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 : 6.0-9.0 COD : 1000 mg/l BOD : 600 mg/l

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

Scheme of WWTP I : Inlet I with screen II : Inlet II with screen /Cikadu River I : Inlet I with screen II : Inlet II with screen a : Equalization I b : Equalization II c: : Neutralization d : Aeration Tank CMAS e : Sedimentation f : pH adjustment g : Coagulation h : Flocculation i : Post-sedimentation j : Thickener k : Belt Press Filter

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.

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

Equalization I

Equalization II

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

Aeration Pool (CMAS)

Scum in Aeration

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

Sedimentation Pool

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

Coagulation

Flocculation

Post-sedimentation

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

Thickener

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

Belt Press Filter
