Development of an Experimental System for Grey-Water Treatment for Landscape Irrigation Purposes

Abstract:

Integrated water management aims to promote water supply from conventional resources and wastewater reuse to address issues such as water scarcity. The positive input from collecting and reusing water for household purposes has not often seen assessments of the impact of climatic change, water resource availability, and water deprivation in various regions. If the water resource comes from a clean water resource and was first used to wash or bathe, it is commonly referred to as greywater. GW is an abundant resource generated throughout people's daily lives. GW can be used for domestic cleaning, flushing toilets, washing vehicles, washing kitchen gardens, washing clothes, and washing before rinsing. This research study aims to develop an experimental system for GW treatment with the optimum cost and reuse it in landscape facilities. The main result showed achieving a suitable design for GW, which improves the water's characteristics and quality so that it is suitable for use in landscaping agriculture, at a total cost of 15.6 $ to effluent discharge water amount of 1.75 m³/h. This study showed that the presented experimental study, which uses a conventional treatment process built with existing systems, can achieve satisfactory results of GW treatment. The turbidity was reduced with an effectiveness rate of 96% and a filtration efficiency of 96.5% for TSS, particularly in filtration by a mixture of screen filter and gravel filter.
