Phosphorus Removal
Phosphorus Removal is an important process in water and wastewater treatment that helps clean water by taking out excess nutrients that can harm the environment. It's like removing unwanted ingredients from water to make it safer for release into nature or reuse. Treatment plants use this process to meet environmental rules and protect water quality. This can be done through different methods, including adding chemicals or using helpful bacteria. When looking at resumes, you might see it referred to as "nutrient removal" or "phosphorus reduction" as well.
