• CALL FOULING
• MAJOR FOULING MECHANISM CONSIST OF
• - PRECIPITATION FOULING ( SCALING )
• - BIOLOGICAL FOULING ( SLIME )
• - CORROSION FOULING
• - PARTICULATE FOULING ( SEDIMENTATION )

FOULING RESISTANCE VS. TIME Water condition -
450 ppm Caco3 / 95 deg.f., - Velocity 5 ft /
sec. Result - Constant fouling resistance(
0.001 )/ 900 hrs. Additional chemical to water
- 2,000 ppm Caco3 / 110 deg f. - Velocity 5
ft / sec. Result - Quickly fouling resistance
increase ( 0.006 )/ 100 hrs
