Heat Optimized Technology (HOT) For Carbon Towers

Source: Evoqua Water Technologies

Increase Effectiveness and Simplify Sanitization While Reducing Water Consumption By Up to 75%.

Faced with an increasing need to maintain carbon and carbon towers in a sanitary condition, the food and beverage industry requires a consistent and, reliable ​sanitization method.  Heat optimized technology (HOT) helps address this need.

Carbon towers are very efficient in removing chlorine, chloramines, and a wide range of organic contaminants. Yet, they are vulnerable to bacterial growth and organic fouling, and therefore require backwashing and periodic sanitization. When fed with surface waters, they also require steam stripping to remove accumulated volatiles such as trihalomethanes (THMs).
 
HOT is a patented*​ process used for sanitizing carbon towers to control bacterial growth and organic fouling. By combining the carbon tower’s backwash and sanitizatio​n steps with a recirculation process in one cohesive step, this technology greatly increases the effectiveness of the sanitization, while reducing water consumption, and both simplifying and speeding up the process.

HOT Series systems can be provided independently, with or without an optional chilling exchanger, or as a complete system including carbon towers and ancillary equipment.​

Whether you require a new sanitizable Carbon Tower or want to convert existing towers to HOT operation, we can assist you with all your water, water reclaim/recycle, or wastewater treatment needs.​

Features ​Benefits​​
​Simple
  • ​One push of the button to initiate 
  • Automated for complete backwash and sanitization to exact requirements​
​Efficient & Sustainable
  • ​Sanitize while carbon is suspended by the backwash flow.  All surfaces exposed.
  • Saves 75% of backwash water
​Heat is applied while carbon is suspended during backwash.**
  • ​Allows for maximum exposure of carbon surfaces while carbon is suspended
  • Maximizes bacteria kill rate
  • ​Eliminates channeling and allows for uniform heating of the bed
​Flexible
  • ​System can operate single or multiple carbon towers
  • Run time can be extended at no extra consumption of water and with minimal energy usage
  • Can be fitted to use recirculating heat for sanitizing polishing filter housings and UV equipment
  • Can be fitted for immediate cooling allowing for immediate use of carbon towers​​
**  If the HOT skid is being connected to an existing carbon tower, the carbon tower design must be reviewed.​
