| product |
It produce a solution of strengths 0.8% and the only raw materials required are salt, water and electricity |
By-product of the chlor-alkali industry, with a concentration of 10%, containing an excess of alkali and harmful impurities |
|
| Attenuation |
Without attenuation |
Attenuation of 5% per day, and also cause excessive Chlorine in drinking water |
|
| Safety |
Safety disinfection method, environmental non-toxic. |
Dangerous articles. Risk during transport and storage and easily caused degradable when storage. Short time storage and high transport costs. |
|
| 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. |

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 cannot 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 |
