Major Technology.

This is a process that uses water flow of the mono-reactant that has aligned aerobic zone, organic matter, nitrogen, and phosphorus vertically to remove sewage biologically through non-powered internal return. Also, it is a process that installs hollow fiber membrane within the aerobic tank for solid-liquid seperation and coliform group treatment.



PROCESS FEATURE

Category Feature
Advanced sewage treatment process
using separation membrane(DMBR)
  • Stability in processing changes in load
  • Secure high infiltration speed
  • Minimize required sites and sludge generation

This is a process that has added sludge denitrification, anaerobic, and anoxic conditions to previous conventional activated sludge method in order to use the characteristics of microbe and to process nitrogen and phosphorus biologically at the same time. By internally applying denitrification to nitrate nitrogen contained in return sludge on the sludge nitrification tank, it can remove phosophorus effectively.



PROCESS FEATURE

Category Feature
Sewage treatment process(DNR)
  • Similar to conventional activated sludge method
  • Effective treatment in low water temperature
  • Minimize facility, operation and maintenance cost

This is a state-of-the-art water purification process that has added membrane contamination index anticipation model and pre-processing automatic control process to the treatment process composed of mixing, collection, settlement, and membrane filtering. It can remove 99.99% of chlorine resistanti pathogenic microbes and has improved ease of operation through automation of the entire process.



PROCESS FEATURE

Category Feature
Automatic membrane seperation water purification(DIMS)
  • Secure stable water quality in high turbidity and high flow
  • Reduce consumption of coagulant compared to existing processes
  • Reduce power consumption compared to other pressurized membrane filtering technology
  • Minimize maintenance point for each process

This is a 2-phase anaerobic digestion process that operates acid fungus and methane fungus having different growth conditions in optimal condition respectively, deals with high density organic waste resource, and produces methane. It is an organic waste resource energy technology that produces buffer and organic acid in acid fungus tank and produces high purity biogas from organic acid in methane fungus tank.



PROCESS FEATURE

Category Feature
Renewable bio energy manufacturing process(DBS)
  • Can be finished in short time with wet type/dry type parallel digestion(HRT < 10day)
  • Can flexibly respond to load change in waste

This is a 2-phase anaerobic digestion process that can process a variety of high concentration organic matters, easily remove internal sediments and scums compared to existing processes. It has applied circular type digestion tank and improved UASB has improved high purity biogas production rate and content of hyper methane with short residence time.



PROCESS FEATURE

Category Feature
Improved bio energy manufacturing process
(improved DBS)
  • Energy efficiency is high due to high biogas generation and methane content
  • Remove factors that interfere with anaerobic digestion
