Aquamite: A Deep Dive

Here's a breakdown of the Aquamite electrodialysis water treatment system, organized into chapters. Note that some information requires further details about the specific Aquamite systems offered by Ionics, Inc. This response provides a framework that could be filled in with more specific product information.

Chapter 1: Techniques

Electrodialysis with Aquamite

Aquamite utilizes electrodialysis (ED), a membrane-based separation process driven by an electric field. The core of the process involves:

• Specialized Membranes: Aquamite employs ion-selective membranes, alternating cation-exchange membranes (CEMs) permeable to positive ions and anion-exchange membranes (AEMs) permeable to negative ions. These membranes are crucial for separating ions from water.
• Electric Field: An electrical current applied across the membranes creates an electric field, forcing ions to migrate across the membranes. Cations move towards the cathode (negative electrode), and anions move towards the anode (positive electrode).
• Concentration and Dilute Streams: The system creates two streams: a concentrated stream containing the removed ions and a diluted stream with reduced ionic concentration. The desired product is the diluted, purified water.
• Stack Configuration: The membranes are arranged in stacks or cells, with spacers creating flow channels between the membranes to ensure even flow distribution and prevent membrane fouling. The number of cells determines the overall system capacity and treatment efficiency.
• Process Optimization: Factors like current density, flow rate, and membrane type are carefully optimized to achieve the desired level of purification and energy efficiency. Aquamite's technology likely incorporates advanced control systems to monitor and adjust these parameters in real-time.
