Good pre-filtration protects the downstream process steps and water treatment apparatus. For each application we choose the most appropriate pre-filtration. This ranges from very simple systems such as sieve baskets or bow sieves to more automated installations with cleaning systems, for example rake grids, step screens or drum sieves.

Protecting expensive membranes in a membrane bioreactor imposes stricter pre-filtration requirements. Sometimes small details make all the difference, such as the choice of a drum sieve with round perforations to improve the blocking of hair.
