Case Study: Immersion / Agitation Tank Case Study

Immersion/Agitation Tank
SYSTEM: Automotive Remanufacturing
APPLICATION: Gas & Diesel Engine Block Rinse Tanks
PARTICULATE SEPARATED: Gasket Material, Casting Sand and Rust
PROCESS EQUIPMENT: Filter System on Immersion/Agitation Tanks

PROBLEM:
After leaving a molten salt cleaning system, engine blocks are immersed and agitated in process rinse tanks to remove gasket material, casting sand and rust. To maintain product quality, water and chemical additive were dumped and refreshed every 2 days resulting in high water/wastewater costs. Moreover, product throughput went to zero while dumping and refreshing the process rinse tanks.

SOLUTION:
EFS installed the HydraKleen^® Liquid-Solid Separator in sidestream on four Aja Lif immersion/agitation tanks, removing the gasket material, casting sand and rust, turning bi-daily dumps into bi-weekly dumps. HydraKleen^® increased product throughput significantly, while greatly reducing maintenance and water/wastewater costs. Product quality is now greatly improved at a much lower cost.
