Feed Spacers for RO filter elements

Water is essential for life, and having access to potable and safe water is one of the key factors in maintaining health. Water filtration systems play a critical role in ensuring that our tap water is free from contaminants and other impurities that can impact our health.

Veolia, a leader in water technologies, will lead, via its subsidiary SIDEM, a consortium in charge of the engineering, procurement and construction (EPC) on the Mirfa 2 desalination project commissioned by Abu Dhabi National Energy Company PJSC (TAQA) and ENGIE. Located in Abu Dhabi, this state-of-the-art Reverse Osmosis Desalination will be the third-largest desalination plant in the United Arab Emirates (UAE). With a production capacity of 550,000 cubic meters per day of potable water, it will provide clean drinking water to approximately 210,000 households while offering increased efficiency and a reduced environmental footprint. The contract represents revenue of approximately 300 million euros for Veolia. Project construction will begin in Q2 2023 so the plant can be commissioned by 2025.

Most of the drinking water used in the UAE comes from the sea. To manage the growth in water consumption and to compensate for the aging of existing facilities, mainly thermal desalination plants, the country has decided to use the latest advanced technologies and engineering processes to increase its desalination capacity while reducing its energy consumption. A strategy that strongly supports the country’s 2050 carbon neutrality ambition.

Relying on Veolia’s worldwide expertise in water desalination, the Mirfa 2 plant will follow the latest developments in environmental and efficiency standards for desalination, featuring advanced technological processes such as reverse osmosis, which represents strong efficiency gains compared to traditional thermal desalination, to lower energy consumption and improve productivity. These technological advancements allow to slash energy use by 80% compared to the 1980s, when thermal desalination was predominant. www.veolia.com

Naltex™ diamond nettings are used as feed spacers for spiral wound water filtration membrane elements for Reverse Osmosis, Nano, Ultra, and Micro Filtration. Naltex feed spacers are specifically designed to optimize the hydraulic conditions of the feed water by creating turbulence on the membrane surface which reduces fouling and pressure losses through the membrane element. These specially crafted spacers are made by a strong yet flexible plastic mesh that provides superior hydraulic flow capability which improves the flux of the membrane. In addition, their unique design helps to evenly disperse the feed water across the filter surface, providing optimal contact time with the filter media and improving overall filter performance. Naltex™ feed spacer technologies can improve the efficiency of your water filtration system by increasing the flux of each membrane element while also extending the life and robustness of a membrane element by reducing fouling on the membrane surface contributing to less cleaning and maintenance downtime.

Naltex™ diamond nettings are made of FDA approved materials, offering superior strength and flexibility. Additionally, all Naltex™ products are tested to ensure they meet strict standards for lead, chlorine and other contaminants commonly found in drinking water. With regular cleaning and maintenance, these diamond nettings can extend the life of your filter while ensuring safe, pure water for your entire family. www.gessner-filtration.com
