LOW CONDUCTIVITY WATER AND ION EXCHANGE RESIN WASTE PROCESS <br />FLOW DIAGRAM <br />The Iow conductivity water coolers at B291 use ion exchange resin to strip copper from the <br />water. The water is monitored for copper and when concentrations of copper are detected the <br />on exchange resin is exchanged, this occurs approximately every seven years. <br />Air is compressed and containerized at Be) <br />91 for various laboratory uses. Activated alumina <br />and carbon are used to remove moisture from the air during this process. Over time the <br />activated alumina and carbon desiccants become ineffective and must be exchanged; this <br />occurs about every 3 to 5 years, The spent desiccants are collected and disposed of as <br />hazardous waste. . <br />JUUKCE <br />Lrauri non or Measure <br />PREVENTION EVALUATION <br />LLNL plans to continue existing best management practices to minimize this <br />infrequent waste stream.
