There’s no getting away from it – where there’s water treatment, there’s sludge. The more water you treat, the more sludge there is to deal with. So when Lahti Aqua was looking for a smart way to cut sludge management and disposal costs, they turned to Kemira’s KemConnect SD – and a groundbreaking performance-based agreement that’s making sure it’s a win-win for everyone involved.

Most of our water infrastructure was laid in the early to mid-20th century. With a lifespan of 75-100 years, we now have a situation brewing underground.

Taken for granted by millions around the world, clean, fresh tap water is a luxury that deserves far more appreciation than it gets. But piping it direct to your tap takes more than just a drop of smart engineering and a splash of chemistry.

Phosphorus is one of the vital building blocks for life. It is essential for example for animal feed and food production. At the same time, in wastewater it is a nuisance that needs to be removed. Pioneering solutions for both phosphorus removal and recycling is important to us, our wastewater treatment plant customers, as well as the society at large.

Double-digit figures of the operational costs of wastewater plants but also some industries are in sludge disposal. By using the correct chemistry in combination with smart process management technologies, significant cost-efficiencies can be achieved.

While millions of people flock to the beaches and public pools this summer, and cautiously cover themselves in sunscreen to avoid sunburn, still too few ask questions about the quality of the water they plunge into to cool down from the heat.

Around 10–20%% of the operational costs of wastewater plants are in sludge disposal. Have you optimized your sludge handling to the max? Watch our on-demand webinar to find out exactly how.

We all produce it and contribute to the problem, increasingly so due to the global population growth. Poop, feces, waste – call it what you want, you get the drill. How many of us even know where it disappears in the modern society? We need to come up with ways to stop wasting and start reusing. It is the one plentiful resource that is not likely to run out.

Peo Sundstrand, a Process Engineer at Gästrike Vatten’s Duvbacken treatment plant in Gävle, Sweden, has a clear priority. His aim is to make sure the level of suspended solids (SS) in the reject water leaving the sludge dewatering centrifuges is as low as possible.

Ronald van Rossum is an expert in sludge dewatering applications. He’s driven by solving the challenges we face in the water cycle, improving sustainability and efficiency.
