Industrial Wastewater

Bringing the most reliable and effective treat-for-purpose solutions to your wastewater challenges.

Suspended solids removal with Ultrafiltration

Dupont Water Solutions offers a wide selection of Ultrafiltration (UF) technologies to address complex pretreatment challenges for industrial wastewater. DuPont IntegraFlux™ and IntegraPac™ in-side-out PVDF pressured UF modules and skids provide exceptional reliability, outstanding membrane separation, extreme productivity, and efficiency on more than 500 industrial wastewater installations worldwide. DuPont MEMCOR® UF is a result of 30 years of innovation in PVDF submerging UF with reduced capital and operational cost. The super compact skids design minimizes footprint for industrial wastewater applications. DuPont inge® out-side-in PES pressured UF offers unique strong multi-bore fiber structure with T-Rack skids designed to maintain competitive total cost of ownership, while managing a reliable and profitable operation in industrial wastewater.

Total Dissolved Solids (TDS) removal with Reverse Osmosis Brackish Water Elements for Wastewater Treatment

FilmTec™ Fortilife™ RO Portfolio tackles the most challenging industrial wastewaters and applications, with reliable performance and expert support from DuPont. FilmTec™ Fortilife™ Elements can help you to reduce water costs, achieve sustainability goals, minimize fouling problems, and move toward Minimal Liquid Discharge (MLD).

• FilmTec™ Fortilife™ CR200 Elements: Reduce shutdowns and chemical use from cleanings by up to 50% and energy costs by as much as 20% in operations with fouling prone waters.
• FilmTec™ Fortilife™ CR100 Elements: Reduce shutdowns and chemical use from cleanings by up to 50% and energy costs by as much as 10% in operations with fouling prone waters.
• FilmTec™ Fortilife™ CR50 Elements: Contaminant resistant and offers long element lifetimes and reliable system performance when treating biological and organic fouling prone waters.

Softening & Dealkalization with Ion Exchange Resins 

DuPont™ AmberLite™ ion exchange softening resins remove cations associated with hardness (such as Ca and Mg) from industrial wastewater to avoid scale formation caused by precipitation of sparingly soluble salts like calcium carbonate. Ion exchange resins (IER) can also remove bicarbonate alkalinity associated with scaling.

Bringing a more cost-effective approach to your wastewater challenges.

Evolving wastewater regulations can create demanding and sometimes costly production challenges. Factors such as the rising price of water and the significant cost of zero liquid discharge (ZLD) can greatly affect your ability to meet production goals. Many facilities are seeking an alternative to ZLD. Not only is it expensive, but it’s not necessarily the most environmentally friendly process because of the energy and resources it requires.

DuPont Water Solutions can help address your wastewater regulatory challenges with our minimal liquid discharge (MLD) solution. MLD has the potential to minimize your operating costs and maximize water recovery while reducing the amount of energy required to operate. With the industry’s broadest portfolio of purification and separation technologies, we can help you achieve your MLD goals and get you on a path toward cost savings, higher recovery and improved environmental stewardship.

• FilmTec™ Fortilife™ XC70 Elements: Maximize pure water recovery while reaching brine concentrations >70,000 ppm TDS with reduced shutdowns for cleaning and high permeate quality.
• FilmTec™ Fortilife™ XC80 Elements: Reduce the volume of the downstream brine treatment process by reaching concentrations >80,000 ppm TDS with reduced shutdowns for cleaning.
• FilmTec™ Fortilife™ XC120 Elements: Reduce the volume of the downstream brine treatment process by reaching concentrations >120,000 ppm TDS while operating within standard RO equipment limits.

Industrial wastewater’s vast potential as a source of valuable resources, such as recovering salts and other chemical compounds, is evolving as a means to use circular economy to increase sustainability and affordability of water recycle systems. DuPont’s resource recovery approach uses a core set of proven ultrafiltration, reverse osmosis, nanofiltration, and ion exchange-based technologies and processes that enable users to recycle high quality chemical salts from the wastewater stream. Enabled by DuPont’s technologies, China's Coal to Chemical industry recovers high quality sodium chloride and sodium sulfate from its wastewater MLD process and reuse those salts for other industries like chlor-alkali, soda, dying, leather processing, and construction. Salts recovery not only help facilities reduce operational costs, but also their carbon footprint, enabling increased revenue streams through carbon credits and carbon trading programs.

• FilmTec™ Fortilife™ XC-N and XC-N HP Elements: Reduce costly waste by converting a large fraction of the RO concentrate into purer, easier to crystalize salt solutions for salt recovery.

Landfill leachate are waters with high organic and inorganic pollutant concentrations leached from landfill through rainwater intrusion. Landfill leachate is extremely toxic to the environment and is one of the major threats to aquifer and surface water health. DuPont Water Solutions offers proven treatment solutions employing ultrafiltration, reverse osmosis, and nanofiltration to treat landfill leachate to meet wastewater discharge standards for over 1000 installations worldwide.
