Is it possible to take dirty river water (or any other water for that matter) and use flocculation to turn it into clean and safe water in a short amount of time? I know that you would need a flocculant, something to disinfect the water and I've read that I need a buffer but I'm not sure about what that is, and some clay for better flocculation. For the flocculant you could use aluminium or iron sulfate For the disinfectant you could use calcium hypochlorite Not sure about what clay to use And all I know of buffers is that they are used to keep PH constant (would calcium carbonate work in this case?) Is there anything else that is needed? Also what would be the ratio for all the ingredients (say if you needed 20 litres of clean water)? I'm curious to know if this method can be used to drink seawater?
