Industrial Utility Water

DuPont multi-tech solutions.

 
 
 

Reliability and efficiency with DuPont’s industry-leading multi-tech portfolio of filtration and purification technologies.

Water is a critical vector of nearly all industries, directly impacting both production uptime and profitability. Today, the manufacturing industry accounts for 16% of global water demand, and up to 22% by 2030. The United Nation’s Sustainable Development Goals 2030 target is to substantially increase water-use efficiency across all sectors, ensure sustainable withdrawals and supply of freshwater to address water scarcity, and substantially reduce the number of people suffering from water scarcity.

At DuPont Water Solutions, we develop integrated, effective solutions that meet the world’s growing water and energy demands. Our diverse portfolio of technologies and solutions address a broad range of water-treatment applications and are designed to help you overcome water challenges to produce your desired quantity and quality of industrial utility water.  Our best-in-class technical team, supported by R&D, has accumulated decades of experience across all technologies to create solutions that address each site’s challenges. Our understanding of water chemistry and the complexity of individual constituents enable us to recognize project needs and critical requirements.

Pretreatment with Ultrafiltration

DuPont Ultrafiltration (UF) is a pressure-driven purification process that separates particulate matter from soluble compounds using an ultrafine membrane media. Compared to traditional media and sand filters, UF technology offers: better & consistent filtrate quality regardless feedwater quality upsets; minimum to no use of pretreatment chemicals (polymers, coagulants, pH adjustment) and associated costs for sludge disposal; smaller footprint and lower weight. DuPont offers a wide selection of UF modules, skids, and systems that provide industries with peace-of-mind solutions to address their challenges while maintaining lowest total cost of ownership and managing a reliable and profitable operation.

 

Biofouling Prevention with B-Free™

DuPont™ B-Free™ pretreatment is a novel vessel-based media technology that efficiently mitigates the effects of biofouling in reverse osmosis (RO) systems, independent of the application. The B-Free™ solution is the result of a multi-year research and development effort that offers a reliable, easy-to-use, and sustainable solution. It is based on the B-Free™ pretreatment technology's ability to create an instant and sustained biostatic environment for downstream RO operations without the need for chemicals. It is resilient to upstream upsets, making it suitable for drinking water or industrial applications.

 

Total Organic Carbon Removal with Ion Exchange Resins

DuPont™ AmberLite™ SCAV Resins are organic traps that remove natural organic matter from feedwater to protect the demineralization system from fouling related operational issues and also reduce TOC in the treated water.  

 

Softening & Dealkalization with Ion Exchange Resins

DuPont™ AmberLite™ ion exchange softening resins remove cations associated with hardness (such as Ca and Mg) from feedwater 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.

Demineralization with Ion Exchange Resins

DuPont™ AmberLite™ ion exchange resins for demineralization are used to remove all cations, anions, and large organic contaminants from feed water.  DuPont has over 80 years of experience manufacturing the widest range of industry-leading, reliable ion exchange resins in world-class manufacturing facilities.

 

Demineralization with Reverse Osmosis Brackish Water Elements

FilmTec™ reverse osmosis (RO) elements are pressure-driven purification products that separate ions, dissolved salts, and minerals using a semi-permeable membrane. We provide the most comprehensive portfolio of high-quality, top-performing RO technology in the world, trusted globally by many industrial customers for over 40 years.

 

High Recovery Demineralization with Closed Circuit Reverse Osmosis

The patented DesaliTec™ SOAR closed circuit reverse osmosis (CCRO) system works by circulating water through a single stage of membrane elements until the desired recovery level is achieved instead of using complex traditional multi-stage methods. Brine is periodically replaced with fresh feedwater without stopping permeate flow. Recovery is flexible and can be set at the system control panel. The cross flow required for RO membrane operation is controlled with an internal circulation pump. Frequent and complete brine flushing prevents scale precipitation and disrupts biofouling, making very high recovery rates possible even from mineral-laden or contaminated feedwaters.

 

Degasification with Hollow Fiber Membranes

DuPont™ Ligasep™ degasification modules are a hollow-fiber-based technology that enable the removal of dissolved gases from water by physical means. These modules can be installed in-line with the water treatment system, ensuring efficient degasification and achieve even ppb levels (parts-per-billion) of dissolved gasses for a wide range of flow rates in water treatment applications, without chemicals.

Polishing with Ion Exchange Resin

DuPont™ AmberLite™ mixed bed ion exchange resins is the standard final polishing step for boiler make-up water and is a critical part of steam condensate treatment. Mixed bed polishers remove low ppm (parts per million) to ppb (parts per billion) range contaminants but can also protect a system in the event of condenser leaks, thereby improving plant reliability. DuPont offers a wide selection of polishing resins including premixed resins for non-regenerable systems.  

 

Polishing with Electrodeionization

DuPont electrodeionization (EDI) is a continuous and chemical-free process of removing ionized and ionizable species from the feed water using DC power. DuPont™ electrodeionization modules optimize performance, maintain continuous product quality and can produce up to 18 mega ohm-cm high purity water with high silica and boron removal.

DuPont™ Ligasep™ degasification modules are a hollow-fiber-based technology that enable the removal of dissolved gases from water by physical means. These modules can be installed in-line with the water treatment system, ensuring efficient degasification and achieve even ppb levels of dissolved gasses for a wide range of flow rates in water treatment applications, without chemicals.
