To ensure wastewater treatment objectives are met, a lagoon aeration system design must be customized for its specific application.
In this video, Patrick Hill outlines the facility details we use to calculate aeration requirements and customize a lagoon aeration system design. He’ll also review common pitfalls and often-overlooked factors that can result in insufficient treatment. Watch the video on our Triplepoint You Tube channel and read below for highlights.
Lagoon midge flies, or chironomids, are common during warm summer temperatures, and swarms of them can drive local residents indoors. Midge fly larvae, or red worms, in a lagoon provide insight into lagoon conditions and their effect on effluent quality. Read on to learn why they appear, what they indicate about lagoon conditions, and how to control them. Continue reading →
Smelly lagoons have created the perception that wastewater lagoons don’t work and should be replaced with mechanical plants. Triplepoint HQ is six miles as the crow flies from the Stickney (aka “Stinkney”) Water Reclamation District, which serves the Chicago area and is the world’s largest wastewater treatment plant. Our coworkers who live a little closer to the facility can tell you on certain days when the wind is blowing the wrong way, treatment plants smell! A properly functioning lagoon is for the most part free of objectionable odors; in fact, a smelly lagoon is announcing that it’s not working optimally.
In this video, Triplepoint’s Patrick Hill describes lagoon odors and what they mean and shares some options for correcting the conditions that cause odor. Watch the video and read below for highlights. Continue reading →
Land application is the most common disposal method for treated wastewater in the U.S., and the preferred method in many states. Land applying effluent can reduce demand for fresh water, provide nutrients to soil, and keep potential contaminants out of waterways. For lagoons, it may also be a way to avoid having to meet ammonia discharge limits. Watch our video on the pros and cons of land application for lagoon effluent and read below for highlights.
Summer ammonia removal via nitrification is less of a challenge for lagoons than cold weather ammonia removal, as nitrifying bacteria are temperature sensitive and thrive in warmer water. The interplay between algae and bacteria, dissolved oxygen, pH, and temperature determines the pathway and rate of nitrification. Watch our video, 6 Key Factors for Nitrification, then read below for tips on how a lagoon can be optimized for summer ammonia removal. Continue reading →
Hydraulic fracturing, or fracking, is the process of injecting pressurized water, chemicals, and sand into the ground to extract shale oil and natural gas. While fracking has transformed energy production in the U.S., it requires a lot of water and thus creates a lot of wastewater, which must be treated and disposed of safely. In this video interview, Triplepoint’s resident expert, western regional manager Tom Daugherty, gives the lowdown on fracking wastewater and how frac ponds can be economically upgraded with MARS aeration. Read below for highlights and links to more information.
Duckweed, or water lens, is a rapidly growing, invasive aquatic plant that thrives in wastewater lagoons due to the presence of ammonia and phosphorus, which act as fertilizer. Since summertime is high season for lagoon duckweed, it’s a good time to revisit the topic—what duckweed is and what it does, and review some methods of duckweed control. Continue reading →
Coarse bubble aeration for lagoons has fallen out of favor, mainly because of its inefficiency compared to fine bubble aeration. While coarse bubble aeration provides excellent mixing performance, it doesn’t transfer oxygen as well as fine bubble does, requiring higher energy expenditures.
This video case study shows how replacing coarse bubble aeration with Triplepoint’s MARS aeration allows a municipality to save money on energy and produce high quality effluent for beneficial reuse in irrigation. Continue reading →
Spring is the time of the year when unmixed lagoons turn over, so it’s also the time of the year when operators (and local residents) are concerned about wastewater lagoon odor control. 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 lagoons to turn over and what can be done to mitigate odor issues. Continue reading →
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.
