Key Updates on Wastewater Management at the 2011 Smithfield Environmental Conference

This report highlights significant points discussed by Rocky Beem at the 2011 Smithfield Environmental Conference regarding wastewater management. Key topics include the status of wastewater training programs, notice of violations (NOVs), common regulatory issues, and recent trends in wastewater regulations. The training program upgrade encompasses new online courses completed by 143 employees, covering crucial topics such as anaerobic lagoon monitoring and trickling filters. The report also details improvements in wastewater parameters and highlights the need for responsive actions to permit changes and deteriorating conditions.

  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
