What is remediator?

As an AI language model, I do not have enough context to determine what specific type of remediator you are referring to. However, in general, a remediator is someone or something that deals with or solves problems or difficulties.

A remediator could be a person who specializes in solving a particular issue, such as an environmental remediator who specializes in cleaning up hazardous waste sites. Alternatively, it could refer to a product or technology designed to address a specific problem, such as a water remediator that removes impurities from water.
