7 is to blunge the clay usually at about 15 to 20 percent solids to disperse the bentonite and release the grit sized particles such as quartz, which can then be removed by screening or by a degritting centrifuge or a hydrocyclone.
Finham currently consists of two separate inlet works, at the Sherbourne and the Sowe, each providing screening and degritting treatment before combining and passing forward to two separate primary sedimentation streams.
While primarily used to dewater fine materials, it can be used for degritting, desliming, rinsing, scrubbing and washing.
