Reverse Osmosis Water Purification Unit (ROWPU)

Potable water is acritical element in the operational functioning of the Seabees. The 600 GPH Reverse Osmosis Water Purification Unit (ROWPU) purifies water by reducing the dissolved and suspended solids in water. The unit processes raw water, brackish water, and seawater into potable water. Additionally, the ROWPU can treat water contaminated with CBR agents. Two views of the 600 GPH ROWPU can be seen in figure 2-28.
