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

8
  • Wire Passivation

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

17
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

21
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
