Some sludge bioremediation projects utilizing Biodyne's products and services. |
|
Heavy Equipment Washwater Pond Sludge |
| This project involved oily sludge in a washwater receiving pond from years of heavy equipment washing. The sludge depth was significant due to bottom consolidation caused by periodic filling in of the pond to gain more exhibit ground. The pond sludge resembled pudding and was >10' deep in some areas.. |
 |
| The microbes were grown on-site in "bug jugs" and stepped up using the two-drum biobreeder/biofeeder. The inoculum, mineral nutrients and surfactants were added to a 1000 gallon fiberglass tank. The mixture was pumped through an irrigation system to oscillating spray heads placed intermittently around the perimeter of the pond. |
|
| The sludge was mixed initially with a long reach track hoe by picking up the sludge and dropping it back onto the surface of the pond. When the sludge had thinned out slightly, bottom mixers/aerators were added to the pond to further facilitate reduction of the sludge. The project was completed in 15 months. |

Heavy Equipment Washwater Pond Sludge |
| This project involved oily sludge buildup on the bottom of a heavy equipment washwater receiving pond. The high TRPH sludge was as much as 1' thick in many areas of this 4'-6' deep pond. Although the pond hasn't been used as a washwater receiver for two years, the sludge remained. |
 |
| Microbes were grown on site and added to the pond on a weekly basis. Mineral nutrients and surfactants were also added to the pond as needed. Bottom aerators/mixers were placed into the pond to stir the sludge. The mixers were pulled back and forth across the bottom of the pond on a regular basis to loosen the sludge and put it into an aerobic mode so biodegradation could more easily take place. |
|
| Pond mixing and biological inoculation were performed for 12 months. At that time sludge thickness had been reduced to negligible amounts and TRPH concentrations had reached a point which satisfied environmental requirements. |

Heavy Equipment Washwater Pond Sludge |
| This project involved oily sludge buildup on the bottom of a heavy equipment washwater recycling pond. The high TRPH sludge was as much as 3' thick in many areas of this 6-8' deep pond. Most of the sludge was pumped to a temporary shallow treatment cell while the water was aerated. |
 |
| Microbes, mineral nutrients and surfactants were added to the water and sludge treatment cell. Bottom aerators/mixers were placed into the pond to stir the water and any remaining sludge. TRPH levels in the pond dropped to acceptable levels in 3 weeks while levels in the sludge treatment cell required 4 months. |
