What filters should be used for water with high levels of heavy metals?
Heavy metals in water bodies have many chemical forms, and their environmental behavior is very complex. Therefore, it is necessary to select the proper treatment method according to its chemical morphology and physical and chemical properties so as to remove it effectively from water.
What filters should be used for water with high levels of heavy metals?
chemical methods for the removal of heavy metals by chemical reactions, including chemical precipitation, oxidation-reduction, electrolysis, and enhanced coagulation.
the physical method enables the heavy metals to carry on the adsorption, the enrichment and the separation under the condition which does not change its chemical form, the common methods include the membrane separation, the adsorption method, the ion exchange resin method
At present, there are mainly physical, chemical and biological methods for the removal of heavy metals in water bodies.
