Working Principle

The Bshh-3200 System produces high-concentration sodium hypochlorite through electrochemical and chemical reactions, following these key steps:

1. Water Pretreatment: 

2. Saturated Brine Purification: 

Raw water is purified via multi-media filtration, water softening, and reverse osmosis to remove impurities, calcium, and magnesium ions. The resulting pure water is stored for subsequent use.

Purchased salt is dissolved in water to form saturated brine, which undergoes primary and secondary purification (via Doyle-type clarification tanks and ion exchange modules) to reduce calcium, magnesium, iron, and other interfering ions to acceptable levels.

3. Membrane Electrolysis:

Purified NaCl solution is fed into the membrane electrolyzer. The transformer rectifier converts alternating current (AC) to direct current (DC) to power the electrolysis process:Anode Reaction: 2Cl^- - 2e^- → Cl₂ (Chlorine gas is generated)
Cathode Reaction: 2Na⁺+ 2H₂O + 2e^- → 2NaOH + H₂ (Sodium hydroxide and hydrogen gas are generated) 
The PFSA membrane separates the anode and cathode chambers, allowing unidirectional transfer of sodium ions.

4. NaClO Synthesis: 

5. Recycle Systems: 

Chlorine gas from the anode is absorbed by a vacuum generator and transferred to a reaction chamber, where it reacts with sodium hydroxide from the cathode to form sodium hypochlorite. The reaction equation is: Cl₂ + 2NaOH → NaCl + NaClO + H₂O. A heat exchange system maintains the optimal reaction temperature to avoid sodium chlorate formation.

Anolyte, catholyte, and depleted brine are recycled through dedicated systems to maximize raw material utilization and minimize waste.

Application Scenarios

1. Heavy Industry Wastewater Treatment

2. Chemical Industry Wastewater Treatment

It is suitable for disinfection and sterilization of wastewater from heavy industries such as iron and steel, non-ferrous metals (copper, aluminum, nickel, etc.), and machinery manufacturing. These industries often produce wastewater containing high concentrations of organic pollutants, heavy metal ions (e.g., Fe²⁺, Pb²⁺, As³⁺) and pathogenic microorganisms. The high-purity sodium hypochlorite generated by the system can not only effectively kill harmful bacteria and viruses in the wastewater but also assist in the oxidation of partial organic matter and heavy metal ions, reducing the environmental risk of wastewater discharge. At the same time, the system's low raw material consumption and stable operation characteristics can adapt to the long-term, large-scale wastewater treatment needs of heavy industry enterprises.

For chemical plants producing pulp, textiles, chemical fibers, starch, and greases, the Bshh-3200 System can provide a continuous supply of high-concentration sodium hypochlorite. In addition to treating pathogenic microorganisms in chemical wastewater, sodium hypochlorite can also be used as a bleaching agent in the production process of pulp and textiles, and as an auxiliary agent for the treatment of organic pollutants in wastewater (such as chloroform precursors generated by excessive oxidation of organic matter) . The system's ability to avoid dependence on the local chemical market ensures that chemical enterprises are not affected by fluctuations in the price of commercial sodium hypochlorite, maintaining the stability of production and wastewater treatment processes.

3. Food and Beverage Industry Wastewater Treatment

4. Municipal and Environmental Sanitation Wastewater Treatment

5. Agriculture and Animal Husbandry Wastewater Treatment

Food-grade sodium hypochlorite produced by the Bshh-3200 System complies with the requirements of China National Standard "GB 19106-2013 Sodium Hypochlorite Solution" and is applicable to wastewater treatment in the food and beverage industry, including beverage factories, fruit and vegetable processing plants, and food manufacturing plants . The wastewater in this industry usually contains a large amount of organic matter (such as residual fruit and vegetable pulp, protein) and food-borne pathogens (such as Escherichia coli, Salmonella). The system's generated sodium hypochlorite can efficiently disinfect the wastewater to meet the discharge standards, and its low degradation rate (only 0.049% in 7 days) ensures the stability of the disinfection effect, avoiding secondary pollution caused by insufficient disinfection.

Against the background of urban expansion and increasing public health requirements, the system can be applied to the disinfection treatment of municipal sewage treatment plants, especially for the advanced treatment of tail water before discharge. Compared with traditional chlorine gas disinfection, it eliminates the safety risks of chlorine gas transportation and storage (such as chlorine leakage accidents that may cause casualties and evacuation of residents), and avoids the problem that chlorine gas causes excessive oxidation of organic matter in water to form carcinogens such as chloroform. It can also be used for the disinfection of domestic sewage in large residential areas, scenic spots, and other places, helping to improve the quality of the urban water environment.

In large-scale farms (such as livestock and poultry farms) and agricultural product processing bases, the system can treat wastewater containing a large number of animal feces, residual feed, and pathogenic microorganisms (such as avian influenza viruses, foot-and-mouth disease viruses). The sodium hypochlorite generated by the system has a strong disinfection and deodorization effect, which can kill harmful pathogens in the wastewater, reduce the spread of diseases in the agriculture and animal husbandry industry, and reduce the odor pollution caused by wastewater discharge. Meanwhile, the system's skid-mounted design is convenient for on-site installation in farms located in suburban or rural areas, reducing the difficulty of infrastructure construction.
