AWWA B100: Why This Standard Matters in Water Filtration Media Selection

AWWA B100: The Standard Behind Reliable Filter Media in Water Treatment

In water treatment, consistency, safety, and performance of filter media are non-negotiable. Whether treating drinking water or industrial wastewater, the materials inside your filtration system dictate its effectiveness. That’s where the AWWA B100 standard plays a vital role.

At Starke Aquacare Technologies, we prioritize supplying filter media that strictly comply with AWWA B100 to ensure safe, durable, and high-efficiency filtration for municipal, residential, and industrial applications.

What Is AWWA B100?

AWWA B100 is a standard published by the American Water Works Association, specifying the physical, chemical, and performance criteria for granular filter media such as sand, zeolite, anthracite, and more. It provides a quality benchmark for filtration materials used in water treatment systems worldwide.

What Filter Media Types Are Covered?

The AWWA B100 standard applies to:

  • Silica Sand

  • Gravel

  • Zeolite

  • Anthracite

  • Garnet

  • Multimedia filter blends

These are commonly used in:

  • Municipal treatment plants

  • Industrial ETP/STP systems

  • Pressure sand filters

  • Multimedia filtration vessels

 

Key AWWA B100 Specifications & Why They Matter

Here’s what makes AWWA B100-compliant media more reliable:

1. Particle Size Distribution

  • Ensures uniform filtration

  • Reduces pressure drops and uneven flow

  • Prevents early clogging or media migration

2. Shape and Roundness

  • Prefers angular/sub-angular particles

  • Sharp edges trap particles more effectively

  • Enhances durability under backwash cycles

3. Specific Gravity (3.5–4.0 range)

  • Ensures media stays in place under flow

  • Critical in multi-media layering

4. Mohs Hardness (7.5–8)

  • High resistance to physical and chemical wear

  • Extends filter media lifespan

5. Chemical Composition

  • Composed of stable oxides like SiO₂, Al₂O₃, Fe₂O₃

  • Must be free from toxic impurities and heavy metals

6. Uniformity Coefficient (UC < 1.5 preferred)

  • Indicates tight particle size range

  • Improves predictability in filtration and backwash

7. Water Content

  • Must be controlled to avoid clumping or flow restriction

  • Affects transport, installation, and media performance

8. Toxicity

  • Media must not leach contaminants into treated water

  • Especially critical for drinking water applications

9. Resistance to Chemical Attack

  • Compatible with common disinfectants like chlorine and alum

  • Prevents breakdown in harsh conditions
