Remediation Techniques

What is bio-remediation?

The process of Bio-remediation uses naturally occurring micro-organisms, which produce enzymes which break down oil into water and carbon dioxide. Although Bio-remediation is a commonly used technique, at Richfords we have made an inventive step in this field. The Richfords dosing machine automatically controls the environmental conditions for the micro-organisms ensuring optimum conditions.

These bacteria are used in two different ways. The first of these is in-situ remediation. In-situ remediation involves the introduction of the microorganisms, oxygen and nutrient solutions directly to
the area where the spill occurred. This method is used to reduce contamination in areas where contamination is moderate.

The second bioremediation technique is ex-situ remediation. This technique is used when contamination is moderate to severe. In this process the worst effected material is removed and transported to our treatment facility. The contaminated material is then placed into a bioreactor, where intensive bio-remediation is carried out. Upon successful completion of this process, the
material can often then be returned to site.
