W-CE-014 Wastewater Treatment Ponds Planning

Wastewater Treatment Ponds Planning Webinar

The Wastewater Treatment Ponds Planning online PDH webinar is a part of our group of on-demand online webinars. This webinar will introduce you to the basic considerations in planning anaerobic, facultative and aerobic wastewater treatment ponds.

Wastewater treatment ponds existed and provided adequate treatment long before they were acknowledged as an “alternative” technology to mechanical plants in the United States. With legislative mandates to provide treatment to meet certain water quality standards, engineering specifications designed to meet those standards were developed, published and used by practitioners. The basic planning considerations of the various pond types are presented in this webinar

This webinar is intended for civil and environmental engineers who want to learn about planning for wastewater treatment ponds

Learning Objectives

At the end of the webinar, you will be able to:

  • Discuss anaerobic ponds that are deep impoundment, essentially free of dissolved oxygen (DO). The biochemical processes take place in deep basins, and such ponds are often used as preliminary treatment systems.
  • Explain how anaerobic microorganisms convert organic materials into stable products, such as CO2 and CH4.
  • Explain how the growth rate and metabolism of the methanogenic bacteria can be adversely affected by small fluctuations in pH substrate concentrations and temperature, but the performance of acid-forming bacteria is more tolerant of a wide range of conditions.
  • Describe why the design of anaerobic ponds is often based on organic loading rates, surface or volumetric loading rates and derived from pilot plant studies and observations of existing operating systems.
  • Describe technology associated with conventional facultative ponds to treat municipal and industrial wastewater.
  • Classify aerobic ponds by the amount and source of O2 supplied, mainly through mechanical or diffused aeration rather than by algal photosynthesis.
