Boiler Feed Water Treatment

DuPont multi-tech solutions.

 
 
 

Reduce plant downtime and protect steam generation systems with DuPont's advanced water treatment technologies

Boilers receive feed water consisting of varying proportions of recovered condensed water (return water) and fresh water, which has been purified in varying degrees (make-up water).

High purity feed water is required to ensure proper operation of industrial steam generation systems to produce high-quality steam and transport heat throughout an entire facility.

Treating boiler feed water is essential for both high- and low-pressure boilers. Removal of organics, suspended particles, dissolved minerals, and dissolved gases is critical to avoid scaling and fouling, which will lead to failure of the boiler and downstream equipment, plant downtime, and expensive maintenance fees.

Specific treatment processes vary depending on the requirements of the boiler and the quality or chemistry of the feed and make-up water. DuPont offers comprehensive solutions for your boiler feed water challenges that can achieve your desired quality levels, leading to optimized water use, reduced asset corrosion and boiler downtime, and ultimately trimmed operational costs.

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.

 

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.

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.
