The Solvay process for soda ash production generates approximately 10 cubic meters of distillation waste liquid per ton of soda ash, making waste liquid treatment a common industry challenge. Leveraging multiple proprietary technologies (such as waste slurry cavity injection, waste slurry mixing, and comprehensive waste liquid treatment), we provide technical retrofit services for the integrated management of waste liquids and sludge to existing Solvay process soda ash enterprises.

We have completed waste liquid treatment retrofit projects of various scales domestically, including large-scale Solvay distillation waste liquid treatment projects with a capacity of one million tons. Depending on the owner's geological conditions, site constraints, and environmental requirements, we offer various technical solutions, including underground cavity injection, solid-liquid separation, and by-product recovery.
