The complete dosing unit is a brand-new concept of chemical water treatment dosing equipment, which has been widely applied in water treatment fields such as power, chemical, and municipal engineering both at home and abroad. It integrates all equipment and components such as metering pumps, solution tanks, control systems, and pipeline valves onto a single base platform to achieve the overall combination of solution preparation and metering dosing functions. It features a compact structure, small floor space, and ease of transportation and installation. "Feihong" has, through years of dedicated efforts in water treatment technology and experience, developed a new type of combined dosing unit with advanced reliability, flexible configuration, and the ability to meet users' arbitrary selection requirements based on different water quality treatment requirements and dosing characteristics, by drawing on and absorbing advanced dosing technologies from both domestic and international sources, and using high standards to provide water treatment system solutions as the product design concept.
