What is a woodchip bioreactor?

Bioreactors are essentially subsurface trenches filled with a carbon source, mainly wood chips, through which water is allowed to flow just before leaving the drain to enter a surface water body. The carbon source in the trench serves as a substrate for bacteria that break down the nitrate through denitrification or other biochemical processes. Bioreactors provide many advantages:

• They use proven technology
• They require no modification of current practices
• No land needs to be taken out of production
• There is no decrease in drainage effectiveness
• They require little or no maintenance
• They last for up to 20 years.

How do bioreactors work? Organisms from the soil colonize the woodchips. Some of them break down the woodchips into smaller organic particles. Others “eat” the carbon produced by the woodchips, and “breathe” the nitrate from the water. Just as humans breathe in oxygen and breathe out carbon dioxide, these microorganisms breathe in nitrate and breathe out nitrogen gas, which exits the bioreactor into the atmosphere. Through this mechanism, nitrate is removed from the tile water before it can enter surface waters.

Remediation Terminology Definitions

Frequently used Soil and Water definitions ElectroHemp uses  when sharing the BioRad system and process which organically cleans Water and Soil in the Phyto-Enhanced system.

Phytoremediation is defined by UNEP as the living green plants for in sutu removal, degradtion, and containment in soils, surface waters, and groundwater.

Bioremediation is a process that uses mainly microorganisms, plants, or microbial or plant enzymes to detoxify contaminates in the soil and other environments.

Contamination is defined as any impairment of the quality of the water of the State by sewage or industrial waste to a degree which creates an actual hazard to public health thru poisoning or through the spread of infectious disease.

Heavy Metals are defined as the metals that have an atomic mass greater than 20 and are transition metals, metalloids, actinides, and lanthanides.

Toxicity is the ability of a substance to cause a living organism to undergo adverse effects upon exposure.

The science of phytoremediation

The study of heavy metal tolerance in plants in the late 1980s. The discovery of hyperaccumulator plants, which contain levels of heavy metals that would be highly toxic to other plants, prompted the idea of using certain plant species to extract metals from the soil and, in the process, clean up soil for other less tolerant plants.



Scientists also found that certain plants could degrade organic contaminants by absorbing them from the soil and metabolizing them into less harmful chemicals.

In addition to plants, microorganisms that live in the rhizosphere (the actively growing root zone of the soil) play a major role in degrading organic chemicals, often using these chemicals as a carbon source in their metabolism. In many cases, even the physical presence of a plant can improve the condition of the soil, giving it structure and stability and altering hydrology by enhancing water retention and preventing erosion.



There is no doubt that plants and the microbes associated with them can profoundly alter an ecosystem. Different types of phytoremediation have different potential results, such as accumulation of heavy metals in specific plant organs, voltilization from leaf surfaces, alteration of the form or availability of an organic chemical in the soil or within the plant, or actively excluding chemicals from plant tissues and keeping them out of the food chain.

The result depends on site-specific research and this approach is not generally appropriate for grossly contaminated soils that are an immediate ecological health risk. The major challenge to using phytoremediation effectively remains gaining an understanding of these various plant–chemical interactions and learning how to apply them safely in remediation programs
