摘要

Improved procedure for the purification of nitrates or lime in contaminated water and equipment used in said procedure. It comprises a first stage of ion exchange by the passage of a flow of contaminated water counter-current inside the beds of nitrate resins or lime located inside tanks, thus producing the process of denitrification or decalcification of water contaminated and obtaining water suitable for mouth consumption; a second stage of regeneration of said resin beds once their exchange capacity is exhausted based on the passage of contaminated water to current through the resin beds and simultaneously the passage of a regenerating solution by said beds to counter-current; and a third stage of utilization of the solution resulting from the second stage for its use as liquid fertilizer or as irrigation water enriched in nutrients. When reusing the regeneration eluates the performance of the procedure and the equipment is very high and the losses are minimal. (Machine-translation by Google Translate, not legally binding)
