DDT is manufactured by the condensation of chlorobenzene with chloral at 30°C in presence of oleum, which is a highly exothermic reaction
Chloral is obtained by the chlorination of ethyl alcohol

Slow sand filters can remove colour completely
Activated carbon can be used for taste & odour control without subsequent filtration
Application of activated carbon reduces the temporary hardness of water
Normally, the turbidity is removed by adding a coagulant prior to sedimentation
