Calculating the Cost Of Grit

Calculating the Cost Of Grit

An aerated grit basin has an average efficiency of 50% meaning that around half of the influent grit that enters the system passes through into downstream processes. For a typical water treatment plant using an AGB, Cost Of Grit modeling suggests that the grit that passes through the basin costs the plant as much as 350,000 every year. Over a 25 year lifecycle this amounts

 · Aerated grit chambers are widely used for selective removal of grit. The spiral roll of the aerated grit chamber liquid drives the grit into a hopper loed under the air diffuser assembly (see Figure ). The shearing force of the air bubbles strips the inert grit of much of the organic material that adheres to its surface.
