Sewage Screening

There are a number of ways that items can 'escape' from sewage systems and sewage treatment works, finding their way into rivers and the sea and possibly ending up on beaches. Sewage screening is important. One of the treatment processes at the beginning of sewage works is called sewage screening. Screens come in a range of sizes and shapes and their main function is to remove solid matter. Many works have been upgrading their screens and will have installed 6mm or even 3mm bar or mesh. 6mm bar screens will remove any objects that exceed 6mm in one dimension. A 3mm mesh screen will remove any objects that exceed 3mm in two dimensions.
