Distillation is one of the major "unit operations" of the chemical process industries, especially those connected with petroleum and biofuel refining, liquid air separation, and brewing. Laboratory distillations are typically batch operations and employ relatively simple fractionating columns to obtain a pure product. Processes of Waste Water Treatment: 4 Process (With Diagram) The operating sequence of a typical SBR is depicted in Fig. 57.5. The process is carried out in a sequence of five steps — filling, aeration (reacting) sedimentation (settling), decanting and idle. Several modifications and improvements have been made in the SBR for more efficient operation. Aerobic Digestion:
Filtration is a physical, biological or chemical operation that separates solid matter and fluid from a mixture with a filter medium that has a complex structure through which only the fluid can pass. Solid particles that cannot pass through the filter medium are described as oversize and the fluid that passes through is called the filtrate. Oversize particles may form a filter cake on top of ...
