Abstract: Provided are filtration matrixes formed from adsorptive media, such as activated carbon, and polymeric binder for use in water filtration systems. A first aspect of the invention provides methods of making a filtration matrix comprising: mixing an adsorptive media with a polymeric binder to form a mixture; impulse filling a mold with the mixture; and processing the mixture to form the filtration matrix. Filtration matrixes formed from this method are also provided. Another aspect includes methods of making a filtration matrix comprising: mixing adsorptive media with a polymeric binder to form a mixture; filling a mold with the mixture; and applying heat and pressure the mixture to form the filtration matrix, wherein the step of applying pressure to the mixture comprises compressing the mixture until a desired final shape of the filtration matrix is obtained.

Abstract: Aspects of the present disclosure provide composite carbon blocks with improved capacity for the removal of contaminants such as THMs (trihalomethanes) and trace VOCs (volatile organic compounds) found in water. In one aspect, a filtration matrix comprises a polymeric binder and an adsorptive media comprising activated carbon having a bulk density of 0.54 (0.57, or even 0.60) g/cc or greater. The carbon BET surface area can be 1100 (950, or even 550) g/cc or less. The polymeric binder can be ultra high molecular weight polyethylene. Also provided are methods of making filtration matrixes.
