Consider installing floating baffles when: Designing or upgrading any pond, lagoon or tank where settling, biological treatment or disinfection depends on retention time (for example, maturation ponds, settling basins, clearwells or balance tanks) (Chatoyer Environmental 2025). ...
When aging lagoons meet modern regulations, choices must be made Wastewater lagoons have been around for decades. ...
Rather than replacing an entire system, strategic upgrades of lagoon systems can enhance performance while keeping costs manageable. What are some signs a lagoon system needs an upgrade? Sludge accumulation: Over time, lagoons accumulate sludge, which can cause operational inefficiencies and compliance issues. ...
While lagoon wastewater treatment makes sense for rural areas, its effluent may have trouble meeting discharge standards The U.S. relies heavily on lagoon wastewater treatment, with more than 4,500 systems, but widespread non-compliance with nutrient discharge permits is a persistent issue. ...
Figure 1 - Short circuited lagoon with exposed sludge buildup around the edges The town's administration and the golf club management company decided on a multi-phase program of sludge reduction with an upgraded diffused aeration system. ...
Problem Your lagoon has served your community or company well for so long but now modern regulations or sludge buildup make it untenable. ...
When the Town of Marana, Ariz., experienced rapid growth, quick but effective treatment solutions to their existing municipal lagoons were sought. The upgraded facility required meeting three basic criteria: (1) expanded capacity in the short term to 150,000 GPD; (2) enhanced biological treatment capability to allow some (or all) effluent to be re-used; (3) be ...
As a result, it will be necessary to upgrade many existing lagoons to achieve tertiary treatment ...
A pilot study was performed to evaluate the potential of an inert self-supported immersed fixed film media to upgrade aerated lagoons. Simultaneous organic matter removal and nitrification was assessed under different loading rates and temperatures (near 0 °C) using 12 laboratory-scale reactors operated in parallel. ...
Covering and insulating the 5 acre (2 hectare) anaerobic lagoon would be a key part of an overall plant upgrade which includes lagoon restructuring, new pipelines, and aeration cells. ...
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. ...
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? ...
The DPMC aerated lagoon is applicable to many small plants as a process upgrade to underperforming lagoons or as a new process. Prior to the upgrade detailed in this case study, the wastewater treatment plant (WWTP) serving the city of Corcoran, California, employed a conventional aerated/facultative (A/F) ...
Requirement The city of Folkston, Georgia, needed to upgrade its lagoon system to meet new regulation regarding Ammonia removal. The extensive system consists of primary lagoons, followed by a constructed wetland, and discharging the effluent into the Okefenokee Swamp. Challenge The upgrade project was to be accomplished with ...
Additional benefits of the system include: Operation of nutrient removal systems at low suspended-growth sludge ages, thereby reducing settling problems associated with long SRT nutrient removal systems Reduction of HRT required for CBOD removal Operational flexibility due to the relative simplicity of adding biomass carriers in response to growing loads This paper summarizes preliminary ...
