HEAT PUMP TYPE SLUDGE AIR DRYER(Sepa Dryer – HPSD)
It is a eco-friendly water treatment dryer which uses dehumidified air circulation for recycle energy(enthalpy)in air.
It is energy-saving model of sludge air dryer with a heat pump type waste heat recovery device which cools down, condenses and re-heats humid air for uniform inflow air temperature in system.

*Energy consumption for moisture reduction 0.6kwh/1kg.water

FEATURE
  • Air pollution prevention system is unnecessary
  • Semi-permanent refrigerant
  • Dehumidified air circulation
  • Higher energy efficiency than basic model
  • Economical operating cost
  • Reduce CO₂ emissions
DRYING PERFORMANCE
APPLICATION
  • Wastewater treatment plant, food waste disposal plant
  • Night soil treatment plant, animal manure treatment plant
  • Food factory, meat factory, animal feed factory
  • Paper manufactory, chemical plant
  • Applicable to all of rear dewatering process
    (Centrifugal hydroextractor, belt press, filter press, screw press& etc.)
Case Study
  • Case-1. Kolon Industry Co.,Ltd.(Gumi Factory – Chemical Fiber Factory)
  • Kolon Industy Co.,Ltd is the biggest chemical-fiber manufacturer and main factory is located at Gumi-city in Gyeongbuk province.
  • They have an wastewater treatment plant in their area which is available to treat throughout up to 3,000 m3/day and consisted of chemical and biological process.
  • Regarding to sludge treatment, originally they treated wastewater and dewatered sludge as 15% dry solid but they worried about final treatment for high water content of their sludge.
  • So their manager had selected our sludge air drying technology because it removed water environmentally friendly by use of air blowering and cyclone drying.
  • Reentec’s dryer had installed at Gumi-factory on 28th February 2011 and have performed successful running until now.
  • [Inlet dry solid was 15% and outlet dry solid was discharged of 40% after drying.]
  • Case-2. Kolon Industry Co.,Ltd (Gyeongsan Factory – Chemical Fiber Factory)
  • Kolon Industry Co.,Ltd was impessed with Reentec’s sludge air dryer and evaluated its operation for one year and more.
  • And then they had purchased a new dryer one more and installed it at their Gyeongsan factory on 20th October 2012.
  • [Inlet dry solid was 19% and outlet dry solid was 45% after drying.]
  • [Feed sludge capacity : 750kg/hr, 18ton per day]
  • Case-3. Jeoneup City (Jeoneup Sewage Treatment Plant)
  • Jeongeup sewage treatment plant is located at Jeongeup city in Jeonbuk province.
  • Their treatment throughout was 90,000 m3/day and they had performed activated biological sludge treatment process.
  • They had dewatered sludge cake with water content 83% before their sewage sludge treatment plant was constructed.
  • However they had planned and completed a sludge treatment plant on August 2012 as 40ton/day of sludge feed capacity.
  • Now they have operated Reentec’s sludge air dryer for 24hours per day and confirmed for as to assure the drying performance about municipal sewage sludge.
  • [Inlet dry solid : 17%, outlet dry solid : 45%]
  • Case-4. Dong Suh Food Co.,Ltd. (Changwon Factory – Coffee Factory)
  • Dong Suh Food Co.,Ltd is the best and the biggest coffee maker in Korea and located at Changwon-city of southern area.
  • They have a 3,500 m3/day of wastewater treatment plant in their factory.
  • Their manager had decided of Reentec’s sludge air dryer in order to reduce moisture content of their dewatered sludge cake(max. 18%ds)
  • He planned the dried sludge 50%ds to burn it into their incinerator of Changwon factory for final disposal.
  • It was possible as the dried sludge had good heating value higher than 6,000 kcal/kg.
  • [Inlet dry solid : 18%, Feed capacity : 20 ton per day, Outlet dry solid : 50%ds]
  • Case-5. Toray Advanced Material, Korea (Gunsan Factory-Chemical Material Factory)
  • Toray Advanced Material, Korea(TAK) is an special chemistry factory invested 100% by Toray Group of Japan and located at Gunsan-city.
  • They had selected Reentec’s cake dryer instead of conventional Japanese dryer because of good performance and easy operation.
  • Feed capacity of dewatered cake was 10ton per day. And inlet moisture content was 78%(20% ds).
