To confirm that an existing thickener is appropriately sized and configured for both current and future operating requirements, MINEXXT conducts reagent screening, static settling, and dynamic thickening test work using fresh, representative samples collected on-site during the assessment. The same principles apply when sizing new thickeners for greenfield projects, ensuring the selected equipment is appropriately designed to meet the required duty and performance criteria.
The test work establishes key design and operating parameters, including the optimum flocculant and coagulant types and dosages, optimum feed solids concentration, achievable underflow density, and overflow clarity. These results provide critical input for assessing existing thickener performance and form the basis for the design of new thickeners, as well as any recommended upgrades or retrofit solutions for existing installations.
