The purpose of screening devices is to

Explanation:
Screening devices remove large solids from the flow, acting as a physical barrier that traps debris before it can reach pumps, pipes, and downstream treatment steps. This pretreatment function prevents clogging, wear, and fouling of equipment. They don’t change chemical properties like pH, don’t remove dissolved minerals, and don’t disinfect the water. Disinfection and chemical adjustments handle those tasks, while screening focuses on physically removing objects that are too large to pass through the system.
