Hangzhou Dinghui Environmental Protection Technology Co., Ltd.
Founded in 2008 and located in Xihu District, Hangzhou City, Zhejiang Province, Hangzhou Dinghui Environmental Protection Technology Co., Ltd. is a national high-tech enterprise, a "Specialized, Sophisticated, Unique and Novel" enterprise in Zhejiang Province, and a participating compiling unit of the book Research and Practice of Intelligent Manufacturing in China's Glass Industry. We are specialized in the R&D, consultation, engineering contracting and equipment installation of wastewater treatment and reuse technologies for glass deep-processing.
Over the past 17 years, the company has accumulated abundant engineering experience in water treatment and recycling for the glass deep-processing industry. Our R&D team consists of 1 professor-level researcher, 2 postgraduate-degree holders, 5 intermediate engineers and 4 Class II registered construction engineers. Guided by the principle of integrity in conduct and steadiness in work, we have gained profound insights into the application of water treatment technologies in the glass deep-processing sector through years of practice, thus creating a path of win-win cooperation in the fields of wastewater treatment, reclaimed water reuse engineering construction, installation and services.
The company has long carried out technical cooperation and R&D with renowned domestic universities, striving to transform scientific and technological achievements into high-automation, superior-quality products that cater to customers of various demands. We are committed to establishing a win-win cooperation model with clients by providing professional services and high-quality products, aiming to become their long-term and reliable strategic partners.
After years of in-depth research and development in the field of wastewater treatment and reuse equipment for glass deep-processing, Hangzhou Dinghui has successfully launched the 1st, 2nd and 3rd generations of integrated glass wastewater treatment equipment. These products have been widely applied in the domestic and overseas glass wastewater treatment and reuse systems of numerous leading enterprises, including Flat Glass Group Co., Ltd., China National Building Material Group Co., Ltd., Kibing Group Co., Ltd., CSG Holding Co., Ltd., Fuyao Glass Industry Group Co., Ltd., Yaopi Glass Co., Ltd. and Xinyi Glass Holdings Limited. The completed projects have been operating stably with high automation level. The treated wastewater can be recycled to meet the production water demand, which reduces the enterprise operation cost, conserves water resources and cuts down wastewater discharge. Meanwhile, various types of our edge-grinding wastewater treatment equipment and pure water preparation system equipment have obtained the CE certification.
A Promise of Unshakable Integrity, A Legacy of Brilliant Excellence
Over the 17 years since its establishment, Hangzhou Dinghui Environmental Technology Co., Ltd. has built a strong professional R&D and service team, deeply engaged in the water treatment field. The core members of the team are all senior industry engineers, top technical experts and experienced project managers, with profound professional accumulation and rich practical experience in glass deep-processing wastewater treatment and reuse technologies.
Leveraging its cutting-edge submerged ultrafiltration (UF) membrane technology, Dinghui Environmental has earned recognition and established partnerships with leading industry players including China National Building Material, Kibing Group and CSG Holding Group. Its cooperation network covers benchmark brands in the glass deep-processing sector, and also includes diversified industrial giants such as East Hope Group and Conch Group. The preference of these well-known enterprises is a testament to the outstanding performance of Dinghui's products in wastewater treatment efficiency and water quality improvement capacity, and also highlights the brand’s professional strength and market recognition in the water treatment industry.
The SS Dual-Select Integrated Machine is a new-generation product developed from our company's glass wastewater treatment integrated machine, also known as the 3rd-Generation Glass Wastewater Treatment Integrated Machine. It eliminates the need for a large-scale vertical flow sedimentation tank at the front end, simplifying the process and reducing the floor space. Meanwhile, it significantly cuts down infrastructure and operation costs, shortens the project implementation cycle, and enhances process flexibility to meet the treatment requirements of glass deep-processing wastewater under different working conditions.
Raw water first passes through a 0.5mm fine screen to filter out impurities, then enters the immersion ultrafiltration tank, with an air blower providing aeration to enhance treatment efficiency. A vacuum pump and gas-water separator create a negative pressure environment to achieve efficient solid-liquid separation via the ultrafiltration membrane. Purified water is sent to the product water storage tank by a suction pump. A backwash pump and backwash tank handle online cleaning of membrane modules, while a chemical cleaning system performs in-depth maintenance for severe pollution. A drainage pump discharges waste liquid uniformly to the sewer pipeline. Integrating filtration, separation, cleaning and sewage discharge, the whole process realizes automation and resource utilization of wastewater treatment, adapts to the complex water quality of glass deep processing wastewater, and features stable operation and high purification efficiency.
Hangzhou Dinghui Environmental Protection Technology Co., Ltd. holds a range of qualifications and honors: including EU CE certification, dual-system certifications for occupational health and safety management and environmental management, recognition as a high-tech enterprise, and a certificate for participating in compiling the Research and Practice of Intelligent Manufacturing in China's Building Materials Industry volume. These credentials validate its technical capabilities and compliance strength.
