Advancing new-age, industrial technologies to address wastewater management and foster clean water solutions for a sustainable tomorrow, DuPont Water Solutions (DWS), a global leader in water purification and separation technologies, featured its range of water solutions and technologies at IFAT from September 28-30.
Laying emphasis on pressing environmental concerns such as sewage systems management, adequate waste-water treatment, sustainable ways for water supply, holistic solid waste management and recycling, amongst others, the three-day event provided a platform to expand DuPont's network with industry experts, innovators, business partners, government officials and consumers. IFAT is India's leading trade fair for Water, sewage, solid waste and recycling.
“In the world where the compounding effects of the climate crisis are looming large, availability of freshwater is in major threat as industries continue to release untreated effluents into water bodies. We are simmering a tech revolution of sorts to create a future with clean, healthier water by bringing in enhanced tech solutions like reverse osmosis, ultrafiltration and many more,” said Chrys Fernandes, Business Head- India subcontinent, DuPont Water Solutions.
Over the last few decades, DWS has partnered with industry players and consumers to contribute to the United Nations 2030 Sustainable Goals. “We are not far from the deadline and to achieve the 2030 goals, we are putting the best brains and talent together for solving the most pressing water issues that are further stressing the environmental concerns,” Chrys, added.
Products on display by DuPont Water Solutions at IFAT
Membrane Bioreactor Systems (MBR): MBR combines biological waste oxidation and membrane filtration. The technology uses a fully automated process for separating liquids and solids. Using MBR eliminates the need for secondary clarification, making it more efficient compared to conventional methods. With more than 30 years of experience in MBR, DuPont's technology saves footprint on sites with limited space; improves effluent quality, allowing water reuse; allows for plant expansions in the same footprint; and uses a smaller biological process
Ultrafiltration (UF) is a pressure-driven purification process. UF separates particulate matter from soluble compounds using ultrafine membrane media. Along with highly efficient UF modules, DuPont's range offers cost-effective, space-saving rack designs, through products such as DuPont™ IntegraPac™ and T-Rack®, for water treatment plants. The expansive UF portfolio includes both Polyethersulfone (PES) and Polyvinylidene fluoride (PVDF) membranes for pressurised and submerged configurations. The technologies are available as stand-alone, pre-packaged units or as components for large projects. Benefits of UF for water treatment include reliable removal of microorganisms, viruses, and pathogens; consistently high-level filtrate quality; maximum stability, minimal fibre breakage; long service life and high availability and high performance with low operating costs.
Ion exchange resins (IER) allow the reversible interchange of ions between a solid and a liquid. Ion exchange resins remove harmful contaminants from liquids, replacing them with beneficial, desired ions. Water treatment facilities use IER for applications such as industrial demineralisation, condensate polishing, ultrapure water production, and wastewater treatment. Over the last 80 years, DuPont's IER portfolio has evolved to become one of the most comprehensive in the industry with products such as DuPont™ AmberLite™ and DuPont™ AmberLyst™.
Reverse osmosis (RO) and Nanofiltration (NF) is a pressure-driven separation process that employs a semipermeable membrane and the principles of crossflow filtration. The RO membrane acts as a barrier to all salts and inorganic molecules, as well as many organic molecules. NF provides high rejection of multivalent ions such as calcium and low rejection of monovalent ions such as chloride. The FilmTec™ and DuPont™ TapTec™ portfolio offers separation-technology products that are highly effective in industrial, municipal, commercial, and consumer water applications. The combination of these technologies offers unique benefits such as two to three times more high-quality water; filters out a higher percentage of dissolved solids; removes up to 99 per cent of impurities from water; reduces operating costs and lower energy use; and longer membrane life due to antifouling and easy maintenance.
Closed Circuit Reverse Osmosis (CCRO): RO systems are typically designed to meet specific conditions, but most deal with temperature variations, feed concentration, consumption flow rates, and fouling and scaling conditions. CCROs adapt to such changes with flexible and independent control over recovery, crossflow, and flux. With data-driven intelligence, CCRO systems can operate from 42 per cent to 98 per cent recovery on a wide variety of water sources and applications. The benefits of using CCRO technology include autonomous adjustment to a wide range of conditions; significant reduction in maintenance and downtime; 50–90 per cent less water waste and lLower energy consumptions
