TSS - Sources and Solutions and Flow Equalization
These presentations were recorded as part of the 2021 Mega Conference
Overview: Presentation #1: Total suspended solids (TSS) is found in all wastewater in varying amounts. The type of facility and activities influence the levels in the raw wastewater. This presentation will provide an overview of methods of quantifying solids in wastewater and typical levels in raw wastewater. The sizing of our primary treatment in septic tanks and the use of screens/filters will be discussed. The reduction of TSS in secondary treatment units such as aerobic units and media filters is another variable impacting TSS. If the levels are elevated it can impact the clogging of filters/screens, media filters, and soil treatment system. This presentation will discuss use, design, and management options to reduce the impacts of TSS on system performance and longevity.
Presentation #2: Flow equalization tanks are an effective tool for improving the performance of onsite wastewater treatment systems. Flow equalization tanks are typically placed in the treatment train after the first septic/trash tank. Water from the source is collected and time dosed to downstream treatment components. The first tanks are designed for the greatest peak flow rate, but downstream components can treat the water at an averaged flow rate. This averaged flow allows the downstream components to perform more effectively. The presentation will describe the purpose and function of the flow equalization tanks. The selection of the tank will be discussed and key components are identified. The tank components are discussed from a perspective of improving system performance and the associated operation and maintenance requirements. Buoyancy considerations are presented due to the risk of tank flotation. An extremely important part of the flow equalization tank system is the time dosed pump settings. The timer settings are presented. An example is presented on how to determine the timer settings for pump operation. The critical considerations when choosing the timer set points are presented and discussed.
