In the Jieyang area water disinfection industry, sodium chlorate hydrochloric acid mixed configuration of chlorine dioxide is called the chemical method of chlorine dioxide, the characteristics are as follows:
Chemical method of chlorine dioxide: that is, sodium chlorate and hydrochloric acid reaction to generate chlorine dioxide, the method of the early stage of the more cost-effective, but there are the following shortcomings:
Purchase of approval before the need to use. Sodium chlorate and hydrochloric acid as a hazardous chemical, before use need to go to the government public security department for the record approval, the process is complicated.
Inconvenience in purchasing and transportation. Sodium chlorate and hydrochloric acid are hazardous chemicals that are strictly regulated by government departments and are not easy to purchase or transport.
Inconvenient storage after procurement. Sodium chlorate and hydrochloric acid have to be stored in two separate warehouses, and if they are not properly managed and explode, it will cause a major safety accident and incalculable losses to the organization.
High demand for preparation personnel. Preparation process equipment will produce irritating gases, preparation personnel need to strictly follow the preparation process, personnel working in the process need to wear high-quality gas masks.
High demand for preparation equipment. Chemical chlorine dioxide preparation generally use high purity chlorine dioxide generator, if the equipment is not up to standard, in the preparation process mixed with the production of other chemicals, easy to cause equipment explosion.
The preparation process is strict. Both reactions require a certain reaction time, and water disinfection process on the water temperature, Ph value in water, etc. have very strict requirements, once a slight error, will cause waste of sodium chlorate and hydrochloric acid, the reaction is not sufficient, it is easier to produce THMs and other "three" by-products, will cause secondary pollution of drinking water sources, leaving a hidden safety hazard.
Dioxide is the most common type of chemical in the world.
Chlorine dioxide finished preparation: chlorine dioxide disinfection method is more convenient and cost-effective.
Convenient storage. No need to record; procurement in the direct delivery through logistics; procurement only a warehouse storage, placed in a cool place can be.
Simple usage. Chlorine dioxide finished preparations add activator configured into mother liquor, can be used directly, activation and use of high efficiency, there is no harmful by-products.
Cost-effective. The cost of chlorine dioxide can basically be equal to the price of chemical chlorine dioxide, if the unit used before the chlorine dioxide generator, chlorine dioxide preparation of AB agent can replace sodium chlorate and hydrochloric acid to produce chlorine dioxide.
Low power consumption. Because the finished preparation is pure, the power required to generate chlorine dioxide is 3-5 times lower than the electrolysis method and chemical method.
