Top 3 reasons rectangular basins are ideal for optimization.

I'll be discussing an application of CFD modeling and the patented technology we represent in Olympia, Washington. The Olympia plant faced challenges due to heavy rain and its location in a congested industrial area. To address the need for more primary clarifier capacity, baffle systems were implemented, resulting in a significant improvement in solids capture efficiency and doubling of treatment capacity.

In this video, I review a case study from Central Contra Costa Sanitary District (CentralSan) in Northern California.

This case study focuses on helping a Plant Manager understand why the performance of an existing primary clarifier rapidly declined above 10 mgd.

In this video, I discuss a case study from Dublin San Ramon Services District (DSRSD) in Northern California.

Many engineers view rectangular primary and secondary clarifiers as relics of the past. My opinion is they are underrated. My opinion is based on performance data from plants throughout the United States and the results from hydraulic modeling.

Managing SVI’s is important because the original clarifier design likely assumed average SVI’s and clarifier effluent is sensitive to the measurement. It is also one of the few variables that can be controlled by operators once a system is placed into service.

At Pacific Wastewater Optimization, "Our mission is to help achieve higher solids capture, energy savings, and treatment capacity from existing primary sedimentation and secondary clarifiers, for the benefit of water quality on Earth.’
