Do you have green and/or cloudy pool water?
Do you have green and/or cloudy pool water? You could have an algae growth, a common problem for many pool owners. Algae is more likely to grow in sunlight, warm temperatures, low chlorine levels, and at high phosphate levels.
ph Value
As we have seen pH measurement and control is essential in any pool or spa to maintain the value within the desired range. For heavily used pools, the pH value should be measured continuously and adjusted automatically, for other pools it is sufficient to measure the pH value regularly and adjust it if necessary.
Water maintenance, but how?
In order to guarantee the hygienic condition of the water under all circumstances, pool users have a wide range of options for water treatment.
Aguas de baño
Son aguas naturales accesibles al público (también llamadas aguas superficiales).Como espacios naturales sensibles, durante la estación de baño las autoridades sanitarias comprueban periódicamente la calidad del agua aproximadamente cada quince días.Para la realización de dichas comprobaciones, las autoridades nacionales se basan en la Directiva "2006/7/CE del Parlamento Europeo y del Senado del 15 de febrero de 2006* sobre la calidad de las aguas de baño y su explotación y para la derogación de la Directiva 76/160/CEE.
Estanques de baño y baño
Este término se emplea para las instalaciones de baño al aire libre con preparación biológica del agua, que están colocadas y aisladas. Es decir, se trata de ecosistemas artificiales. Su diseño se caracteriza por una experiencia de baño alternativa conforme a la filosofía de "vuelta a la naturaleza".No obstante, incluso en estas instalaciones es necesario una preparación del agua en parte costosa, aunque también libre de sustancias químicas.
Myths of water treatment
Basic requirements for healthy bathing and swimming are state-of-the-art water treatment. Both in the interest of health and in order to maintain the value of a facility, water treatment should be performed according to the motto "as much as necessary and as little as possible".
Standards for bathing water quality
Since 1976, Austria has had a Bäderhygienegesetzt (BHyg G, Bathing Hygiene Act), which is the basis for providing perfect water quality in all public swimming pools. This makes Austria one of the few countries in the world to regulate hygiene in this area by law. Efforts of this kind have also been made in Germany, but despite several attempts, no political consensus for a legal regulation has been found to date. Although there is the Infections-Schutzgesetz (IfSG, Infection Protection Act) with relatively general wording and a recommendation of the Bundesumweltamt (UBA, Federal Environment Agency), concrete framework conditions are only defined in a technical guideline of the Deutsche Industrie Norm - DIN (German Industry Standard) 19 643. Technical progress is now developing continuously, naturally also in process engineering, i.e. water treatment. This process must be taken into account within the framework of the generally recognised rules of technology. This is done by means of a cyclical inventory of the defined framework conditions and, where necessary or appropriate, supplementing and/or new processes, for example ultrafiltration in the DIN.
Balanced Water (Langelier Index)
When a water is in balance, it is said to be neither corrosive nor scale-forming. In other words, it will not deposit a layer of calcium scale neither will it dissolve an existing layer of scale.
