Three-phase transformers operate using the same principles: passing an alternating current through a primary winding causes an alternating magnetic flux in the core, which induces an alternating voltage in the secondary winding. In three-phase transformers there are three primary windings and three secondary windings.

Activated Sludge Treatment Process – Concept and System Design Dr. Akshey Bhargava, Professor (M.tech, Ph.D., LLB) Department of Civil Engineering Global Institute of Engineering and Technology, Hyderabad, India _ Abstract - Activated Sludge Treatment is a biological wastewater treatment process which speeds up waste decomposition

SBRs are a variation of the activated sludge process. They differ from activated-sludge plants because they combine all of the treatment steps and processes into a single basin, or tank, whereas conventional facilities rely on multiple basins. According to a 1999 U.S. EPA report, an SBR is no more than an activated-sludge plant that operates in .

The activated sludge process Most wastewater treatment plants are using the activated sludge process. The heart of such a process mainly consists of an aeration tank, a sedimentation tank or clari-fier and a sludge recycle line. In the aeration tank wastewater and activated sludge are mixed in the presence of dissolved oxygen.
