Session 3 – Collection Systems and Wet WeatherContact Hours: 2.0 Engineer 2.0 Wastewater

Moderator Dahlia Thompson, Hazen and Sawyer 8:00 am Utilities Use Peak Wet Weather Flow Management with Pile Cloth Media Filtration to Meet Permits 3.1 John Dyson, Aqua-Aerobic Systems, Inc.

In North America many treatment facilities struggle with handling peak wet weather flow conditions when they exceed the design capacity of the biological treatment capacity. Many facilities are using peak wet weather flow management techniques to handle these condition in CSS and SSS communities. This involves using auxiliary treatment or auxiliary dual treatment schemes within a treatment facility. The presentation will cover the technology options available to utilities to handle the large peak wet weather factors that utilities are experiencing. It will discuss how enhanced high rate treatment technologies such as pile cloth media filtration can produce an effluent quality equal to secondary treatment during wet weather event allowing a utility to meet permit requirements for parameters such TSS, BOD, ammonia, TP, etc. Good peak flow management during wet weather treatment involves maintaining performance of the biological treatment during wet weather flow conditions and combining auxiliary treated flow together to produce a high quality effluent that can be disinfected effectively.

8:30 am The Lure of Depth-Only Measurements for I&I Assessment 3.2 Jay Boyd, ADS Environmental

Over the past 40 years, area/velocity meters able to measure depth and velocity satisfying Q = AV have established themselves as the standard for accurate flow measurement. Recently, less expensive, depth-only monitors are being promoted as alternatives, with reported ability to calculate velocity. Less-than-ideal conditions in sewers influence variables, necessary for velocity calculations. Case studies examine influences that affect data reliability and raise awareness of how to achieve accurate, reliable results.


9:15 am Using Hydroxyl Radicals to Treat FOG, Prevent Concrete Corrosion and Treat Odors 3.3 in the Collection System, Wastewater Plant and Other Applications Suzanne Dill, Vapex Environmental

To mitigate the nuisance odor causes to residents, odor control is frequently required. Additionally, fats, oils and, grease (FOG) and microbial induced corrosion (MIC) are destructive elements in wastewater that can be difficult to control or eradicate. A powerful method that has been in use for over 15 years to treat odors are hydroxyl radicals. This presentation explains how hydroxyl radicals oxidize odors and eliminate FOG and corrosion with results in real-world applications.

9:45 am I&I Removal – Lessons Learned for Avoiding Pitfalls and Increasing Effectiveness 3.4 Kevin Draganchuk, CEA Engineers

Infiltration and Inflow (I&I) hydraulically overloads sewers and Water Reclamation Facilities (WRFs), causes sanitary sewer overflows (SSOs), and increases wastewater treatment costs. Excessive I&I causing SSOs or WRF permit violations can result in costly lawsuits or enforcement actions. Unfortunately, I&I reduction efforts often fall short due to inadequate source investigations, ineffective sewer rehabilitation, and the manner that I&I enters sewers, resulting in inefficient use of precious funds and continued potential for SSOs and permit violations.
