  • What is the best chlorination method for HWT in Brazil?
  • Chlorination in Brazil In Brazil, chlorination is much more widespread in rural and isolated communities. Nationally, the most recommended chlorination practice for HWT is the use of 2.5% chlorine solution.
  • Why is a low adherence to chlorine treatment a problem in Brazil?
  • The low adherence to this treatment was mostly reported due to: i) taste and odour caused by chlorine; ii) the lack of convenience to treat water every day; and iii) the belief that the water had good quality. To increase the compliance and adequate dosage, different types of diffusion chlorinators have been used in Brazil.
  • Is free chlorine effective against protozoa?
  • Free chlorine is effective against a range of bacteria and viruses associated with contaminated drinking water but it is less effective against protozoa, especially at the concentration range acceptable for drinking water ( CDC, 2014a; Mohamed et al., 2015 ).
  • Is there a difference between chlorination practices during drinking water treatment interventions?
  • There can be a significant difference between the chlorination practices during drinking water treatment interventions for research purposes and the real-world conditions. According to Mclaughlin et al. (2009), the compliance rate is often higher in intervention studies compared to the actual situation.
