Abstract

UNA SUSPENSION ACUOSA DE MATERIAL COAGULABLE SE COAGULA AÑADIENDO UN COAGULANTE POLIMERICO A LA SUSPENSION Y POSTERIORMENTE SEPARANDO EL MATERIAL COAGULADO RESULTANTE DE LA SUSPENSION. EL MATERIAL COAGULABLE PUEDE ESTAR PRESENTE EN LA SUSPENSION ACUOSA COMO SUSPENSION DE SOLIDOS SUSPENDIDOS O COMO SOLIDOS DISPERSADOS COLOIDALMENTE. LA SUSPENSION PUEDE SER DE RESTOS DE CARBON U OTRA SUSPENSION ACUOSA GENERALMENTE MINERAL. EL MATERIAL POLIMERICO DEBE DE SER UN MATERIAL POLIMERICO ALTAMENTE IONICO Y DE BAJO PESO MOLECULAR. EL MATERIAL SE AÑADE A LA SUSPENSION ACUOSA MIENTRAS SE ENCUENTRA EN FORMA DE PARTICULAS POLIMERICAS QUE TENGAN UN TAMAÑO DE ALREDEDOR 30(MU)M Y QUE SE DISOLVERA EN LA SUSPENSION Y COAGULARA EL MATERIAL COAGULABLE. GENERALMENTE SE AÑADE UN FLOCULANTE CONTRAIONICO, DE ALTO PESO MOLECULAR PARA FLOCULAR A CONTINUACION EL MATERIAL COAGULADO.
