Abstract

LA TORTA DE FILTRACION (47) ES ATRAVESADA AUN DENTRO DEL FILTRO DE PLACAS (10) POR UN FLUIDO, P.J.UN GAS, A UNA TEMPERATURA DE 60 HASTA 300 GRADOS C, QUE FAVORECE LA EXTRACCION DEL LIQUIDO DE LA TORTA DE FILTRACION. LA PROPORCION DE LIQUIDO CONTENIDA EN LA TORTA DE FILTRACION, DE APROXIMADAMENTE DEL 30 HASTA AL 50 POR CIENTO, SE PUEDE EXTRAER CASI COMPLETAMENTE Y UTILIZARSE DE NUEVO. LA TORTA DE FILTRACION TRATADA ESTA COMPLETAMENTE LIBRE DE LIQUIDO AL RETIRARLA DEL FILTRO DE PLACAS Y, POR TANTO, SE PUEDE EVACUAR MAS FACIL Y ECONOMICAMENTE QUE HASTA AHORA. TAMBIEN ES POSIBLE LA REUTILIZACION COMO MATERIAL AUXILIAR FILTRANTE PORQUE LAS PARTICULAS PRACTICAMENTE NO SE ADHIEREN, SINO QUE ESTAN PRACTICAMENTE DE ESTADO ORIGINAL. POR ELLO, LAS PARTICULAS ESTAN DE NUEVO EN SITUACION DE FORMAR UNA TORTA DE FILTRACION MUY POROSA. AL MENOS UNA PARTE DEL MATERIAL DEPURADO PUEDE REUTILIZARSE, DE MANERA QUE SE REDUCE CONSIDERABLEMENTE LA CANTIDAD DEL MATERIAL RESIDUAL A DEPONER.
