Treatment of Contaminated Aquifer
Because groundwater is susceptible to various types of contaminants, many of our aquifers have already been polluted. It is necessary to treat the contaminants before they reach active drinking water supply wells. Ex- situ bioremediation systems are the most effective solution to stopping contaminants such as nitrate, perchlorate, selenium, and organics from spreading.
By implementing our BBF system to the source of the contamination and separate points throughout the aquifer, the quality of the groundwater can ensured to meet Federal Maximum Contamination Level (MCL).

In-house testing OVerview
In July 2015, BKT Co. Ltd began testing the removal rate of nitrate and selenium using coal mining impacted water. Testing operations were monitored using BKT’s in-house pilot BBF unit.
• Evaluate the denitrification performance of the BBF system at different EBCT’s.
• Remove selenium as much as possible from the mining impacted water.
• Nitrate removal was consistent at all EBCT’s averaging around 97% removal.
• Selenium was observed to have a higher removal rate at higher EBCT’s, reaching 73% removal at 120 min. EBCT.
