PAPER & PULP
Pulp & Paper Wastewater
Paper is vital to a vast swath of products and consumer goods—and water is an essential ingredient to the pulp and paper industry. The resulting wastewaters may face some treatment challenges and regulatory scrutiny, in particular due to risks to aquatic life.
Wastewater concerns may include:
- residual bleaching agents, such as hydrogen peroxide
- reducing consumption by increasing water reuse
- total suspended solids (TSS) and turbidity
- biochemical oxygen demand (BOD/COD)
- organics (especially organochlorides)
Saltworks Can Help
Saltworks’ experts can help you to understand your options, including treatment, discharge regulations, and economics.
To decide on an appropriate and cost-effective treatment process, it is critical to know the wastewater chemistry in detail and understand the treatment goals and capacity needs.
Saltworks can review water chemistry and specific project requirements so that a treatment process is chosen that balances simplicity, cost-effectiveness, and reliability. Contact us for project reviews, water testing, pilots, and more.

Excessive phenolic compounds are harmful to human health and the environment. Chlorophenols, by-products of chlorinating phenol-containing water, are carcinogens. A treatment system needs to be chosen and engineered carefully, with consideration of specific wastewater chemistry, operating conditions, and economics.
There are many sulfate treatments available, with different advantages and disadvantages. Factors for consideration include capital and operational costs, solid Vs. liquid brine reject for disposal, if the need is seasonal or year-round, and suitability for adverse operating conditions.
Convention teaches that ZLD requires energy-intensive boiling to produce solids. Our engineers recently broke that convention and helped a mining client achieve solid salt production in a novel membrane-chiller hybrid plant using UHP-RO.
