WWTP Bayer AG, Deutschland
The Microflotation units with patented AQUATECTOR® Microfloat® technology were put into operation in the year 1997 at Bayer AG, Uerdingen.They serve the purpose of tertiary and reduction of TSS, COD and turbidity. Here, microflotation replaces sand filtration.
The enviplan® microflotation serves as supplementary processing stage for the wide-ranging separation of TSS of the completely biologically purified waste-water of Bayer AG. Beside the further reduction of the cumulative parameter COD, the duty of the flotation is to secure the monitoring values for unfavourable conditions of the purification plant at the outlet. For the wide-spread application of the sand-filtration as processing stage in the purification technology, the flotation represents a high-performance, highly variable and cost-effective processing alternative. The energy requirement of the entire plant lies at < 7,5 Wh per m³ of treated waste-water. About nine million cubic meter of water can be subsequently processed with the new system yearly. Dr. Kuhn as assistant head of factory, responsible for environmental protection: “The enviplan® Microflotation ensures that the COD decreases further. In it, we are seeing a further contribution in the sense of the Responsible Care”.
