1.Project Brief
The paper mill used reverse osmosis technology to purify the river water, and the RO permeate water is used for production. The treatment capacity reaches 235,000 tons per day, and there are 32 plants of RO system in total. .In 2019, 336 BW-8040FR elements from KeenSen were purchased to be used in one of the systems. So far, the membrane system is working stable.
2.Technological Process
River water—Sedimentation—Neutralization detonation—Sedimentation—Mesh flocculation— Strong endorphin sand filter—Self-cleaning filter—RO
