Presentation Transcript

  1. Wastewater Updates Rocky Beem 2011 Smithfield Environmental Conference

  2. Key Points • Wastewater Training Status • NOVs • Common Issues • Regulation Trends • Upgrades

  3. Wastewater Training Program • Articulate Online Training – Active • 143 Employees Completed • 18 Courses : Two New Courses • Trickling Filters • Anaerobic Lagoon Monitoring • Very little activity • New individuals added – no activity

  4. New Course

  5. Anaerobic LagoonMonitoring • 25 minutes – shorter • Very detailed biology • Performance Monitoring • Indicators • Troubleshooting

  6. Other Courses Under Development • Wastewater Process Monitoring (In Progress) • General Monitoring Needs • DAF used as an example (applicable to most) • Activated Sludge Process Monitoring • Anaerobic Lagoon Monitoring (Complete) • Nitrification and De-nitrification • Data Management and Use • Case Studies

  7. CEU Approval Update

  8. NOV Status (88% Wastewater)

  9. 70% of NOV’s from 22% of Plants Notable Improvements

  10. Wastewater NOV Parameter • O&G, BOD & TSS Lower (DAF) • TKN, NH3 & Total N Increased • Fewer Admin Issues

  11. Wastewater Issues • Nitrogen (1/3 of NOVs) • Push for permit limits (EPA Effluent Guidelines) • Low DO = Loss of Nitrification • Aeration Capacity (diffusers), load, temp • DAF Performance • Erratic Flow (variable, too high) • Coagulant Performance (pH, flow proportional) • Aeration System

  12. Biological Wastewater Treatment • Anaerobic Lagoons • Loading – grease toxicity • Cleaning (short-circuiting, volume, grease) • Toxics (quat) • Activated Sludge • Aeration issues • Clarifiers (capacity, filamentous bulking)

  13. Regulatory Trends • Maryland – Wastewater Operator Certification • Permit Limits – Nitrogen • TMDL’s – Chesapeake Bay, Mississippi R., State & Stream Specific • Fecal • Nutrients (N & P)

  14. Wastewater Facility Maintenance • Spills related to wastewater drains • pH probe fouling or failure • Electronic Controls • DAF controls (hardware and software) • pH neutralization systems • Flow meter calibration

  15. Facility Upgrades • Response to changing loads (increase or decrease) • Response to changing permit limits • Aging / obsolete equipment • Efficiency / Cost Improvements • Automatic Operational Controls • Chemical Feed (coagulants, pH neutralization)

  16. Final Thoughts • Check Permit Expiration Date ? • Renewal Application: 180 days prior • Improve Process Monitoring • Influent and Effluent • Respond Quickly to Deteriorating Conditions
