African copper producer cuts froth in challenging conditions

A hydrometallurgical facility in the African copper belt was struggling with froth, a common issue in plants that process highly carbonaceous material. Not only was the froth causing operational issues, it constrained capacity, leading to production losses of approximately $5 million a day. Kemira KemFoamX^TM 9980 brought it under control.

Award-winning breakthrough in phosphorus recovery

What is the most sustainable and reliable way to recover phosphorus from wastewater? The jury for the project innovation competition at the IWA World Water Congress & Exhibition decided that one of the most promising technologies is ViviMag®, granting it the silver award in the “Breakthroughs in Research & Development” category.

New bio-flocculants for water utilities

When wastewater treatment plants make the switch to biobased polymers, it can be a win for the planet. But what about performance? New Superfloc® BioMB, the world’s first line of biomass balanced flocculants, offers reliable performance and clear sustainability benefits.

Biobased polymers in water treatment – first experiences

In this on-demand webinar you will learn why HSY has opted for Kemira’s novel biomass balance polyacrylamide, a water-soluble polymer, for their sludge dewatering process, and how it is contributing to HSY´s sustainability performance.

Digitalization for sustainable water

In this webinar you'll hear real-life municipal case studies for different wastewater treatment applications and the impact of digital optimization on process efficiency and environmental performance.

Energy use reduction in wastewater treatment

From climate change to eutrophication, wastewater treatment plants (WWTPs) are adapting their operations in the face of environmental challenges. A recent Life Cycle Assessment suggests that the best way for wastewater treatment plants to improve their energy balance and overall sustainability is a tailored mix of chemical and biological treatment methods.

Digitally enabled primary wastewater treatment

How can water utilities comply with tightening regulations while reducing energy use, raw material consumption, and carbon intensity at the same time? Proven digital solutions are available to replace manual dosing and guesswork.

Primary wastewater treatment - New opportunities for sustainability

Watch this on-demand webinar to learn how new, digitally improved chemical pre-treatment is helping municipalities comply with tightening regulations, while optimizing their energy balance and maintaining stable treatment processes.

Sustainability steers innovation at Copenhagen’s wastewater treatment plants

Sustainability focus is changing the way municipalities manage wastewater. But change doesn’t happen overnight. Utilities everywhere can take inspiration from Copenhagen’s wastewater treatment, where in-house researchers are reducing greenhouse gas emissions, and contributing to the circular economy by increasing biogas output.
