As urban populations swell around the globe, an overlooked byproduct of our modern sewage systems is accumulating at an astonishing pace – wastewater sludge. This problematic solid waste is highly nutrient-rich yet challenging to manage sustainably. But innovative resource recovery techniques are now transforming sludge from an environmental liability into a circular economic asset supplying […]

Dewatering is an essential process in wastewater treatment, which involves the removal of water from solid waste or soil. By reducing the volume of sludge, dewatering systems enable more efficient waste handling and disposal. This process is not only crucial for the effective management of wastewater but also has significant cost implications, as transporting and […]

Dissolved air flotation (DAF) is a water treatment process that clarifies wastewater by the removal of suspended matter such as oil, grease, or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank or basin. The released air […]
