Five things you need to know about modern ‘passive’ bioreactors

Biochemical reactors (BCRs) have a longstanding history in the environmental field; however, they have only been recently employed as a tool in water treatment of the mining sector. As this field of technology continues to grow, bioreactors are gaining interest in the world of “passive” water treatment and the technology is modernizing at a rapid rate. These passive bioreactors are built into the ground and designed with the intention to require little operator intervention. There are more than a dozen names and acronyms in use to describe different bioreactors depending on the style or brand of system. The generic term “BCR” will be used here for simplicity, this includes types such as mixed-media reactors and gravel bed bioreactors (GBBRs). Here are five things that you should know about modern in-ground BCRs.
