SOUTH COUNTY R.O. PLANT H2S DEGASIFIER <br />MODIFICATION <br />The Board reviewed a Memorandum of July 15, 1997: <br />DATE: <br />JULY 15, 1997 <br />TO: <br />JAMES E. CHANDLER <br />COUNTY ADMINISTRATOR <br />FROM: <br />JAMES W. DAVIS, P.E. <br />rlt_/ <br />INTERIM DIRECTOR OF UTILITY SERVICES <br />PREPARED <br />WILLIAM F. McCAIN, .E. <br />AND STAFFED <br />CAPITAL PROJECTS NEER <br />BY: <br />DEPARTMENT OF L SERVICES <br />SUBJECT: <br />SOUTH COUNTY R.O. PLANT H2S DEGASIFIER <br />MODIFICATION <br />unrur_unrnm <br />As a result of increased flow in recent years at the South County <br />R.O. facility, the plant has developed problems with plugging of <br />the product water degasifiers (H2S removal equipment). The cost <br />of cleaning the packing in these units results in a labor cost <br />alone of $30,000.00+ per year. As a result of staff's <br />investigations, it has been determined that the plugging of the <br />packinc is due to a build-up of sulfide precipitate. To <br />eliminate this build-up, we can modify the pH of the water prior <br />to entering the degasifier, and the build-up will not occur. <br />ANALYSIS <br />For details of staff's analysis, please see the attached <br />engineering report. The annual costs associated with this part of <br />the treatment process are currently $118,0.45.00 versus the modified <br />process cost of $99,547.00 for an annual operational cost savings <br />f <br />Sig, '98.00. The total rcposed pro-lect cost is $7,700.00, whic^ <br />would easily be recovered in the first year alone. All <br />AUGUST 5. 1997 <br />
