ANALYSIS SALT WATER CHLORINATOR CL2 AND CHEMICALS CHLORINATOR
USING CHLORINE IN FLOODING WATER
Disinfecting water and killing algae with chlorine is an effective method that is widely used today. In water environment, 20°C exists in 2 forms of HOCl and OCl –
There are two methods of sterilization:
This is a new technology that uses electrode rods to make Cl 2 from sodium chloride
Electrolytic process Electrolytic NaCl
2NaCl + 2H2O -> 2NaOH + H 2 + Cl 2
Cl 2 + H 2 -> HOCl + HCl
HOCl is a strong oxidant, the main disinfectant.
Common sources are Calcium Hypochlorite [Ca (OCl) 2 ] and Sodium Hypochlorite (NaOCl) produced industrially. When these compounds dissolve in water produce OCl – ( Oxidizing Compounds)

USE OF READY ANTISEPTIC |
Advantages |
+ Do not create unpleasant smell or cause irritation. + Effective disinfection because HOCl compound is stronger than OCL – 100 times. + Cost savings during use. + Easy to buy kitchen salt. + Make safety for swimmers.
|
Cheap investment, easy to operate. + Quick water treatment, increasing the amount of chemicals into the lake easily. + OCl can effectively sterilize in high pH environment.
|
Defect |
High initial investment cost + The electrolysis process will increase the pH (pH balance with dilute HCl). Inefficient in high pH environment. + Water is salty. |
+ Causes irritation, and allergy to sensitive skin, causing fear to the swimmer. + Cost of labor for daily operation. + OCl – not effectively sterilized by HOCl. + Easy to evaporate if it’s sunny and outdoor pool. + Supply of imported chemicals. + low cost in the process of use.
