McLanahan EcoCycle

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 Yield Stress of >150 Pa. Pastes are then moved to impoundment structures via positive displacement pumps.

Because of the high percentage of solids in the resulting space, producers can greatly reduce, and sometimes eliminate, impoundment size, structure and volume. They are also able to eliminate freestanding water or ponds. Not only does this create a safer working environment, it also helps with permitting and regulatory requirements.

Features:

  • Produces highest solids concentration of sludges achievable by gravity thickening alone
  • Maximum water recovery
  • Underflows often paste consistency, meaning there is no further separation of free water
  • Rotating pickets provide pathways to release water from sludge and allow for further compaction
  • Paste sludges require less infrastructure for impoundments
