Zusammenfassung:	Disclosed is a filter element from removing contaminants from water comprised of first filter media particles having a first particle size and second media particles having a second particle size and methods for making such a filter element. The first media particles are adhered to surfaces of the second media particles. A binder connects the second media particles with one another so that interstitial spaces are formed between second media particles. A portion of the smaller first filter media particles are positioned within the interstitial spaces. According to one embodiment of the disclosure water flows through the filter element at a flux greater than about 1.5 ml/min/cm2 has a pressure drop less than 20 psi.
