<p>The apparatus for purifying and reprocessing coolants and/or lubricants is to be further developed in such a way that the reprocessing steps, which become necessary during quasi-continuous operation, of the filter media can be carried out at low cost in terms of personnel, apparatus, material and disposal. For this purpose, a backwashing circulation which is to be effective cyclically for at least two membrane filters is provided, the discharge thereof leading into a settling tank which is provided with a take-off for sediments, and whose overflow is returned into the coolant and/or lubricant circulation.</p> |
