Abstract
UN PROCEDIMIENTO Y APARATO PARA EL TRATAMIENTO DE AGUAS CLOACALES PARA PROPORCIONAR RETIRADA EFICAZ DE SELENIO (ESPECIALMENTE EL SELENIO SEXAVALENTE). EL PROCEDIMIENTO Y APARATO REDUCE SELENIO DEL SELENIO SEXAVALENTE MEDIANTE TRATAMIENTO MICROBICO QUE INCLUYE UN PASO DE DESNITRIFICACION PARA OBTENER SELENIO CUATRIVALENTE Y/O SELENIO SIMPLE, SEGUIDO DE UNA SEPARACION DE SOLIDO-LIQUIDO. PUEDE AÑADIRSE UN AGENTE PARA SEPARAR EL SELENIO CUATRIVALENTE.
