reoveepuhastisse

Reoveepuhastisse, often translated as wastewater treatment plant, is a facility designed to remove contaminants from domestic sewage and industrial wastewater. These plants are crucial for public health and environmental protection, ensuring that water returned to the environment meets certain quality standards. The process typically involves several stages. Preliminary treatment aims to remove large solids and grit through screening and grit removal. Primary treatment then involves sedimentation, where heavier organic solids settle to the bottom as sludge, and lighter materials float to the surface.

Secondary treatment is the biological stage, where microorganisms are used to break down dissolved and suspended organic matter. This is often achieved through activated sludge processes or trickling filters. Tertiary treatment, or advanced treatment, is employed when higher levels of purification are required. This can include nutrient removal (nitrogen and phosphorus), disinfection (using chlorine, UV light, or ozone), and filtration to remove remaining suspended solids. Sludge generated throughout the treatment process also requires further treatment, often through digestion, dewatering, and disposal or reuse, for example, as fertilizer. The specific technologies and configurations of reoveepuhastisse vary depending on the volume and type of wastewater treated, as well as local regulations and environmental goals.
