    The invention relates to a bathwater suitable for treatment by means of electrolysis, based on tap water. The invention further relates to a method for producing a bathing water and its use.
    It is common to chlorinate the water in swimming pools or swimming pools (swimming pools) for disinfection, since chlorine already kills germs present in a very low concentration of a few tenths of a milligram per liter in the water. So far, there is no real alternative to disinfecting bath water with chlorine. Organic pollutants in the water are oxidized by chlorine and thereby degraded, with per liter of bath water in public baths between 0.3 mg and 0.6 mg of free chlorine per 20 liters of water are allowed. Only for epidemiological reasons, the concentration may be increased in the short term. In clean water, chlorine only finds the organic substances of bacteria that are killed as reactants. In water with organic pollution, the chlorine also binds to contaminants and forms with these organochlorine compounds. The so-called chlorine amines are formed by combining chlorine with nitrogen compounds, for example from urine or sweat. Chloro-nitrogen compounds are summarized under the term "bound chlorine". The typical smell in swimming pools and the occurrence of eye irritation are due to chlorine amines. A low level of bound chlorine is therefore a measure of good water quality.

    Furthermore, chloro-carbon compounds are formed in the water, especially trihalomethane (THM), which are volatile organic halogen compounds. For trihalomethanes, whose most prominent representative is chloroform (tritlamethane), there is a reasonable suspicion of carcinogenic effects. A guideline for the THM load below which no carcinogenic effect is to be expected is currently not available but should be worked out. As long as damage to human health can not be ruled out, these and other suspicious substances in the bathwater must be considered as hazardous as a precautionary measure and their concentration be limited accordingly.
    The invention has for its object to provide an electrolytically treatable bath water available, which requires no chlorine for disinfection, requires no pH regulation and contains no health-endangering compounds or generated.
    The object is achieved according to the invention by the fact that the bath water contains at least one of the alkali metal ions Na +, K + or Li + in a content of 100 mg / 1 to the saturation limit and its chloride (Cl ') - content that of the underlying
    Tap water is.
    The alkali metal ions contained in the water provide the necessary electrical conductivity for electrolysis. The disinfectants for removing organic contaminants are generated directly from the water by electrolysis. These ions increase the electrical conductivity of the water and buffer the pH to a value around 8 or higher, thus in an optimal range, which does not dry out the skin, but regulates the base balance.
    The process according to the invention for producing a bathwater which can be treated by means of electrolysis and is based on tap water is characterized in that at least one of the bicarbonate compounds NaHCO 3, KHCO 3 or LiHCO 3
    I * t · + «« »* * * * * * *« «* * * * * ··· ·« * «·· ♦ · * i« · «9 r4 3 and / or one of the carbonate compounds Na2Co3, K2CO3 or L12CO3 is metered in such an amount that the conductivity of the water is at least 0.5 mS / cm.
    The bathwater according to the invention is produced once during or immediately after the bathing or swimming pool has been let in and remains in optimum quality over a very long period of time, in particular over the entire bathing season, with almost no maintenance requirements. No salt is added to the water from which active chlorine substances (CI2, HCIO, CIO) could develop. With one or more of the mentioned bicarbonate compounds or carbonate compounds, the water 10 is adjusted to a conductivity of at least 0.5 mS / cm. Once set, conductivity and hardness change, for example, by topping up or losing water. Due to the composition of the bathing water, a pH of the order of 8, depending on the amount of compound added, is in particular up to 11, an optimum range for the human skin. It is therefore not necessary to add pH regulators, it is not even necessary to check the pH during the bathing season or the bathing operation. For optimum water electrolysis function and good skin compatibility, the tap water is first softened, with a total hardness of 20 < 7 ° dH, in particular < 4 ° dH, preferably < 3 ° dH, is set.
    In the bathwater according to the invention, the alkali metal ions are derived from one or more of the compounds NaHCo3, KHCO3, LiHCC> 3, Na2Co3, K2CO3 or L12CO3, which are added. 25
    The erfmdungsgemäße bath water has a total hardness of at most 7 ° dH. In particular, its total hardness < 4 ° dH, preferably < 3 ° dH. A low overall hardness of the bath water is advantageous for a perfect and low-maintenance function of the electrolysis cell provided for electrolysis. SUBSEQUENTLY] 30 4
    The electrical conductivity of the bathwater according to the invention is mainly dependent on the content of alkali metal ions Na +, K + and Li + and should be at least 0.5 mS / cm, in particular up to 10 mS / cm, preferably up to 5 mS / cm. It is possible to add the bicarbonate compounds and / or the carbonate compounds in an amount to the bath water until the respective saturation limit is reached. A dosage at the saturation limit is recommended especially for special baths in smaller baths, which are not intended for swimming. 10 The aforementioned softening of the water can be carried out in a simple manner by reverse osmosis or by ion exchange.
    The invention further relates to the use of the bath water according to the invention for Erstbefullung in a system with a bathing or swimming pool and a treatment circuit 15 with a filter device, a circulation device and an electrolysis cell, which is installed in the bypass or in the main stream. The bath water is used to produce the oxidation or disinfectant during operation of the system by electrolysis in the electrolysis cell. Particularly suitable are electrolysis cells which optionally contain platinum, iridium, iridium / ruthenium or 20 diamond electrodes.
    Further features, advantages and details of the invention will become apparent from the following description. The invention relates to the treatment or disinfection of bathing water, in particular in swimming pools, artificially created bathing ponds, baths and the like in the private and commercial sectors. The water treatment according to the invention is based on the activation of oxygen in the bath water by electrolysis of the bath water in an electrolytic cell. At the anode 30 of the electrolysis unit formed in addition to electrolysis oxygen, peroxides and

    Alkalipercarbonate, which act as a carrier (storage) of active oxygen. In this way it is possible to achieve a depot effect for active oxygen in the entire basin.
    The bathwater itself is therefore an electrolyte which is based on tap water, in particular the water from the municipal water supply. The bath water according to the invention has a hardness < 7 ° dH (degree of German hardness), in particular < 4 ° dH and preferably < 3 ° dH, and a content of at least one of the alkali metal ions Na +, K + and Li + between 100 mg / 1 and the saturation limit, preferably between 500 mg / 1 and 5000 mg / 1. The conductivity of the bathwater has a value between 0.5 mS / cm and the conductivity value which rises when the saturation limit is reached. Water in swimming pools is adjusted in particular to a conductivity of up to 10 mS / cm, preferably of up to 5 mS / cm. A preferred value for the conductivity is 2.5 mS / cm. The content of Cf ions in the bathwater is very low, resulting only from the natural content of Cf ions in tap water used, which is usually between 1 mg / 1 and 40 mg / 1. The bath water also has due to the low hardness only a low content of Ca2 + and Mg2 + ions.
    The content of the alkali metal ions Na +, K + and Li + is achieved by the addition of one or more of the bicarbonate compounds NaHCo3, KHCO3 or LiHCC> 3 and / or 20 of one or more of the carbonate compounds NajCos, K2CO3 or L12CO3. Preferably, the addition of NaHCO 3 is optionally together with Na 2CC> 3, the ratio of these two compounds depending on which pH is to be adjusted in the bath water. A pure solution of NaHCO 3, depending on the amount of NaHCO 3 in water, gives a pH between 7.6 and 8.2, a pure solution of Na 2CC> 3 a pH 25 value of up to 11. The total hardness is adjusted before Addition of these compounds by precipitation of hardness, preferably in a known manner by reverse osmosis or ion exchange. Thus, for example, when pelvis or pool filling the tap water in a reverse osmosis system or an ion exchanger system (Wasserentkalkungsanlage) are softened.

    After filling the bath or swimming pool with softened water, one or more of the bicarbonate or carbonate compounds mentioned are or are added in such an amount until the electrical conductivity of the water reaches a specific, preselected value in the range of 0.5 mS / cm to the 5 value when reaching the saturation limit. As already mentioned, in the case of water in swimming pools, this area is preferably between 0.5 and 10 mS / cm, for example 2.5 mS / cm.
    To produce the disinfectant from the electrolyte, the bath water, by means of 10 electrolysis, the bath water is passed through an electrolytic cell. The electrolytic cell may be constructed in a manner known per se, its electrodes being in particular made of iridium, iridium / ruthenium, platinum or diamond electrodes (such as electrodes of doped diamond particles). The electrolytic cell may include one or more bipolar electrodes of the mentioned materials. The electrolysis cell is installed 15 in particular in the pump-operated circuit for water treatment in the bypass or in the main stream, at a point after the mechanical filtering in a filter device, such as a sand filter. In a bath containing about 100 m3 of water, for example, during operation of the water treatment, with the pump running, about 1200 liters of water per hour in the bypass 20 passed through the electrolysis cell.
    Alternatively, for smaller baths, hot tubs or hot tubs, the electrolytic cell can be designed as a dipping cell, for example, according to Austrian Patent No. 509286 and positioned directly in the pool. 25
    As a result of the electrolysis of the bath water, depending on the composition of the bath water, the active oxygen compounds sodium percarbonate, sodium hydrogen percarbonate, potassium percarbonate, potassium hydrogen percarbonate, lithium percarbonate, lithium bicarbonate, and hydrogen peroxide are formed so that the bath water is optimally treated. Particles that fall into the bath water are removed mechanically by the filter device. In contrast
    FOLLOW-UP 7 to biological treatment systems, it is sufficient if the treatment cycle is in operation for approximately eight hours per day. As a result of the composition of the bathwater, a pH of between about 8 and about 11 is automatically established, which is maintained. It is no longer necessary to check the pH of the pool water during the bathing season and therefore it also eliminates the need for regulative addition of pH elevation or pH lowering chemicals, as required for chlorine disinfection.
    If it is necessary to top up with fresh water, or if larger amounts of rain have entered the bath or pool, it may be advisable to check the conductivity to add a bicarbonate or carbonate compound, if needed, to restore the desired conductivity.
    A swimming or bathing water according to the invention also does not develop chlorine odor and it eliminates the accumulation of organochlorine compounds. No water change is required and steel corrosion is not expected due to the very low chloride content and absence of chlorine-based oxidizer and pH> 8 (compare Pourbaix diagram for iron). By a pH in the range of about 8 to about 11, the bathing or swimming water is also extremely friendly to the skin. Γ
