Efficacy Of Electrocoagulation Technology On Selenium-Contaminated Mine Effluent
Efficacy Of Electrocoagulation Technology On Selenium-Contaminated Mine Effluent

This paper helps to understand the efficacy of BakerCorp Electrocoagulation (EC) technology and treatment process in treating selenium-contaminated mine effluent. Two mine effluent samples were treated by baker EC. Selenium constituent concentrations in both water samples were reduced significantly to below reporting qualification limits. Based on the results of the effluent samples, electrocoagulation is an effective treatment option for waste streams found to contain selenium.

    Total Kjeldahl Nitrogen: Simplified With s-TKN™

    The Dallas County Water and Sewer Authority (DCWSA) in Selma, Alabama recently found itself in a tough spot: under the scrutiny of the Alabama Department of Environmental Management (ADEM). The wastewater treatment system needed better means for control. Ammonia, TSS, cBOD, and TKN readings were out of compliance. Then they discovered a new testing method known as simplified-TKN (s-TKN), and with it, better process control to achieve regulatory compliance.
