sodium sulfate. This Mould increase the sodium sulfate concentration at Pig's <br /> Eye by about 0.6 mg/1. It should be noted (and is noted in the attached memo) <br /> that the 390,000 lb/yr .of sodium sulfate discharged by the CRF is about one <br /> third of what would be discharged if the individual shops installed their own <br /> pretreatment systems. <br /> .Regarding the `solid' wastes processed and produced by the CRF it is; of course, <br /> worth noting that metals will be recovered as part of this operation. This will <br /> reduce the burden on both Pig's Eye and hazardous waste land disposal sites. <br /> The following table shows the estimated amounts of metal recovered and disposed <br /> by the CRF in pounds per year: <br /> lb/yr <br /> 1. Total metals recovered 86,000 <br /> 2. Metals processed but not 29,000 <br /> recovered (to land disposal <br /> or to Pig's Eye) ✓ <br /> 3. Metals in sludges processed 101,000 <br /> or handled (to land disposal ) <br /> 4. Total metals disposed, sum 136,000 <br /> of 2 and 3 <br /> S. Total disposed as hydroxides, 217,000 <br /> dry weight <br /> 6. Total disposed as sludge, 25 866,000 <br /> percent solids <br /> The estimated pounds per year of each metal recovered-are- shown in the following <br /> table: - - <br /> Cadmium 1,600 <br /> Chromium 16,900 <br /> Copper 12,200 <br /> Nickel 13,000 <br /> Zinc 42,720 <br /> TOTAL 86,400 <br />
