Working principle: 5NaClO2+ 4HCl produce 5NaCl+2H2O+4ClO2 Constitution: It mainly consists of six subsystems with the following functions: chemical storage, dosing and reaction, mixing and absorption, automatic control and protection. Features: (1) Advanced technology: the technology to produce chlorine dioxide with sodium chlorite and hydrochloric acid is the first choice for all famous chlorine dioxide generator manufacturers in the world. (2)High yield: average yield coefficient of chlorine dioxide is up to 95% and no residual or harmful by-products are produced during the process. (3)Highly automated With unique high-automated control system, the generating capacity of the unit could vary automatically according to the amount of water input or residual chlorine in water output after being processed. Generating capacity could also be controlled by a combined loop according to flow rate and residual chlorine amount. Thus, the concentration of effective chlorine in water could be maintained constantly. (4)Quality components and advanced technology ensure the high quality, reliable performance and long life of the unit. (5)Safety and reliable: Alarm system sounds and automatically stops the unit when chemicals or water quantity is under predetermined value. Specifications Four series including manual/power operated and automatic/ full automated Over 40 specifications with effective chlorine generating capacities ranging form 30g/h to 10kg/h Applications: Widely used in municipal water supply, food processing, hygiene and sanitation, domestic or industrial water use as well as disinfection of public places. Particularly adapted to small and medium-sized water works, secondary water supply for high buildings, swimming pools and circulating cooling water for the purpose of disinfection, sterilizing, deodorizing and removal of iron as well as manganese.
