The van-type body mounted water purification unit, Met-Pro Model 1500-2600, consists of water purifying equipment installed inside an insulated and heated van body, mounted on a M45 2½ ton truck. The water purifying equipment consists primarily of the water treatment section, where raw water is mixed and treated with chemicals; the filter section, where chemically treated raw water has impurities removed; and necessary valves, piping, and controls to direct production of potable and palatable drinking water from fresh water at the rate of 1500 gallons per hour. Supporting equipment required for the unit includes a 10KW engine-driven generator set, mounted in a standard 1½ ton cargo trailer. The water purification set is constructed for movement over rough terrain as well as smooth surfaced roads. Areas traveled are limited only by the capability of the truck upon which the water purification unit is mounted.
