This process is based on a physical separation process and includes the following fundamental principles:
Feed Water Inlet: Polluted water is transferred to the filter through a feeding system for the filtration process.
Filter Media: Multimedia filtration systems use various types of filter media with different sizes and characteristics. Sequential filters or mixed filter beds, usually arranged from bottom to top, are commonly used. Media types can include sand, gravel, anthracite, and other materials.
Particle Capture: As the dirty water moves from the top to the bottom, particles within the filter media become trapped between the media grains. Particles concentrate at the top of the filter during this stage.
Backwashing and Cleaning: Multimedia filtration systems are regularly backwashed to clean accumulated particles from the filter media. Backwashing involves reversing the direction of the water flow and dislodging particles between the media grains.
Clean Water Outlet: After purification, clean water is extracted from the filtration unit and stored or distributed for use. Purified water provides safe and high-quality water for drinking, industrial processes, or other applications.
Multimedia Sand Filters and Water Treatment Technology
Multimedia sand filters are an essential filtration method in water treatment processes for effectively removing suspended solids and colloidal particles. This technology is designed to clean water sources and improve water quality by removing sediment and particles. Multimedia sand filters utilize different filtration media layers of quartz and sand to achieve excellent filtration performance.
Filter Media and Operating Principle:
Multimedia sand filters consist of layers of quartz with different sizes and densities. These layers combine with their specific weights to capture particles in the water. The selection of filter media is carefully made according to water characteristics and purification goals. These filters are also designed to capture iron ions in water by reducing filtration rates and modifying the media.
Automation and Backwashing:
Multimedia sand filters can be equipped with automation valves to perform backwashing processes on a time-dependent basis. Backwashing is used to clean accumulated particles in the filter media. This process ensures the continuous efficiency of the filtration unit and minimizes maintenance requirements.
Applications and Advantages:
Multimedia sand filters are effectively used in a range of applications. Sand filtration before reverse osmosis (RO) systems mainly protects the RO system and prolongs membrane lifespan. These filters also serve as essential components of water treatment systems, safeguarding subsequent treatment equipment.
Different tank options are available depending on the intended use, including composite-bodied vessels, carbon steel or stainless steel tanks. Multimedia sand filters have provided excellent results across a wide range of flow rates, from the smallest to the highest. One significant advantage of these filters is that they only require water for the backwashing process, making them highly cost-effective in terms of operation.
Multimedia sand filters are a powerful water treatment technology that effectively removes particles, sediment, and suspended solids from water. Their versatility in different applications and capacities makes them suitable for a broad spectrum of water treatment needs. Additionally, their automation valves ensure operational efficiency while minimizing maintenance requirements, making them a preferred choice.
