Q291.13C Please show the calculations leading to the estimates of the maximum usage of. sulfuric acid for cooling water pH control and to the estimates of the average'and maximum amounts of organophosphonates used (Table 3.6-2).
The method of calculation given in response to question 291.10, if used, would lead tc. a number that was different from the estimated maximum amount of sulfuric acid (31,000lb/ day) given in Table 3.6-2.
The difference between the average sulfuric acid use for pH control (25,200 lb/ day) and the maximum use (31,000 lb/ day), as listed in Table 3.c-2, appears to be small when compared with the difference between the average river alkalinity
.(160 mg/L) and maximum river alkalinity (319 mg/L) listed in Table 3.6-1.
Q291.14C The numbers for the maximum use of Na0H, H 504 and Nacl listed in 2
Table 3.6-2 are not consistent with the maximum amounts of sodium, sulfate.and chloride added to the plant discharge as listed in Table
-3.6-5, Revision 1.
Please explain the discrepancy or provide updated table: that are consistent.
