NEREDA®: an emerging technology for sewage treatment

Abstract

Stringent environmental regulations and severe water pollution has divert the attention of stakeholders, water boards and ministries dealing with the water resources and environment to explore new technologies to make rivers and water bodies free from pollution. Recently an aerobic granular biomass based technology; named NEREDA® has been gaining wide publicity around the globe. It has several advantages such as less power requirement, no need of chemicals and its compactness due to high mixed liquor suspended solids, significantly less capital and operational costs. NEREDA® can be regarded as an alternative to conventional aerobic technology for sewage and industrial wastewater treatment. Recently NEREDA® technology has been installed at sewage treatment plants in Europe, South Africa and few are under pipeline in parts of Latin America, Israel and India.
