Water mixing in waste lagoons - New Insights into an Important Requirement
Man-made lagoons have been used worldwide for the treatment of domestic and industrial wastewater, it seems, forever. All waste lagoons were first designed and thoughtfully planned considering their locations, soil makeup, and waste reduction processes prior to being implemented. The biological process of organic waste reduction is always a consideration of waste lagoon designs. There are three ...

The Re-habilitation of 43 Year Old Waste Lagoons
In 1967 the City of Concordia, MO built a segmented lagoon system to handle the small town's waste requirements. The main industry in Concordia is a Tyson renderings plant, and the lagoon system was designed to also handle that plant's final waste and water polishing requirements. The lagoon system was a relatively standard design, consisting of an 18.7 acre primary lagoon, a 5.6 acre secondary, ...

Performance of a dual-power, multicellular, aerated lagoon system in Corcoran, California
A dual-power, multicellular, aerated (DPMC) lagoon system was designed and constructed for the city of Corcoran, California. The new process brought the plant into a full compliance with California Regional Water Quality Control Board (CRWQCB) effluent limits while saving approximately $110,000 per year in energy costs. The project was a modification of an existing aerated/ facultative (A/F) ...

Eliminating Sludge Islands in your Wastewater Lagoon
Old municipal and industrial wastewater lagoons have the tendency to build islands of sludge at various locations around the lagoon. It is most common for older lagoons to build such islands wherever wastewater enters the lagoons. Of course, this is because the solids entering the lagoon have enough weight to fall out of the water as flow velocity is reduced, so the solids pile up just after ...

Surface Aeration or Diffused Aeration
When designing lagoon aeration systems selection of optimum aeration components is critical to maximum performance, long-term operation and easy maintenance. Lagoon aeration is generally broken down into two major categories surface aeration and diffused aeration. Surface Aeration Lagoon aeration systems dating back to 1960’s were almost all surface aerators. Surface aerators are still ...

All You Need to Know About Aquarian Aerators - Case Study
Sustainable water management means ensuring that our ponds and lakes are getting a healthy amount of oxygenation, especially for water wildlife living nearby or in our ponds. The best solution for this is an aquarian aerator. Our aerators move water from the bottom of your pond to the top, generating a circular motion that revives your water and keeps it fresh for wildlife. This repeated action ...

Project - Lagoons
Lagoons make it possible to create pools with idyllic beaches that adapt to their surroundings and the size of the land they are built on, as well as delivering added value to any property development. The innovative design of these lagoons, adaptable to both new and already existing complexes, is a factor that increases the value of a property. The wide range of activities they are able ...

Performance of Floating Horizontal Aerators in Aerated Lagoons and Oxidation Ditches
INTRODUCTION When selecting aeration equipment to use for a specific application, issues to address include reliability, serviceability, capital cost, system appurtenances, and cost of operation and maintenance. Another important consideration is oxygen transfer rate (OTR). Horizontal floating aerators have relatively high transfer rates and have been used successfully in aerated lagoons and ...

Regina shoreline sewage lagoon, Regina, Sask., Canada - Case Study
When Stantec Consulting Ltd. of Regina, SK, Canada, won the contract to design a new sewage lagoon for the City of Regina, the site’s history provided a good indication that serious erosion control measures were called for. Constructed in the early 1960s, the Regina Wastewater Treatment Plan uses a series of lagoons to contain secondary effluent from its sewage treatment operation. With the ...

Tracer studies on an aerated lagoon
The city of Palmerston North, New Zealand, has two aerated lagoons as its secondary treatment facility. Interest about treatment efficiency led to an investigation into the hydraulics in the second lagoon to determine if further optimisation was viable. A tracer study using rhodamine WT was undertaken to ascertain the stimulus response output. Samples were also taken at 24 points within the ...

Wastewater Lagoon Aeration
One of the most common methods for treating high volume wastewater in rural areas are wastewater lagoons, also referred to as ‘wastewater treatment lagoons’. Lagoon aeration is often utilised as part of this process, in the form of floating or submersible mechanical aerators due to their low running costs and low maintenance requirements. As land prices are typically more affordable ...

Wetland Biofilter System provides year-round, cost effective treatment to over 1.5 million litres of wastewater
The success of early surface flow treatment wetlands in Canada was limited by hydraulic blockages and oxygen limitation due to freezing. From 1991 to 1996, Dr. Edgar Lemon, with the Friends of Fort George, researched a sub-surface vertical flow constructed wetland treating lagoon effluent at Niagara-on-the-Lake, funded by the Ontario Ministry of Environment (MOE) and the United States ...

A New, Cost-Efficient Way to De-sludge your Lagoon
Most small towns, all over the world, utilize lagoons for treating their wastewater. Many rural industries also utilize lagoons for storm-water and wastewater treatment. While industrial plants may be able to pay for activated sludge treatment of one design or another, small municipalities simply do not have a choice in treating their small populations’ wastes. If the town’s ...
