Phosphorus Removal in Wastewater Treatment | ATS Innova

Almost all wastewater treatment plants perform at least a secondary treatment, but this typically does not provide enough phosphorus removal. To meet the new requirements, facilities can do one of two things: 1) retrofit their plants to enhance biological treatment processes, or 2) add chemistry to help precipitate out the phosphate.
