Industrial Wastewater Treatment

Industrial Wastewater Treatment
The industrial wastewater contains a variety of impurities and therefore it requires a special solution. Water Siyuan Group provides high-performance customized water treatment solutions for any variety of wastewater types and industries. We help customers to achieve the industrial discharge limits that are constantly being tightened up. Closed loop and product recovery in various production processes are becoming an increasing priority among manufacturers.

We have rich experience in industrial wastewater treatment projects. Our accumulated expertise is advantageously employed for the technical and economic optimization of every subsequent facility. The wastewater treatment process may include physicochemical, biological (anaerobic and aerobic) and other steps.

In the case of biological (anaerobic) wastewater treatment process, we offer low and high rate reactors specially chosen for customers’ needs based on different applications. We are experienced in designing and building up many small-, medium-, large-scale plants on the basis of the world’s most frequently used UASB process. We also offer a high rate digester for medium organic strength wastewater that combines the two technologies together under an anaerobic environment, for example, the UASB and Anaerobic Filter. Our technological innovation is aimed at providing customers with the world most advanced solutions to help them fulfill their objectives, achieving the economy of investments, low operating cost, and space efficiency.

In the case of biological (aerobic) wastewater treatment process, in accordance with the characteristics of the wastewater, we offer the activated sludge process using fine bubble diffused aeration, aerators or jet aeration systems. In the case of high-end treatment requirements, we provide membrane processes with submerged or external membranes. The major advantages of this technology are considerable savings of liquid resources, savings of space, as well as effective recycling and zero discharge of wastewater.

Following technologies are used by the industrial wastewater treatment:
1. Anaerobic Biological Process
