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.
Pre-filtration protects the water treatment plant
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.
