The most probable solution when crustaceans have clogged the filters in a water treatment plant is to use a disinfectant that targets the specific organisms in question. This approach is effective because it directly addresses the issue of the crustaceans without the need for invasive manual removal or major disruptions to the system.

Using a disinfectant designed to target the specific type of organism can help to neutralize or eliminate the crustaceans, potentially restoring proper function to the filters. This method is often preferred in water treatment processes where maintaining continuous operation is crucial, as it minimizes downtime and disruption to the treatment workflow.

In contrast, shutting down the filters and removing the crustaceans physically would not only require significant time and labor but could also risk contaminating other areas of the system. While backwashing filters with ozone could be effective in some situations, high concentrations of ozone may not be specifically targeted at crustaceans and could risk damaging the filters or other parts of the treatment system. Therefore, utilizing a targeted disinfectant presents a more efficient and effective solution to the problem.
