The search for grit and grease removal equipment was fairly easy since the existing plant already had a Schreiber Grit and Grease removal system at the head of the plant.  The existing system had a proven performance and track record for several years.  Civil Engineering Consultants looked at the land available for the headworks portion of the project and determined that parallel grit and grease channels would fit the site the best. 

Schreiber uses air to agitate the waste stream so that grit will separate from the organics well.  The long rectangular channel design assures that the detention time and rolling effect created by the air allows for the best removal of grit.  Grit then settles to the bottom of the grit channel and is removed via a grit pump to the grit classifier. The flow into the grease channel is quiescent so that the grease can rise to the surface of the channel.  Air lances are positioned above the water surface and air is directed towards the surface to move the grease down the channel to the auger extraction point.  The new Schreiber Grit and Grease parallel channel design was selected and is performing well.
