What is it about?
Due to the scarcity of water resources in Egypt, it has been resorted to reuse agricultural wastewater in irrigation operations, but due to its mixing with sewage and industrial wastewater in addition to the presence of pollution from pesticides used in agriculture, so it is necessary to treat this water before use, by using cheap and available materials in the Egyptian environment as well as environmentally safe. Sand, gravel and activated carbon filters were used with the addition of clay minerals

Why is it important?
The results showed a significant improvement in the quality of the treated water, as the active carbon improved the physochemical properties, and the bentonite (clay minerals) removed heavy metals from the water in acceptable proportions, and the sand filters reduced the turbidity of the water, and the treated water became safe for use again in irrigating crops.
Perspectives
I hope that this article will be the starting point in the development of mobile agricultural wastewater treatment units, and that the pursuit of developing these technologies is either by developing the design to suit all different forms of irrigation or by proposing other agricultural wastewater treatment materials, taking into account the economic aspect in all cases.
