Tuesday AM Session #1 - Wastewater Myths, Forgotten Factors, and Pump Sizing

Thank you

Be sure to take the quiz to get your CEUs.

Description

Presentation #1: There are common industry misconceptions in the life cycle of an active wastewater treatment system. This presentation will address these misconceptions through design examples in an audience-interactive format.Addressing these myths can help industry professionals properly design, install, and maintain active treatment systems for optimal system performance and longevity.Some of the myths that will be addressed include misconceptions about septic system odors, the NSF certification (residential vs. commercial applications) and NSF testing specifications, advanced treatment unit performance, septic system sizing (hydraulic loading vs. organic loading), and advanced treatment system startup best practices. Septic system odors could depend on a number of factors including venting, plumbing (overall system design), and influent wastewater characteristics. With NSF-certified advanced treatment system design, it’s critical to understand how the treatment systems were tested and what they’re certified to. This allows the designer to specify the appropriate treatment technology based on required effluent concentrations. There’s also a misconception within the industry on system sizing based on hydraulic loading versus organic loading for advanced treatment systems.In what situations would a designer choose to incorporate organic loading into system sizing versus hydraulic loading alone. Lastly, this presentation will analyze the many myths regarding system startup.

Presentation #2: Climate and altitude have an effect on how the biology reacts in a wastewater treatment system but they are often times not included when sending a system out in the field.They also affect how mechanical parts work and perform in the field.This presentation will review how these factors influence the system performance with specific examples.

Presentation #3: Presentation discussing the difference between Sump, Sewage, Effluent, and Grinder pumps.Going over the SSPMA (Sump and Sewage Pumps Manufacturing Association) information on sizing a pump for the right application, what information is needed to size a pump system, explaining the concept of friction loss in different diameter pipes and determining TDH (total dynamic head), reviewing pump curves, reviewing the filters and screens used in pump applications focusing on drip irrigation systems and the explaining the different filters used on pumps, and on supply lines for drip systems (spin filters vs disk filters). When to use zones for drip systems, talking about size of zones and how the correct pump is needed to supply the zone sizing and why zoning is used in larger systems tying in the discussion on how zones allow the soils to rest between each pump cycle.
