Paste Thickeners McLanahan

Paste Thickeners can help producers eliminate the need for settling ponds and other structures. They are meant to achieve the highest solids concentrations possible through gravity separation. The resulting mud, described as a paste, is often so thick that it becomes non-segregating — no further separation of water and solids can be achieved. As a guide, a paste material is measured with a ...

Paper: Transforming paste thickener technology

Abstract: Paste thickeners emerged as a technology in the mid 1990s, delivering previously unachievable underflow densities and associated handling properties. Paste underflows were achieved through self-compressive forces within the deep bed of the thickener. High sidewall paste thickeners, however, resulted in significant design difficulties and cost penalties.
