Nalco, an Ecolab company based in the U.S., and Wetend Technologies Ltd, a technology and innovation company based in Finland, have reached a global patent settlement agreement that includes the dismissal of a current lawsuit between the two companies. The terms of the settlement are confidential.

Both Nalco and Wetend Technologies operate globally and have businesses that serve forest products-based process industries, including paper and board mills. The patent dispute involved the use of process mixing technologies for the forest products industry.

Going forward, the companies will collaborate to provide injection mixing technologies to their customers that provide superior environmental results, including the elimination of use of fresh water, reduced use of energy and chemicals and reduced carbon dioxide emissions.

Eka Chemicals and Wetend Technologies Ltd have agreed to market and deliver TrumpJet® Flash Mixing Systems together with Eka’s wet end chemicals to the paper industry globally.

The TrumpJet® brand offers a range of chemical and additive mixing systems for paper mills, including paper and board machine wet end, stock preparation, recycled fiber and mechanical pulping process applications.

AkzoNobel’s Pulp and Paper Chemicals business, Eka Chemicals, produces and supplies a wide range of chemicals, including the unique Compozil® retention and drainage system for the paper industry globally.

“The combination of high performance chemicals and an advanced chemical mixing system will benefit the paper and board industry, both in terms of cost savings and environmental gains,” says Lennart Nilsson, Director Global Marketing at Eka Chemicals.

“This offer will definitely have a positive impact on wet end efficiency and contribute to a sustainable paper machine operation,” adds Jouni Matula, CEO at Wetend Technologies.

·         Reduced APAM consumption >30-40%

·         Total and filler retention unchanged

·         Improved operation of centrifugal cleaners with less

·         good filler in rejects of cleaners

·         Consumption of optical brightener slightly reduced

·         ASA consumption or sizing unchanged

·         Quality unchanged

·         Formation unchanged

·         Tensile MD/CD slightly better or the same

·         Bonding strength the same

·         CD/MD profiles unchanged

·         Dewatering unchanged

·         Total net efficiency increased

The mixing system has been istalled on fine paper production line producing 350.000 tn/a with a world speed record paper machine running speed 1700m/min.

The Trumpjet systems supplied worldwide save 42 million square meters of fresh water, 1,6 MWh of energy and reduce 1 million tons of CO₂ emission annually.
