Water treatment for the paper industry

The paper industry consumes between 2 and 18 m3 of water per ton of paper, according to the effluent management system, giving rise to the need to treat the wastewater and sludge generated.

Growing consumer environmental awareness, the cost of water and energy, and increasingly stringent environmental regulations require companies in the sector to optimize their processes to increase efficiency and reduce their environmental footprint.
