Distillation Systems use a process of heating water to the boiling point and then collecting the water vapor as it condenses, leaving many of the contaminants behind. Distillation Systems have a very high effectiveness in removing protozoa (for example, Cryptosporidium, Giardia);
How does water flow?
Water flows from freshwater sources into water treatment plants where the water goes through four stages before being put into storage for distribution. These are the four stages: 1 Coagulation and Flocculation- Chemicals are added to the water. These chemicals have a positive charge which draws dirt and unwanted particles into larger flocs. 2 Sedimentation- When this occurs, the floc slowly falls to the bottom of the treatment tank. 3 Filtration- The water at the top will then pass through filters to remove dirt, rocks, sand, and other particles such as bacteria and parasites. 4 Disinfection- Once the water passes through the filtration process, a disinfectant is added to the water to kill any other bacteria and germs that are still present.
