  1. INTAKE GATE - RECEIVING THE WATER FOR INITIAL PROCESSING STAGE INTAKE GATE RECEIVES THE WATER FROM SOURCE (NAKDONG RIVER) AND SENDS WATER TO SAND FILTER BASIN
  2. SAND FILTER BASIN - SINKING THE SOIL, SAND, AND ALIEN SUBSTANCE TO THE BOTTOM OF THE BASIN, THE WATER IS FILTERED USING A BAND SCREEN, LIQUID CHLORINE IS ADDED FOR INITIAL STERILIZATION
  3. INTAKE PUMP - USING POWERFUL PUMPING FORCE THE WATER IS SEND TO THE PRE-OZONATION STAGE
  4. PRE OZONATION - THIS FACILITY OXIDIZES ORGANIC & INORGANIC SUBSTANCES, ELMNATING THM & ODORS, BACTERIA, VIRUS FOUND IN THE WATER SOURCE, AND LASTLY SUPPLYING OXYGEN FOR 2~6 MINUTES TO PURIFED WATER BY OZONE CONTACT.
  5. ARRIVAL BASIN BLENDING BASIN - THE FIRST PHASE OF OZONATION THAT EXECUTES VARIOUS TESTS ON THE WATER RESOURCE, THEN MIXES THE CHEMICAL COMPOUNDS PAC, PSO, SULFATE ALUMNUM AND GRANULAR ACTIVE CARBON, DISTRIBUTING THE QUANTITES EQUALLY THE WATER IS SEND TO THE SETTING BASIN STAGE.
  6. SETTING BASINS - SENDING HIGH GRADE WATER TO FILTER BED BY EXHAUSTING SLUDGE FROM COHESION & DEPOSITION
  7. FILTER BED - THE FILTRATION PROCESS IS ACTIVATED BY A FILM OF SAND (1.05M IN DIAMETER) AND GRAVEL ( 0.05M IN DIANETER). THE FILTERED SOURCE THEN GOES THROUGH OZONATION AND GRANULAR ACTIVE CARBON PROCEDURES. THE CHLEAN WATER FREE FROM ALIEN SUBSTANCES ON TO THE NEXT STAGE.
  8. PRO-OZONATIONTIN - THIS STAGE OXIDIZES SECONDARY ORGANIC & INORGANIC SUBSTANCES, ELIMINATING THM & ODOR AS WELL AS BACTERIA AND VIRUSES. LASTLY SUPPLYING OXYGEN FOR 2~6 MINUTES TO PURIFIED WATER BY OZONE CONTACT.
  9. GRANULAR ACTIVE CARBON FILTER BED - GRANULAR ACTIVE CARBON FILTER BED USES A .35M LEVEL OF ACTIVE CARBON FILTER TO ABSORB MICRO RESIDUES IN PURE WATER.
  10. GRANULAR ACTIVE CARBON FILTER BED - THIS IS THE LAST STAGE OF PURIFICATION, LOCATED ON AN UNDERGROUND LEVEL A SECOND CHLORINE STERILIZATION IS INITIATED. THE FINAL DRINKING TEST IS PREFORMD BY THE SANGSUDO STAFF MEMBER.
  11. PUMPING PLANT - CONVEYS THE WATER FROM TREATMENT PLANT TO THE RESERVOIRS.
  12. RESEVOIR AREA - RESERVES THE DRINKING WATER BEFORE IT SEND OUT TO INDIVIDUAL RESIDENCES.
  13. PRESSURING PWMPING PLANT - TO SUPPLY WATER TO HIGH LOCATIONS, THLS PUMPING PLANT IS POSITIONED OVER 40M ABOVE SEA LEVEL.
  14. HOME / OFFICE USAGE - CLEAN WARER IS DISTRIBUTED USING CONVENIENTLY LOCATED FAUCERS.
