The Baltic Sea Region faces increasing pressure on water resources and ecosystems due to human activity, with nutrient rich treated wastewater discharges being a main cause of eutrophication. Combining algae-based nutrient removal with reclaimed wastewater reuse provides a sustainable solution to reduce pollution while allowing algal biomass recovery for further applications. Therefore, the aim of the study was to evaluate possibilities to use algae cultivation as a tool for nutrient removal from treated wastewate...

As a result of increasing concentrations of total nitrogen and total phosphorus, surface water chemical pollution and eutrophication is a problem of raising concern worldwide. Chemical quality of surface water gives an impression about different geochemical, geological, hydrological and biological processes, as well as intensity of anthropogenic load in river catchment area. The total length of Svete River is 123 kilometres, of which 75 kilometres are in the territory of Latvia. Main part of river?s drainage basin...
