WEFTEC’ 2013 Lagoon wastewater treatment using Innovative bioaugmentation technology case study
Introduction and Problem Statement Lagoon wastewater treatment systems employ a combination of physical, chemical, and biological processes to treat wastewater. Lagoon wastewater treatment systems are simple, natural, energy efficient, and one of the most cost effective treatment options, especially for small and rural communities. Lagoon systems are easy to operate, require lower maintenance ...

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 ...

WWTP Sludge reduction case study
Introduction The City of Spring Valley, IL was seeking bioaugmentation to reduce the economic burden of sludge dredging and disposal and to evaluate the possibility of restoring the microbiological activity in the lagoon. The lagoon was flooded several times from the near-by Illinois River, which created different strata of inorganic silt/organic sludge and densely packed sludge at the lagoon ...

Aerobic Treatment Plant for Poultry Processing Effluent
Without stopping production, Fluence upgraded a major poultry producer's wastewater treatment to meet discharge limits A large poultry processing plant in Brazil was relying on an outdated aerobic lagoon wastewater treatment system that was unable to meet new government effluent standards. Without interrupting production, Fluence converted it into an activated sludge wastewater treatment system ...

MICROBE-LIFT® Technology Cleans Up Petroleum Lagoon in Israel - WASTEWATER TREATMENT
Crude petroleum that had been collected from a transport spill was collected and deposited in a 100,000-gallon containment lagoon in the Jordan Valley, with the expectation that the petroleum would biodegrade over time. After several months with little or no degradation observed, alternatives were evaluated to accelerate the petroleum breakdown. A recommendation was made to use bioremediation. ...

Constructed wetlands as an alternative restoration measure for shallow lakes
This paper deals with the consequences of cultural eutrophication and unconventional solutions for shallow lake restoration. Cultural eutrophication is the primary problem that affects especially shallow lakes, due to their physical characteristics (e.g. shallow depth, lack of stratification). Palic Lake, a very shallow Pannonian lake, received treated municipal wastewaters coming from the ...

Effect of polyaluminium chloride on phosphorus removal in constructed wetlands treated with swine wastewater
Total phosphorus (TP) removal in aged constructed wetlands poses a challenge, especially when treated with swine wastewater with high concentrations of phosphorus (P). Our earlier studies with anaerobic lagoon swine wastewater treatment in constructed wetlands showed a decline in P removal (45–22%) with increased years of operation. These particular wetlands have been treated with swine ...

Floating baffle system improves lagoon efficiency by 90%
Industries and municipalities that deal with wastewater treatment are concerned with improving the efficiency of their wastewater treatment facilities. Lagoon efficiency, cost effective treatment, and low maintenance are important factors when purchasing treatment upgrades. Environetics, Inc. took these factors inlo consideration when they designed the Director floating baffle System. ...

Mixing To Enhance Facultative Wastewater Lagoon Treatment
SolarBee® & GridBee® Are Leading The Way In most lagoons, sunlight causes a hard stratification at 12 to 18 inches of depth. The top water is warmer and thick algae populations are producing supersaturated dissolved oxygen (DO). The DO gasses off at the surface and is not readily available deeper in the pond for use by BOD-reducing bacteria. Meanwhile new inflow water may be ...

Abatement efficiency of municipal wastewater treatment plants using different technologies (Orbetello Lagoon, Italy)
Two small-scale municipal wastewater treatment plants (Neghelli and Terrarossa) discharging effluents into a lagoon of great environmental interest and highly stressed by tourism (Orbetello, Italy) were monitored over the year 2001. We evaluated plants' performances developing a general efficiency indicator of removal to select the suitable purification technology (activated sludge, Neghelli vs. ...

Keeping a City’s wastewater treatment lagoon safe from harmful algae - Case Study
Blue-green and green algae were choking a major lagoon in one Ontario city. Ultrasound helped where chemicals could not. Though algae can pose aesthetic concerns and are generally a nuisance, its presence in key water resources can be more than just visually disturbing. Such was the case in the Canadian province of Ontario, where out-of-control blue-green and green algae in a key supply lagoon ...

Assessment of lagoon odor emissions before and after installation of solar-powered circulators; Myrtle Beach water reclamation facility
Introduction The City of Myrtle Beach operates a large wastewater treatment lagoon in parallel to its mechanical treatment plant located off Mr. Joe White Avenue in Myrtle Beach, South Carolina. The lagoon system occupies an area of over 45 acres. The large, odor-emitting surface area, combined with encroaching development, has resulted in complaints against the City regarding odor emissions from ...

Wastewater lagoons – a new aeration concept
The use of wastewater treatment lagoons, or stabilization ponds, is a common practice for rural municipalities and industrial facilities. Through the years there have been numerous designs for these ‘sludge settling basins,’ ranging from facultative, partial aerated, and fully aerated systems. But the primary reason for these systems is to utilize relatively shallow earthen ponds, or ...

Case Study: Barboursville, the “Best Little Village in the state,” just got better
Barboursville, which bills itself as the “Best Little Village in the State of West Virginia,” has just completed an impressive upgrade to its wastewater treatment lagoon. What makes the upgrade impressive? Try this: Increased capacity of the existing lagoon from 600,000 gpd to 1,500,000 gpd. Had no disruption of treatment during construction. Total project costs of less than $250,000. ...

Using a continuous-fill, intermittent-discharge SBR to remove biological nutrients
Five years ago, the Town of Essex, in southwestern Ontario, decided to upgrade its facultative lagoon treatment systems with an alternative wastewater treatment plant — a continuous-fill, intermittent-discharge sequencing batch reactor (CFID-SBR) system, targeting even higher effluent quality. The CFID SBR process was designed by Premier Tech Aqua, which also provided major process ...
