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 of lagoon solids issues.

Lagoon Cyanobacteria: The Blue-Green Algae Blooms of Summer

lagoon cyanobacteria

Lagoon cyanobacteria can cause a thick scum on the surface of the water and nasty odors. During the summer, the combination of sunlight, warm water temperatures, high nutrient loads, and predation by higher life forms like Daphnia and rotifers can lead to rampant algal growth, or blooms. Cyanobacteria are classified by the EPA as harmful algal blooms, or HABs, because they cause eutrophication or dead zones and can even release toxins that are harmful or deadly to people and animals.

Lagoon Sludge Reduction In Situ: Methods of Removing Sludge in Place

One of the benefits of lagoons for wastewater treatment is their built-in sludge storage, which reduces the need for sludge handling. However, every lagoon will eventually require dredging to remove nonvolatile solids like grit.

lagoon sludge reduction

The mechanical removal of sludge is expensive and disruptive, so the longer a lagoon can go between dredgings, the better. In this article, we’ll discuss methods of lagoon sludge reduction in situ, without dredging.

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 diagnose what’s happening when air is going into the lagoon yet there’s insufficient DO to meet treatment requirements.

Lagoon Lemna: Pros and Cons of Duckweed in a Wastewater Pond

Lagoon lemna, or duckweed, has been a popular topic on our Lagoons Do It Better Facebook group lately. That’s because, like algae and sludge, duckweed is just one of those things that comes with the territory. In our latest episode of LDIB-TV, Patrick Hill gives the lowdown on duckweed. Watch the video and read below for highlights.

Wastewater Treatment Pond Odor Control for Spring Turnover

wastewater treatment pond

Unmixed wastewater treatment ponds can experience turnover in the spring, so it’s the time of the year when operators (and local residents) are most concerned about unpleasant wastewater odors. Although spring lagoon turnover and its accompanying odors may be normal and expected, that doesn’t mean they are tolerated. In this short article, we’ll explain what causes ponds to turn over and what can be done to mitigate odor issues.

Triplepoint’s NitrOx Lagoon MBBR: A Video Case Study

A lagoon MBBR is a tertiary treatment process added to a lagoon system for the purpose of ammonia removal through biological nitrification. Our previous blog post, Lagoon MBBR: Moving Bed Biofilm Reactors for Ammonia Removal, explains the process in detail.

Following is a video case study of Benton, Missouri. They upgraded their wastewater lagoon facility with a NitrOx Lagoon MBBR to meet their new low ammonia limits. Watch the video and read on for highlights.

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

lagoon 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 and lagoon laterals to help you to determine which method is best for your application.
