plants. When the cane is cut, rapid deterioration of the cane begins. Therefore, unlike sugarbeets, sugarcane cannot be stored for later processing without excessive deterioration of the sucrose content. A simplified process flow diagram for a typical cane sugar production plant is shown in Figure 9.10.

Turbidity is the measure of the cness or haziness of water. More specifically, it's the measure of how light reflects off of suspended particles in water – specifically particles such as proteins, minerals, bacteria, algae, dirt and oil. The cer the water is, the higher its turbidity will be. It is not a measure of actual particles ...
