The removal of the fine particles of glass in suspension in cooling waters having different solids content has been conducted by flocculation with two different additives, sedimentation and filtration. The process proposed allows the recycling of these waters; it may suggest a more efficient management and use of water in the glass industry. Among the different types of additives investigated, a particular type of polyacrylamide has shown the best results, both in the capacity of clarification and sedimentation of the fine suspended particles, and in the feasibility of the filtration process.

Abstract
The removal of the fine particles of glass in suspension in cooling waters having different solids content has been conducted by flocculation with two different additives, sedimentation and filtration. The process proposed allows the recycling of these waters; it may suggest a more efficient management and use of water in the glass industry. Among the different types of additives investigated, a particular type of polyacrylamide has shown the best results, both in the capacity of clarification and sedimentation of the fine suspended particles, and in the feasibility of the filtration process.File in questo prodotto:
