EVALUATION OF ENVIRONMENTAL SUSTAINABILITY INDICATORS OF NORTHERN RUSTIMEH WASTEWATER TREATMENT PLANT IN BAGHDAD, IRAQ, USING SIMAPRO7.1 PROGRAM

Abstract

The importance of the management of wastewater treatment plants is the process of purification of wastewater from impurities, suspended materials, pollutants and organic matter to be re-usable (non-human) or to be suitable for disposal in the waterways without causing pollution. Wastewater treatment involves several physical, chemical and biological phases. Because any wastewater treatment plant (WWTP) has environmental risk and negative impact, it is necessary to assess environmental sustainability indicators and thus can diagnose their risks and find solutions to reduce their environmental and health impacts in order to preserve the essential elements of the environment (water, air and soil) and on the conservation and sustainability of the natural resources of generations. There are many software programs designed to assess environmental sustainability indicators for any sewage treatment plant. SimaPro7.1 is one of several programs which are used to count and determine the ecological (environmental) effects related to wastewater treatment technologies. In this study, SimaPro7.1 has been used to inventory test namely the analysis of inputs to the plant, such as materials used in stage of construction of the plant, incoming wastewater, consumed energy, quality of treated wastewater and quantity of sludge produced, as well as the analysis of effluents to water and emissions air and assess an effects caused by Northern Rustimeh WWTP. An outcome from Life Cycle Assessment (LCA) shows the pollutant which emitted to all environment sub-compartment such as Carbon monoxide, Lead, Dinitrogen monoxide and another pollutant which causes impacts and damages to environment by 12.4GPt to every (1m3) of sewage. The results show that generality effects were (global warming, respiratory inorganics and nonrenewable energy); also most damages were on human health, climate change and resources.
