Water is an essential ingredient to the pulp and paper industries. Wastewater from pulp and paper processes may face regulatory scrutiny due to risks to aquatic life.
Wastewater concerns may include:
Reverse osmosis (RO) concentrates waste streams for disposal and recovers fresh water for processing. We can help you get the most out of RO with a suite of products that maximize performance, cost-effectiveness, and longevity:
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.
This article introduces a new type of ceramic membrane system and explains how it opens the application range. An example of treatment of oil and grease in produced water is provided.
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.
