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 Unit

12

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.

Equalization II

Aeration CMAS

15

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 mDepth : 4,5 m (1m freeboard)Volume : 4838,75 m3

Aeration Pool (CMAS)

17

Scum in Aeration

Sedimentation

18

Sedimentation Pool is part of Biologic Treatment to sedimentate Biologic Muds.

Dimensions :Diameter : 17 mDepth : 3,5 m (1m freeboard)Volume : 680,6 m3

Third Stage(coagulation-floculation and post-sedimentation)

1. Coagulation is process to separate Pollutant in suspended form or Coloid, by adding Coagulant.

2. Flocculation is process to form bigger floc by adding Floculant so that it can be easily sedimentated.

3. Post-sedimentation is process to sedimentate chemical mud resulted from Coagulation and Floculation process.

Chemical used:Coagulant : alumFloculant : polimer

Thickener

24

Thickener Unit is used for thickening process of mud in Sedimentation Pool.

Dimensions :Diameter : 12,5 mDepth : 3,5 m (1m freeboard)Volume : 368 m3

Thickener

Belt press filtering

26

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.
