treatment, and the problem of how to get rid of sludge produced by the treatments, whereas the electrochemical remediation methods can be used as an alternative technology for the purification of wastewater contaminated with toxicants. Electrolytic wastewater treatment is rarely used in comparison to chemical treatment.

How Wastewater Treatment WorksThe Basics - US EPA

Wastewater Treatment Works... The Basics O ne of the most common forms of pollution control in the United States is wastewater treatment. The country has a vast system of collection sewers, pumping stations, and treatment plants. Sewers collect the wastewater from homes, businesses, and many industries, and deliver it to plants for treatment.

Electrolytic treatment of wastewater presents an innovative technology in which a sacrificial metal anode and cathode produce electrically active coagulants and tiny bubbles of hydrogen and oxygen in water.

Industrial wastewater treatment: Current trends, bottlenecks

The residue that accumulates in sewage treatment plants is called sludge (or biosolids). Sewage sludge is the solid, semisolid, or slurry residual material that is produced as a by-product of wastewater treatment processes. This residue is commonly classified as primary and secondary sludge. Primary sludge is generated from chemical precipitation, sedimentation, and other primary processes
