NaClO Solution Automatic Sodium Hypochlorite Generator 3 kg / h
Product introduction:
Main reaction process: NaCL+ H2O = NaCLO + H2↑
Electrolysis of brine type sodium hypochlorite generator is an electro chemical reaction process, the only raw material are salt and water, no other additional ingredients. The design of generator system has the character of energy saving, cost saving, high reliability, long service life, simple operation etc...
The electrode reaction:
anode:2Cl--2e→Cl2
cathode:2H++2e→H2
solution:2NaOH+Cl2→NaCl+NaClO+H2O
Technical parameters:

Compared with commercial sodium hypochlorite disinfection methods
Disinfection method | On-site | Commercial | |
Making process | It produce a solution of strengths 0.8% and the only PH of 9 and making it less likely to cause scaling | By-product of the chlor-alkali industry, the concentration of 10%, containing excess alkali and harmful impurities | |
Attenuation | Without attenuation | Attenuation of 5% per day, and also cause excessive Chlorate in dinking water | |
Safety | Safety disinfection method, environmental non-toxic, liquid dosage | Dangerous articles. Risk during transport and storage and easily caused degradable when storage. Short time storage and high transport costs. Liquid dosing | |
Disinfection by-products | Due to weak in chlorine oxidation ability, three material are less, and combined additive, ammonia, potassium permanganate, less by-products | The raw material is Industrial salt, which contain harmful impurities in drinking water and it is bad for health. | |
Economic analysis | The investment is a little higher in the early time, but the operation cost is low, and after three or four years it can pay your investment money back | Equipment cost is low, but the high cost of running, and the running costs can not be controlled | |
Dosing Accuracy | Dosing liquid low concentration, can accurately control the amount of chlorine | High concentration, difficult to precisely control the amount of chlorine, dosing hole easily plug fouling |
ECONOMIC ANALYSIS:
If Water sewage treatment plant 20000 T/D, need 3kg per hour
On-site Sodium Hypochlorite
Unit raw material consumption:
DC Power consumption : 4.5kW·h/Kg Cl2
Salt consumption : 3.5Kg/Kg Cl2
Daily energy consumption:
Daily operation cost :
Power charge :288× 0.11=31.68usd
Salt fee : 252 × 0.14 =32.76usd
Water fee : 9 × 0.33 =2.97usd
Total fee : 31.68+32.76+2.97=67.41usd
10%commercial sodium hypochlorite cost :
10% commercial sodium hypochlorite to the factory price is
200usd/T, and covert into active chlorine is 200usd/T, and the
daily plant need available chlorine is 72 kg
The daily cost 0.072x 2000= 144usd
on site sodium hypochlorite daily cost saving:144-67.41=77usd
investment cost analysis
on site sodium hypochlorite generator equipment cost
Equipment investment:66666.70usd(Including dosing system)
commercial sodium hypochlorite generator
investment: 10000.00usd
cost: onsite sodium hypochlorite generator cost more than commercial sodium hypochlorite
66666.70-10000.00=56666.70usd
final cost accounting every year
operation fee:
onsite sodium hypochlorite generator
saving:77*365=28105.00usd
invest fee:
onsite sodium hypochlorite generator invest more than commercial
sodium hypochlorite generator:66666.70-10000.00=56666.70usd
on site sodium hypochlorite generator in cost saving(every
yaer) :56666.70-28150.00=28516.70usd
Equivalent to the sodium hypochlorite generator and goods nearly
years to recover all investments The costs and benefits of sewage
water disinfection by sodium hypochlorite depend on-site specific
factors such as power costs, availability of brine water, safety
,and ease of use. Disinfection using hypochlorite is often the
least expensive and most appropriate option.
