Primary treatment
Secondary treatment
Tertiary treatment
Primary and tertiary combined.
Lower capital/operation cost.
Complete destruction of contaminant
Possibility to remove reduced inorganics (e.g. sulphides/ammonia)
Can degrade metals.
All of the above are advantages of bioremediation processes.
