WasteWater Treatment

Wastewater treatment is a process used to clean contaminants from sewage or wastewater, turning it into a treated water that can be safely returned to the water cycle with minimal harm to the environment, or even reused for other purposes, known as water reclamation.

In industries where chemical processes generate vent gases and water residues, these often contain corrosive substances. Using graphite equipment is necessary for various treatment processes like heating, cooling, scrubbing, and stripping.

Disposing of wastewater from industrial plants is a challenging and expensive task. Many refineries, chemical, and petrochemical plants have their own facilities to treat wastewater to meet local and national regulations before releasing it into community treatment plants, rivers, lakes, or oceans. Some industries, like paper and pulp production, are finding ways to recycle water within their plants to address environmental concerns and reduce the need for cleaning and disposal. In cases where municipal sewage treatment plants are not available or cannot handle specific industrial wastewaters effectively, industrial wastewater treatment plants are necessary.

Capturing and eliminating heavy metals in industrial effluent: that is the aim of Capterall®, a wastewater treatment solution developed by Solvay and now owned by Prayon. With this acquisition Prayon can harness a sustainable and innovative technology while also developing a new high-added-value business offering that involves providing its customers with integrated solutions to overcome the water-related environmental challenges they face.
