Abstract: An exemplary apparatus (100), for removing buoyant pollutants from a polluted coolant, includes a collecting device (10) and a removing device (20). The collecting device includes a pollutant collecting structure (11) and a bi-directional pump (12). The pollutant collecting structure includes a hollow tub (112) and a collecting module (113) slidable relative to the hollow tub. The bi-directional pump communicates with the hollow tub and the removing device. The removing device includes a filter (21) and a pollutant removing structure (22) disposed on the filter. The filter includes a filtrating unit (211). The filtrating unit is partitioned into a first cavity (2132) and a second cavity (2133) by a partition sheet (213). The partitioning board defines a communicating gap (2131) for the first cavity and the second cavity to communicate with each other. The pollutant removing structure includes a removing member (221) for removing the buoyant pollutants out of the filter.

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.

Abstract: An exemplary apparatus (20), for removing pollutants atop a body of coolant, includes a filter (21), a pollutant removing structure (22), and a pump (23). The filter includes a housing (210), and a filtering unit (211) positioned in the housing for removing the pollutants from the coolant. The filtering unit is separated into a first cavity (2112) and a second cavity (2113) by a partition sheet (213). The partition sheet is spaced apart from a bottom surface of the housing to define a communicating gap (2131) for the first cavity and the second cavity to communicate with each other. The pollutant removing structure is positioned on the filter. The pollutant removing structure includes a removing member (221) for removing the pollutants out of the filter. The pump is configured for pumping the coolant into the first cavity of the filter.
