Method of Recovering Potassium from Waste Waters for Use in Purification of Waste Water, including the Waste Water from which the potassium is Recycled, while retaining the Potassium in forms suitable for use as a Nutrient in Growing Microbes, Plants and Algae

摘要

A method for recovering and/or utilizing potassium from waste waters for a plurality of applications. As algae and plants are able to survive and flourish in environments with high salt concentrations, waste waters containing potassium can be applied as fertilizers to the growth of microbes, algae and plants. The microbes, plants, and algae are able to absorb the necessary nutrients, such as nitrogen and potassium, from the waste waters. After depletion of the potassium content from the waste water, that waste water can then be treated to separate other contaminants. In another aspect of the present invention, the potassium content may be first separated from the waste water to be applied for growth of microbes, plants, and algae and again used for regeneration of cation resins in specific potassium forms. The remaining contaminants that are separated through treatment of the waste water can be utilized for different productions.
