Water Treatment
Sand and gravel play a crucial role in the water filtration process, which is essential for purifying and treating water to make it safe and suitable for use.
They are commonly used in various water filters to remove impurities and small particles from water.
What Are the Specifications of Filter Sand?
- Grain Size: The ideal Filter Sand grain size ranges between 0.6 mm and 1.2 mm. This size is optimal for allowing water to flow through without clogging the filter.
- Purity: Filter sand must be clean and free from pollutants, impurities and organic matter. The silica content in the sand should exceed 95%.
- Shape: Filter Sand grains should be round or semi-round in shape, as this allows for better water flow during filtration.
What Are the Specifications of Filter Gravel?
- Grain Size: The optimal gravel grain size is between 1 mm and 2 mm. This allows for effective water flow without causing any blockage in the filter system.
- Purity: Gravel should be free of impurities and organic materials that could hinder the filtration process.
- Density: The specific gravity of the gravel should be lower than that of the Filter Sand to support multi-layer filtration systems.
Applications of Filter Sand and Gravel
- Filter Sand Used in sand filters to remove fine particles and impurities from water.
- Filter Gravel Used in gravel filters to trap larger particles and contaminants.
- Multi-layer Filters Sand and gravel can be used together in multi-media filters to eliminate impurities of various sizes.
Benefits of Using Filter Sand and Gravel
They offer multiple advantages, including:
- Efficient removal of fine and large impurities from water.
- Improved water quality and overall treatment performance.
- Reduced risk of waterborne diseases.
- Extended lifespan of filtration systems.
- Support for regular maintenance of filters.
How Is Routine Maintenance of Filter Sand Performed?
- Cleaning the filters to remove trapped impurities and particles.
- Refilling filters with sand and gravel as needed.
- Testing water quality to ensure it meets health and safety standards.
