Environmental assessment of the operation of wastewater treatment plants

Abstract

The essence of the application of the life cycle assessment study is to avoid increasing the quality of individual products and services at the expense of environmental degradation. Life cycle assessment is regarded as a universal method that is useful for any organization, regardless of the nature and scope of business. The effectiveness of wastewater treatment can determine and assesses potential risks associated with operation of wastewater treatment plant to the environment using appropriate methodology. The implementation of the method requires formulizing processes, using exact methods, allowing identifying the environmental impacts on the environment. Life cycle assessment belongs in industrialized and environmentally conscious states among ordinary tool of environmental management.The scientific part is the introduction of general standards for specific wastewater treatment plant. The emphasis is given on correct understanding of the problem, regarding the definition of objectives, functional unit, system boundaries, and evaluation indicators. Based on the monitoring and measurement of pollutants in samples of wastewater, the data is processed by the competent life cycle assessment software.

Analysis and balance of phosphorous removal from wastewater at urban wastewater treatment plant

“…1.8 g P/day. If 80% P is removed from the sewage treatment plant and if sludge is used on the agricultural land, recycling of 3.6 tones P/day or 1300 t/year might be possible [9].…”
