[0114] Example 1

[0115] The combination of an automatic dosing device and a real-time monitoring system enables automated dosing and cleaning during the membrane separation process. Sensors detect the pressure differential across the membrane element, automatically determining whether cleaning is necessary and ensuring efficient operation. Future improvements in system automation can be made by optimizing the dosing process and improving sensor accuracy.
