Technologies & Services for the Treatment of Water, Liquor and Chemical Recovery Cycles for the Pulp & Paper Industry

Understanding the Challenges Facing Pulp & Paper Companies

Water is vital to the production process at Pulp and Paper facilities. Veolia Water Technologies understands the issues related to water and wastewater management and has experience in helping manufacturers achieve their goals in:

  • Regulatory Compliance 
  • Operational Efficiency
  • Increased Resource Recovery
  • Risk Mitigation
  • Corporate Sustainability Initiatives

A Creative and Trusted Solutions Provider

Veolia Water Technologies is trusted by leading Pulp and Paper companies since the 1960s, and has successfully completed hundreds of water, wastewater, liquor and chemical recovery projects.

Veolia provides its clients an integrated approach to water and resource management using innovative technologies, equipment, chemistry, and services. Our customer-focused culture combined with comprehensive capabilities make Veolia the preferred partner for all water, wastewater, evaporation, and crystallization projects.


Veolia is experienced in the design and implementation of standard and customized technologies and processes for the Pulp and Paper industry

Black Liquor Concentration 

The thermal treatment of black liquor through evaporation achieves higher solids content and lower loads to the recovery boiler leading to the optimization of combined heat and power production. When integrated within the chemical recovery cycle, this technology promotes higher operational efficiencies while enabling the reuse of high-quality condensate.

Precipitator Ash Treatment

With the closing of process loops, chloride and potassium accumulate in the recovery cycle and result in scaling and corrosion in the boiler. Using highly-selective crystallization technologies, these non-process elements (NPEs) are removed while sodium is recovered to maximize soda chemical savings.

Influent (Raw) Water Treatment

Regardless of the source of the intake water, Veolia technologies ensure there is a consistent supply of water to the facility.  

Utility Water

Pulp and paper manufacturers rely upon their utility operations to provide steam and cooling water to support production. Veolia’s equipment and chemical technologies effectively produce the type of water your utilities need to ensure reliable steam quality, heat exchange efficiency and environmental compliance.


Veolia is experienced in helping clients reduce their financial exposure and comply with discharge requirements and stringent environmental regulations. 

Water Footprint Reduction

To reduce a facility's water footprint, Veolia offers a wide-variety of water reuse technologies. From debarking wash water to wastewater reuse, Veolia helps companies optimize the use of water in their facility.

Pulp & Paper Raw Water Case Study

Irving Paper

Featured Technology: Actiflo® - High Rate Clarification

Location: New Brunswick (Canada)

Project Information:

Irving Paper was looking to reduce water usage by 6,000 m3/day in summer and 8,000 m3/day in winter by cleaning and reusing certain process water streams. The mill's goals were to reduce raw water demand, improve process water quality, recover thermal energy and reduce wastewater flow. 

Veolia installed two Actiflo® package plants to treat wastewater from the vacuum pump seal. Wastewater from the mill's vacuum pump seal flows to the Actiflo® units and is blended with raw river water. The technology is able to remove 99.9% turbidity for the two water streams. As an additional benefit, this process helped the mill decrease energy costs by allowing the warmer reuse water to increase the temperature of influent water fom the river, prior to use in the mill.
