Subject:
Spray Pond Additive for Antimicrobial Control
Reference:
LGS Industrial Waste NPDES Permit # PA00051926
Dear Ms. Fields:
Limerick Generating Station is requesting the addition of GE Betz Spectrus NX1 103, an EPA approved broad spectrum antimicrobial agent, to the list of approved chemicals. It would replace GE Betz Spectrus CT 1300, a material used for periodic biocide treatment of Spray Pond cooled equipment. Testing has shown that the CT1 300 material, which has been used for over ten years, is no longer an effective biocide unless applied at a concentration of >75 ppm.
NX1 103 would be applied at 30 ppm during a 75-minute biocide treatment twice per week.
Each treatment, consisting of 11.25 pounds of product, would combine with 375,000 gallons of the spray pond inventory of 29,000,000 gallons, or 1.29% of the Spray Pond total volume.
NX1 103 would also be applied, on average, 1.5 times per week at 30 ppm, for a 75-minute biocide treatment of the RHR Service Water system. Each treatment, consisting of 22.5 pounds of product, would combine the biocide with 750,000 gallons of the Spray Pond inventory, or 2.57% of the Spray Pond total volume. This would yield an addition rate of about 45 pounds of NX1 103 to the spray pond per week. Total usage rates for NX1 103 applications would be as follows maximum daily - 120 lbs/day, based on both ESW and all four RHR systems requiring treatment on the same day; and average monthly -20 lbs/day, based on weekly ESW treatments and twice per month treatment of all RHR heat exchangers.
The treatments return to the spray pond and mix with the water inventory of 29 million gallons.
The average overflow from the spray pond is approximately 20 gallons per minute, which combines with average Cooling tower blowdown of 6000 gpm.
After implementing NX1 103 usage, two applications per year of CT1 300 would still be required to treat for Asiatic clams in the ESW/RHRSW systems. Each application lasts for 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />, and typically injects 25 pounds of CT1 300 into the Spray Pond.
Should you have any questions regarding this information, please contact Bob Alejnikov at 61 0-718-2513. Thank you for your cooperation in this matter.

Spectrusw NX1103 Microbiological Control Agent Broad spectrum antimicrobial Proprietary blend minimizes microbial resistance FDA Approved (CFR 176.180 and 176.300)
USDA Approved (G5, G-7)
Approved for sale in California DESCRIPTION AND USE Spectrusu NX1103 is EPA approved for control of bacteria, algae, and fungi in a variety of industrial water-based systems. Specrus NX1 103 consists of a proprietary blend of 10% dodecylguanidine hydrochloride (DGH) and 5% methylene bis (thio-cyanate) [MBT].
Spectrus NXI 103 is approved for use in open recircu-lating cooling systems, heat exchange systems and evaporative condensers.
Control of microbiological populations in industrial water systems is essential to prevent biofouling. In cooling systems, biofouling of heat exchange equip-ment and tower fill reduces heat transfer efficiency and can force unscheduled shutdowns and extended turnarounds, leading to lost production. Equipment can also be damaged as a result of microbiologically influenced corrosion (MIC) associated with biofouling.
Consequently, biofouling must be prevented in order for operating units to avoid such events and achieve profitability goals.
Compared to single active biocide products (see Chart), the combination of surface active agent (DGH) and metabolic inhibitor (MBT) in Spectrus NX1103 work together to provide faster microbial control at lower dosages. The blend of actives in Spectrus NXI 103 also limits development of resistant microbial populations and reduces the need to alter-nate products to maintain effectiveness.
In addition to cooling systems, Spectrus NXI103 can be used to control microbes in influent water systems, air washers, pasteurizers, and water-based scrub-bers. See the Spectrus NX1 103 product label for a complete listing of approved end uses.
TREATMENT AND FEEDING REQUIREMENTS Correct treatment levels and frequency of Spectrus NXII03 addition depend on many factors. These indude, but are not limited to, system cleanliness, types of microbes, nutrient concentrations, tempera-ture, p1-, retention time, and other system operating characteristics. Consult the product label for general dosage guidelines. Microbiological monitoring is rec-ommended to evaluate product requirements.
Consult your GE Betz representative for technical advice on your specific application.
In all cases, this product must be applied in accor-dance with use instructions on the Spectrus NXI103 label.
Feed point - Apply Spectrus NXI 103 to a point in the system where turbulence and flow patterns assure good mixing with the water being treated.
