Replacing Coarse Bubble Aeration: A Video Lagoon Case Study

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 aeration […]

NitrOx Lagoon Nitrification Reactor Approved in Iowa

Due to the success of the pilot, the Iowa DNR has approved a full installation of Triplepoint’s NitrOx® Process for lagoon nitrification in De Soto. Like many Iowa municipalities, the City of De Soto required an upgrade to their lagoon system to meet more stringent ammonia effluent requirements. In this article, we’ll review the conditions […]

Fruit Processing Wastewater: A Video Case Study

Fruit processing wastewater is challenging to treat due to the seasonal nature of the industry and widely variable flows and loadings, with influent BOD levels much higher than typical municipal influent. Treated effluent, instead of being discharged, can be stored and used for crop irrigation, reducing the cost of external water sources. This video case […]

Wastewater Lagoon Mixing for Egg Processing: A Video Case Study

Lagoon mixing is a critical component of wastewater treatment: Robust mixing keeps BOD-consuming microorganisms in contact with the dissolved and suspended organic matter and prevents sludge buildup. Mixing is especially critical for egg processing wastewater, which is notable for high BOD and suspended solids, floating proteins, and the potential for odors. This video case study shows how Triplepoint […]

Wastewater Lagoon Expansion: A Video Case Study

What do you do when an industry wants to move to town and increase hydraulic and BOD loadings to the lagoon system? New jobs can be a boon to a municipality, but only if the infrastructure is capable of handling it. Coopersville, MI, faced this challenge when a dairy processor made plans to move to the community. […]

Replace floating lagoon aerators with Triplepoint Aeration, relieve O&M headaches

Case Study: City of Yerington, NV Yerington, Nevada, is a desert community of about 1,200 households in the western part of the state. Their wastewater is treated by an aerated lagoon system just north of town. Frustrated by the high energy costs and consistent breakdown of their floating lagoon aerators, the city turned to Farr West […]

Facility maximizes lagoon aeration efficiency, saves money

Replacing coarse-bubble system with Triplepoint’s Aerators saves sanitary district over 40% on electricity and maintenance costs. Energy consumption represents the highest operational cost for an aerated wastewater treatment lagoon system. Here’s how one sanitary district improved their lagoon aeration efficiency and reduced power, operations, and maintenance costs by replacing their obsolete coarse-bubble aeration system with […]

LRAS™ Advanced Lagoon Treatment Expands Capacity: A Case Study

Lagoons are a popular method of wastewater treatment for smaller municipalities—they are energy-efficient, easy to operate, and low maintenance. However, when a lagoon system reaches capacity or underperforms, sometimes the immediate reaction is to replace it with a mechanical plant, with its high capital and construction costs, operational complexity, and more demanding maintenance.

Missouri Lagoon Ammonia: Dealing with Changing Regulations

Missouri’s new Lagoon Ammonia effluent permits, adopted to reflect the U.S. Environmental Protection Agency’s new water quality criteria, are posing a challenge for wastewater lagoon systems, which were not originally designed for cold weather lagoon ammonia removal. These new Missouri lagoon ammonia regulations are especially burdensome for smaller municipalities, who may fear significant capital expense […]

Wastewater Dairy Lagoon Aeration: A Case Study

Wastewater dairy lagoon aeration is one method of treating byproducts of dairy processing. One of the benefits of utilizing a lagoon, as opposed to an aeration tank, is the flexibility wastewater lagoons have to accept the varying amounts of flow and BOD that are commonly the result of dairy processing. Having the right aeration system […]
