the chlorine avoiding algae growth in the pool should. But it is flowing in the leading to the processing tank tube other Part of the water over a valve either directly or through an air supply device through into the treatment tank guided. Through the cycle over that after the preparation tank connected and leading to the separator pipe and after the separator to the treatment tank to lead de Rohr will spoil the water in the treatment tank over time. By supplying air by means of the air supply device in Area of the recycling bin leading Pipe and / or by means of a compressed air supply in the area leading to the separator Rohres are only the high accumulation of foreign substances in the frame delays the process of rejuvenation, but no foreign matter eliminated.

Of the Invention is based on the object, a cleaning system for the production permanently natural waters indicate that is designed so that a provision of high quality pure water without the addition of chemicals by means of a mechanically-selective filtration for activation biological repositioning processes in a closed overall circulation system he follows.

The The object of the invention is characterized by the features of the claim 1 solved.

That for the reverse osmosis subcircuit 13 branched, provided prepurified water from the line 40 is via a pressure pump 43 at a pressure of 7-15 bar in the reverse osmosis filter system 14 pressed. The pre-cleaned water is in the reverse osmosis filter system 14 thoroughly cleaned by the reverse osmosis process and via the second return line 54 discharged and over the inlet 16 as pure water filtrate 17 the swimming pool 3 fed. This is due to a required flushing of the reverse osmosis filter system 14 resulting flushing concentrate 15 passes through the flushing concentrate line 44 into the horizontal water surface bonded flow filtration system 9 of the regeneration tank 39 ,

The horizontal surface-bound water flow filtration system 9 may contain one or more source stones (water features, streams, etc.) and a second skimmer 45 , which is the water of the flow filter 7 through the pipe of the overflow 10 into the water reservoir 5 dissipates. To the horizontal flow filter system 9 can also the flushing concentrate line 44 be calculated, wherein the exiting flushing concentrate on the surface side of the filter substrate of the flow-through 7 is distributed.

Possible water losses in the cleaning system 1 be in the water reservoir 5 about a water supply 46 that have a regulatory system 47 can be controlled, balanced. The possible excess of water, caused for example by high rainwater precipitation, accumulates in the water reservoir 5 and can through the line 48 a third overflow 49 in the process 29 be dissipated. Furthermore, the rinse water of the sand filter 25 . 36 over the wires 28 . 50 in the process 29 dissipated.

In place of the process 29 can the nutrient-enriched water 30 from the water reservoir 5 also be delivered to an irrigation system for vegetation areas.

The following is the summary of the operation of the cleaning system according to the invention in summary 1 explained in more detail. In the first stage pool-associated photochemical-mechanical recirculation loop 4 it will be in the pool 3 located bathing water 2 with a first circulation pump 18 with a suction pressure of 0.5-1 bar over a first skimmer 19 in a line 20 aspirated and after a photochemical UV irradiation by means of a first UV irradiation device 21 over the wires 22 and 23 in a first sand filter 25 pressed. In the first sand filter 25 becomes the bathwater 2 mechanically cleaned of turbid substances and then over the line 26 back in the pool 3 by means of inlet nozzles 27 recycled. The flushing line 28 of the first sand filter is to the process 29 guided.

That in the second-stage Biosafety Selection Activator cycle 51 belonging water reservoir 5 located water 30 becomes in the flow partial circuit 11 pre-filtered. A part (about 85%) of it is directly over the vertical ground-based Durchströmungsfiltersystem 8th in the filter substrate 42 of the regeneration tank 39 and thus into the root area of the reposition plants. The water then runs into the water reservoir 5 over the second overflow 10 back and the circulation in the flow partial circuit 11 to be continued.

In the regeneration tank 39 Be the over the reverse osmosis subcircuit 13 supplied accompanying substances-nutrients and pollutants- via the flushing concentrate line 44 degraded by a conversion into biomass. The remaining amount of water from the outlet pipe 37 in the amount of about 15% of the circulation capacity of the flow-through partial circuit 11 be over the second branch line 40 the reverse osmosis subcircuit 13 through the pressure pump 43 fed. Approximately 80% of the water from the second branch line 40 flow to the reverse osmosis filter system 14 via the flushing concentrate line 44 into the horizontal water surface bonded flow filtration system 9 wherein the mud concentrate is substantially above the filter substrate 42 is distributed for absorption by the reposition plants. The remaining approximately 20% of the water from the second branch line 40 be as pure water filtrate 17 over the inlet 16 in the pool 3 guided and help as a result of mixing with the existing bathing water 2 to constantly mince its accompanying substances.

The invention makes it possible that the nutrients and pollutants from the bathwater 2 targeted by the first overflow 6 into the water reservoir 5 removed and from there from the regeneration basin 39 over the flow-through partial circuit 11 fed and controllable against incoming pure water filtrate 17 from the inlet 16 is exchanged. There is therefore a selection with the goal, which takes place in the bath water 2 unwanted accompanying substances from the swimming pool 3 filter out and targeted the biodegradation process in the biological-mechanical selection activator cycle 51 supply. The process is realized in that in the reverse osmosis subcircuit 13 On the one hand, ultrapure pure water filtrate (so-called permeate water) for the swimming pool 3 and on the other hand, rinse concentrate 15 with supply to the horizontal flow filtration system 9 will be produced.

The biological-mechanical selection activator cycle 51 forms the basis for the reverse osmosis subcircuit 13 as part of a wholeness cleaning system 1 without draining the flushing concentrate 15 in the process 29 can be performed and the pool 3 the pure water filtrate 17 is supplied as so-called permeate water. On the contrary, by feeding the mud concentrate 15 into the flow-through filter 7 its filter properties are stimulated and improved, thus increasing the environmental friendliness of the overall filter system.

The invention with the biological-mechanical treatment of the flushing concentrate 15 combined with a permanent reduction of nutrients and pollutants in the regeneration basin 39 Also prevents a continuous increase in the concentration of unwanted accompanying substances of the water 30 in the water reservoir 5 ,

The invention thus also opens the possibility that in areas with relative water scarcity or fluctuating water supply the permeate water as drinking water permanently available is available. Since it does not matter from which sources the water supply 46 into the water reservoir 5 takes place, via the cleaning system according to the invention 1 accordingly also drinkable water from precipitation water, well water oa. be provided if necessary.

The invention thus ensures a permanently clear and clean bath water 2 in the pool 3 without water loss in the entire cleaning system 1 , A possible water loss results exclusively from splashing water loss during bathing or from natural evaporation.

The water basin 3 may optionally be designed both as a firmly enclosed swimming pool as well as a swimming pond system with a swimming area and as a water reservoir.
