Generation and Discharge of Wastewater

Описание

Netherlands) Non-point sources include diffuse emissions from: a) road, rail and water transport, b) corrosion processes, c) run-off and drainage from agricultural soils, d) atmospheric deposition (excluding deposition on marine waters), e) urban run-off to sewers systems. Direct discharges from non-point sources: sum of direct discharges from diffuse sources and transfers like drainage and run-off from soils and direct atmospheric deposition at fresh surface waters (only N, Cu and Zn). Total discharges to the sea include atmospheric deposition at marine surface water. In most cases atmospheric deposition is the larger part of the total load to marine waters
Sweden) Industrial wastewater, total discharged only includes industrial wastewater treatment plants with a permit in the national register for environmental reports and industries with own treatment and release to water. Excluded are industrial wastewater treatment plants that transfer water to urban wastewater treatment plants
