Description
This process represents the infrastructure construction as well as the demolition and decommissioning of a Chinese small-sized conventional treatment water treatment plant. It is assumed that all building materials and equipment are processed and installed at the water treatment plant. At this stage, the materials consumed include cement, timber, steel reinforcement, sand, gravel, steel pipes and fittings, etc., and the energy consumption mainly comprises the diesel and electricity used for construction and installation. For the demolition, recovery and disposal stage of the materials, it is assumed that metal materials and timber have a recovery rate of 90%, while other materials are treated by landfill. The data are mainly sourced from publicly available guidelines of industry associations.
Activity Description
The system boundary involves raw material preparation, on-site construction and installation, and decommissioning and dismantling phases, excluding the operation and maintenance phase.
Process Description
The water plant is mainly constructed of raw materials such as cement, wood, steel bars, gravel, steel pipes and related accessories. Its main function is to produce tap water and ensure the safety of urban water supply. Compared with conventional tap water treatment plants, advanced water treatment plants further integrate advanced technologies such as ozone oxidation, activated carbon adsorption, and membrane treatment on the basis of traditional processes. Therefore, the materials and energy consumption required during its construction are relatively higher, but it also significantly improves the stability and cleanliness of the effluent water quality, making it an indispensable and important component of the modern urban water supply system.
