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.
