From Pollutants to Resources: What Can Be Recovered from Industrial Wastewater and Sludge?
Industrial Wastewater Is More Than Waste Traditional industrial wastewater treatment follows a straightforward principle: remove pollutants and ensure that the treated water meets discharge requirements. But there is another question worth asking: Where do the pollutants go after they are remove...Read more -
From Waste to Resource: How Sludge Management Is Driving the Future of Wastewater Treatment
For decades, sewage sludge has been considered a by-product of wastewater treatment – something that requires further treatment, transportation, and disposal. However, with growing challenges such as water scarcity, increasing energy demand, and stricter environmental regulations, the role ...Read more -
From Screw Presses to Multi-Disc Screw Presses: How One Sludge Dewatering Technology Has Evolved with the Industry
Today, multi-disc screw presses have become a common choice for sludge dewatering in municipal wastewater treatment plants and industrial wastewater projects around the world. Compared with traditional belt filter presses and centrifuges, they generally require less installation space, offer a hi...Read more -
Why Is Sludge Dewatering Necessary? Understanding Its Role in Sludge Treatment
Why Is Sludge Dewatering Necessary? Understanding Its Role in Sludge Treatment Sludge dewatering is a key stage in sludge treatment. Rather than removing all moisture, its primary purpose is to reduce the water content of sludge, making it easier and more economical to transport, store, and dispo...Read more -
Why the wastewater treatment industry is starting to refocus on “system stability”?
For a long time, the wastewater treatment industry focused primarily on equipment performance. How much sludge a dewatering unit can handle, how low the cake moisture can go, and how advanced the equipment is were often the key points in project discussions. But in recent years, the focus has bee...Read more -
Sludge Treatment Is Entering the Era of Resource Recovery
In 2022, California faced another severe drought. At the same time, some wastewater treatment plants were still transporting large volumes of high-moisture sludge every day. The contradiction became increasingly obvious: while water and energy costs continued to rise, huge amounts of water were s...Read more -
World Bank to Water Companies: Time to Upgrade Your Game
“The operational efficiency of a wastewater treatment plant may matter more to a city’s economic future than a large reservoir.” — In April, the World Bank, together with several multilateral financial institutions, launched a ten-year action plan called “Water Forward....Read more -
Sludge Cake Moisture Content: Is Lower Always Better? | Dewatering System Guide
In many sludge dewatering projects, achieving the lowest possible cake moisture content is often treated as a primary goal. Whether during equipment selection or daily operation, moisture content is frequently used as the key indicator of how well a sludge dewatering system performs. In practice,...Read more -
How to Choose the Right Sludge Dewatering System for Your Plant？
In wastewater treatment, sludge handling is often underestimated, yet it has a direct impact on operating costs and overall plant performance. For both municipal and industrial facilities, choosing the right sludge dewatering system affects not only treatment efficiency, but also downstream trans...Read more -
The Impact of PFAS on Sludge Dewatering: Changing Disposal Pathways and System Requirements
1. PFAS and Their Behaviour in Wastewater Treatment Per- and polyfluoroalkyl substances (PFAS) are a large group of synthetic chemicals widely used in industrial and consumer applications. Due to the strength of the carbon–fluorine bond, they are highly persistent in the environment and are ofte...Read more -
World Water Day: Rethinking Water, Gender and What We Overlook
Water and Gender: A Perspective Often Missed The theme of World Water Day 2026, Water and Gender, draws attention to a perspective that is often overlooked. In the broader landscape of water management, different groups take on different roles – and face different realities. In many water-...Read more -
Sludge Dewatering: From Environmental Cost to Operational Value
In many industrial operations, sludge treatment has long been regarded as a necessary environmental expense – something that does not generate output, yet continuously consumes budget and management effort. This perception is beginning to shift. As production scales expand and operating rh...Read more
