Tanks
Tanks or Basins are constructed of such material as steel, concrete, wood, compacted earth,
plastic sheeting, and soil cement. The selection of the materials of construction is based on cost,
availability, topography, water table, ground condition, climate, operating temperature and
chemical corrosion resistance. Typically, industrial tanks up to 30m in diameter are made of steel.
Drive Support Structure
Bridge supported thickeners are common in diameters of 30m, the maximum being 45m. They
offer the following advantages over other thickeners:
Ability to transfer loads to the tank periphery;
• Ability to give a denser and more consistent underflow concentration with a single draw off
point;
• A less complicated lifting device;
• Fewer structure members subject to mud accumulation;
• Access to the drive from both ends of the bridge; and
• Lower cost for units smaller than 30m in diameters.
