 Introduction: The Aeration Tank is the core of the sewage treatment process, where biological treatment takes place using microorganisms. This tank maintains a high population of microbes that break down organic matter, forming a mixture known as Mixed Liquor Suspended Solids (MLSS). Through continuous aeration and controlled microbial activity, the tank ensures efficient wastewater treatment before the process moves to the clarifier for further purification. AERATION TANK The Aeration tank is at the heart of the treatment system. The bulk of the treatment is provided here, employing microbes/bacteria for the process.  The main function of the Aeration tank is to maintain a high population level of microbes. This mixture is called MLSS (Mixed Liquor Suspended Solids). The mixed liquor is passed on to the clarifier tank, where the microbes are made to settle at the bottom.  The settled microbes are recycled back to the aeration tank. Thus they are retained for a long peri...

  Introduction: Transformers contain several critical components that ensure their efficient operation, protection, and longevity. Among these, the conservator, breather, explosion vent, oil temperature relay, oil drain valve, fins, level indicator, and Buchholz relay play vital roles in regulating oil levels, preventing faults, monitoring temperature, and ensuring safety. These elements help maintain the transformer's health by addressing oil expansion, air moisture absorption, pressure regulation, and fault detection. Understanding these components is essential for effective operation, maintenance, and fault prevention in transformers. CONSERVATOR:  This is mounted on top of the oil tank. This should have oil two third of its volume and the remaining filled with air. The conservator is used to accommodate the expanded volume of the transformer oil when ever the oil gets heated up owing to loading of the transformer. Also when the oil cools down, the oil from the conservator ...
