Fast Creosote Bioremediation Results

Bioremediation of Waste Treated Wood

Fast creosote bioremediation was recently demonstrated by a user of a custom blend of CL Solutions organisms.  The environmental consulting firm applied the microbes to finely shredded wood that had been saturated with creosote.  The initial testing results after bioaugmentation showed a reduction of the creosote concentration by  57% in just 7 days.  The concentration measured as total recoverable hydrocarbons decreased from 3,453 mg/kg to 1,497 mg/kg.

Oil-Contaminated Water Treatment

Sustainable Bioremediation of Industrial Wastewater

CL Solutions provides a special consortium of microbes for oil-contaminated water treatment.   Under various conditions, the oil removal rate was as much as 1,300 mg/L/day.  In some situations the remediation goal is simply to remove the visible sheen or separate-phase oil.  With aeration, CL Solutions microbes were able to remove the visible oil layer and reduce the TPH concentration from 29% to less than 1% in 30 days at a waste oil lagoon.

Oil-Water Separator Discharge Improvement

Similar to waste water treatment in lagoons, Petrox is used to improve the performance of industrial and commercial oil-water separators by degrading dissolved-phase oil.  The treatment goal is to reduce the TPH concentration to below discharge limits to avoid fines, surcharges and potential discontinuation of service.  The Petrox organisms may be introduced into the collection and treatment system at any point,  but are usually added to the collection or equalization sump for longer contact time.  In most cases, the dissolved phase total petroleum hydrocarbons  (TPH) is reduced by 50% to 90% in a manner of days.

For example, at a large city municipal Petrox reduced the TPH discharge from 25.9 to 7.40 mg/L in three days.  At smaller retail oil-change centers the reduction was from 278 mg/L TPH to 14.1 mg/L TPH  in 21 days.  The biological treatment is maintained by adding a gallon of Petrox to the sump weekly.

The cost for maintaining discharge compliance at these applications is as little as $250 per month.

Benzo(a)pyrene Bioremediation Using Custom Blend Microbes

Benzo(a)pyrene is a difficult remediation challenge. It is resistant to biological and chemical destruction and extraction from soil.  CL Solutions Custom Blend microbes, however, have successfully remediated benzo(a)pyrene and other PAHs in soil during ex situ land farming treatment.  By placing the contaminated  material in windrows, controlling the temperature and moisture, the addition of Custom Blend microbes has reduced the benzo(a)pyrene concentration by as much as 330 ug/kg/day.

The same approach works on high as well as low concentrations.  At a site in Oregon, the benzo(a)pyrene concentration was reduced from 140 ug/Kg to below detection limits in 7 days.  At a site in Ohio, the benzo(a)pyrene concentration was reduced from 28,000 ug/kg to 3.8 ug/Kg in 60 days.  At both sites, Custom Blend microbes effectively treated the full suite of PAHs along with the benzo(a)pyrene.
