Bioremediation Examples – Hydrocarbon Wastewater

Bioremediation Examples

This post is a bioremediation examples using Custom HC, a bioremediation product, to reduce petroleum in wastewater.

Bioremediation is the use of microbes to detoxify contaminants in the environment, usually in the soil or in the water.

Custom HC – Bioremediation Product

Custom HC is a bioremediation product, manufacture by Custom Biologicals. Custom HC contains billions of beneficial bacteria. These bacteria have been specifically selected because of their enhanced ability to degrade petroleum and refined petroleum products.

Case Study Details – Physical Plant

This case involves a wastewater treatment plant that processed 1 million gallon of water per day.

The plant consisted of four 500,000 gallon clarifiers, a two stage 40,000 gallon flocculation/aeration collection tank and a 2,000,000 gallon lagoon. Retention time is 4-7 days.

The Problem – Petroleum Over Limits

County surcharges for excess COD and TSS amount to an average $450,000/year. VOC’s are offensive to adjacent neighbors. The use of polymers injected at the headworks was not sufficient to reduce the petroleum.

Treatment Plan

Initial Treatment – Three – 55 gallon drums of Custom HC

Week One – 22 GPD (Gallons per Day) of Custom HC
Next Weeks – 6 GPD of Custom HC

Bioremediation Examples – Results

The results of this bioremediation project were outstanding and the full results are below. The treatment resulted in a reduction of costs of other $30,000.00 per month. All of the compounds that were sampled for showed major reductions.

Bioremediation reduced COD (Chemical Oxygen Demand), BTEX (Benzene, Toluene, EthylBenzene.
