Project Report on Waste Water Treatment

As mentioned above screenings are sometimes shredded and returned to the waste wa­ter flow. A hammer mill device is most often used for this purpose. Most often; a shredding device called a comminutor is located across the flow path and intercepted the coarse solids and shreds them to approx. 0.8 mm in size. These solids remain in the waste water.
