Pushing wastewater treatment capacity limits at Stockholm Water

Serving the wastewater treatment needs of a rapidly growing population has presented challenges for Stockholm Water. With one of its treatment plants undergoing an upgrade and another close to full capacity, the company is benefiting from Kemira’s expertise to increase capacity with the help of chemical pre-treatment.

Safeguarding health and safety at SWISS KRONO

SWISS KRONO, a manufacturer of wood-based materials, wanted to safeguard the health and safety of its employees by disinfecting the wastewater generated at their largest production plant. Read how we helped them with the Kemira KemConnect solution.

Towards a cleaner Baltic Sea using Kemira's hydrogen

This summer, Aranda, a research vessel of the Finnish Environment Institute (SYKE) operating in the Baltic Sea, will start the experimental use of a fuel cell system fueled by excess hydrogen from Kemira’s Äetsä plant in a pilot project coordinated by the VTT Technical Research Centre of Finland.

Sludge treatment – great opportunities for improvement

Sludge dewatering can be a tricky operation due to varying sludge composition. A significant share of the operational costs of municipal wastewater treatment but also some industries is in sludge disposal. An investment into improved sludge treatment can bring significant cost-efficiencies.

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

Most municipal wastewater treatment plants are already reaching a good level in terms of their capability to meet regulatory requirements and manage day-to-day challenges; now it is time to switch gear and focus on optimizing processes and reducing resource consumption.

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
