Water cycle optimization for complex fertilizer manufacturing based on quality improvement of waste water treatment

Abstract

The necessary precondition of transition to reserved water circulating systems in the mineral fertilizers plants is the increase of the waste water purification degree. In this connection, in the present work the results of researches of thin purification of waste water on the base of a carbone method are discussed. As a result of study of the process various variants realization has been established, that the deepest purification degree is achieved at its realization on base of two stage scheme of the basic purification without preliminary branch of a deposit before carbonization. The practical realization of the developed method of waste water purification will ensure an opportunity of stable functioning of reserved water circulating systems in manufacture of fertilizers and will allow to prevent 'the fluoration' of others water circulating systems
