Circular mine thickeners, access bridges and return-water basins, used as an industry or equipment reference. Process selection depends on water quality and project conditions.
Your process challenges
Chemistry matched to real operating conditions.
Improve the basis for slurry-treatment selection by connecting particle behavior, separation equipment and return-water needs.
Treatment approach
Aggregate & Sand-Washing Water: understand the treatment stages first.
Compare flocculation, settling, thickening and filter pressing according to fine-particle and clay content in aggregate-washing slurry. Consider return-water turbidity and filter-cake management.
Check together during selection
Compare settling, filter pressing and scaling risks using representative slurry and return water, with equipment and reuse conditions taken into account.
Compare candidate products below by treatment objective. Evaluate different routes separately; the list does not imply simultaneous dosing.
Aggregate & Sand-Washing Water: match requirements to each treatment stage.
Compare treatment objectives, chemical functions and verification criteria stage by stage. Products in the table may be alternatives or serve different stages; they are not necessarily dosed together.
Define influent and objectives first
Share aggregate mineral composition, mud content, return-water targets, tanks and dewatering equipment. This helps organize selection around settling, dewatering and return-water requirements and narrow the product and specification range.
Then confirm assessment limits
Use representative mineral slurry and return water to compare settling, filter-press performance and scaling risk against equipment and reuse conditions.
