If they continue to be within the wastewater, they bring on overfertilisation of water bodies and enrichment with nutrients, which can cause ineffective plant expansion (eutrophication) damaging into the ecosystem.

In modern plants the screens are cleaned mechanically, and the material is promptly disposed of by burial within the plant grounds. A comminutor can be used to grind and shred debris that passes from the screens. The shredded materials is eliminated afterwards by sedimentation or flotation processes.
