What nutrient balance is needed to degrade COD or BOD in different applications?
Aquatic applications, general waste treatment and anaerobic lagoons require a certain minimum nutrient balance for microbes to degrade the COD or BOD present. If the ammonia exceeds the level necessary for co-metabolism, then nitrifiers (contained in CF 1100, 1200, 1400, and 7110) may be added to handle the balance. If the phosphorus exceeds the level needed for co-metabolism, chemical binding, such as with dolomitic limestone, reverse osmosis or other means of filtration, may be required. Carbon: Nitrogen: Phosphorus = 100:6:3 Phosphorus levels as low as 1 will also work in these environments. Hydrocarbon remediation applications rarely have enough nitrogen and phosphorus present, so these must be added in proper proportion for the bacteria to co-metabolize them with the hydrocarbon waste. The level of nutrient supplementation must be precisely determined or pollution may be caused by excess nitrate or phosphate escaping into the environment. Carbon: Nitrogen: Phosphorus = 100:10:5 Ph
