Automatic Large Type Sodium Hypochlorite Wastewater Treatment For Sewage Plant


Generation principle:

The revolutionary CNJS-S series sodium hypochlorite generator is a newly and for on-site product of NaClO equipment and use for all kinds of needed NaClO disinfected. The sodium chloride solution under the certain voltage effect of the cell, a series of electrochemical reaction within the cell and the resulting solution is the NaClO solution. The main process can be simplified as follows:

NaCl+H2O+DC→NaClO+H2

The electrode reaction:
anode:2Cl--2e→Cl2
cathode:2H++2e→H2
solution:2NaOH+Cl2→NaCl+NaClO+H2O


Product system:

Brine preparation part: Including water softener, dissolving tank, salt feeder, mixing
system , etc.

The advantage analysis of on-site sodium hypochlorite

Compared with traditional disinfection methods:

Water sewage treatment plant 60000 T/D, available chlorite dosing quantity 3 PPM, need 180kg everyday.

Disinfection method

On-site
Sodium hypochlorite

commercial
sodium hypochlorite

UV

Making process

It produce a solution of

strengths 0.8% and the only
raw materials required are
salt and water and electricity, so it has a

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

Generally within the ultraviolet fluorescent mercury released from plasma discharge.

attenuation

Without attenuation

Attenuation of 5% per day, and also cause excessive Chlorate in dinking water

Usually by the turbidity impact, gradually weakened life six months after the exposure time is short, there is no continuous disinfection capacity, and there may be a problem microorganisms resurrection light, preferably in the case of process water for immediate use, no secondary pipeline better raw water pollution and biological stability of the situation (generally require organic matter content of less than 10μg/L)

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

Quartz tube require regular cleaning, heavy workload, each lamp should change the water. Easy to do radiation uniformly over the entire processing space, shaded area exposure

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.

None

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

Early investment in small, high maintenance costs, large daily operating costs.

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

Regular cleaning, the effect can not be controlled and also need regular to test water quality.

  • ECONOMIC ANALYSIS
  • On-site Sodium Hypochlorite

Unit raw material consumption:
DC Power consumption : 4.5kW·h/Kg Cl2
Salt consumption :3.5 Kg / Kg Cl2
Daily energy consumption:
Daily power consumption :180 x 4.5 = 810kW·h
Daily salt consumption :180 x 3.5 = 630 Kg
The raw material price :
The average power price :0.6 RMB / kW.h
Edible salt price :0.8 RMB /kg
Daily operation cost :
electricity :810 × 0.6 = 486 RMB
Salt :630 × 0.8 =504 RMB
Daily operation cost:486 +504 =990 RMB / D

UV operation cost Tube :1500 RMB / piece,Need: 8*14*2 = 224 pieces,The service life is about one year.Daily cost::1500*224/365=920 RMB / D
electricity:35.84 kw / set,One day:2*35.84*24*0.7=1204
Daily operation cost:920+1204 =2124 RMB / D

  • 10%commercial sodium hypochlorite cost:

10% commercial sodium hypochlorite to the factory price is 130 RMB / T, and covert into active chlorine is 1300 RMB / T, and the daily plant need available chlorine is 180 kg
The daily cost is :13*180=2340RMB / d

  • The cost compared On-site sodium hypochlorite with UV and commercial sodium hypochlorite

Available chlorine production

180 kg/d

UV running cost

2124 RMB / D

Commercial sodium hypochlorite

2340 RMB / D

Sodium hypochlorite generator running costs

990 RMB / D

The on-site sodium hypochlorite
system daily saving

1134 RMB / D and 1350 RMB / D

The on-site sodium hypochlorite system annual saving

1134*365=41.3 thousands RMB /y
1350*365=49.3 thousands RMB /y


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.
