Abstract

Une méthode de contrôle de la croissance des bivalves dans les systèmes deau de service statique ou semi-statique dune usine est présentée. À la détection dune augmentation de la concentration de larves véligères ou de bivalves à létape dinstallation, du potassium est introduit dans leau de service pour obtenir une concentration de cations de potassium allant de 10 mg/l à 150 mg/l pendant une période de 2 à 30 jours. Les méthodes sont particulièrement utiles pour contrôler la croissance des moules zébrées dans les systèmes deau de service de prévention des incendies.
