Abstract
UN METODO DE SEPARACION DE SELENIO HEXAVALENTE DISUELTO DEL AGUA, POR TRATAMIENTO EN UN REACTOR QUE CONTIENE BIOMASA MICROBIANA QUE CAUSA LA CONVERSION DE SELENIO HEXAVALENTE A FORMAS DE SELENIO QUE SE PUEDEN SEPARAR FACILMENTE DEL AGUA, Y CAUSA O PERMITE LA ELIMINACION DE LAS FORMAS DE SELENIO SEPARABLES DEL AGUA. EJEMPLOS DE FORMAS SEPARABLES DE SELENIO SON LOS COMPUESTOS DE SELENIO ORGANICOS VOLATILES, LOS COMPUESTOS DE SELENIO, INORGANICOS VOLATILES, SELENIO ELEMENTAL, COMPUESTOS DE SELENIO COMPLEJADOS ORGANICAMENTE ARRASTRABLES, COMPUESTOS DE SELENIO TETRAVALENTES ARRASTRABLES, Y COMPUESTOS DE SELENIO DIVALENTES ARRASTRABLES. LOS COMPUESTOS DE SELENIO VOLATILES SE PUEDEN ELIMINAR Y RECUPERAR COMO UN GAS, MIENTRAS QUE LAS FORMAS ARRASTRABLES DE SELENIO PUEDEN SER ARRASTRADAS PORPARTICULAS MAS GRANDES Y SER SEPARADAS,POR EJEMPLO POR FILTRACION, LA APLICACION DE LA INVENCION ES PARA EL TRATAMIENTO DE AGUAS.
