What types of bio cultures are commonly used for wastewater treatment?

In wastewater treatment, various types of bio cultures are employed to enhance the process. Common bio cultures include activated sludge, which comprises microorganisms that digest organic pollutants, and nitrifying bacteria, which convert ammonia into nitrate. Additionally, specialized cultures like denitrifying bacteria are used to remove nitrates from the system. These bio cultures for wastewater treatment work together to efficiently break down contaminants, improving overall treatment efficiency and water quality.
