its filtration the heating of the 34 spent dispersion 34 can be accomplished by means well known in the art such as disposing at least one heat exchanger in fluid communication with the stream of 34 spent dispersion 34 prior to its entry into the filter assemblies 100 heating the 34 spent dispersion 34 can lower the viscosity of the 34 spent dispersion 34 depending on the carrier selected and thus provides greater filtering efficiency preferably the stream of 34 spent dispersion 34 is heated to a temperature range of between about 160 u00b0 f to about 180 u00b0 f additionally the stream of 34 spent dispersion 34 can be pressurized prior to its entry into the filtration assembly 100 the stream of 34 spent dispersion 34 can be pressurized to a range of between about 200 lbs in 2 to about 1000 lbs in 2 preferably the stream of 34 spent dispersion 34 is pressurized to a range of between about 400 lbs in 2 to about 700 lbs in 2 most preferably the stream of 34 spent dispersion 34 is pressurized to a range of between about 550 lbs in 2 to about 650 lbs in 2 the pressurization of the stream of 34 spent dispersion 34 also increases the efficiency of the separation of the 34 spent dispersion 34 into and paint solids and carrier the process can also include concentrating the 34 spent dispersion 34 prior to the filtering operation that is the 34 spent dispersion 34 can be allowed to settle or concentrate in the collection.
