A sodium hypochlorite generator is a device that produces sodium hypochlorite solution by using an electrolytic process. The generator typically consists of an electrolytic cell containing a cathode and an anode, a brine tank, a dilution tank, and a control system.
The process starts by adding salt (NaCl) to the brine tank, which is then dissolved in water to form a saline solution. The saline solution is then fed into the electrolytic cell, where an electric current is applied. This causes the saltwater to split into its constituent ions, with chlorine gas being produced at the anode and hydrogen gas at the cathode. The chlorine gas then reacts with the saltwater to produce sodium hypochlorite, which is collected in the dilution tank. The strength of the sodium hypochlorite solution produced can be adjusted by controlling the amount of salt added to the brine tank and the electric current applied.
Sodium hypochlorite generators are widely used in industries such as water treatment, food and beverage processing, and chemical manufacturing for their ability to produce a consistent supply of high-quality sodium hypochlorite solution. They are also preferred over traditional methods of producing sodium hypochlorite, such as using chlorine gas, due to their increased safety and reduced environmental impact.

Titanium anodes are commonly used in the production of electrolytic sodium hypochlorite due to their excellent corrosion resistance and long lifespan in harsh chemical environments.
During electrolysis, a direct current is passed through a solution of saltwater, which causes chlorine gas to be produced at the anode (positive electrode) and hydrogen gas to be produced at the cathode (negative electrode). The chlorine gas then reacts with the saltwater to form sodium hypochlorite, which is the active ingredient in bleach.
Titanium anodes are preferred over other materials because they do not react with the corrosive chlorine gas, which can cause rapid degradation and failure of other types of anodes. Additionally, titanium has a high resistance to corrosion, which prolongs the lifespan of the anodes and reduces maintenance costs.
Overall, the use of titanium anodes in the production of electrolytic sodium hypochlorite provides a reliable and efficient method for the manufacture of bleach, which is widely used in a variety of industries for cleaning and disinfection purposes.
