Description:

The course deals with the problem of treating small wastewater streams, particularly in rural areas where conventional treatment is not feasible. Detailed information will be given on concepts for low technology wastewater treatment with the response to the environmental problems caused by improper water and wastewater management. Selected types of on-site treatment methods, e.g. infiltration systems, sand filters and constructed wetlands will be presented with the regards to the local and legal requirements. Treatment systems suitability in different planning situations will be presented and discussed. Attention will be given to the role of rural areas in wastewater treatment. Two aspects of productive wastewater treatment: protection of water resources against pollution and intensification of biomass production under water efficiency and limited amount of mineral fertilisers, will be pointed out. Study tour covering the example of productive wastewater treatment system (Ner river valley) and selected types of on-site treatment is predicted. The understanding of pollutant removal processes will be a base for predicting longevity of treatment system efficiency. Possibility of wastewater nutrient recycling as an important goal of sustainability will be pointed out. Low technology solutions for nutrient recycling and recovery, e.g. sorption through reactive filters or wastewater use for irrigation and biomass production will be presented and discussed. As the result, the course participants will learn how to plan, design and construct low technology wastewater treatment plants.
