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:
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.
BrineRefine Chemical Softening System
Smart, compact, modular chemical softening system that reduces costs with precision dosing and built-in solids management. Improves recovery and minimizes fouling risk with intelligent controls that communicate with downstream assets, like RO or evaporators.
SaltMaker
MultiEffect
Modern, modular, and intelligently automated evaporator-crystallizer that concentrates brine or produces low volume solids for zero liquid discharge.
XtremeRO/NF Brine
Concentrator
Next-generation water-maker and brine-concentrator based on reverse osmosis that achieves extreme freshwater recoveries, enabling cost-effective brine management and treatment of challenging organic-laden waters including oil & gas produced waters.
XtremeUF
Ultrafiltration System
An ultra-robust ceramic based ultrafilter that can remove suspended solids, oils, and grease from the most challenging slurries and impacted wastewaters. XtremeUF cleans itself as it operates, to ensure your membranes maintain performance.
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.
