Study of the Applicability of the Root Wastewater Treatment Plants with the Possibility of the Water Recirculation in Terms of the Surfactant Content

Abstract

Anthropogenic activities cause the accumulation of pollutants in the aquatic environment. Conventional wastewater treatment plants do not completely remove emergent pollutants, including personal care products, in which the surfactants are an essential ingredient. The results of our study confirm the presence of the surfactants in the aquatic environment, which represents an ecological and environmental risk. It was confirmed by ecotoxicological tests (test with using Daphnia magna and Lemna minor) and the specified content of the surfactants in the samples. The content of the surfactants in personal care products is significant and their impact on the aquatic environment is not sufficiently monitored. Root wastewater treatment plants, as innovative cleaning methods, represent effective cleaning methods, which can be used as a separate object or as an object for further cleaning already cleaned water from conventional wastewater treatment plants. Purified water from these devices can be recycled and used again as utility water (according to the model presented in the article). A significant benefit from the point of view of global warming and the effect of anthropogenic activity is the saving of drinking water as a natural resource. Root wastewater treatment plants ensure the required quality of discharged water in the aquatic environment.
