VB591® water Used for Bioremediation of Oil Spills
Industrial Plant, Florida

A Florida Industrial Plant receives hazardous wastes (including MTBE) and stores them in containers until they can be dumped into a controlled pond for remediation. The facility was building a 4,000,000-gallon lagoon to accommodate more waste and was looking for a way to process it faster and more completely. VB591® provided the plant with just the thing it needed.

During this sampling, VB591® stabilized pH levels and increased the microbial count from 2,500 cfu to 1.5 million cfu. In less than one month, oil and grease were reduced by nearly 70 percent and harmful contaminants including MTBE were degraded to below detectable limits.
