ITEM 291.13C 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 to a number that was different from the estimated maximum amount of sulfuric acid (31,000 lb/ 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 3.6-2, 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.
Response (1)
The average amount of sulfuric acid used for cooling water pH control was calculated as described in the response to question 291.10 (see Reference 2), using an average make-up water flow rate of 31,120 gpm (2 Units) and average alkalinity of 160 mg CACO / liter (to be 3
reduced to 100 mg/L)
The maximum daily usage of H SO4 was based on the 2
maximum daily flow rate of 38,300 gpm (2 Units) and the s a m,e, average, alkalinity figure.
The maximum
/ liter represents a alkalinity figure of 319 mg CACO 3 single sample collected during a limited study.
More comprehensive river data, albeit from further downstream, shows the river alkalinity has not been seen as high as 319 and that the alkalinity level variance is less than the 319 would indicate; therefore, the use of the same (160) alkalinity value to calculate the H SO4 consumptions at average and 2
maximum flows was considered to be reasonable.
(2)
The estimates for the average and maximum amounts of organophosphonates used are based on the flow rates given in (1), above, and a dosage of 5.0 mg/L (vendor's recommendation).
291.13C
IT.'M 291.14C The numbers for the maximum use of NaOH, H SO and Nacl 2
4 listed in 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 tables that are consistent.
Response
The apparent differences, aside from round-off adjustments, between the maximum amounts of sodium, sulfate, and chloride added to the plant discharge (Table 3.6-5, Rev. 1) and the maximum use of NaOH, H #04, and Nacl (Table 3.6-2) are the amounts of those species recovered from the ion exchange resins upon regeneration.
The recovered amounts are estimated to be:
Sodium 600 lb/ day Sulfate -
816 lb/ day Chloride - 160 lb/ day These constituents are removed from the water being treated and are returned to the discharge line as part of the ion exchange regeneration wastes.
