German water treatment specialist, Lutz-Jesco, has released a sampling station with sensor technology that lets pool owners continuously record and measure the amount of chlorine in water. This unit is set to launch this month at Interbad 2024, the international trade fair for swimming pools, saunas and spas in Stuttgart, Germany.
It aims to allow users to proactively initiate water care measures, avoiding pungent indoor pool smells and at the same time reducing operating costs. The sensor ensures that the chemical dose is used in accordance with DIN 19643-1.
Chloramines are the problem child of many swimming pool operators. The chemical compounds are always formed when free chlorine in the water reacts with organic substances such as urea from urine and sweat after the disinfection process.
“Even at low concentrations, chloramines cause a pungent smell that has scared off many a swimmer. For people with weakened immune systems, they can even cause a health hazard,” Lutz-Jesco expert in swimming pool technology Thomas Beutel says.
“In order to reliably and accurately determine the concentration of bound chlorine in the water, we have developed a new type of sampling station which we will be presenting for the first time at Interbad 2024.”
The solution for determining the bound chlorine works as follows: Water samples from the swimming pool flow continuously through the sampling station. Integrated sensors record the various water parameters such as free chlorine, total chlorine, redox voltage and pH value. The station then calculates the amount of bound chlorine based on the difference between total chlorine and free chlorine.
This method is necessary because bound chlorine comprises a large number of different compounds with different chemical properties, which would be too time-consuming to measure individually.
