P&T system

Production wells are usually situated downgradient of the plume and injection wells upgradient.

.

Rates withdrawal and injection are the same, and the location of the production and injection wells is adjusted to encompass the entire plume. 

Contaminated water from the production well is piped to the treatment facility, processed, and piped to the injection well to be placed back in the aquifer.

Forager™ Sponge

The polymer can be placed in plastic columns in porous sponge form or in granular form as a stationary bed in a tank.  In either case contaminated ground water is piped in from the production well to the treatment facility, cycled through a series of columns filled with the Forager™ polymer and cycled back out of the treatment plant to an injection well. 

Chemical reaction kinetics determine the absorption efficiency of the polymers.  The reaction kinetics are influenced primarily by the flow rate of water through the columns or tanks and the water temperature.

Treatability tests should be conducted on the contaminated ground water to determine the optimum flow rate and temperature of the incoming contaminated ground water.

The optimum flow rate and water temperature are dependent upon the waste treated and the removal efficiencies required, as well as the number of treatment columns or beds employed.
