Feasibility of Paddle Wheel Aerator in Wastewater Treatment

Abstract

Paddlewheel aerators are generally used for aquaculture but it can be used in multiple fields. It is still up for debate whether paddle wheel aerators have the ability to treat wastewater, with particular attention to their energy efficiency, mechanical simplicity, and flexibility. Originally designed for aquaculture, paddle wheel aerators have gained popularity in wastewater treatment because of their efficiency and inexpensive cost in shallow water settings. Paddlewheel aerators may be appropriate in decentralized, semi-urban, and small-scale operations, according to the article, which discusses important performance measures such as OTE, energy consumption, and the environment. Applications covered include wastewater treatment in homes, businesses, and municipalities, in addition to various systems including those with mild BOD levels. Limited penetration depths in aquatic bodies, clogging issues in wastewater with high solid content, and maintenance issues in contaminated locations are among the current issues. Technological improvements such as variable-speed motors, solar-powered systems, and hybrid aeration approaches are advised to enhance performance. The study concludes that although paddle wheel aerators provide economical, environmentally friendly, and effective solutions, new developments are needed to get over operating restrictions and increase scalability.
