Air Group personnel recently completed upgrades and repairs to a competitor's problematic RTO system at a municipal sludge dryer and pelletizing plant in California.

Issue

  • Existing two chamber RTO not meeting California emission standards
  • Ceramic saddle media plugging in 2-3 weeks with particulates and silicone compounds
  • Owner spending $40,000/month to continually replace media
  • System downtime causing major loss of revenue

Solution

  • Upgraded RTO with Colt's hybrid media beds, replacing poor performing saddles
  • Upgraded RTO with instrumentation to monitor individual heat recovery beds
  • Modified RTO to allow washout of the new hybrid media

Results

  • Colt's upgraded RTO ran 9 months before first washout, with total downtime reduced to 6 hours
  • Additional instrumentation allowed more efficient operation of RTO reducing operating cost
  • Plant met production goals for the first time since original RTO startup
