Subject:
Water Treatment Additive For Building Chiller Chemical Cleaning
Reference:
LGS Industrial Waste NPDES Permit # PA00051926
Dear Ms. Fields:
Limerick Generating Station is requesting the addition of Kleen AC9500, a dry mineral scale deposit removal agent, to the list of approved chemicals (Attachment 1). Kleen AC9500 would be utilized to remove scale that has accumulated on the administrative building chiller/cooling system (cooling tower fill and chiller heat exchanger tubes). Approximately 100-150 pounds of this product would be manually metered into 300 to 500 gallon capacity cooling system, resulting in a 3.5% solution. The number of cleaning applications will be determined by an effectiveness review conducted at the end of each cycle..
Ultimately, after product exhaustion, the chiller cooling tower will be drained and thoroughly flushed with fresh water. The normal system drain path is to the Holding Pond, which discharges through Outfall 201, and finally to the cooling tower blowdown header to Outfall 001 (Schuylkill River).
The above application rate for a three-cycle evolution would result in a concentration of 126 ppm in the Holding Pond,-based on an overflow-level-volume of 430,000gallons. -
Please advise us of the acceptability of this proposed process for chiller chemical cleaning. If you have any questions on this matter, please feel free to contact Mr. Bob Alejnikov of my staff at 610-718-2513.
