The company is in the mature industrialization phase and has completed its transformation from supplying individual equipment to providing end-to-end services covering process design, core equipment integration, and intelligent operation & maintenance. Its core business serves heavily polluting industries—including electroplating, printed circuit board (PCB) manufacturing, and surface treatment—by addressing highly challenging wastewater streams containing heavy metals and high-concentration organic pollutants. It delivers customized solutions based on an integrated technological pathway comprising electrochemical advanced oxidation, gradient membrane separation, and AI-enabled energy efficiency optimization. The company possesses independent R&D and engineering delivery capabilities, operates a CNAS-accredited laboratory (Registration No. L9265), and holds 47 authorized patents (including 12 invention patents). Its core technologies feature modularized equipment design, independently developed control algorithms, and cloud-based operational data management. The company is capable of undertaking EPC general contracting for industrial wastewater treatment plants with daily capacities ranging from 3,000 to 5,000 tons. Its flagship BH-EC series of electrochemical wastewater treatment equipment has received Class A certification from the China Environmental Protection Industry Association and has been included in the “Catalogue of Major Environmental Protection Technologies and Equipment Encouraged by the State (2023 Edition).” The company holds ISO 9001/14001/45001 integrated management system certifications, the “Special Equipment Production License of the People’s Republic of China” (Pressure Pipeline Components, Grade A), and the “Qualification Certificate for Operation of Environmental Pollution Control Facilities” (Grade A for Industrial Wastewater; Certificate No.: Huan Yun Ying Liao Zi 2021-037). Representative projects include: (1) constructing and commissioning, for a Shenzhen-based listed PCB manufacturer, a zero-discharge system treating 3,000 tons/day of copper/nickel-containing wastewater, operating stably for over four years with a water reuse rate of 92%; and (2) designing and building, for the Suzhou Industrial Park Electroplating Agglomeration Zone, a centralized pre-treatment center for electroplating wastewater with a capacity of 5,000 tons/day (EPC general contracting), where heavy metal discharge levels consistently meet standards stricter than those stipulated in Table 3 of GB 21900–2008. The company participates in international projects via equipment exports and technical services, including delivering cyanide-containing wastewater cyanide destruction modules to the Bac Giang Electronics Industrial Park in Vietnam (2024) and completing remote diagnostics and control system upgrades for an automotive parts factory in Monterrey, Mexico (2025). Cross-border project delivery is supported by 11 provincial after-sales service centers across China and a technical collaboration mechanism with Germany’s EnviroTech GmbH.
