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. 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

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 mDepth 4,5 m (1m

Sedimentation

• Sedimentation Pool is part of Biologic Treatment
  to sedimentate Biologic Muds.Dimensions
  Diameter 17 mDepth 3,5 m (1m

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

Thickener

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

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 mSludge feed pump 3-13 m3/dWash
  water pump 12 m3/d
