    Project Simplicity
  • The Fenix™ is contained, compact, and complete. You don't have to design electrical systems, air handling runs, motor controls, or anything else.
  • Minimal connection points to the plant required (single connections for electrical, fuel, water supply, water drain, flue exhaust, and modem line).
  • Fenton can handle installation, certification, and upstream/downstream conveyors.
  • Permitting needs for the Fenix™ are modest, and Fenton will help obtain approvals. The units rarely need air permits, the thermal units are FMRI and ASME rated, and the biosolids exceed EPA time and temperature benchmarks for Class A biosolids.

    Operation Flexibility
  • System handles variable input sludge moisture characteristics and feed rates.
  • System allows flexible scheduling for efficient operation on single shift, double shift or around the clock runtimes.
  • System allows easy adjustment of biosolids moisture levels.
  • The machine can use various fuels on single or dual fuel burners. Users can choose either a motor or a hydraulic drive system.
Low leak seal for Fenix sludge dehydration chamber.
    System Reliability
  • The batch design with low RPM disks and product augers, along with the use of thermal fluid, means less strain and wear on parts.
  • In the dehydration chamber, the continuous mixing action coupled with three end-cycle sensors ensures reliably consistent biosolids.
  • Low-leak seals, auto-lube greasers, and other maintenance features help operators keep the machine running smoothly.
  • There are no parts that are expected to fail or wear out. The rare mechanical problems have historically been minor and easy to resolve.

    Safety Features
  • The Fenix™ design is inherently safe with slow movement, contained dehydration and airflow, and a low-pressure heating fluid system.
  • Fire risk is prevented by keeping biosolids below self-ignition temperature, isolating external combustion sources, steam purging dust and gases before discharge, and preventing chamber opening if sensors detect that the product is too hot.
  • Sub-system monitoring is integrated into the central control panel and the system as a whole will be stopped if the air, oil, or water flow is interrupted or incorrect.
