Abstract

EN UN METODO DE DESHIDRATACION DE RESIDUOS DE LODOS VERTIDOS POR UNA FACTORIA TAL COMO UNA FACTORIA DE PASTA DE PAPEL, LOS RESIDUOS DE LODOS SON PRIMERO DESHIDRATADO POR UN DISPOSITIVO DE DESHIDRATACION PRELIMINAR TAL COMO UN PREESPESANTE DE UN TIPO DE PANTALLA GIRATORIA, UN LODO DESCARGADO A PARTIR DEL DISPOSITIVO DE DESHIDRATACION PRELIMINAR ES ENTONCES SUMINISTRADO A UN DISPOSITIVO DE DESHIDRATACION PRINCIPAL COMO UNA PRENSA ROSCADA. LOS LIQUIDO RESIDUALES DESCARGADOS A PARTIR DE LOS DISPOSITIVOS DE DESHIDRATACION PRELIMINAR Y PRINCIPAL ES ENVIADO A UN TANQUE DE REACCION DE AGLUTINACION JUNTO CON UN REACTIVO DE AGLUTINACION MACROMOLECUALR Y SUSTANCIAS AGLUTINADAS EN EL TANQUE DE AGLUTINACION DONDE SON TRATADAS POR UN DISPOSITIVO DE DESHIDRATACION PRINCIPAL DISTINTO DE DICHO DISPOSITIVO DE DESHIDRATACION PRINCIPAL. UNA CANTIDAD NECESARIA DEL REACTIVO DE AGLUTINACION MACROMOLECULAR A ENVIAR AL TANQUE DE REACCION DE AGLUTINACION PUEDE SER REDUCIDA, MIENTRAS LA EFICACIA DE DESHIDRATACION NOSE DETERIORA.
