Pulp and paper
Paper is an essential part of our lives – we use it every day for school, work, and leisure. While paper recycling has grown tremendously over the last few decades, paper mills still consume significant amounts of raw materials, as well as water and energy.
In a time when water and energy scarcity is a growing issue, Aqana’s technology can provide a simple yet robust solution to create energy from wastewater and simultaneously reduce the organic pollutants in paper mills.
What are the main pollutants in wastewater in the pulp and paper industry?
The pulp and paper industry wastewater compositions can change in quantity, and quality and may contain:
- organic compounds – such as acetic acid, ethanol, methanol, lignin, phenol,
- sulfur compounds such as sulfate, sulfite, and sulfide
- inorganic suspended matter,
- chemicals such as pigments, bleach,
- and other specific substances.
Why is it crucial for pulp and paper companies to treat their post-production wastewater streams?
The paper production industry still is one of the most water-intensive industries in the world.
Every year, paper mills withdraw billions of gallons of water from rivers, lakes, and aquifers to use in their paper-making process.
This water is used to clean and break down pulpwood chips into paper fibers. Once the paper is made, it is then coated with chemicals and dyes before being dried and rolled into sheets.
The wastewater generated by this process contains a variety of pollutants, including suspended solids, organic matter, chlorine, and heavy metals.
If this wastewater is not properly treated, it can pollute waterways and harm aquatic life.
