Water from the maintenance shop in South Jersey Port Corporation in New Jersey was contaminated with free oil and grime during pressure washing of port vehicles. The shop would wash at least four vehicles in a day. Wash water was released through an oil water separator system using absorbent socks and diapers to absorb the oil before release into the waste stream as per the directive of the local waste water treatment facility. The TPH of the water received from the washing of vehicles in the South Jersey Port was pre-treated with SpillRemed and in one week there was more than 90% reduction in the oil content and the water was clear as can be seen from the testimonial from the corporation. Pre-treatment of sump water before passing through OWS reduced load on the existing system and also prevented discharge of oil in the waste stream. Interestingly, the study showed that toxic effect of the hydrocarbon was reduced by SpillRemed as evidenced by sudden growth of protozoans. In the laboratory it was noted that these protozoans fed on the bacteria in SpillRemed indicating the beginning of a food chain in a system that did not support any life earlier.
