AVK - Achieving zero discharge of harmful industrial circulating water
Our member company AVK Valves (Shanghai) has delivered a customised solution to match the various needs in different process sections for an extensive water treatment project in Beijing and Tianjin.Industrial circulating water affects the surrounding environment
In order to greet the XXIV Olympic Winter Games and improve the environmental quality around Beijing and Tianjin city, HBIS (one of the world’s largest steelmakers) decided to withdraw all its steel capacity from Zhangjiakou area, and implement the project of HBIS industry upgrade and Xuangang capacity transfer in Leting Economic Development Zone of Tangshan City, that required the supporting water system to achieve zero discharge of industrial circulating water. It is generally known that an industrial water project is characterised by a complex treatment process with high technology requirements. Throughout the entire water system project, the construction of the water treatment centre is a key point. It covers an area of more than 80,000 m2, with a treatment scale of 240,000 m3/h. The construction content includes the water supply system, the wastewater pre-treatment system, the desalination system, a concentrated brine treatment system and supporting facilities.
Nearly 200 AVK valves are delivered to this project including resilient seated and metal seated gate valves, double eccentric butterfly valves, eccentric butterfly valves and swing check valves, which are mainly used in wastewater regulating tanks, high efficiency sedimentation tanks, V-filter tanks, sludge dewatering rooms and comprehensive dosing rooms.
