Wastewater treatment plants have become a focal point in protecting our future water supply by reducing the toxic impacts of wastewater and its use in daily life. Several wastewater treatment procedures use physical and chemical…

The quality of wastewater effluents causes degradation of receiving water bodies such as lakes, rivers and streams. Chemical and biological treatment are the two basic techniques for removing contaminants from wastewater influents,…

Flotation Flotation may be used instead of the normal clarification by solids-downward-flow sedimentation basins as well as thickening the sludge instead of the normal sludge gravity thickening. Water containing solids is clarified…

Wastewater treatment is the process of restoring desirable quality to water that has been utilized and/or contaminated by humans or nature. Chemical, biological, or physical processes, or a combination of these, may be used in treatment.…

Heavy metal pollution in wastewater from industrial processes is a major environmental concern. Untreated wastewater with heavy metals discharged into the environment can contaminate aquatic life and crops. Heavy metals can…

Sludge Thickening process Thickening of sludge is a process to increase its solids concentration and decrease its volume by removing some of the free water. The resulting substance is still fluid. Thickening is employed before…

Every drop of water is precious. Unfortunately, 30–50% of water is misplaced thru aging infrastructure. While misplaced water equals misplaced sales to the water carrier supplier. Water is misplaced thru leaks and cracks in pipes and…

The aeration process is the process by which water and air come into close contact to remove dissolved gases (such as carbon dioxide) and oxidize dissolved metals such as iron, hydrogen Sulphide and volatile organic compounds (VOCs).…

When wastewater is treated using various mechanical, biological, and physicochemical methods to remove organic and inorganic pollutants to levels required by the permitting authority, the sludge produced will also vary in quantity and…

Water innovation is critical to the development of a better future. New technology allows for advancements, but contrary to popular belief, we now have the generation required to address the most serious water challenges. To increase…
