Automatic sodium hypochlorite generation for water treatment

1,Principle of sodium hypochlorite disinfection

Sodium hypochlorite liquid is put into water and hydrolyzed instantaneously to form hypochlorite and hypochlorite radical. Because hypochlorite is a small neutral molecule, it has no charge and can quickly spread to the surface of negatively charged bacteria and viruses, and penetrate into bacteria through the cell wall of bacteria. Hypochlorite is further decomposed to form new ecological oxygen [o], which is highly oxidizing and destroys the protein and other enzyme systems on bacteria and viruses; So as to kill pathogenic microorganisms.

NaClO+H2OHClO+NaOH

HClO=HCl+[O]

Sodium hypochlorite is mainly used as a disinfectant in water treatment to kill some pathogenic microorganisms and bacteria in the water body, reduce the chromaticity of the water body, remove odor, remove iron and manganese, etc.

2,

Why choose on-site sodium hypochlorite preparation technology

------ Safe,economical and practical

1),security:

Safety is the concept we have always adhered to, mainly in the following aspects

Safe raw materials: refined salt, electricity and water

Safe process: there is no potential risk of chlorine leakage, and the system adopts 11 safety guarantees

Safe products:

Sodium hypochlorite with a concentration lower than 1% is a safe concentration

Sodium hypochlorite with a concentration lower than 1% will not decay during storage

By products are lower than commercial sodium hypochlorite

2),Economy

A,Economic analysis

Purchase cost of liquid chlorine: 5 RMB/ kg Cl2

Purchase cost of commodity sodium hypochlorite: 9.8 RMB / kg Cl2

Operation cost of chlorine dioxide (chemical method): 8.9 RMB / kg Cl2

(high purity method) operation cost: 14 RMB/ kg Cl2

3,Practicality

Raw materials: simple and easy to get, only need salt transportation

Product: the product is stable and easy to store

Effect: the disinfection effect is good, and the by-products meet the standard
