Sewage treatment makes every drop of water valuable

As an enterprise possessing world-leading water treatment technology, CITIC Environment is committed to promoting industry development with its technological advantages, and continuously improves wastewater recycling and effluent standards, making unremitting efforts to improve water resources utilization and ensure urban water safety use. 

Technological innovation builds core competitiveness. Membrane manufacturing is the core business of CITIC Environment. CITIC Envirotech firmly grasps advantages of membrane R&D and manufacturing. Its subsidiary Memstar is one of the very few world-leading manufacturers and suppliers which possesses full-spectrum capabilities in R&D, production, and application for membrane products including Microfiltration (MF), Ultrafiltration (UF), Nanofiltration (NF) and Reverse Osmosis (RO) membranes. O2, an environmental protection technology assessment group in UK, has authenticated Memstar’s independently developed PVDF hollow fiber, considering its comprehensive performance ranks top three globally. In 2021, CITIC Envirotech set up R&D Institute, and new patents reached 35 for the whole year.

Model innovation leads industry development. Relying on world-leading membrane products, CITIC Environment has applied MBR (membrane bioreactor) technology, continuous membrane filtration (CMF) technology and reverse osmosis (RO) technology to various water treatment projects, and has made remarkable achievements in areas like difficult industrial wastewater, high requirements large-scale municipal wastewater and drinking water. The wastewater treatment technology with high efficiency and low energy consumption realizes its better effect via MBR membrane equipment manufacturing, technology optimization and upgrading and other combined technologies.

In addition, CITIC Environment pioneers the comprehensive application of both Memstar membrane and buried sewage plant, continuously exploring new technologies and paths for energy conservation, consumption reduction, and quality and efficiency improvement through fine management and process optimization. This has produced a wide range of economic and social benefits in urban land saving, operation cost reduction and sewage recycling improvement. CITIC Envirotech completed upgrading and expansion of Hebei Bazhou sewage treatment plant in 2021, and successfully finished water supplying of Pinghe river basin treatment project, contributing to building an ecological Xiong’an which is "blue and green, fresh and bright, water and city blending together". 1-1.jpg

Solid waste disposal turning waste into treasure

With the development of national industrialization and urbanization as well as improvement of people's living standards, the dilemma of industrial waste pollution and household waste siege became increasingly prominent . CITIC Environment treats solid waste from the source with the whole industrial chain service advantages, and promotes coordinated development of harmless domestic waste and recycling of hazardous industrial waste, so as to provide the public with a more livable urban environment and a cleaner natural environment.

Harmless waste disposal makes life better. Since China encourage domestic waste incineration power generation from 2000, CITIC Environment’s subsidiary Chongqing Sanfeng Environment took the lead in introducing and optimizing the German Martin furnace technology. Facing the characteristics of low calorific value and high water content of domestic waste in China, Sanfeng Environment insisted on problem-orientation and independent innovation. The Company broke foreign technology monopoly in business for 4 years and eventually realized the full set of domestic equipment optimization. At present, Sanfeng Environment has become one of the leading enterprises in the waste incineration power generation industry. By the end of 2021, Sanfeng Environment has invested 51 waste incineration power generation projects, with a daily domestic waste treatment capacity of 56,000 tons, leading domestic market share. Sanfeng Environment’s technology and equipment have been applied to 225 waste incineration power generation projects of China and 8 other countries, including United States, India, and Thailand.

Resource utilization of hazardous waste makes environment safer. In the field of industrial hazardous waste treatment, CITIC Environment starts from industrial upgrading promotion. With the goal of recycling, CITIC Environment continues to tackle core technologies and integrates a full set of incineration materialization and landfilling with independent intellectual property rights. Meanwhile, CITIC Environment successfully built Dongguan Haixinsha Hazardous Waste Disposal Project, China's first hazardous waste disposal project using rotary kiln incineration and plasma co-disposal process. The Project effectively solved the predicament of lacking safe landfill site for industrial hazardous waste disposal, and demonstrated the significance to promote transformation and upgrading of the hazardous waste market. By the end of 2021, CITIC Environment has laid out 7 high-quality hazardous waste disposal projects in Xinjiang, Shandong, Hainan, Jiangsu and other regions, with a designed annual treatment capacity of over 900,000 tons.
