Chemistry coupling boosts treatment

DuPont ligsep

DuPont Water Solutions has entered into an exclusive global partnership with Sun Chemical 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™— can be easily integrated into a degassing system and offer the advantage of minimum water pressure drop with no added chemicals or airborne water contamination, says the firm.

The Ligasep™ product line utilizes 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.

DuPont says the partnership supports its 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.

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

DuPont’s portfolio of water purification and separation technologies also includes ultrafiltration, reverse osmosis and ion exchange resins.
