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. The mechanical removal of sludge is expensive and disruptive, so the longer a lagoon can go between dredgings, the better. In […]

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 […]

Winery Pond Odor Control: A Case Study

A winery pond or lagoon can be an ideal treatment option for process wastewater because it is relatively low-maintenance, sustainable, easy to operate, and cost-effective. A pond with sufficient capacity can easily cope with the peak loads and changes in influent volume and temperature common with winery wastewater. Like municipal lagoons, however, a winery lagoon […]

Diagnosing and Correcting Nutrient Deficiency in Industrial Lagoons

Nutrient deficiency, or the lack of sufficient levels of ammonia and phosphorus, can prevent an industrial wastewater lagoon from removing BOD adequately. In this episode of LDIB-TV, lagoon specialist Julie Hartwig explains how to diagnose and correct industrial lagoon nutrient deficiency. She has a BS in Civil Engineering from the University of Illinois at Urbana-Champaign […]

Lagoon Aeration Retrofit: A Video Lagoon Case Study

A lagoon aeration retrofit can improve treatment and save thousands of dollars in energy, operations, and maintenance costs. Replacing a coarse bubble aeration system with Triplepoint’s lagoon aeration maintains the mixing performance of coarse bubbles and combines it with fine bubble oxygen transfer efficiency to maximize lagoon treatment. Because Triplepoint aerators are portable, the retrofit […]

Preventing Fall Lagoon Odor Caused by Seasonal Turnover

October is here—time for football, apple cider, falling leaves, and seasonal lagoon turnover. Although less extreme than the spring transition, autumn’s cooler temperatures cause destratification and may trigger lagoon turnover and corresponding odors. In this short article, we’ll talk about the causes of fall lagoon odor and how to prevent it. What Is Seasonal Lagoon Turnover? […]

Replacing Fine Bubble Lagoon Aeration: A Video Case Study

Fine bubble aeration is a popular method of wastewater lagoon treatment. A fine bubble lagoon aeration system is installed at the bottom and releases tiny bubbles that slowly rise to the surface of the water. Because the bubbles are so small, they rise relatively slowly and have a very large surface area, which maximizes oxygen […]

Lagoon Midge Flies: How to Control Chironomids and Red Worms

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 […]
