Wastewater Pond DO: Where Did the Dissolved Oxygen Go?

A wastewater pond requires sufficient Dissolved Oxygen (DO) to satisfy Biological Oxygen Demand (BOD) and Nitrogenous Biochemical Oxygen Demand (NBOD). Without DO, a pond can experience odors and high effluent BOD and can even go septic. Often DO problems can be resolved quickly by improving oxygen transfer or adding more air. However, it’s important to […]

Lagoon Solids: Using the TSS to BOD5 Ratio to Diagnose Treatment Problems

Biological Oxygen Demand (BOD) and Total Suspended Solids, or TSS, are standard testing parameters for wastewater lagoons. The ratio between the two numbers can provide valuable insight into the source of the TSS. In this article, we’ll take a look at what the ratio of total suspended solids to BOD5 in final effluent reveals about the cause […]

Lagoon Aeration Efficiency: Understanding the Alpha Factor

The alpha factor is the single most elusive, overlooked, and abused element in the design of lagoon aeration systems. It is a catch-all factor used in the Field Transfer Efficiency equation to correct for the difference between clean water ASCE testing and “dirty” water use. It corrects for aeration type, bubble size, and wastewater contaminants, […]

Lagoon Aeration System Design: Individual Air Lines vs. Fixed or Floating Laterals

A lagoon aeration system will require some method to convey air from the onshore blower to each aeration unit. Two distribution methods are typical: individual air lines or lagoon laterals, either submerged and fixed to the bottom; or floating on the surface. In this article we’ll compare the benefits and drawbacks of individual air lines […]
