4-3 Chlorination system description. The chlorination system generates a strong solution of sodium hypochlorite (commonly
called chlorine) for treating water produced by the Reverse Osmosis Water Purification Units (ROWPU's). Adding this solution to the
water makes it safe for human consumption. A metering pump adds this solution, upon demand, to water processed by the ROWPU
system just before the water enters the four drinking water storage tanks. The chlorination system's major components are shown in
Figure 4-1 for Barge 1 and in Figure 4-2 and for Barges 2 and 3. Major components are listed in Table 4-1. The system generates
and maintains a 5000 to 6000 parts per million (ppm) solution of chlorine and then meters this solution into product water from the
ROWPU I system to obtain a chlorine concentration of 5 to 7 ppm in the drinking water.
