Abstract
An exemplary apparatus (10), for removing buoyant pollutants having oil and debris atop a body of coolant, includes a pollutant collecting device (11), a pump (12) and a controlling module (13). The pollutant collecting device includes a hollow tub (12) and a collecting module (113). The collecting module is partially received in the hollow tub and is slidable relative to the hollow tub. The pump communicates with the hollow tub. The controlling module is configured for controlling the pump to draw coolant, oil or a mixture of coolant and buoyant pollutants into the hollow tub or out of the hollow tub.
