A method for the separation of ammonium nitrate hold strength condensate - waste water into two reusable liquid proportions

摘要

A method for the separation of ammonium nitrate hold strength condensate - waste water from an evaporator unit in two reusable components is characterized in that the condensate - waste water into a concentrate solution and the permeate in a first reverse osmosis - stage is separated, that the permeate of the first reverse osmosis - stage of a second reverse osmosis - stage is supplied and in this reverse osmosis - step in as process water in reusable permeate and is separated in the concentrate solution, the said first reverse osmosis - stage - condensate supplied waste water is added, and in that the concentrate solution of the first reverse osmosis - stage of a third reverse osmosis - stage is fed and permeate, the said first reverse osmosis - stage - condensate supplied waste water is added, and in the concentrate solution is separated, which is returned to the evaporator unit.
