ASIA HKING LIMITED (AHK in short) is a high tech start-up with focus on the new material devleopment. To address the persistent environmental problem of wastewater and waste liquids generated from printing and dyeing, medical, chemical, food industries, and landfill leachate, the company has conducted full-chain research on the design and preparation of nano catalytic membrane materials, structural regulation, performance evaluation, mechanism analysis, membrane components, and equipment, accumulating extensive scientific research results and practical experience. Among them, the focus has been on selecting and optimizing nano catalysts that have high catalytic activity, strong anti-poisoning ability, and controllable costs, precisely coupling nano membrane catalysis with physical membrane separation to generate synergistic effects, and developing and cultivating a complete industrial chain covering 'material development - process design - equipment manufacturing - engineering operation,' proposing a novel sustainable water treatment technology solution with market competitiveness.
