Odor and hazardous gas treatment facilities
Removal apparatus of complex gas having variable type nozzle of mixing cleaning solutions and gas
Chemical cleaning method of deodorizing facility based on cleaning solutions and vortex mix by using high speed spray nozzle for fine dust and hazardous, foul odor gas generated in business premises such as sewage, feces, urine and sludge treatment facilities
  • Separate pre-treatment facility is not required by simultaneously treating fine dust and foul odor gas
  • Extremely high purification efficiency with single tower multi-level purification
  • Maintains stable treatment efficiency by consistently maintaining flow of high speed spray nozzle following change in air flow rate
  • Separate neutralization device is not required when treating waste solution
  • In case of high concentration odor, it can be treated with two-level chemical cleaning method based on Pall Ring layer
Field of application
Cement plant, metal processing plant, food plant, ceramic industry, rubber/chemical manufacturing plant, fiber/chemical plant, crop/feed plant, iron/steel, foundry, plant incinerator back-end equipment, dust for boiler, wood and milling plant, cement and stone smelting plant, pre-treatment of incinerator back-end equipment prevention facility, pre-treatment of big particle dust, dust removal in other industrial sites
It is called wet dust collector and it is a facility that removes hazardous gas and dust when hazardous gas and fine dust come in contact with liquid drop or liquid film.
  • Can treat more than 90% of water soluble dust and gas
  • Structure is simple and installation area is small regarding treatment gas
  • Lifespan of device and equipment can be extended when selecting corrosion-resistant material
  • Dust particles that are being removed are 1 micron so the efficiency regarding ultra-fine particles is relatively high
  • Continuous operation is possible and allows design and operation regarding wide scope concerning the size of dust, concentration and type of gas
Field of application
Dyeing plant, chemical plant, pharmaceutical company, coating plant (acid mist, alkali mist, fume), business site that emits fine particle substances, business site that emits fine particle suspended materials, wastewater treatment plant, business site that emits odor of human excreta treatment plant, business site that emits Volatile Organic Compound (VOC)
Deodorizing facility of Granular Activated Carbons
Device that removes through absorption and adsorption based on physical and chemical method when particulate matters such as organic gas, odor, etc. come in contact with surface of solid. By using the principle in which gas particulate matter comes in contact with surface of solid and sticks on it, selective removal can be made if constant absorbent is used even if the concentration of gas, liquid or solid is extremely low in the event such adsorption phenomenon is used so it is widely used.
  • Device is simple so it can be applied relatively comprehensively
  • Removal efficiency of low concentration gas is high but removal efficiency of high concentration gas is low
  • Installation cost is cheap and management is relatively convenient
  • Replacement of absorbent is required regularly.
  • Adsorption efficiency drops if the exhaust gas temperature (above 40℃) is high
  • No wastewater created.
  • Low pressure loss.

Deodorant injection type deodorization facility
  • Technology of decomposing and removing odor by spraying micro fog liquid drop containing deodorant in a space (duct or pipe)
  • System of spraying particles of size5~20㎛with high pressure pump and special nozzle
  • Water particles sprayed in ultra-fine aerosol instantaneously evaporates and cools immediately after being sprayed so it doesn’t become wet
  • Affordable installation cost and operation cost
  • Effective in removing high concentration odor
  • Stable efficiency even if the flow rate is high
  • Dust can be removed
Application place
  • Food recycling facility
  • Food waste treatment plant
  • Compost plant
  • Livestock farm
  • Landfill
  • Wastewater treatment plant
  • Human excreta treatment plant
  • Reduction of living odor
Regenerative Thermal Oxidation, RTO
Regenerative Thermal Oxidation (RTO) is the same process as a general incinerator that incinerates and processes VOC and organic foul odor gas at high temperature of about 650~980℃and it is an energy-saving equipment with highly efficient energy saving effect that recovers up to 95% of waste heat created after incineration and uses it to pre-heat process flue gas by using ceramic heat storing reagent instead of general Fin-Tube or Plate Type of heat exchangers.
  • Compact, Single Type integrated equipment
  • Capable of completely removing untreated gas produced upon damper conversion of existing method
  • Enables high energy recovery of above 95%
  • Applied to comprehensive VOCs and high decomposition efficiency (above 99%)
  • Affordable operation cost and long lifespan
  • Can be installed in small land area
  • Simple operation so separate workforce is not required
Field of application
Printing plant, petrochemical, semi-conductor, chemical, painting, food processing, wastewater treatment, VOCs and organic odor production facilities
Regenerative Catalytic Oxidizer (RCO)
  • With regard to RCO (Regenerative Catalytic Oxidizer) which is the representative combustion technology among VOC removal equipment, the previous thermal storage method has more than 2 regenerating chambers and shift replacement of gaseous flow takes place so the combustion chamber is located at the central part and the heat storing reagent made of metal or ceramic is used for filling
  • VOC and organic gas is oxidized at 200~400℃ by using heat storage reagent and catalyst then heat created during gas combustion
  • Compact, Single Type integrated equipment
  • Low fuel efficient, energy saving equipment
  • Stable, high treatment efficiency (above 99%)
  • Affordable installation cost and operation cost
  • Convenient operation and maintenance management
Field of application
Printing plant, petrochemical, semi-conductor, chemical, painting, food processing, wastewater treatment, VOCs and organic odor production facilities
