Courses : Forest Ecology Lecturer :Frischa Adellia Semester : 4thSemester, 2022/2023 Session Pressure Filtration Pressure filtration is a separation method that uses pressure to force a liquid through a filter medium, thereby allowing efficient separation of solid-particles or dissolved substances from the liquid. The basic principle of pressure filtration is that the pressure applied to a liquid will force the liquid through the filter media, while larger solid particles or dissolved substances will be trapped in the filter. The applied pressure can come from a variety of sources, including gravitational pressure, air or gas pressure, or mechanical pressure exerted through devices such as pumps. This application of pressure allows the liquid to pass through the filter media more quickly and efficiently compared to gravity filtration or vacuum filtration. Pressure filtration has a wide range of applications in a variety of industries, including pharmaceutical, food and beverage, chemical, and environmental industries. Examples include water purification for drinking water supply, separation of solids from solutions in industrial processes, and filtration of chemical products in production processes. The advantages of pressure filtration include higher separation speeds, better efficiency in separating solid particles or solutes from liquids, and the ability to be used in a wide range of operational conditions. However, equipment maintenance and operating costs as well as selection of appropriate filter media remain important factors to consider in pressure filtration applications. In pressure filtration, there are several important components used in the separation process, including: 1. Filter media: These are porous media that allow liquids to pass through, but retain larger solid-particles or solutes. The filter media can be filter paper, cloth, membrane, or other synthetic material, depending on the application and separation needs. 2. Container or housing: This is a place where the filter media is placed and the liquid to be filtered flows through it. This container is usually made of metal or plastic which is sturdy and resistant to pressure. 3. Pressure applied system: This is a system used to apply pressure to the liquid to be filtered. This can be a pressure pump, gravity, or pressure generated by gas or air applied to the top of the container. 4. Control valve: Used to regulate the flow of liquid entering or leaving the filtration container. This valve is important for optimally regulating pressure and fluid flow speed. 5. Product collector: This is the place where the filtered product is collected after going through the separation process. This collector can be a container, tube, or tank that is suitable for the volume and type of product to be collected. Pressure filtration is used in a variety of industries and applications, such as purifying drinking water, separating solids from solutions in industrial processes, and filtering chemical products in manufacturing processes. Successful application depends on proper filter media selection, optimal pressure settings, and good equipment maintenance. Thus, pressure filtration is an effective and efficient separation method in various operational conditions. In conclusion, pressure filtration is a separation method that uses pressure to force a liquid through a filter medium, allowing efficient separation of solid-particles or dissolved substances from the liquid. The basic principle of this filtration is to apply pressure to the liquid to force the liquid through the filter media, while larger particles or dissolved substances are retained in the filter. The advantages of pressure filtration include high separation speeds, good efficiency in separating solid particles or solutes from liquids, and the ability to be used in a variety of industrial applications. However, successful application depends on proper filter media selection, optimal pressure settings, and good equipment maintenance. Pressure filtration has a variety of applications in industry, including water purification, separation of solids from solutions in industrial processes, and filtration of chemical products in manufacturing processes. Thus, this method is an effective and efficient separation method used in various industries and applications.
