This article is the seventh in a series on industrial water treatment focusing on inorganic contaminants; this one will discuss capital, operating, and lifecycle costs.
-
9/2/2016
This article is the sixth in a series on industrial water treatment focusing on inorganic contaminants; this one will discuss several emerging treatment technologies.

8/9/2016
This article is the fifth in a series on industrial water treatment focusing on inorganic contaminants. While regulatory limits are being established, the process of identifying a cost-effective treatment process should be undertaken. Potential water treatment processes for inorganic contaminants can be grouped into three categories: physical, chemical, and biological. This article will describe the biological treatment technologies that may be considered.

Selenium, a contaminant of concern in industries such as mining, oil refining, and power generation, is removed from wastewater principally through either biological or chemical/physical processes. This article will describe those technologies, several technology providers, and other sources of information.
