Hengshui Changhua Environmental Equipment Manufacturing Co., Ltd.( the former Ci-Ai-Yuan Sewage Treatment Aeration Plant in Taocheng District, Hengshui City) , located in the Small and Medium -Sized Enterprises Incubator of Binhu New District, Hengshui City, Hebei Province, specializes the production  of environmental equipment and accessories .

Among the serial products of our company, the sewage aeration is mainly produced, as well as various types of microporous aeration pipe, microporous aerator plate, high-efficiency polyamine aerator pipe, HDPE pipe and non-blocking chase gas spiral-flow aeration. Furthermore both of our microporous aerator pipe(membrane)and aeration disk(membrane) are elaborately made by high strength , high elasticity,high tear resistance, strong anti-aging high quality silicon rubber, EPDM and polyurethane, which are American, Germany and Netherlands in origin. As equipped with rubber mixing equipment, such as advanced channel rubber extrusion vulcanization production line,intelligent platen press, automatic injection molding machine, aeration pipe(disk) skeleton adopting high-strength, anti-aging high-quality ABS, reinforced polypropylene, UPVC and other engineering plastics production. We have the ability to produce strong and durable products, which are guaranteed by high precision rubber,plastic inspection instruments.

It is well known in the world rubber industry, that the technology of aeration film perforation and the selection of raw materials , are the key points. We, with the overseas, have the same perforating equipment and long-standing rubber processing technology. To our diaphragm hole, being smooth and no any gap at all, being weak of the resistance, it is not easy to be blocked, not easy for the sewage to reversely flow, over the aperture can be adjusted to the volume of the gas and the suspension of gas can be automatically closed. Benefiting from our high technology, we can produce quality goods of electricity saving and maintenance costs reducing.

All the silicone rubber aeration pipe(disk),EPDM pipe(disk),polyurethane aeration pipe and HDPE pipe produced by our company , can meet and exceed the standards of CJ/T3015.2-93.5(Exhaust Water Combustion

Performance Test) and HJ/T252-2006(Environmental Protection Products Technical Requirements Microporous Abuser) issued by the Ministry of Construction to the drainage equipment product quality supervision at the inspection center in the test of resistance loss,oxygenation ability,oxygen utilization rate,theoretical kinetic energy efficiency.They are fully alternative to the imported products and can save costs significantly.

We can produce various kind of diaphragm with different diameters or different lengths according to the customer's requirements. The size,quantity and number of holes in the aeration film also can be customized according to the user's requirements. Meanwhile we are dealing with the installation of oxygen tank aeration system maintenance.

We are willing to cooperate with customers at home and abroad with high quality products , affordable price and excellent service.
