  • Should water treatment chemicals be added?
  • The addition of water treatment chemicals has always been considered as a standard operation in water and wastewater treatment. The concentration of chemicals was usually kept to the minimum necessary to achieve a good quality of potable or otherwise treated water.
  • What are water treatment chemicals?
  • 2. Water treatment chemicals – the full picture Water treatment chemicals are the solid core of water treatment processes. They became essential about a hundred years ago, after an expert panel discussion on the chlorination of potable water as a means of preventing waterborne diseases [ 9 ].
  • How are water treatment technologies changing the world?
  • Indeed, water treatment technologies are now using novel physical treatment methods. Membranes largely replaced granular filtration, and UV is paving the way towards minimization or elimination of the use of classic disinfection chemicals, such as chlorine and its derivatives.
  • What is the future of water treatment?
  • The future of water treatment is linked to the novel, physical treatment methods that were introduced to reduce the demand for water treatment chemicals in the first place. Unfortunately, at the current time, the increased performance of the new physical treatment methods depends heavily on the additional chemicals they actually require. 3.
