In May of 2018, an eastern power utility encountered an urgent need for a selenium removal system during the closure of one of their ash ponds. Frontier deployed a SeHAW® Mobile bioreactor which was deployed to site within 30 days of the order. While operational, the bioreactor experienced temperatures in the treatment stream as low as 35o F , and the system continued to reduce selenium below the required limits. Working in conjunction with an upstream absorbent media system, the system demonstrated compliance that could not have been met without the additional biological treatment.
