Flow Diagram & Overview
The following tables provide an overview of the system, the key difference with the CCRO output is that the Feed Pressure is provided over the range of CC Cycles, accounting for the increasing osmotic pressure. The report starts with a Process Flow diagram as shown below (Figure 1). The streams are numbered for clarity. As CCRO technology is a semi-batch process, flows vary between PF and CC Mode. The flow rates referred to by the process flow diagram and accompanying table are average values.
