SEQUESTRATION

Isolate contaminants; avoid their distribution and withdrawal by suction into water off-takes

• Natural Processes
  • In storage, separation and sequestration of heavy metals, chemicals, soil particles, and organic matter naturally occurs through adsorption, flocculation, precipitation, and settling, then incorporation into biofilms and sediment

• Active Processes
  • Avoid re-suspending sediments by using calming inlets to tanks
  • Position outlet at least 4 inches (10 cm) above bottom of tank
  • Position smart outlets and use floating collared offtakes to draw outlet water from the cleanest strata of the tank, several inches below the top of the water level
