Reducing Replacement Costs of ROWPU Elements CPT Laurian G. Cuffy Replacing the filter elements of the Reverse Osmosis Water Purification Unit (ROWPU) is extremely expensive, but units can keep replacement costs at a minimum with some alternatives available today. One 600-gallons per hour ROWPU with 8 filters and one 3,000-gallons per hour ROWPU with 12 filters, for example, have a combined filter replacement cost of $15,555.75. Projected Armywide, these filter replacement costs could adversely impact unit funds for soldier training. Maximizing operational hours while minimizing operational costs for the ROWPU filter elements with proper storage, equipment tests and operator training will save money. The Army’s workhorse, the ROWPU produces potable water from a variety of raw water sources such as wells, lakes, seas, lagoons, rivers, oceans and ice holes. The ROWPU’s filters, called reverse osmosis or RO elements, are critical to desalinization and purification of water. These filters have a lifecycle of 1,000 to 2,000 operational hours. Conceivably, a ROWPU will not operate continuously or indefinitely on one set of filters. The duration of the mission will dictate down time for the ROWPU. Also, the end of deployments or training exercises and winterization of the ROWPU will result in down time. During a ROWPU’s down time, the unit must take steps to preserve the lifecycles of the RO elements with proper storage procedures. Doing so will prevent bacteria growth on the RO membranes, and such bacteria can take the filters out of operation. For proper removal and storage of RO element filters using heat-sealable plastic bags and the chemical sodium bisulfate, refer to TM 10-4610-232-12, 4-320, Change 2. Although the technical manual’s storage procedures are workable, units may consider purchasing stainless steel canisters (NSN 4610-01-467-3213). Unlike the plastic bags, the metal canisters cannot puncture and cause potential environmental problems for the storing unit. The work of RO elements begins when the ROWPU operators feed raw water through the filters at intensified pressure. The filtration process separates impurities from the raw water, whether fresh, brackish or salt water. Then the ROWPU operators add disinfectant to the filtered water to conclude the purification process before storing the water as potable. Critical to this whole process is the proper functioning of the RO elements. ROWPU operators monitor the system’s gages to monitor how well the RO elements are working. Improperly functioning filters must be cleaned or replaced. Cost-Saving Options At least two commercial businesses offer units cost-saving options for cleaning and replacing the ROWPU’s RO elements. For example, a California-based company called Argo Scientific has been rebuilding RO elements at a cost of about $100 per filter. Another option is Watec’s cleaning and testing kit (NSN 4610-01-467-3242). In addition to cleaning the RO elements, this kit allows a unit’s ROWPU personnel to assess which RO elements are not operating properly. For the 3,000-GPH ROWPU, for example, the system is not designed to distinguish which of the 12 RO elements are fouling the purification process. Therefore, after ROWPU operators attempt to clean the RO elements, the soldiers generally replace all 12 of the filters. The cleaning kit both cleans the RO elements and checks them for serviceability. This allows ROWPU operators to replace only RO elements that no longer filter water. For ROWPU operators in units that are not producing potable water during training exercises, a simulator is available to train on ROWPU operations. These devices have no shelf life and cost the unit $2,000 per ROWPU. One set will support 12 filters in a 3,000-GPH ROWPU, compared to a replacement cost of more than $11,000 per ROWPU for the 12 RO elements. These training devices simulate saltwater operations but require operators to use fresh water sources to simulate saltwater operating conditions. Conducting ROWPU training with simulators has the potential of saving units money. (Units must avoid using saltwater sources when using this training procedure. Forces Command, Army is the source for the updated technical improvements.) Properly storing the RO elements, regenerating the filters when possible and using simulators for training soldiers can reduce the related costs of ROWPU operations Armywide
