Biological Deposit Control

• All Paper Production
• Chlorine for the incoming water
• Organic products for the stock systems
• Organic products for the additives

4
Retention Aids

• All Paper Production
• Generally polymeric agents to improve the
  retention of fiber and filler in the sheet.

5
Defoamers

• All Paper Production
• Defoamers and anti foamers
• Both have uses in Paper Production

6
Roll Treatment

• Recycled and Newsprint Production
• Mixture of surfactants, polymers and inorganic
  deposit control chemicals that maintain roll
  surfaces clean of stickies and pitch

7
Wire Passivators

• For all Paper production
• A mixture of cationic polymers with hydrophobic
  properties that is sprayed onto the forming
  fabric to prevent the permanent accumulation of
  stickies

Pitch Control

• Mostly Pulp production and Newsprint
• Mixtures of Polymers and dispersants that prevent
  the small pitch particles from accumulating and
  then fixing these small particles to the fiber

12
Stickie Control

• Recycled Paper Production
• Mixture of special surfactants and polymers that
  maintain stickies in a dispersed state and then
  affix these stickies to the surface of the fibers

13
Boil Out Programs

• For all Paper production
• Alkaline productions for most applications
• Acid Products for Carbonate scales
• Chelant mixtures for Barium scales

14
Felt Conditioning

• For all Paper production
• Batch cleaning and conditioning
• Generally alkaline based products with
  surfactants and solvents tailored to the
  contaminants

Felt Conditioning

• For all Paper production
• Continuous cleaning and conditioning
• Alkaline, neutral and acid products specially
  tailored for the PM and the contaminants

Yankee Coating and Release

• For Tissue production
• The coating sticks the sheet to the Yankee
• The release protects the Yankee from the
  continual pressure of the Creping Blade

Scale Control

• Geographically determined
• Chelant mixtures for simple systems
• Crystal modifiers for more complex systems and
  highly closed systems

22
Deinking Chemicals

• Recycled Printed Paper
• Products specially formulated for Washing systems
  and for Flotation Systems

23
Effluent Treatment

• All Paper Production (almost)
• Polymers for the removal of solids and color
• Odor removal chemicals

24
Process Water Clarification

• Recycled Paper
• Polymers and inorganic salts for SS removal so
  the water can be reused
