This presentation will review wastewater treatment considerations, accounting for varying hydraulic flows, organic loads, and other related considerations. The impact of these critical variables on wastewater treatment systems will be analyzed through design examples and case studies. Onsite wastewater treatment system component designs considered in this presentation include the septic tank, pump tank, treatment tank, and drainfield. Innovative and specific solutions to potentially challenging site conditions will be discussed.
After this session, attendees will be able to:
1. Explain how to identify critical parameters of wastewater influent for proper decentralized treatment system design.
2. Classify different facility types into typical influent strengths.
3. Identify the difference between hydraulic loading and how that affects decentralized treatment system design through the design of primary treatment tanks, secondary treatment tanks, and drainfields.
4. Identify design solutions for varying hydraulic and organic loads.
Ideal Audience: Designers, regulators, and installers.
Level: Intermediate
