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...

Introduction: The Clarifier, or Settling Tank, is a crucial component in the sewage treatment process, designed to separate solid sludge from treated water through sedimentation. It ensures that bacterial flocs settle efficiently while preventing turbulence, allowing for the collection of sludge and the discharge of clarified water. Proper operation of the clarifier is essential to maintaining a balanced biological process in the treatment plant, preventing microorganism loss, and ensuring smooth wastewater processing. CLARIFIER/ SETTLING TANK 1 The sewage inlet pipe brings sewage from the aeration tank. 2 The center-feed well takes this incoming sewage and gently releases it in the settling tank, without causing any disturbance or turbulence. 3 The sludge is only slightly heavier than water; so it takes time to sink. It slides down the steeply sloped walls of the tank toward the center of the bottom. 4 The bacterial flocs7 collect here in high concentration. 5 The sludge delivery pipe...

 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 The equalization tank is a crucial component in a Sewage Treatment Plant (STP), serving as the first collection and buffering stage. It regulates the fluctuating inflow of raw sewage from bar screen chambers, oil traps, and grit separators, ensuring a steady and controlled flow to the treatment process. This tank plays a vital role in preventing system overloads during peak hours while maintaining efficient wastewater treatment. Additionally, aeration through coarse bubble diffusers helps in mixing and preventing sedimentation, optimizing the efficiency of the STP. Equalization Tank The sewage from the bar screen chamber and oil, grease and grit trap comes to the equalization tank. The equalization tank is the first collection tank in an STP Its main function is to act as buffer:  To collect the incoming raw sewage that comes at widely fluctuating rates, and pass it on to the rest of the STP at a steady (average) flow rate. During the peak hours, sewage comes at a high...

Introduction Sewage treatment is an essential process designed to remove contaminants from wastewater, household sewage, and industrial effluents. The primary goal is to ensure that the treated water is safe for disposal into the environment or suitable for reuse in various applications. This process involves physical, chemical, and biological methods that collectively help maintain environmental balance and reduce the strain on potable water sources. Proper sewage treatment is crucial to: Prevent water pollution Protect human health Conserve natural resources by reusing treated wastewater Reduce the environmental impact of urbanization and industrialization Stages of Sewage Treatment Sewage treatment consists of three main stages: primary, secondary, and tertiary treatment. Each stage plays a critical role in ensuring the removal of solids, organic matter, and pathogens. 1. Primary Treatment (Solid Separation) Primary treatment is the initial phase where large solids and sediments are...
