SpillRemed (Industrial) for industrial Oil Water Separators
Sump receiving the wash water from the shop
The water after washing the inside of the port vehicles is first stored into the sump before releasing through the oil water separator and an operator is seen collecting a water sample before treating the watere in the sump with SpillRemed (Industrial) as seen in this photograph.

The process of bioremediation of oil received from the wash water is to first disperse the oil into smaller droplets for the microscopic bacteria to consume. The photograph shows breakdown of oil immediately after addition of SpillRemed (Industrial)

Once the oil is broken down into smaller droplets, bacteria consume the oil. TPH of the oil in the wash water on the day of treatment was 286 ppm with a large population of bacteria along with the oil droplets. However, on 7th day another sample was collected and interestingly this was water was very clear. Under microscope, the population of bacteria was much less than on the start day and the TPH of the water was 25.6 ppm thus suggesting that once the oil is consumed, bacteria die a natural death. One more significant observation was that there was a sudden increase in protozoan population in this water and this was attributed to the reduced toxicity of the water in the sump. These protozoans were transferred into a culture medium to facilitate the growth of the population and in one set the protozoan were fed with SpillRemed and one could see that the population of these ciliates was actually feeding on the bacteria and thus in a water which did not allow healthy growth of protozoans, there was now an establishment of a food chain.The results answered an important question of what happens to the bacteria after the oil is consumed; they either die a natural death in the absence of any available food or predators consume these bacteria.
Oil Water Separator showing absorbent pads
The wash water after cleaning port vehicles under 2000 psi contains oil and grime that passes through the oil water separator that absorbs free oil and facilitate discharge of water free from oil into the waste water stream. However, there have been incidents where the local municipality cautioned thte corporation of discharge of oil.
