Wastewater Treatment and Reuse

Abstract Managing water resources is important with the increasing population, especially in arid and semi-arid regions. It is necessary to treat wastewater and greywater to saving more water amount and increase agriculture density. The current study forecasts the amounts of wastewater and greywater for Ramadi city during the next years (2020-2040). Also, the study proposes the possibility of reusing these amounts as a renewable water resource. These liquid wastes consist of 99.9% water and only 0.1% of solids. The study proposes using the treated wastewater to plant a green belt around the city to reduce the impact of dust storms and use the greywater in irrigating vegetables and fruits. The study was used water evaluation and planning (WEAP) to evaluating water amounts and reused wastewater in the current and future years. The results were indicated the domestic water returns for the current year to Euphrates River is 63 million m 3 /year, with 11.7 million m 3 /year of greywater, which covers about 22% of Ramadi irrigation requirements. The future domestic water would increase by about 24% to reach 78.4 million m 3 /year at 2030 and 95.5 million m 3 /year at 2040, while the greywater rising to 21 million m 3 /year in 2030, and 34.3 million m 3 /year in 2040.
