Dewatering
Dewatering is the process of removing water from materials like sludge, soil, or industrial waste. It's a crucial step in many environmental and construction projects where excess water needs to be removed to make materials easier to handle or dispose of. Think of it like wringing out a wet sponge, but on an industrial scale. Companies use various methods including special pumps, filters, and equipment to separate water from solid materials. This process is common in wastewater treatment plants, construction sites, and mining operations. When you see this term in resumes, it usually indicates experience with water treatment equipment and environmental management.
