Zusammenfassung:Disclosed is a filter media for removing contaminants such as organic acids from water. The filter media comprises porous particles. The particles have a total pore volume greater than about 0.4 cc/g. The pore volume is primarily or substantially comprised of epipores, that is, pores that are larger than about 5 nm. The filter media may also include a non-porous filter material and a binder. The filter media may be formed into a filter element, with the binder joining particles of the filter media together into a solid body. The percentage of the total pore volume provided by epipores is greater than about 40%. The filter reduces an initial concentration of an organic acid by greater than 80% at a flux greater than 0.76 ml/min/cm2.
