ABMet* for Selenium Removal. ABMet is a revolutionary biological process that removes metals and inorganics from wastewater to below non-detect levels. The ABMet process uses naturally occurring, non-pathogenic microbes to reduce and precipitate target compounds.
Selenium Removal Technologies A Review - Water …
BioteQ has its Selen-IX™ process for selenium removal.This system is unique in that a small volume of spent regenerant solution is directed to a selenium electrochemical reduction step, where iron is added to form an iron-selenium solid (as in iron co-precipitation).The selenium-free solution is recycled back to the IX circuit, which concentrates the selenium into a sludge and eliminates the ...

Selenium and nitrate removal from agricultural …
Mass removals of total soluble selenium of 77% or greater were achieved over a three-year period. Nitrate and selenate were removed by assimiliatory and dissimiliatory bacterial reduction, and nitrate was also removed by algal assimilation. The final removal of particulate selenium …
Removal of selenium from refinery wastewater - …
The stone properties of selenium however make its removal from solutions difficult and complex. Although insoluble when in its elemental state, selenium has four oxidation states (−2, +2, +4, and +6), which allows it to readily form a number of compounds that are highly soluble and therefore very hard to remove from solution.
Modeling of selenium and tellurium removal from …
01-03-2015 · This long removal time compares closely to the removal time of 23 h reported by Stewart et al. (1985) for a selenium removal at Vales ED plant in Sudbury, Canada. The impact of the saturated cuprous concentration on reaction times for selenium and tellurium removal at different initial selenium and tellurium concentrations is shown in Fig. 6.
