DuPont Water Solutions
To better serve its industrial water treatment customers, DuPont Water Solutions has entered into an exclusive global partnership with Sun Chemical and its parent company, the DIC Corporation, to bring membrane degasification modules to market. The degasification of liquids is becoming increasingly critical to several industrial processes, including industrial demineralization, oil and gas production, and microelectronics manufacturing. The membrane degassing modules — to be branded Ligasep™— will become part of DuPont’s leading portfolio of water purification and separation technologies, including ultrafiltration, reverse osmosis and ion exchange resins.
The partnership supports DuPont’s goal to increase access to the products and technologies needed to meet global customers’ current and future challenges, including the increased need to recycle water while reducing the energy requirements to generate clean water.
Ligasep™ can be easily integrated into a degassing system and offers minimum water pressure drop with no added chemicals or airborne water contamination.
The Ligasep™ product line utilizes a PMP (polymethylpentene) hollow fiber membrane which is used to remove dissolved gases, such as oxygen and carbon dioxide, from water to prevent oxidation and reduce the ionic load on downstream processing equipment. Control of these gasses is an integral part of producing high quality water used in the power generation, industrial manufacturing and semiconductor industries. These modules can be installed in series within the same water treatment system, ensuring sufficient degasification and achieve ppb levels (parts-per-billion) of dissolved gasses for a range of flow rates in water treatment applications.
