MBR Pilot Plant Development and DemonstrationThe filtration unit HUBER VRM 20 consists of a hollow shaft and six filtration modules that are placed around the hollow shaft. The biologically cleaned sewage is extracted through the membranes under a low pressure difference and supplied to the discharge through the permeate collection line. Ultrafiltration membranes (pore size 38 nm) with an active layer of PES are used. Due to the small ...
grindibility in atox raw millGrindability is an important factor for the characteristic of the brittle raw materials by the design the mills. As grindability depends on many unknown factors, hardgrove grindability index (HGI) is determined empirically using a sample mill, according to the following procedure. The device to measure the hardgrove grindability consists of a top rotating ring with eight balls of 1 in. (
