Ensuring clean drinking water and managing wastewater are vital for public health and the environment. These complex processes, from raw water intake to treated water distribution and wastewater discharge, rely heavily on precise fluid control at every step. Valves regulate intake, flow through treatment stages (sedimentation, filtration, disinfection), chemical dosing, and distribution pressure. Similarly, in wastewater treatment, valves manage flow in collection systems, within treatment plants (sedimentation, biological treatment), sludge transfer, and effluent discharge. Selecting the right valves, resistant to abrasives and chemicals, is crucial for efficient, safe, and cost-effective operation, preventing contamination and conserving water. The critical processes within water and wastewater treatment demand robust and reliable flow control. This involves ball valves for isolation and chemical dosing, butterfly valves for efficient flow regulation in larger pipelines, gate valves for dependable isolation, check valves to prevent backflow, and plastic valves for chemical resistance. Strainers remove debris, protecting equipment. Crucially, safety valves prevent overpressure in pressurized systems.
