Trichloramine (TKA) - Measurement and analysis in bathing facilities
TTrichloramine is formed when nitrogenous substances (e.g. sweat and urine) react with the disinfectant in the bath water. Trichloramine is a volatile gas which, when released from the bathing water, pollutes the room air. Exposure to trichloramine in bathing facilities is mainly via inhalation.
General advice from the Public Health Agency of Sweden
In their knowledge summary (2015:16), the Swedish Work Environment Authority states that; "with regard to health aspects, the trichloramine level should be kept as low as possible". The Public Health Agency of Sweden's new general advice on swimming pools, HSLF-FS 2021:11, states a guideline value of more than 0.2 mg/m3 NCl3 in indoor air.
Measurement on the ground
EnviroProcess offers measurement and analysis of trichloramine in bathing facilities. The measurement takes place on site at one or more measuring points, the sample is then analysed at an independent laboratory that performs the analysis. A written report is provided when the results of the analysis are available. Samples can be taken directly from the air in the bathing facility, but trichloramines can also be measured in the pool water, using the so-called "Chalmers method". Sampling should be carried out at high/peak occupancy in the swimming pool.
REDUTRI - Electrochemical oxidation (EKO)
New patented solution for effective reduction of trichloramine release from bathing water. SafeWater Scandinavia AB, in co-operation with researchers at Chalmers University of Technology, has developed a patented solution for significant reduction of trichloramine emissions. It is based on electrochemical oxidation of chlorine-nitrogen compounds present in the bathing water, which are thus decomposed into chloride ions and nitrogen gas. Good results have been documented at various bathing facilities.
- REDUTRI is better than any other method at reducing trichloramine release, as documented (30-70 %).
- The equipment is specifically designed to reduce trichloramine release and has no undesirable documented side effects.
- A low voltage is used for optimal performance, which means a virtually negligible power consumption (about 20 kWh/year per cell).
Measuring is knowing - How is it done?
It all starts with data via a correctly performed and accurate measurement. We therefore offer an efficient way to measure trichloramine. The measurement takes place on site at one or more measuring points. The sample is then analysed at an independent laboratory that performs the analysis. A written report with customised recommendations for action is then provided. Samples are taken from the air at a certain distance from the surface of the water and in all pools at the swimming centre. We also offer measurement of trichloramines in the pool water using the so-called "Chalmers method".
