IFM recently assisted a large tire and rubber manufacturer with issues associated with years of corrosion occurring in facilities’ cooling tower system.
Due to the corrosion in the cooling tower, copper and zinc was being released in the blowdown water which was received by the local POTW. The levels of copper and zinc discharged to the POTW were in violation with the local pretreatment limits. To help the client overcome these violations, IFM designed and built a 4 gpm skid mounted system with triple 10x54 vessels, each holding 2 cubic foot capacity SIR 300 resin. The skid design also included a mounted pump, pre-filtration and a water meter.
SIR 300 is a chelating resin with a pre-disposition for heavy metals, ignoring background TDS (high concentrations of calcium, hardness and chlorides). The permanent system was built according to a successfully run pilot system that proved the effectiveness of ion exchange earlier in 2010.
