DuPont partners with Sun Chemical on water treatment solutions

DuPont has added degasification to water treatment solutions to its range through exclusive partnership with Sun Chemical and its parent company DIC Corporation

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 water treatment processes, including industrial demineralisation, oil and gas production, microelectronics manufacturing, pharmaceutical production, and drinking water treatment. The membrane degassing modules -branded Ligasep- are now 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.

HP Nanda, Global VP & General Manager, DuPont Water Solutions, said: "We look forward to working with Sun Chemical and DIC to better meet the needs of our customers focused on water treatment and reuse."

Ligasep modules can be easily integrated into a degassing system and offers minimum water pressure drop with no added chemicals or airborne water contamination.

"We're extremely proud to be partnering with DuPont Water Solutions to bring an all-encompassing solution to the market," said Mehran Yazdani, President of Advanced Materials at Sun Chemical Corporation. "This collaboration will allow our water treatment customers to be better served with a single sourced product solution that meets their requirements and expectations."

The Ligasep product line utilises a PMP (polymethylpentene) hollow fibre 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.

"This is an incredible opportunity for DIC and DuPont to introduce a single water treatment solution for customers," said Kaoru Ino, President and CEO, DIC Corporation. "One of our goals as an organisation is to provide comfort to the world around us. One way to do that is through water safety."

The exclusive alliance with DuPont Water Solutions only applies to the water treatment marketplace. Sun Chemical will continue to manufacture and sell its SEPAREL membrane degassing technology to other industrial markets, including the inkjet marketplace.
