SECTION III. TECHNICAL PRINCIPLES OF OPERATION
1-9.
WATER PROCESSING AND CHEMICALS. The ROWPU removes suspended solids (called turbidity),
chemicals, and solids held in solution (called dissolved solids), found in most fresh water and seawater sources, to a level
fit for human consumption. This is done by filtering with the aid of the reverse osmosis process, and then additional
purification using selected chemicals. Refer to figure 1-15 to follow the process described below.
