Since the physical method of water treatment was invented by Mr Klaus Wagner in 1988, it has been widely adopted across the globe, achieving a high level of customer satisfaction. This technology involves altering the physical form of water salts using vibration waves to impede the growth of micro – organisms. It aligns with the current trend towards chemical – free water treatment. Tetradom is committed to expanding the reach of this technology in China’s extensive industrial and commercial sectors, offering users and partners comprehensive technical support, and leveraging its 18 years of expertise. This technology has demonstrated its effectiveness in reducing costs, water usage, the risk of pollution, and generating social value. In 2022, a specialised sales company, EHS International Trading Company Limited, was established to promote the technology to the international market. EHS is looking for partners in all markets who are willing to join the Tetradom team, set up international distribution channels, and provide technical support and services.
