Our most valuable asset?

It is hard to overstate the importance of fresh water. Everything we drink and eat – meat or vegetable – requires fresh water. And though many do not realize it, every source of energy we have uses fresh water at some stage of the process.

Behind the price tag of a wastewater treatment plant

The majority of existing wastewater treatment infrastructure was designed and commissioned decades ago. Today, municipalities are facing increasing demands on capacity with urbanization. When funds for new investments are tight, it pays back to carefully study the impact of different treatment process setups on total lifecycle costs.

Time to switch gear in water treatment

The formula to reduce your carbon footprint in wastewater treatment

The water treatment industry consumes significant amounts of energy. Depending on the chosen treatment method, process energy-usage can be lowered and sustainable energy produced to benefit operations, society and the environment alike.

Why combine biological and chemical wastewater treatment?

While acknowledging the invaluable role that biological processes play in wastewater treatment, chemical treatment brings some significant, measurable benefits when it comes to energy and plant optimization.

Putting unutilized by-products back into the circular economy

On October 24, 2019, Kemira won the European Responsible Care Award for a project turning unutilized by-products into a valuable raw material.

Stepping on the (bio)gas in Miami-Dade

The Miami-Dade South and Central District Wastewater Treatment Plants in Florida had been struggling with the twin challenges of suboptimal concentrator settling and poor-quality biogas from their anaerobic digesters. Using application expertise and experience from other Floridian customers, Kemira experts knew exactly the right way to tackle both problems at once.

Good cooperation saves the summer season in Étretat, France

After fire damaged the wastewater treatment plant in Étretat, there was no time to lose. Thanks to good cooperation, the plant’s new disinfection solution was up and running just seven days after the fire.

Why chemical treatment is a no-brainer

Because people tend to associate “bio” with sustainable, municipal operators may think that biological phosphorus removal must be more environmentally friendly than the chemical alternative. Studying the facts reveals a slightly different story.
