Fine Sand

0.5–0.8mm Fine Sand The Professional Choice for Superior Water Clarity

Our 0.5–0.8mm Fine Sand is not standard construction sand; it is high-purity silica filter media engineered for high-performance mechanical filtration. The uniform grain size ensures an even flow distribution throughout the filter bed, preventing “channeling” where water bypasses the media without being cleaned.

Key Features & Benefits:

• Precision Filtration: Its 0.5–0.8mm size is the “sweet spot” for trapping microscopic debris, algae, and sediments as small as 20–50 microns.

• Chemical Inertness: Being high-purity silicon dioxide, this sand does not react with chemicals or leach impurities into your water, ensuring the final output is safe and odorless.

• Long Service Life: The high hardness of the quartz grains ensures that the media resists abrasion. This allows for thousands of backwash cycles without significant loss of material or filtration quality.

• Multi-Media Compatibility: This grade is the perfect middle-layer for multi-media filters, often paired with coarse gravel at the bottom and anthracite at the top for advanced turbidity removal.

• Cost-Effective Maintenance: Because the sand is pre-washed and dust-free, it reduces initial rinsing time and minimizes the risk of clogging your underdrain system.

Typical Applications in Sri Lanka:

• Swimming Pool Filtration: Compatible with all major brands of sand filter pumps to keep pool water sparkling and clear.

• Reverse Osmosis (RO) Pre-treatment: Protects expensive RO membranes by removing larger particles that cause premature fouling.

• Drinking Water Purifiers: Used in domestic and municipal gravity or pressure filters to treat groundwater and well water.

• Industrial Wastewater: Helps in the tertiary treatment of industrial effluent before discharge, ensuring environmental compliance.
