NaClO Solution Sodium Hypochlorite Generator Advantage Analysis 3 kg / h
Product introduction:
Generation principle :CNJS - M series NaClO generator is a new type of NaClO solution for field production equipment , suitable for all kinds of needs NaClO disinfected venues . Its working principle is: the sodium chloride solution under the certain cell voltage function, in a series of electrochemical reaction occurs in the cell , the resulting NaClO solution , including the generation of NaClO through chemical equation can be expressed as follows :
NaCl+H2O+DC→NaClO+H2 ↑
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.
