Thickening and Clarification systems

ANDRITZ thickening and clarification solutions are designed to achieve the highest production rates without compromising efficiency. For all counter-current decantation (CCD) plants, the new and improved ANDRITZ inter-stage mixing and dilution system for CCD circuits helps to reduce the footprint and consequently cut CAPEX while maintaining low operating costs. The innovative paste-thickener design facilitates highly clarified liquid recovery as well as maximum underflow densities.
