Ro system animation
The document describes the startup and shutdown sequence of a pressure exchange (PX) system. It involves 4 steps: 1. Starting the seawater pump and setting the PX low pressure flow rate. 2. Starting the PX booster pump to pressurize the low pressure stream. 3. Setting the PX booster flow rate and starting the main high pressure pump. 4. Shutting down involves stopping the main high pressure pump, PX booster pump, and seawater pump in sequence.
