<p>The apparatus has a wastewater drip tray (3) for collecting cooling water of a grinding machine through a primary filter (2). A pump (4) pumps the collected water so as to circulate the collected water through a filtering device (6) for removing polluting particles such as residues obtained from grinding of a glass, where the filtering device includes a replaceable filter cartridge (7). A recirculating pipe (11) recirculates the purified water by using the power supply of the grinding machine.</p> |
