Water rushing out of pulp and paper mill.


PARETO Mixing Technology for pulp and paper provides the optimal feeding solution of the interrelated and dependent variables of hydrodynamics, chemistry and water management to improve your pulp and paper processes. In addition to retention aid optimization, PARETO’s chemical mixing reduces costs, improves operational efficiencies and enhances finished product quality.

More Information

PARETO Mixing Technology is used for retention aid optimization and to improve the delivery of other process chemicals to the paper machine. This pulp and paper mixing technology focuses on the many variables that impact quality in modern papermaking, delivering optimization of key system inputs and improved machine efficiency. PARETO Mixing Technology can provide significant improvement in chemical efficacy while minimising the consumption of key resources such as water and energy.

PARETO employs innovative pulp and paper chemical mixing to deliver reduced fresh water consumption, reduced associated energy costs of fresh water heating, retention aid optimization, increased operational efficiency and improved quality control.

In seven years of operation, PARETO Mixing Technology offering has saved nearly 11 billion gallons of fresh water (~44 million m3) and nearly 46.4 MM Therms (1359 GW-Hr) of energy, meaning: 

  • ~ 100,000 American homes annual fresh water consumption
  • ~ 20 hrs. of Niagara Falls flow
  • ~ 800,000 barrels of crude oil
  • ~ 65,000 cars removed from the road
  • ~344,000 tons of CO2 prevented from release to the environment 

PARETO Mixing Technology is a patented, custom-engineered approach to feeding technology that uses pulp and paper injection mixing. Central to the technology offering is the PARETO Optimizer, whose design works in combination with custom CFD calculations and a unique understanding of chemistry to ensure that injection into the process stream is efficient and delivers retention aid optimization.

The integration of PARETO Mixing technology with our chemical programs begins with a preliminary system analysis and a comparison to alternative feed methodology. The delivery systems will then be engineered to your specific needs, aided by additional physical simulations that will ensure feed point and retention aid optimization. Combined with other novel Nalco technologies such as Core Shell, POSITEK 3G and ULTIMER, a PARETO programme delivers chemical mixing for pulp and paper that is profitable and sustainable.
