Abstract

EN Surface-active compounds currently detected in natural waters pose a threat to the environment. Their presence negatively affects self-cleaning processes by foaming water, resulting in oxygen deficiency and eutrophication of water reservoirs. Getting into the human body with the consumed water, they can cause disease. Apart from adsorption, membrane filtration, and filtration through biologically active beds, the methods of removing surface-active compounds from treated water can also include the process of artificial infiltration. Infiltration is a process of pretreatment of captured surface water, using the forced flow of intaken surface water through the ground. The adsorption, filtration, and biodegradation processes occurring in the soil change the water quality characteristics from the surface to groundwater. In the infiltration process, organic, and biogenic admixtures, as well as color, are removed from the water and microbiological parameters are reduced. The paper presents the results of research on the artificial infiltration process in terms of removing non-ionic and anionic surfactants from the water taken. The study of the content of non-ionic surfactants was carried out using the iodobismutane method for the determination of oxyethylates with the final measurement of absorbance of bismuth-thiourea. A simplified method for the determination of anionic surfactants using methylene blue was used to measure the concentration of anionic surfactants. The tests were carried out on a field research installation, consisting of three piezometers drilled on the way of water flow from the infiltration pond to the well-receiving infiltration water. Water intake from subsequent piezometers allows the assessment of the effects of admixture removal as a function of the length of the infiltration path and the time of retention in the ground. A decrease in the concentration of test substances was observed during the migration of water from the infiltration pond to the collecting well.
