The successful convening of the meeting marks the formal start of another large demonstration project in the field of salty wastewater resource utilization in China, which will play an important role in promoting the business development of SUNPOWER Water Treatment Project.

The construction scale of Shenhua Yulin Coal Comprehensive Utilization Project (Phase I Project) is 1.8 million tons methanol /year. The project mainly includes process equipment, public industry and auxiliary facilities, out-of-plant projects, production management and administrative living facilities. The sewage treatment plant includes three sets of devices, covering biochemical treatment unit of salt-containing sewage, membrane desalination unit of salt-containing wastewater and crystallization unit of high salt water. The design scale of high salt crystallizer is 450 m3/h, which includes two parts: pretreatment unit and evaporative crystallization unit. The product water of the unit is reused in the circulating water system as supplementary water, and the high quality sodium sulfate and sodium chloride crystalline salts separated are utilized for resource utilization.
