The Baltimore Aircoil Company cooling tower “Operation and Maintenance Manual” and related documents can be found in Appendix D antibiotic resistance health care generic noroxin 400mg amex. Any part or equipment used in the cooling tower will comply with the manufacturer’s original design and performance specifications and any part or equipment used in the cooling tower system will comply with the New York City Construction Codes antibiotics via iv buy noroxin 400 mg with amex. As applicable antibiotic joint penetration best purchase for noroxin, replacement materials will be corrosion-resistant and effectively prevent the penetration of sunlight virus animation generic noroxin 400mg otc. A pre-startup cleaning is conducted for the seasonal systems and a shutdown cleaning is conducted at the end of the season. Cleanings require a complete system shutdown and will sometimes be completed in the evening or weekends. Areas where scale, debris and biofilm are likely to accumulate are paid special attention as well as water contact areas such as the basin, sump, fill, spray nozzles and fittings, drift eliminators, and air intake louvres are properly accessed or removed to facilitate cleaning. Power washing is also performed on the cooling tower to rid it of any debris as well as to clean fill sections that are present and cannot be removed. Protective equipment worn during cleaning includes googles, gloves, and coveralls. Drift eliminators are maintained, installed and inspected to ensure good working order and proper function. Visual inspections will be used to verify that they are not physically damaged or contaminated with scale or algae. All repairs will be in compliance with manufacturer’s recommendation in order to keep drift loss below the maximum allowable amount. Cleaning and disinfection will be done no later than 15 days before the first seasonal use of such tower. Start-Up for Drained Systems To be performed by a Certified and Licensed Water Treatment Contractor: Completely drain the cooling tower to protect it from offline contamination. While operating the condensing water pump(s) and prior to operating the cooling tower fans, execute one of the two alternative biocidal treatment programs* described below: 1) Treat with the biocide that had been used prior to shut down. Maintain the maximum recommended biocide residual (for the specific biocide) for a sufficient period of time (residual and time will vary with the biocide) to bring the system under good biological control. The chlorine residual must be held at 4 to 5 mg/L (ppm) for six hours, measurable with standard commercial water test kits. Start-Up for Undrained (Stagnant) Systems (If Applicable) To be performed by a Certified and Licensed Water Treatment Contractor: Remove accessible solid debris from the cooling tower sump and from any remote storage tank(s) that may be used. Do not circulate stagnant bulk cooling water over cooling tower fill or operate cooling tower fans during pretreatment. Otherwise add approved biocide directly to the bulk water source and mix with either manual or by side stream flow methods. Take care to prevent the creation of aerosol spray from the stagnant cooling water from any point in the cooling water system. When biocide residual is maintained at a 4 to 5 mg/L (ppm) level for at least six hours, the cooling tower fans may be operated. Note: All systems are required to be drained at the end of the Cooling Season as per Department of Education Requirements. Notice will include a statement that the cooling tower has been drained and sanitized. Shutdown, Startup and Idling Procedure Summary Seasonal Shutdown When the system is to be shut down for a period of more than three days, the entire system (cooling tower, system piping, heat exchangers, etc. Seasonal Startup Before cooling tower system startup, a cooling tower(s) that has been shut-down or idle for more than three days will be cleaned and disinfected. If seasonal startup a mechanical contractor will be onsite to make sure the tower is in operable condition. Idling A cooling tower(s) that has been shut-down or idle for more than three days will be cleaned and disinfected. The evaluation must describe the optimum level of chemicals to achieve the desired result in a manner which can be used as a system performance measure. Only biocide products registered with the New York State Department of Environmental Conservation may be used in disinfection. Provided that chemical treatment is demonstrated as adequate to control Legionella in the maintenance and management plan, non-chemical water treatment devices may also be installed as a part of the cooling tower system. Corrective Actions Run the system a few hours every day and adjust biocide levels 4. The shock treatment consists of sodium hyperchlorites that are circulated for 24 hours. As applicable, risk management procedures to mitigate the potential conditions listed in the below table should be undertaken, with additional sampling, measurement, and general observation to be implemented at high risk locations within the cooling tower system as identified by the risk management assessment conducted. Critical Risks and Hazards Risk Management Assessment and Management Dead legs or stagnant water in the recirculation Low Risk – Circulating pumps are used to provide system continuous water circulation Title 24, Chapter §8-03 (c)(1) Operating configurations and conditions that may Low Risk – Building checks are performed daily including occur after periods of extended inactivity lasting weekends where circulating pumps are turned on. System is offline and throughout the year making regular, periodic drained during the off season offline cleaning and disinfection difficult Title 24, Chapter §8-03 (c)(3) Any components that may add additional risk High Risk – Strainers and filters are found in the cooling factors for organic material buildup and microbial tower and are cleaned during preseason startup and growth such as strainers and out-of-use filters postseason shut down as well as if a full disinfection is Title 24, Chapter §8-03 (c)(4) required. Sources of elevated organic contamination, Low Risk – No such sources can contaminate the system. Title 24, Chapter §8-03 (c)(7) 5-20 Critical Risks and Hazards Risk Management Assessment and Management System components adversely affecting water Low Risk – No such components exist. All components are quality management procedures working as designed Title 24, Chapter §8-03 (c)(8) Other risk or limiting factors or constraints in the Low Risk – No other risk/limiting factors exist. The system is in operation with water circulating in the system for at least one hour prior to water quality measurements or collection of samples. Daily water quality parameters are measured by the Custodial Engineers, Building Managers, or Fireman from the cooling tower basin water. If any parameters are out of range and persist for an extended period of time without explanation, the Metro Group is contacted for help with resolving the problem. These samples are collected on Mondays each week from the tower basin and interpreted according to Table 2 of Chapter 8, while the cooling tower system is operating. When biocide applications are intermittent, indicators will be taken after the biocide application has had time to mix uniformly throughout the cooling tower system and reflect normal cooling tower operating conditions. Bacteriological Indicator Sampling Summary Responsible Party for the Custodial Engineer, Building Manager, and/or Fireman Indicator Collection Indicator Collection All samples will be taken from the basin of the Cooling Tower Location(s) Indicator Sample Using a dip slide the responsible party will remove the dip slide from the protective Protocol cover and dip it into the basin of the cooling tower for approximately 3 seconds. The excess water will be removed from the slide and the slide will then be covered again and the sample sealed. The results are reviewed by the Water Treatment Manager and any action that may be required will be ensue. All test results of all Legionella species at or above the magnitude of level 4, as indicated in Table 1 of Chapter 8, will be reported to the Department within 24 hours of receiving the test results. Collection Location(s) Legionella Sample Samples are collected by Triumvirate Environmental staff and staged in a cooler on Protocol ice. Responsible Party for Sample results will be interpreted by Triumvirate Environmental and the Water Corrective Action(s) Treatment Manager.
