Controlling Algae in a Wastewater Lagoon
In wastewater lagoons, single cellular algae can cause significant problems by effecting DO, pH, and TSS levels. While algal growth does provide some benefit in reducing nutrient levels within the lagoons, it is imperative that the algae be controlled so as to minimize the negative impacts on the water quality in the lagoon effluent. This article explores the impact that Bio-Domes have had on ...

PMMA-titania floating macrospheres for the photocatalytic remediation of agro-pharmaceutical wastewater
Antibiotics such as tetracycline are used on a large scale in agriculture, and can become concentrated in wastewater lagoons that are used in conjunction with confined animal feeding operations. Solar-illuminated titanium dioxide can be used to photocatalytically degrade aqueous tetracycline, but its application in a lagoon environment requires that the photocatalyst be supported on a ...

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 ...

Aerators and mixers enable cost savings, reduce biosolids buildup - Case Study
Problem The town of Monroeville, Ala., faced aeration and mixing issues, sludge buildup in one of its wastewater lagoons, and power bills of $12,500 per month after a major employer relocated its garment manufacturing facility. The company had generated about 90 percent of the wastewater entering the lagoon, and its fees covered 90 percent of the operation and maintenance cost, which included ...

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 ...

42% solids reduction in industrial lagoon system - Case Study
Drylet was tasked with applying its solution to a facility that was experiencing difficulties with breaking down accumulated solids in its wastewater lagoons system, compromising performance. The covered anaerobic lagoons had become walkable as if paved with concrete, while flaring had dropped from 12 to 2 hours daily. Mechanical dredging would have destroyed the established AD ecosystem in the ...

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 - Mazzei airjection aeration system solves odor and nutrient problems for California Carrot Packing Plant
Large Lagoon Odor Control & Stabilization for Land Application at Grimmway Farms Carrot Packing Plant. Kern County, CA The Problem: A carrot packing plant was having severe odor problems due to septic conditions in their truck washout water holding lagoon. In addition, nutrient and nitrogen levels were becoming an issue for land application of the wastewater for crop production. The ...

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 ...

Case study - Wastewater lagoon cover stops odor complaints
Problem: United Liquid Waste Recycling (ULWR) successfully recycles food and beverage waste into valuable by-products such as fertilizer. Odors from their anaerobic treatment process needed to be stopped to enable ULWR in Watertown Wisconsin to expand. Their two lagoon anaerobic digesters needed an affordable system to control odors. ULWR injects their valuable fertilizer into farm fields twice ...

Linking sanitation and wastewater treatment (WST)
In both developed and developing countries, centralised and on-site wastewater treatment systems have been developed for a long time. The main function of the wastewater treatment plants (WWTPs) should be removal of pollutants including organic carbon, nitrogen and phosphorus. Technologies applied to WWTPs are mostly with biological functions such as activated sludge, stabilization reservoir, ...
