In the Electrolyser, the current is passed through the anode and cathode in the salt solution. which is a good conductor of electricity, thus electrolyzing the sodium chloride solution.
This results in chlorine (Cl2) gas being produced at the anode, while sodium hydroxide (NaOH) and hydrogen (H2) gas is produced at the cathode.
The reactions that take place in the electrolytic cell is:
2NaCl+2H2O=2NaOH+Cl2+H2
The chlorine further reacts with the hydroxide to form sodium hypochlorite (NaOCl). This reaction can be simplified in the following manner:
Cl2+2NaOH=NaCl+NaClO+H2O
The solution generated has a pH value between 8 and 8.5, and a maximum equivalent chlorine concentration of less than 8 g/l. It has a very long shelf life which makes it suitable for storage.
After dosing the solution into the water flow, no pH value correction is necessary, as is often required in sodium hypochlorite produced by the membrane method. The sodium hypochlorite solution reacts in a balance reaction, resulting in hypochlorous acid:
NaClO+H2O=NaOH+HClO
To produce 1kg equivalent of chlorine using an on-site Sodium Hypochlorite generator, 3.2-3.5 kg of salt and 4-kilowatt hours of electricity is required. The final solution consists of approximately 0.8% (8 grams/liter) sodium hypochlorite.
Specification:
Simple: Only water, salt, and electricity is required
Non-Toxic: Common salt which is the main substance is non-toxic and easy to store. Electro chlorinator provides the power of Chlorine without the danger of storing or handling hazardous materials.
Low Cost: only water, common salt, and electricity is needed for electrolysis. The total operating cost of an Electrochlorinator is less than the conventional Chlorination methods.
Easy to dose to get a standard concentration: Sodium hypochlorite generated on-site does not degrade like commercial sodium hypochlorite. Therefore, the dosage need not be modified on a daily basis based on the strength of the hypo solution.
Approved disinfection method complying with the drinking water regulations – an alternative with fewer safety requirements to chlorine-gas-based systems.
Long service life, as compared with the membrane cell electrolysis
On-site generation of sodium hypochlorite allows the operator to produce the only which is needed and when it is needed.
Safe for the Environment: As compared to 12.5% sodium hypochlorite, the use of salt and water reduces carbon emission to 1/3rd. The hypo solution of less than 1% concentration produced by our system is benign and considered non-hazardous. This translates to reduced safety training and improved worker safety.
Sodium Hypochlorite generated on-site with the help of synthetic brine or seawater is very efficient in protecting the equipment from the growth of micro-organic fouling and control of algae and crustaceans. Compact Electrochlorinators manufactured by Shandong Better company are ideal for the disinfection of water during disasters like earthquakes, Floods, or Epidemics. Electrochlorinators are designed for rural and village “point-of-use” disinfection of drinking water.
