CFD Modeling Lagoon Aeration: A Peek Inside the Black Box

CFD modeling lagoon aerationLagoon treatment has been referred to as a “black box” because the specific mechanisms of treatment are hidden below the surface. Computational fluid dynamics (CFD) modeling provides a peek inside this black box, demonstrating how various elements of a facility (such as depth, baffles, influent and effluent structures, aeration and mixing) work together to either help or hinder wastewater treatment.

In this article, we’ll discuss CFD as a tool to optimize lagoon systems, why we commissioned CFD studies of our MARS Aerator, and what the results say about the MARS’ mixing capability.

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.

lagoon nitrificationLike 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 that led De Soto to choose to pilot Triplepoint’s NitrOx® Process for lagoon ammonia removal, outline why NitrOx was the most attractive option, describe the pilot setup, and reveal the results of the pilot that led to the Iowa DNR’s approval.

LDIB-TV: Biological Lagoon Additives with Aquafix

To paraphrase an old saying, some companies that sell hammers try to turn every problem into a nail. We’re not that kind of company.

We manufacture lagoon aeration, among other things, and while we know that sufficient aeration and mixing in a lagoon can improve treatment and prevent problems like odor and sludge buildup, we also know that adding aeration is not always feasible. Continue reading

How meth lab discharge affects a wastewater lagoon

meth lab lagoonPretty much everything that happens in town eventually makes its way into the wastewater system. So what happens to your lagoon if there’s a methamphetamine lab?

An operator asked us whether meth lab discharge would upset his lagoon. Since meth labs are sadly not rare in rural areas, it seemed like a good topic to tackle. In this article, we’ll provide an overview of what having a meth lab in town is likely to do to your wastewater lagoon, and provide links to more detailed information. Continue reading

Why are there red streaks in my lagoon? About lagoon Daphnia

We love hearing from operators–their questions give us insight into what may be going on in other lagoon systems. An operator asked if we could identify some red bugs he saw floating on the edge of his lagoon. At first we thought midge fly larvae, which are little red worms that hatch into swarming clouds of nuisance insects (more on midge flies in our previous article, What are these red worms in the lagoon?). From the photo he sent us, however, the red streaks are a telltale sign of lagoon Daphnia. This gives us the perfect opportunity to discuss what they are, why they can cause red streaks in a lagoon, and what they indicate about treatment conditions. Continue reading

LDIB-TV: Controlling Lagoon Algae and Duckweed with Aquafix

lagoon algae and duckweedLagoon algae and duckweed are among our most covered topics, and no wonder–both are common in lagoon systems, especially during the summer. In this episode of Lagoons Do It Better TV, we revisit the topic from new angle: how these growths can be controlled with lagoon additives like algaecides, bacteria, and catalysts.

In this video, lagoon specialist Patrick Hill sits down with John Dinneen, leader of technical service at Aquafix (teamaquafix.com), a leading microbiological lab. Aquafix produces bacteria, micronutrients, catalysts, and biostimulants that improve wastewater treatment. Watch the interview and read below for highlights of the conversation and links to more information. Continue reading

Lagoon Phosphorus 101: A video overview of the why and how of lagoon phosphorus removal

Nutrient removal is one of the most pressing challenges facing lagoon operators. In this episode of Lagoons Do It Better TV, lagoon specialists Patrick Hill and Tom Daugherty discuss why lagoon phosphorus is being regulated and the methods available to meet increasingly stringent phosphorus effluent limits.

Lagoon TSS to BOD5: A Simple Ratio to Diagnose the Source of Problems

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 lagoon TSS to BOD5 in final effluent reveals about the source of suspended solids issues, and what can be done to correct it.

Spring Lagoon Stench: It may be normal, but is it inevitable?

spring lagoon stenchSpring is in the air, and for some wastewater lagoons, that means foul odors are in the air, too. Google “spring lagoon stench” and you’ll see articles from local newspapers across the country, each reassuring readers that the foul lagoon odors they experience every spring are “normal” and will soon pass. While spring lagoon stench may be normal, is it inevitable, or can it be prevented?

In this short article, we’ll discuss the causes of spring lagoon odors and what can be done to prevent them. Continue reading
