Probably the easiest is to use centrifugal filtration with an ultrafiltration membrane, as found in products such as the Millipore Centricon and Microcon systems. Dialysis against a solution high in PEG (or solid PEG) also will remove water but not the enzyme. Often, storage in 50% glycerol at -20C is a good approach for longer term.
