Water & Wastewater Treatment

for Pulp & Paper Manufacturers

Veolia Water Technologies has been providing water and advanced water and wastewater treatment technologies for more than 60 years. 

With experience in every aspect of water and wastewater treatment, Veolia can provide pulp and paper companies with advanced and reliable solutions that creates superior water quality for plant operations or ensures regulator compliance of the wastewater prior to discharge.

Our Expansive Water & Wastewater Treatment Technologies Include:

Biothane® High-Rate Anaerobic Treatment System

Anaerobic granular wastewater treatment process designed to effectively remove COD/BOD, while simultaneously generating green energy as a by-product.

AnoxKaldnes™ MBBR

(Moving Bed Biofilm Reactor)

High-performance aerobic wastewater treatment technology engineered to effectively remove BOD/COD and nitrogen

AnoxKaldnes BAS™

Biological Activated Sludge Process

Specialized MBBR (Moving Bed Biofilm Reactor) process that removes easily biodegradable COD and protects the activated sludge system from peak loads and improved sludge settling

Anita™ Mox

Advanced Nutrient Removal Technology

Specialized biological process to treat wastewater streams that have high concentrations of ammonia

Actiflo® High-Rate Clarifier

Small-footprint technology in which water is flocculated with microsand and polymer to increase settling velocity for the removal of more than 99% of TSS 


Drumfilters & Discfilters

Filtration technology that uses woven media panels to remove suspended solids > 10 microns 

Multiflo® High-Rate Softener

Proprietary softening process that incorporates chemical precipitation with sludge thickening to produce an effluent with low concentrations of scale-formers and a highly concentrated sludge that can be easily dewatered

Ion Exchange Systems

Flexible and automated water treatment systems used to soften, dealkalize, deionize, or demineralize water for utility or process applications  

IDRAFLOT® Dissolved Air Flotation (DAF)

An innovative and effective technology for pre-treatment or tertiary treatment that effectively separates fibers and suspended solids

Sand, Multimedia, Carbon, and Cartridge Filters

Efficient equipment designed to remove particles, odors, and organics to improve intake water quality for use in utilities and other production areas

Reverse Osmosis (RO) Systems

Advanced membrane based water filtration systems engineered to create a high-quality permeate for water reuse applications

Pulp & Paper Case Study

Leading Recycle Paper Mill

Technology: Biothane® EGSB (Expanded Granular Sludge Bed)

Project Information: A recycle paper mill was needing to upgrade their wastewater treatment facility to improve COD removal and Calcium removal as pretreatment before ZLD (Zero Liquid Discharge). Additionally, the facility needed to have reliable wastewater treatment to ensure regulatory compliance. 

Veolia installed two (2) Biothane EGSB (450 m3 each) to replace their existing anaerobic system. The facility was designed to treat up to 1,320 m3/day with loading rates up to 12,700 kg COD/day. As a result, the system was able to remove 80% of the COD and with its calcium removal step, it was able to prevent scaling in the downstream ZLD process.
