Chemical Reductions

Innovative Measures

At our Norwalk Harbor, Dover and El Segundo facilities in Connecticut, Delaware and California, respectively, we pursued an innovative method to reduce the amount of chemicals required to treat discharged water. In these locations, we've implemented the use of an ultrasonic frequency, effectively controlling algae in wastewater and significantly reducing the amount of chemicals needed in the process.

At our Big Cajun II facility in Louisiana, we completed a project to remove chlorine gas used in controlling algae in the cooling towers located on site. The 16 one-ton cylinders of gaseous chlorine stored onsite were replaced with a safer salt brine system using electricity to produce bleach. The bleach solution produced is then pumped directly to the cooling towers and water pretreatment areas. Use of the bleach system at the cooling towers has reduced the risks and safety hazards associated with handling and storing large quantities of chlorine gas.
