Wastewater treatment plants - Part 13: Chemical treatment - Treatment of wastewater by precipitation/flocculation; German version EN 12255-13:2023
Abstract
This document specifies the requirements for chemical treatment of wastewater by precipitation/flocculation for removal of phosphorus and suspended solids.The application of polymers is not described in this document.Differences in wastewater treatment throughout Europe have led to a variety of practices being developed. This document gives fundamental information about the practices; this document has not attempted to specify all available practices.Detailed information additional to that contained in this document may be obtained by referring to the bibliography.NOTE Chemical treatment may be performed in combination with primary and more commonly with secondary treatment, but it may also be performed as separate tertiary treatment, usually in combination with filtration (see EN 12255-16). Chemical treatment can provide a potential contribution to the circular economy through the recovery of materials, such as phosphorus, from wastewater or sludge.
