Abstract:

This report on the sodium nitrite wastewater treatment process discusses the results of 12 simulation runs and six test runs using the boiler hydroblasting wastewater from the Long Beach Naval Shipyard LBNSY. Reproducible results were obtained showing the total destruction of sodium nitrite by sulfamic acid in Navy boiler hydroblasting wastewater. The removal of heavy metals was equally successful, an approach which resulted in reducing nearly all the ions to the discharge limits by EPA standards. The sludge contained 30 percent solids by weight and passed the TCLP test required for disposal. The estimated cost of treatment remains under 0.30 per gallon compared with the 1990 contract haul cost of 2.00 per gallon.
