Lignin Removal Process (LPR)

The Pulp & Paper industry witnessed a significant degree of evolution over the last decade, starting with the move from the era of printing to that of packaging and tissue paper production. In a setting of consolidation, segment concentration and increased public awareness, large Pulp & Paper producers are faced with increased pressure to source responsible raw materials, meet stringent environmental regulations such as use less energy and water, create less waste, and ensure clean effluent streams, and need to grow and prosper in a more sustainable and low carbon way.

Overview

The industry uses large quantities of water to produce finished products hence discharging large quantities of effluent into the environment (river, sea, etc.). The yellow color property of Pulp & Paper wastewater is due in part to high levels of lignina challenging contaminant that once removed results in a clear water stream.

How can we help?

SUEZ has developed a new Lignin Removal Process that uniquely removes color and hard-to-degrade organic compounds associated with lignin in Pulp & Paper effluent water. This polishing process is particularly effective with MBR technology. It enables our Pulp & Paper customers to discharge in a cost-effective way a clear effluent back to the rivers the water came from, or for reuse in their process. 

The ideal process to achieve high-quality water suited for discharge or reuse

Features & Benefits

What this means for you:

  • Meet regulatory compliance - achieve a high color and hard-to-degrade organic compounds removal (>80% COD) to meet regulations

  • Reduce environmental footprint - achieve high-quality water for safe discharge in the environment, ensuring that only a colorless stream is discharged from your plant

  • Increase water reuse - LRP effluent is well suited for reuse applications to reduce a plant's water footprint and manage water scarcity risks

  • Reduce energy - the lignin-rich resource stream provides more fuel to the recovery boilers reducing the amount of required external fuel.

  • Holistic Portfolio - leverage a complete set of water, energy and waste management solutions from one provider
