Optimisation of the Tertiary Treatment

It is not always possible to reach the desired treatment result with only pure biological treatment, especially in industrial wastewaters. These wastewaters contain substances that must be treated with great difficulty or that inhibit the biological treatment. In the field of municipal/domestic wastewaters, additional treatment steps might also be required, especially if relatively strict outlet values have to be considered.

In the interest of the client System S&P® offers complete solutions even for complex wastewaters. Therefore System S&P® offers well thought out further treatment technologies in combination with the rotating immersion disk technology and other treatment steps. The variety of possible process combinations allows for an individually optimized solution for these wastewaters.

It is possible, for example, to achieve a simultaneous precipitation of phosphorous in the biodisk tank by a flow proportional dosing of the precipitation chemical. This allows for even very strict outlet requirements to be reliably achieved.
In the field of industrial wastewaters, for example, problematic suspended matter can be dealt with, which allows for the COD to be removed by flow proportional dosing of flocculation chemicals. Dissolved non-biodegradable substances can be removed by a following chemical wet oxidation step.
