Silica Sand Filter Media
Silica Sand is a naturally occurring material, hard, durable, dense grains, of minimum 98% siliceous material, and free of dust, clay, and micaceous and organic matter.
Sand is washed, dried, and sieved to standard grain sizes that meet or exceed international standards such as AWWA B100 and / or EN12904 – Type 1.
Silica Sand is an inert material, its physical and chemical properties do not change due to environmental conditions; therefore, using Sand as filter medium ensures reliable operation and cost-effective solution. Sand is used in mono or a second layer of dual or multimedia filters, its relative low density good layers separation and higher solid retention within upper layers of filter media.
- We offer both high purity silica sand filter media.
- Acid Solubility is tested in 10% HCl solution for 24 hours.
- Attrition loss is calculated on basis of 100 hours of backwash
Both size ranges 0.4 – 0.8 and 0.5 – 1.0 provides balanced
ENSYAB supply superior quality, low-density (~750 kg/m3), low UC (<1.3) Anthracite filter media beside regular density anthracite.

- EN12904 / AWWA B100 requires media specification either as size range, UC and over/under size or Effective Size and UC.
- The size range (0.4 – 0.8) and (0.5 – 1.0) are mostly chosen for water treatment application as good balance of size, head loss characteristics and expansion at reasonable backwash velocity.
- We offer other sizes on request
