stepfed
Stepfed is a term used primarily in the context of chemical and environmental engineering, particularly in wastewater treatment processes. It refers to a treatment configuration where the biological treatment stages are divided into multiple sequential steps, each with a specific function aimed at optimizing contaminant removal. The term "stepfed" originates from the "staged-feed" approach, which involves feeding the influent into different parts of the system in stages, often at different points along a treatment train.
In wastewater treatment, stepfed systems are designed to enhance nitrification and denitrification by controlling oxygen and
The advantages of stepfed configurations include better process control, increased treatment capacity, and improved effluent quality.
In summary, stepfed systems represent a strategic approach in biological wastewater treatment that aims to optimize
