CALIFORNIA, CA, UNITED STATES, October 19, 2026 /CourierPR/ -- Five Reputable Wastewater Treatment Equipment Manufacturers in China 2026: Advancing Environmental Solutions Exploring Technologies for Efficient Wastewater Treatment and Water Quality Management

China exported USD 2.38 billion in water filtering and purifying machinery under HS 842121 in 2024, according to the Observatory of Economic Complexity (OEC). This figure highlights China's role in the global water-treatment equipment supply chain, although the trade category does not represent the entire wastewater treatment equipment market.

Shandong Zhongqiao Enlightenment Environmental Protection Equipment Co., Ltd., established in 2013 and based in Weifang, Shandong Province, focuses on the research, development, and manufacture of integrated wastewater treatment equipment, dissolved air flotation units, lamella clarifiers, and customized water-treatment solutions. The company operates from a manufacturing facility covering approximately 40,000 square metres and employs around 170 people, with an engineering team of 15. Its annual output is approximately 900 sets. Shandong Zhongqiao exports to more than 30 countries and regions and has over 4,000 installations in China and overseas.

The company's product portfolio includes integrated sewage treatment equipment, MBR membrane systems, dissolved air flotation equipment, and lamella clarifiers. These products are relevant to domestic sewage, industrial wastewater, and decentralized treatment projects. The company lists the WSZ-100 model for applications including hotels, hospitals, camps, slaughterhouses, and livestock facilities. Its dissolved air flotation range includes the YW-5 model, with a stated rated capacity of 5 cubic metres per hour. The company also lists MBBR-related equipment, which uses biofilm carriers in a biological reactor and is suitable for selected domestic or industrial wastewater applications.

Shandong Zhongqiao's dissolved air flotation equipment is intended for wastewater containing oil, grease, and suspended solids. A Dissolved Air Flotation System introduces fine bubbles to help separate floatable contaminants, making it a potential option for a DAF Wastewater Treatment System in suitable food-processing, slaughterhouse, and other industrial applications. Its listed product range also includes a Lamella Clarifier, which supports solids separation through an inclined-plate settling arrangement. The company's equipment options include carbon steel, SS304 stainless steel, and polypropylene (PP), which can be assessed against wastewater composition, corrosion risks, installation conditions, and maintenance requirements.

The company states that it holds ISO 9001 certification and more than 100 patented technologies. Its reported product range provides a basis for evaluating integrated and customized equipment according to treatment capacity, materials, footprint, and wastewater characteristics. Buyers should request current certification documents, technical specifications, and relevant project references before proceeding to detailed technical assessment. Company-reported figures, product details, and project claims should be verified before publication or procurement.

CSCEC SCIMEE Sci. & Tech. Co., Ltd. operates in municipal water-environment management, industrial water treatment, and water reuse. Its publicly described activities include water-treatment technologies and engineering solutions for municipal and industrial applications, including sectors such as steel and coal.
