System description




  • The plant has elevated unloading platform for trucks and tankers
  • Faecal sludge is emptied into a sludge receiving box of 1.5 m x 1.5 m
  • FS goes into an inlet channel which is 3m long
  • Screen bar is placed in the channel at an angle of 45°
  • From screens, influent goes to Setting-Thickening tanks of L x B x D = 14.5 m x 2.5 m x 2.55 m
  • Thickened sludge is taken out of S-T tanks after a period of 10 days and the supernatant goes into ABR chambers
  • Thickened Sludge is taken to sludge drying beds where they are kept till they are fully dried under direct sunlight
  • The supernatant is then kept in ABR for 2-3 days for anaerobic treatment
  • Effluent from ABR is then send to the horizontal planted/unplanted gravel filter
  • Water from gravel filters is then taken to polishing pond and finally the treated water is used within the plant premises for landscaping
