Electrochlorination
Electrochlorination is the process of using salt, water and electricity to produce a low strength, low pH Sodium Hypochlorite solution directly on site.
When it comes to disinfecting water safely, chlorine is the most commonly used chemical. It is a powerful bactericide and also leaves a residual disinfectant, protecting users further along the supply chain.
The use of chlorine in the form of gas is common, as is commercial hypochlorite solution.
There is however another way: electrochlorination. This method is often used by water companies, but there is no reason it cannot also be done on a smaller scale.
An advantage of electrochlorination is that it can be produced using no other ingredients other than common salt, electricity and water. This negates the need to store chemicals and eliminates the potential dangers of chlorine gas.
