BOD, COD & Phosphate Management in Lagoons & Stormwater Ponds

Managing BOD, COD & Phosphates in Lagoons

Untreated sewage lagoons often face high biochemical oxygen demand (BOD), chemical oxygen demand (COD), Ammonia- Nitrogen (NH3-N), phosphate levels, total suspended solids (TSS), and more water quality parameters that can exceed effluent standards. High BOD and COD values are indirect measures of the presence of organic matter in water. The presence of organic matter, such as phosphates or bacteria will result in algae and bacteria growth, consequently decreasing dissolved oxygen (DO) levels and creating an anaerobic aquatic environment. 

The team at AEC has many solutions to manage BOD, COD, nitrogen-based contaminants, phosphate levels, ph, TSS, and more in lagoons and stormwater ponds. Bioaugmentation and aeration are the most natural and effective ways to reduce and manage BOD, COD, TSS, TKN, and more. AEC and Pond Pro Canada are leading distributors of all natural-bioremediation bacteria treatments. These bacteria treatments introduce beneficial bacteria, enzymes, and minerals directly into the system to help restore an aerobic ecosystem. As bacteria multiply they digest organic matter indirectly responsible for high BOD and COD levels in the pond, as well as the nutrients (i.e. phosphates) required by algae and weeds. Bioremediation also reduces odour and lowers pH.


Diffused aeration efficiently incorporates air into an aquatic system to increase DO content. Creating an aerobic environment encourages the natural breakdown of organic matter by aerobic bacteria. This process naturally and efficiently helps manage BOD, COD, and phosphate levels in lagoons and stormwater ponds. These chemical-free treatments are completely safe for livestock and wildlife.
