Ceramic filter disc are vacuum-disc filters comprised of sintered alumina sector plates with uniform micro-pores. The micro-pores create suction through capillary action and once wetted, the filter medium allows only liquid to pass through during the filtering process. A filter cake forms on the surface of the disc and is removed by a …
Glucose is the ultimate organic starting material from which all other organic carbon compounds can be synthesized in nature. The single carbons of six carbon dioxide molecules are stitched together to form glucose by photosynthetic organisms. The energy for this reaction is provided by hydrolysis of adenosine triphosphate (ATP) to produce …
