    Abstract Today, they use sand for construction and civil projects. To use sand, they first process it after extraction and wash it, which causes the consumption of a lot of water. It comes out as waste water. To reduce the consumption of underground water and to prevent great damage to the environment, this waste water must be treated, and there are methods for this.Method such as traditional methods in which a pond is dug and the effluent is released into it so that it does not come into contact with the environment. There are also industrial methods that can be done using devices such as dryers and thickeners. He treated the sewage.Treatment of this waste water plays a role in maintaining the environment and even reducing costs from an economic point of view. Waste water treatment also increases the quality of materials because it causes useful materials such as wind sand or clay to remain in the composition of the sand and causes high The adhesion of sand is lost in mortar or concrete.
