Abstract
Geo-biological processes are designed to treat wastewater generated in animal feed lots when washing away feces, urine and other materials or in municipal wastewater systems. The present processes are focused on recovering a nutrient load in the wastewater for use as fertilizer and corresponding to separate mostly purified water for reuse. Alternate embodiments are algae and microbe based processes. The processes can be used individually or in various permutations.
