You have decided to use chlorine to help control a Nocardia foaming problem. A typical benchmark is to initially apply ___________ for every 1000 kg (100 lb) of mixed liquor volatile solids (MLVSS)

In the context of controlling Nocardia foaming problems using chlorine, the appropriate initial benchmark application is crucial for effective treatment. When managing Nocardia, which can lead to foaming in wastewater treatment, the typical recommendation is to apply a dose of 4 kg (4 lb) of chlorine per 1000 kg (100 lb) of mixed liquor volatile solids (MLVSS).

This specific dosage is aimed at ensuring that there is enough chlorine present to effectively reduce the population of Nocardia bacteria, which thrive under certain conditions and contribute to foaming issues. The 4 kg dosage serves as a starting point before adjustments are made based on system response and monitoring results, emphasizing the importance of precision in chemical dosing in wastewater treatment practices.

Using an adequate and controlled amount of chlorine is essential to mitigate the adverse effects of Nocardia without causing harm to the overall biological treatment process or leading to harmful byproducts. It is important to follow these benchmarks closely to maintain the health of the treatment system and achieve the desired results.
