Removal of dead and decaying zebra mussels from within a dewatered facility.
Zebra mussel control methods include both preventative and reactive strategies. By definition, preventative methods are designed to block the buildup of any zebra mussel population, while reactive measures are used to control a population that has already become established. Examples of reactive control methods are mechanical cleaning, high-pressure water jetting, carbon dioxide pellet blasting, freezing, scraping, scrubbing, pigging, and desiccation. Chemical and thermal treatments can be used as reactive treatments to clean a system and then used preventatively as regular maintenance to control further fouling. Selection of appropriate reactive control methods should be based on environmental and economic factors, ease of application, and the nature of application. If zebra mussels are at their adult stage, reactive control methods may have the added problem of getting the shells from the killed mussels out of the facility's water conduits.
