Have you considered mechanical coagulation and flocculation?

For muddy river water, the process my company typically uses is fine and ultrafine bubble aeration which causes coagulation and flocculation due to the properties of the ultrafine bubbles. As well as oxidation to strip out iron, manganese, ammonia and other dissolved organics. This then goes through a static mixer which further provides further flocculation. By this stage the floc is large enough to be filtered out by a media filter. We typically use an Activated Filter Media which provides reliable filtration down to 1 micron with 99% efficiency. Biofilm does not develop on the media bed and hence chlorine demand is significantly reduced, I have seen up to 80% in some cases. This is a solution being used to provide clean drinking water for over 2,000,000 people in developing countries across Asia as of this year.

Our company seeks to provide water treatment solutions that either eliminate or significantly reduce the use of toxic chemicals. If you are interested in learning more about this process of water treatment, please email me at andrew@waterandoilsolutions.com.au
