Device Testing: High-Efficiency and High-Uniformity Microwave Water Treatment System Based on Horn Antennas

Microwave heating has excellent potential for applications in wastewater treatment. This study proposes a highly efficient continuous liquid-phase microwave system to overcome the problems of low treatment capacity, dynamic range loads, and insufficient uniformity existing equipment. First, quarter-wavelength impedance-matching layer improves efficiency, been enhanced by horn antennas. Second, an experimental is developed. The simulation results are consistent, with achieving over 90% energy utilization different thicknesses concentrations salt water. Finally, simulations performed analyze efficiency at flow rates, salinities, dielectric properties, sawtooth structures. can efficiently heat loads wide including saline Generally, when permittivity varies from 10 80, loss tangent dynamically 0.15 0.6, more than temperature distribution (The coefficient variation COV < 0.5) be achieved. system’s modular design enables scaling up further boost processing capacity. Overall, provides high-throughput, high-efficiency, high-uniformity, large-dynamic-range water treatment, which promising industrial
