Top 10 Wastewater Lagoon Articles of 2017 from Triplepoint’s Blog

wastewater lagoon articlesWe’re gratified by the great response we’ve gotten to our lagoon blog. Our mission is to be a clearinghouse for lagoon topics and research, and to provide insight into how Lagoons can Do It Better. (If there are any topics you’d like us to tackle in 2018, post in the comments!)

As Steve Harris says in our video interview, just one small idea can revolutionize your lagoon system—improve treatment and help you to meet your permit limits. We hope you’ll look to our blog as a source for revolutionary ideas.

As we wrap up 2017, here’s a look back at the year’s most popular blog posts:

6 Tips to Remove Ammonia from Wastewater Lagoons

wastewater lagoon articlesRemoving ammonia from wastewater lagoons has become a hot topic over the past few years. State Environmental Protection Agencies have been introducing new ammonia limits for aerated wastewater lagoons. This is a problem because most wastewater lagoon systems were not originally designed for ammonia treatment. As a result, most lagoon systems will require some kind of upgrade.

In this article, we discuss one of the main processes by which to remove ammonia from wastewater lagoons, namely nitrification. In the event that your lagoon needs upgrades, this will help you narrow down your options. Read more…

Wastewater Lagoon Sludge: Treatment or Removal?

wastewater lagoon articlesMany wastewater lagoons suffer from excess lagoon sludge accumulation. That being the case, wastewater lagoon sludge treatment is a common challenge for wastewater lagoons worldwide. Excess lagoon sludge can lead to higher effluent levels of BOD, TSS and ammonia along with some terrible lagoon odors. For an example of what happens when sludge is allowed to accumulate too much, see our blog: Wastewater Lagoon Mixing Alleviates Odor & Sludge Issues.

This article, the second in a two-part series, focuses on the causes and subsequent effects on your wastewater lagoon when sludge starts to build up. Our first article, Causes & Effects of Wastewater Lagoon Sludge Explained, considered why sludge accumulates in your lagoon in the first place. Read more…

What color is your wastewater lagoon?

wastewater lagoon articlesAlthough regular and accurate sampling is critical for wastewater lagoon operators, you can tell a lot about a lagoon’s health and the quality of treatment you’re getting with a visual check of water and algae color.

In this article, we describe the characteristics of a healthy wastewater lagoon; outline the different common wastewater lagoon colors and their causes, such as algae and bacteria; and tell you what they might indicate about your lagoon’s health. Read more…

Lagoon Duckweed: Friend or Foe?

wastewater lagoon articlesDuckweed, or water lens, is a rapidly growing, invasive aquatic plant that loves wastewater lagoons due to the presence of nutrients ammonia and phosphorus. Since summertime is high season for lagoon duckweed, it seems like a good time to talk about it—what it is, what it does, and whether it’s a friend or a foe in your wastewater lagoon. Read more…

 

Lagoon Aeration Alternatives: An Overview

wastewater lagoon articlesLagoon Aeration is the process by which both oxygen and mixing are utilized in a wastewater treatment lagoon system in order to create an aerobic treatment environment. Through proper aeration and a retention time of typically 20–40 days, aerated lagoons are capable of producing effluents of below 10 mg/L BOD, TSS and, in warmer climates, ammonia/nitrogen below 10 mg/L. The purpose of this article is to briefly describe and evaluate different lagoon aeration technologies in terms of aeration, installation, and operation & maintenance. Read more…

Pros and Cons of Surface Aeration in Wastewater Lagoons

wastewater lagoon articlesSurface aerators are one of the most often utilized wastewater lagoon aeration technologies. When making any buying decision, it’s always important to be well informed. This blog post provides a full breakdown of surface aeration as it relates to wastewater lagoon treatment. Read more…

 

Using Wastewater Lagoon pH as a Diagnostic Tool

wastewater lagoon articlesWastewater lagoon pH is a common testing parameter that is easily taken for granted. Dig a little deeper, however, and pH can give you valuable clues about what’s going on in your lagoon and help you troubleshoot the source of effluent problems.

In this article we talk about what pH is and what various pH readings can reveal about the health of your wastewater lagoon. Read more…

Aerated Lagoons: 5 Design Factors to Consider

wastewater lagoon articlesAn aerated lagoon can be one of the most efficient, cost-effective, and low-maintenance methods of wastewater treatment. Because aeration can account for 50–60% of energy costs, it’s important to consider design conditions when determining the type and amount of aeration required. This article provides an overview of the factors, namely SOTE, SAE, aeration type, flow rate, and lagoon depth, that must be taken into account when designing an aerated lagoon system. Read more…

What are these red worms in the lagoon?

wastewater lagoon articlesWe’re often in the field, visiting wastewater lagoon facilities and learning about the challenges operators face. Last week, an operator in Georgia showed us a video of lagoon sludge swarming with tiny, wriggling red worms. Since we’re always interested in lagoon conditions and how they contribute to effluent quality, we decided to take a closer look at these creatures and examine why they appear, what they mean, and how to get rid of them. Read more…

The Nose Knows: Lagoon Odors Give Clues to Lagoon Health

wastewater lagoon articlesThe wastewater lagoon operator has many tools at his or her disposal to determine the overall condition of a lagoon. Lagoon sampling and testing, of course, are the main methods, but even without equipment, the lagoon operator can get valuable diagnostic clues from sensory information. In this brief article, we outline what different lagoon odors can reveal about lagoon health. Read more…
