The daily output of the drinking water treatment industry ranges from a few thousand tons to tens of millions of tons, and it is constantly transported to thousands of households in cities every day. Such a large cluster of public health services is a key livelihood project with a scale of thousands/tens of thousands. For any drinking water treatment enterprise that uses chlorine dioxide disinfectant in a centralized manner, a core technology equipment that cannot be separated is the chlorine dioxide generator, which is the CPU (core processor) of the water treatment and disinfection process.

With the promulgation of policies related to municipal water supply, the standards of the water treatment industry are constantly being improved. The promulgation of GB 28931-2024 "Hygienic Requirements for Chlorine Dioxide Disinfectant Generators" once again rewrites the new technical requirements and safety specifications for chlorine dioxide generators, which also puts forward stricter requirements for the drinking water industry to follow up on technological optimization and equipment configuration.

Despite the numerous brands on the market, how to conduct scientific procurement and rational selection is an experience and ability that every purchasing party of drinking water enterprises needs to possess. This article is based on market industry information and technical reports, and provides professional answers and tips for purchasing chlorine dioxide generators for enterprise purchasers.

Q1: How to choose between chemical chlorine dioxide generator and electrolytic generator?

Generators are usually classified into chemical and electrolytic functional categories, and the overall selection requirements are generally based on a comprehensive evaluation of five dimensions: processing scale, raw material supply conditions, operating costs, safety regulations, and by-product control.

Chemical generator: It is usually a solution made by reacting two raw materials in a certain ratio to produce chlorine dioxide. Due to its single device's ability to process several kilograms of solution per hour (with a raw material conversion rate of up to 75% -85%), it has a unique advantage in terms of chlorination reaction efficiency. This type is generally applicable to large and medium-sized water plants, hospital wastewater, and industrial circulating water sites.

Electrolysis generator: mainly uses salt and water to participate in electrolysis reaction, generating chlorine dioxide synergistic disinfectant. The generation of effective chlorine dioxide components may only account for 10% -30% of the actual amount (usually in the hundreds of grams per hour), with the majority being chlorine gas (a byproduct), which cannot be used and causes significant losses. Suitable for use in small and medium-sized projects or environments with relatively limited raw material storage.

Product selection recommendation:

Based on the introduction of the principle and advantages of the generator mentioned above, it is recommended that enterprise purchasers prefer to choose chemical generators for overall selection. Long term operation and maintenance of water plants require stable disinfection effects as a prerequisite, and disinfection efficiency is a more decisive condition.

Among numerous manufacturers of chlorine dioxide generators, Xiuba has nearly 40 years of experience in chlorine dioxide product research and development, and has a series of mature product matrices and technological innovation research and development reports in the field of chemical generators. It can stably output in terms of purity and safety. The XB series chemical method generator integrates multifunctional components (including feeding system, reaction system, control system, etc.) with its small body to achieve intelligent control and scientific management automation conditions. Buyers can customize and adjust according to the actual water quality characteristics and treatment needs at any time.

Q2: When evaluating a chlorine dioxide generator manufacturer, besides price, what other aspects should be focused on?

A qualified equipment purchaser should first establish a long-term operation and maintenance cost selection concept, comprehensively evaluate from five dimensions, and help you select the ideal type.

1. Enterprise qualification and compliance certification - Firstly, it is necessary to verify whether the business scope of the enterprise complies with the hygiene license approval for water related products and the hygiene license qualification for disinfection product production enterprises. Secondly, enterprises need to undergo market supervision and assessment to comply with ISO9001 quality management system, ISO14001 environmental management system and other series of certifications. In short, companies with more relevant evaluation standards and certificates are more legitimate.

2. Material and process level of core components - The quality of equipment core accessories determines the service life and corrosion resistance of the entire machine. The main core components include reactors, feeding systems, and safety devices, which should be constructed with titanium, UPVC, or composite materials as much as possible. Long term use can ensure stable working conditions.

3. Authentic and verifiable customer cases and performance - verified through online information. You can refer to relevant brand sales cases and product service cases in some purchasing channels to evaluate the advantages and disadvantages of actual usage. Evaluate compliance with standards based on data provided by others and their compliance status.

4. Technical Service System and Response Mechanism - Detailed consultation with merchants regarding pre-sales, in sales, and after-sales series selection support, installation, debugging, and fault maintenance. Can a 400 hotline be provided for technical service tracking and answering questions.

5. Process adaptability analysis capability - In the selection process, the generator manufacturer will provide a series of operations such as water quality testing, dosing simulation calculation, and time optimization plan. Only with certain service support can the purchase be more reassuring.

Q3: What are the main trends of the new chlorine dioxide generator?

The key to selection is to choose "new". In the future, intelligent management of water systems will become increasingly common, requiring personnel to have a more forward-looking perspective in considering technological trends

1. Intelligent control system - supports online residual chlorine monitoring, chlorine dioxide flow regulation, PID automatic dosing and other functions, as well as digital technologies such as remote monitoring and real-time data recording and backup. In terms of achievable automation technologies, it is recommended to select as many successful and "intelligent control" devices as possible. If the water treatment project is complex, high-end models that support access to factory level DCS systems or IoT platforms can also be selected, but the quotation is higher.

2. Modular and compact design - modular structure can be selected for equipment installation, which is easy to install, expandable, and has low maintenance costs; Another option is to use a factory assembled modular design model, which supports immediate on-site use without any installation waiting period.

3. Material and process upgrades - The reactor material should consider its ability to withstand high temperatures and corrosion. At present, the market generally uses composite materials, fluoroplastics, and titanium alloys as upgraded materials for high-quality models. This type of material will to some extent affect the accuracy of heating and temperature control. The better the material, the higher the efficiency of raw material conversion

4. Energy efficiency and raw material consumption optimization - the comparison reference of generator energy efficiency ratio is also one of the key data. Under the same production capacity conditions, products with less residual liquid production and in line with green and low-carbon standards should be selected.

5. Enhanced system integration capability - In addition to basic functions, products should also consider collaborative effects. Can it be more convenient to form collaborative treatment with pre-treatment systems, disinfection contact tanks, and dechlorination devices, which will be more beneficial for engineering personnel to carry out systematic management.
