Electrochemical Remediation of Wastewater

BR9501

Innovating Science™.

Water pollution is one of the largest threats facing the global population. Water is a finite resource. Once polluted, it cannot be set aside in the hopes that the environment will "make" new, clean water. One procedure often employed to treat wastewater is coagulation/flocculation. While the coagulation/flocculation procedure in wastewater treatment is effective, it involves the addition of chemical components to the water being treated. Recently, a great deal of attention has been given to less traditional alternatives to the typical process of coagulation/flocculation. One such approach receiving good deal of attention is a process called electrocoagulation. Electrocoagulation is a coagulation process carried out by an electrical charge.
