PLC system design for management and control of river water treatment system

Sand filters are one of the types of filters that are used to purify water, especially river water which are not suitable for public use but in the end, it depends on the specifications of the water to be treated. This requires the design of treatment systems with specific commensurate with the nature of the work in terms of the work environment, such as large factories that emit various vapors and gases such as large oil refineries as well as the natural factors of high temperatures up to 50 degrees Celsius. In the subject of this study, a model was presented for a sand filtration system used to purify the waters of the Tigris River with certain specifications and turn it into water suitable for public use and very close to one of the largest oil refineries. The material specifications for the system were appropriately selected. The subject of the study focuses on the communication, control, and management of this system using the (PLCs) logic controller, the study dealt with choosing the best types of components and devices for designing PLC control systems according to cost, work environment and technical specifications.
