Big cities like Paris can get extremely hot during summer. When concrete structures heat up, summer in the city can get awfully exhausting, and citizens are craving for a swim. After 102 years, Paris has re-opened the Seine river for public swimming. Award-winning technology is a key enabler.
The Finnish forest industry group, Metsä Group, is developing a new wood-based textile fiber called Kuura™. Kemira is collaborating with them as the main chemistry partner, enabling process feasibility and safety across the entire water-based process, as well as scale up of the fiber production.
The wastewater treatment plant in the city of Hamburg opted for a renewable, biomass-balanced polymer, as an additional step toward smore sustainable operations.
How much are unpredictable raw water conditions costing your operations in chemical overuse and production inefficiencies? Consistent raw water quality is critical for smoothly running pulp and paper processes, but achieving it cost-efficiently is a practical challenge.
The wastewater from DAKA´s production process varies with challenging compositions. The effluent is released to a highly sensitive recreational area. Automated monitoring and dosing technology is helping to achieve a consistent quality in compliance with regulatory requirements.
Cooling off in a local lake or river is one of the joys of summer – as long as wastewater discharged there has been properly cleaned. Berliner Wasserbetriebe implemented a safe, effective and sustainable solutions at its biggest treatment plant, to achieve compliance with EU bathing water directive.
As an additional measure to make operations more sustainable, the Paljasaare wastewater treatment plant in Estonia´s capital city Tallinn decided to switch from conventional fossil-based Polymers to a renewable, biomass-balanced alternative product.
The tourist hotspot of Kalajoki on Finland’s west coast is well known for its stunning scenery and pristine nature. The region’s water utility company, Vesikolmio, is helping to protect this beautiful area with fast, effective wastewater disinfection using Kemira’s KemConnect® DEX technology.
In preparation for the Paris Olympic and Paralympic swimming events in the river La Seine in 2024, the Greater Paris Sanitation Authority trusted Kemira with it´s performic acid solution, KemConnect® DEX, for their project of disinfecting treated wastewater before discharging.
The Lotsbroverket wastewater treatment plant in Mariehamn has seen excellent results after implementing Kemira´s KemConnect® PT digital service. This data-driven solution for primary wastewater treatment has reduced the energy consumption and cut ferric sulfate consumption at the plant.
