Sewage Treatment Plant - Filter Feed Pumps Types and Operation And Maintenance Considerations

Introduction: Filter Feed Pumps are essential components in industrial water treatment systems, facilitating the movement of water through filtration stages to enhance its quality. These pumps draw clarified water and direct it through the Pressure Sand Filter (PSF) and Activated Carbon Filter (ACF), which work together to remove solid impurities, organic matter, and undesirable odors. By ensuring consistent water flow and pressure, Filter Feed Pumps play a crucial role in maintaining efficient filtration processes. FILTER FEED PUMPS Filter Feed Pumps are used to draw water from the clarified water sump and pass it through the Pressure Sand Filter (PSF) and Activated Carbon Filter (ACF), which are installed in series to improve water quality. PRESSURE SAND FILTER (PSF) Working Principle: The upper layers of sand perform the actual filtration function, while gravel layers provide physical support. Specialized sand with a specific particle size is used to trap solid impurities present in...

Operation and Maintenance of Diesel Generators – Part 5: Understanding Cooling System of DG, Its Working Principle and Key Components

  Part 5: Understanding Cooling System of DG, Its Working Principle and Key Components A diesel generator (DG) set relies on an efficient cooling system to maintain optimal engine temperature and prevent overheating. As the diesel engine converts fuel into mechanical energy, a significant portion of the energy is lost as heat, which needs to be dissipated to avoid damaging the engine. Since the engine generates heat at high rates, it is crucial that the cooling system operates efficiently to absorb, circulate, and expel the excess heat. The cooling system in a diesel generator is designed to ensure the engine operates within an optimal temperature range. If the system is not functioning correctly, the engine could overheat, resulting in irreparable damage, reduced efficiency, and shortened engine life. In this fifth part of the Diesel Generator Insights Series, we will explore the cooling system, its essential components, and how proper maintenance can improve engine efficiency, re...
