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, however, this assumption does not always hold true. In most cases, pushing for lower moisture content does not automatically lead to a better outcome, and a more balanced target range is usually 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 transport, disposal costs, and environmental compliance. The challenge is that sludge characteristics vary widely. There is no one-size-fits-all sludge dewatering equipment. A poor selection can lead to...
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 often referred to as “forever chemicals”. In wastewater treatment processes, PFAS are difficult to remove. Conventional treatment technologies show limited effectiveness in degrading or eliminating these...
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-scarce regions, the responsibility of collecting water still falls largely on women. Hours are spent each day walking to and from water sources - time that could otherwise be used for education, work or rest....
Three Key Parameters for Equipment Selection
In the process of selecting dewatering equipment, throughput, feed sludge concentration, and dry solids load are usually the primary parameters discussed. Throughput:the total volume of sludge entering the dewatering unit per hour. Feed sludge concentration:the proportion of solids in the sludge fed into the dewatering unit. Dry solids load:the mass of dry solids obtained by theoretically removing all water from the discharged sludge. In theory, these three parameters can be...
