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 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.
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.
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.
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 Microbiology: Meet Your Bugs is the first webinar presented by Julie Hartwig, Triplepoint’s regional sales manager for eastern and southern states. Julie knows her stuff: She has a BS in Civil Engineering from the University of Illinois at Urbana-Champaign, a master’s in Environmental Engineering from Penn State, and hands-on experience in wastewater troubleshooting as a rep for a major water technology company.
If you missed her webinar, you can find it below and on our You Tube Channel. We’ve also created an On Demand channel to make our webinars available for you to watch at your convenience: We call it Lagooniversity and hope you’ll check it out!
Industrial lagoons offer cost-effective, sustainable wastewater treatment. In our latest video, Triplepoint’s Julie Hartwig shares her experience working with industrial wastewater operators to highlight the huge advantages lagoons can provide for industrial facilities. Watch the video and read on for highlights.
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.
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.
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.
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.
It’s our belief, our motto, and our mission. Lagoons provide reliable, cost-effective, low maintenance wastewater treatment, and should be reinvented, not replaced. We’ve dedicated our 30+ years of lagoon engineering expertise to innovating technologies that leverage existing infrastructure while minimizing capital expense. Our cutting-edge lagoon process solutions include efficient lagoon aeration and mixing, cold weather ammonia-nitrogen removal, advanced lagoon treatment, and tertiary phosphorus removal.
