Colt has completed multiple Biosolids dryer projects, achieving unmatched performance and reliability. In order to handle this very demanding application, Colt engineers started with a clean sheet of paper, and designed the RTO with features that address the problems plaguing the dryer industry.
Colt's Dallas based Air Quality Control Group received an order for a 3 chamber MAXIM™ RTO system to control the Volatile Organic Compound (VOC) and Hazardous Air Pollutant (HAP) emissions from a municipal sludge dryer.
This order followed the year long repair and maintenance of a competitor's 2 chamber RTO which had been causing outages monthly since its startup.
- Corrosion of components from Hydrogen Sulfide
- Plugging of Heat Recovery Beds with organic particulates in the dryer exhaust
- Siloxane converting to Silica Dioxide in beds and causing premature bed failure
- Hazardous Air Pollutants requiring very high destruction performance (99%+)
- Effective means of washing out the beds
- Very high reliability required with long runs between scheduled outages for service
- Design RTO Heat Recovery Beds for easy, effective washout
- Provide custom designed heat recovery media
- Allow easy collection of wash water
- Strategic use of corrosion resistant alloys and composite materials
- MAXIM RTO has 12 months of uninterrupted operation since startup
- Easily met all California emission standards
