Sand Filter – Advanced Filtration System for Clean and Clear Water
The Sand Filter is one of the most effective and reliable water filtration systems used for removing suspended particles, turbidity, dirt, and other impurities from water. Designed with precision and durability, it provides high-quality filtration for both industrial and domestic applications.
This system uses multiple layers of specially graded sand and gravel as the filtering medium. As water passes through the sand bed, suspended solids and fine impurities are trapped, allowing clean, clear, and safe water to pass through. The result is consistently purified water suitable for various uses — from drinking and irrigation to industrial process water and swimming pools.
Built with corrosion-resistant materials such as FRP (Fiberglass Reinforced Plastic), mild steel with epoxy coating, or stainless steel, the sand filter offers excellent strength, longevity, and minimal maintenance requirements.
The Sand Filter is ideal for water treatment plants, residential buildings, industrial systems, swimming pools, and irrigation projects, making it a versatile and cost-effective filtration solution.
Working Principle:
The Sand Filter operates on the depth filtration principle, where water is evenly distributed across the top of the sand bed and flows downward through multiple layers of sand and gravel. As the water passes through the filter media, suspended solids and impurities are trapped within the pores of the sand particles.
Clean water then exits through the bottom collector system and is stored or sent for further treatment. When the filter becomes clogged with accumulated dirt, a backwashing process is initiated — water is reversed upward through the filter, loosening and removing trapped particles, and flushing them out of the system.
This simple yet highly effective mechanism ensures consistent filtration performance, long service life, and easy operation.
Key Features:

Applications:
The Sand Filter is widely used in a variety of applications, including:
Water Treatment Plants – For primary filtration before softening or RO systems.
Swimming Pools – To maintain crystal-clear pool water by removing suspended matter.
Industrial Water Systems – For cooling towers, process water, and equipment protection.
Drinking Water Systems – physical impurities to produce clean potable water.
Irrigation and Agriculture – Protects sprinkler and drip irrigation systems from clogging.
Rainwater Harvesting – Filters collected rainwater for safe storage and reuse.
Municipal Water Supply – Used in large-scale water purification systems.
Advantages:
Simple design, easy installation, and user-friendly operation.
Efficient removal of suspended solids and turbidity.
Long-lasting FRP or stainless steel construction ensures durability.
Easy backwash mechanism for cleaning and reusability.
Consistent water quality output even with high turbidity feed.
Cost-effective with low power and maintenance requirements.
Available in various sizes and flow capacities for any application.
Environmentally friendly – no chemical consumption required for filtration.
Technical Working Process:
Inlet Phase: Raw water enters through the top or side inlet.
Filtration Phase: Water passes through layers of graded sand and gravel that trap fine and coarse impurities.
Outlet Phase: Clear water is collected from the bottom and sent for storage or further use.
Backwash Phase: Reverse flow of water cleans the filter media and restores efficiency.
