8. Standard of Effluen of PT Lippo Cikarang
Standard of effluent from industry to be treated
At WWTP of Lippo Cikarang:
suspended solid : 200 mg/l
pH :
COD : 1000 mg/l
BOD : 600 mg/l

9. Treatment Processes First Stage (Equalization & neutralization)
Second Stage
(Aeration CMAS & sedimentation)
Third Stage
(Coagulation-flocculation, post-sedimentation)
Mud Treatment Stage
(Thickener & filter belt press)

11. Equalization Unit
To overcome shock loading in term of Quantity and quality.
Equalization I absorbs wasted water from clothing and food industries. Flow rate is 50 m3/hour and the Wasted Water are hold inside for 1.82 days.

12. Equalization II absorbs wasted waters from other sources
Equalization II absorbs wasted waters from other sources. And then mix together with wasted water from equalization I. Flow rate is 119 m3/hour and holding time 0,77 day. Dimensions : Length : 35 m Depth : 4,5 m (1m freeboard) Volume : 2187,5 m3

13. Equalization I

14. Equalization II

15. Aeration CMAS oxygenation
hydrodynamic purpose – wastewater mixing by air bubbles ensure regardful and intensive contact of micro-organisms with oxygen and purified water (organic pollution) Dimentions : Length : 76 m Width : 33 m Depth : 4,5 m (1m freeboard) Volume : 4838,75 m3

16. Aeration Pool (CMAS)

17. Scum in Aeration

18. Sedimentation
Sedimentation Pool is part of Biologic Treatment to sedimentate Biologic Muds. Dimensions : Diameter : 17 m Depth : 3,5 m (1m freeboard) Volume : 680,6 m3

19. Sedimentation Pool

20. Third Stage (coagulation-floculation and post-sedimentation)
Coagulation is process to separate Pollutant in suspended form or Coloid, by adding Coagulant.
Flocculation is process to form bigger floc by adding Floculant so that it can be easily sedimentated.
Post-sedimentation is process to sedimentate chemical mud resulted from Coagulation and Floculation process.
Chemical used:
Coagulant : alum
Floculant : polimer

21. Coagulation

22. Flocculation

23. Post-sedimentation

24. Thickener
Thickener Unit is used for thickening process of mud in Sedimentation Pool. Dimensions : Diameter : 12,5 m Depth : 3,5 m (1m freeboard) Volume : 368 m3

25. Thickener

26. Belt press filtering
Belt Press Filter is used for Mud Dewatering Process (decreasing water concentration) so that the muds can be easily and safely threw out in solid cake form. Dimensions : Length : 8 m Width : 6 m Sludge feed pump : 3-13 m3/d Wash water pump : 12 m3/d
