Anaerobic biostimulation is a pollution treatment method that uses anaerobic microorganisms to degrade organic contaminants present in wastewater or contaminated soil. This method is often used to treat organic waste and petroleum products.
The anaerobic biostimulation process involves supplying nutrients such as carbon and nitrogen sources to anaerobic microorganisms to stimulate their metabolic activity. The microorganisms then use these nutrients to break down organic contaminants into methane gas, carbon dioxide and water.
The anaerobic biostimulation process can be carried out in a number of ways, including adding nutrients directly to the wastewater or using bioreactors to cultivate the microorganisms. This method can also be used in combination with other pollution treatment techniques, such as bioaugmentation (the addition of specific microorganisms to accelerate contaminant degradation) or biofiltration (the use of filtering materials to remove contaminants).
Anaerobic biostimulation is an effective and relatively inexpensive method for treating organic pollutants. It is often used in the wastewater treatment, bioenergy production and waste management industries.
For on-site remediation other treatment methods can be used, such as bioventing, composting, containment, thermal desorption, excavation, vacuum extraction, incineration, landfarming, chemical washing, chemical oxidation, phytomanagement, pyrolysis, chemical reduction, stabilization, stripping, biological treatment or granulometric sorting.
