Municipal lagoons: Reduction of Total Suspended Solids & Odor

How do drastically reduce TSS and odors?

Clean water and proper sewage management stand as the cornerstone of public health, with their infrastructure being particularly vulnerable during catastrophic events like earthquakes, floods, and conflicts. When these systems are compromised, communities face immediate risks of waterborne disease epidemics, making the protection of clean water supplies a globally unified priority for organizations and institutions worldwide.

Water treatment processes serve the essential function of removing or reducing contaminants to make water suitable for various end uses, including drinking, industrial applications, and medical purposes. This treatment aims to either eliminate contaminants entirely or decrease their concentrations to acceptable levels, ensuring the water can be safely returned to the environment without ecological harm.

In wastewater treatment facilities, floating covers have emerged as an effective solution for managing both Total Suspended Solids (TSS) and odor emissions. These covers work by preventing sunlight penetration, thereby inhibiting algae growth and reducing TSS levels. This approach is particularly valuable in addressing the persistent challenge of offensive odors from wastewater tanks and lagoons, which can significantly impact nearby residents and often prove more effective than costly chemical treatments.

The effectiveness of floating covers varies by design, with permeable options like Hexprotect covers demonstrating superior performance in both odor control and algae elimination. Facility operators primarily seek solutions that balance economic efficiency in both initial investment and operational costs while minimizing maintenance requirements. This has led to a preference for modular covers over traditional solid covers, as they typically require minimal to no maintenance.

Research has shown promising results with alternative solutions such as air-filled balls, specifically the Armor Ball® system, when used as floating covers for outdoor manure storage. Studies have documented significant reductions in ammonia losses, with cattle slurry showing approximately 15% losses and pig slurry between 5% and 12%, compared to complete losses in uncovered control tanks, demonstrating the substantial environmental benefits of these covering systems.
