Oxidation-reduction potential (ORP) as a control parameter in a single-stage partial nitritation/anammox process treating reject water

摘要

BACKGROUND: Redox potential value (or pE) can be used as a monitoring parameter for deammonification processes treating rejectwater. In this study its use as a control parameter was investigated. Experiments were carried outwith a one-stage partial nitritation/anammox process in a 200 L moving bed biofilm reactor (MBBR) with 40% filled Kaldnes biofilm carriers.
