How is sea water desalination system work?

Seawater has high salt content, high hardness, high corrosiveness to equipment, and seasonal changes in water temperature make the reverse osmosis seawater desalination system much more complicated than conventional brackish water desalination system, and the project investment and energy consumption are much higher. . Therefore, through careful process design, reasonable equipment configuration to reduce engineering investment and energy consumption, thereby reducing unit water production costs, and ensuring stable operation of the system is particularly important.

System control

The design of the whole reverse osmosis seawater desalination control system is controlled by advanced computer programs at home and abroad.

The programmable controller PLC of the industrial computer operation station constitutes a distributed sampling control and centralized monitoring operation control system.

According to the process parameters, the high and low voltage protection switch is set, the automatic switching device, when the conductance, flow and pressure are abnormal, automatic switching, automatic interlock alarm and shutdown can be realized to protect the high pressure pump and reverse osmosis membrane components.

The inverter controls the starting and shutting down of the high pressure pump to realize the soft operation of the high pressure pump, saving energy and preventing damage of the high pressure pump and the membrane element due to water hammer or back pressure.

The program design can realize low-pressure automatic flushing before and after the reverse osmosis device is turned on and off.

Especially in the case of shutdown, the metastable state of concentrated seawater will be transformed into precipitation, contaminating the membrane surface, and the low-pressure desalinated water can automatically displace the concentrated seawater to protect it.

The membrane surface is not contaminated and the membrane life is extended.

Relevant parameters such as temperature, flow, water quality, and output of the system can be displayed, stored, counted, tabulated, and printed.

The dynamic process flow picture in the monitoring operation is clear and intuitive, and the system control simplifies the manual operation to ensure that the system can operate automatically, safely and reliably.
