Case Study: Diesel Engine Block Final Rinse

SYSTEM: Automotive Remanufacturing
APPLICATION: Diesel Engine Block Final Rinse
PARTICULATE SEPARATED: Metal Fines, Fibers and Oil
PROCESS EQUIPMENT: Filter System with Oil/Water Separator on Immersion/Agitation Tanks

PROBLEM:
Remachined diesel engine blocks are immersed and agitated in an Aja Lif final rinse tank, requiring refreshment with water and chemical additive every 2 days - stopping product throughput while dumping and refilling the tank. Residual machining oil accumulates in the process water and must be removed to maintain product quality. This rinse tank was originally equipped with a sidestream bag filter system, incurring a high incremental cost in frequent bag replacement. Being a final rinse tank, high product quality throughput was absolutely imperative. Water/wastewater costs were high under this arrangement.

SOLUTION:
EFS installed the HydraKleen® Liquid/Solid Separator in sidestream on the immersion/agitation tank requiring dumping only every 30 days - not every 2 days. An oil/water separator integral to the HydraKleen® was added, removing oil from the process water. Moreover, they were able to completely abandon the conventional bag filter system and now incur no bag replacement expense or maintenance-related time. Product throughput is dramatically increased, while maintenance and water/wastewater costs are greatly reduced. Product quality is improved at a much lower cost.
