DuPont Water Solutions has entered into an exclusive global partnership with Sun Chemical and its parent company, the DIC Corp., to bring membrane degasification modules to market. The degasification of liquids is becoming increasingly critical to several water treatment processes, including industrial demineralization, oil and gas production, microelectronics manufacturing, pharmaceutical production, and drinking water treatment. The membrane degassing modules — branded Ligasep — are now part of DuPont’s portfolio of water purification and separation technologies, including ultrafiltration, reverse osmosis and ion exchange resins.
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 of dissolved gasses for a range of flowrates in water treatment applications.
