Abstract:
A method of mixing organic carbon with the final effluent for water treatment systems and applying the mixture to manmade stratified sand filters or natural soils to induce proper conditions for high removal of total nitrogen in the final effluent. In one embodiment, water having a concentration less than about 30 mg/l of Total Nitrogen (TN) and a BODconcentration of less than about 30 mg/l is mixed with a sufficient amount of dissolved carbon to cause a reduction of the nitrogen pollution in the water, and the water and dissolved carbon are percolated through a fixed bed.A method of mixing organic carbon with any water having dissolved TN and applying the mixture to manmade stratified sand filters or natural soils to induce proper conditions for high removal of total nitrogen in the applied water.A method of mixing organic carbon with any water having dissolved TN and applying the mixture to manmade stratified sand filters and applying the water to the soils and inducing in situ denitrification caused by the discharge of water having the proper Carbon to Nitrogen ratio for soil bacterial metabolism and by the discharge of long chained insoluble particular carbon, which degrades in the soils and soil water and provides carbon for denitrification.
