When iron forms a colloid in water, what methods can be used to remove it?
When iron forms a colloid in water, coagulants can be used to disrupt this colloid structure, causing it to aggregate into larger particles, which can then be removed through clarification and filtration processes. Common coagulants include: aluminum sulfate, polyaluminum chloride, ferric chloride, ferrous sulfate, magnesium carbonate, polyferric sulfate, ferrous chloride, etc.
