The Diploma in Chlorination at QLS Level 4 Chlorination will teach learners about chlorination and the history of chlorination. It refers to the process of adding chlorine or hypochlorite in order to achieve certain objectives. The most widely used form of chlorination is water chlorination and refers to the process of adding chlorine or hypochlorite to water in order to kill certain bacteria or microbes present. The main goal of water chlorination is to prevent the spread of waterborne disease such as cholera, dysentery and typhoid. Although chlorination cannot inactive all microbes, it is highly effective in killing many viruses and bacteria present in water.

Chlorination is one of the most widely used methods to disinfect water along with coagulation, sedimentation and filtration. This method was identified over a century ago and is still in use today.

The Diploma in Chlorination at QLS Level 4 will provide in-depth knowledge of chlorination and an overall understanding of chlorine, halogens and iodine.
