The patent application (Publication Number: US20240034648A1) describes an innovative electrochemical cell design for water treatment systems. The electrochemical cell comprises two chambers, each with an inlet and an outlet, containing an anode and a cathode, respectively. The chambers are connected by at least one ionic connection, such as a salt bridge or an ion-permeable membrane, to prevent mixing of liquid electrolytes. The system allows for the generation of different products, such as H2O2 from water or NaOCl from seawater, by applying a current across the chambers. Additionally, the system includes features like recirculating channels and shared electrolyte channels to enhance efficiency and control the process.

Furthermore, the patent application details methods for operating and facilitating the electrochemical cell system. These methods involve introducing saline aqueous solutions into the chambers, applying a current to generate specific compounds, and monitoring parameters like voltage and hydrogen concentration. The system can adjust the introduction of oxidizing agents based on these parameters to optimize performance and prevent the formation of hydrogen gas. The methods also provide instructions for connecting the system to sources of seawater and brine, highlighting the versatility of the technology for various water treatment applications. Overall, the patent application showcases a novel electrochemical system with advanced features for efficient and controlled water treatment processes.
