Of course, these methods only measure the sludge filtration ability and do not give any information on the dewatered

The method includes combining a first fluid comprising elastomer latex with a second fluid comprising particulate filler; causing the elastomer latex to coagulate, thereby forming masterbatch crumb; bringing the masterbatch crumb to a water content of about 1 weight percent to about 20 weight percent, thereby forming a dewatered
coagulum; removing water from the dewatered
coagulum by subjecting the dewatered
coagulum to mechanical energy, thereby causing the dewatered
coagulum to heat as a result of friction, while allowing the dewatered
coagulum to achieve a temperature of about 130[degrees]C to about 190[degrees]C, wherein water content is reduced to about 0.
