Cleaning lead containing waste water in a purification plant (7), comprises centrifugating the waste water in the purification plant, and recycling the clear water in the purification plant during centrifugation of waste water into a lead-containing centrifugate and separation of the clear water. An independent claim is also included for the production- and purification plant for carrying out the method, comprising at least one production plant for lead-acid batteries and the centrifuge for separating the waste water from the production plant in centrifugate and clear water, and a device for recycling the clear water from the centrifuge into the production- and purification plant. |
