Quartz sand filter media has become one of the most essential and widely used materials in modern water treatment. Whether it’s a municipal WTP, reverse osmosis pretreatment, industrial filtration line, ETP/STP system, swimming pool, or cooling tower, quartz sand stands out for its exceptional filtration performance, durability, purity, and long service life.
As global water infrastructure continues to grow, the demand for export-quality quartz sand filter media is increasing rapidly. This guide explains everything a buyer, engineer, or procurement team needs to know about quartz sand including its specifications, grades, sizes, industrial uses, international standards, and how to source the highest-quality product for global projects.
We will also discuss why Starke has emerged as a trusted, dependable supplier of premium quartz sand filter media to buyers across the Middle East, Africa, Europe, and Asia-Pacific.
What Is Quartz Sand Filter Media?
Quartz sand filter media is a high-purity silica-based sand that has been:
washed
dried
graded
sieved
quality-checked
…to meet specific filtration requirements.
This sand is extremely effective in removing:
suspended solids
TSS (Total Suspended Solids)
turbidity
silt
clay particles
organic matter
iron & manganese (when used before catalytic media)
Its natural hardness, high-silica composition, and low impurities make it ideal for consistent and reliable filtration performance.
Because of its purity and stability, quartz sand is widely used as a drinking water filtration media and complies with international standards such as:
AWWA B100
EN 12904
IS 8419
These certifications ensure the sand is suitable for drinking water processing, municipal plants, and critical water systems.
Types of Quartz Sand Filter Media
Quartz sand comes in multiple grades and purity levels, depending on the application. Here are the primary types:
1️⃣ High-Purity Quartz Sand
Used in:
drinking water filtration
RO/UF pretreatment
industrial polishing filters
Known for:
high silica content
extremely low impurities
excellent clarity improvement
2️⃣ Washed Quartz Sand Filter Media
This is quartz sand washed thoroughly to remove:
clay
dust
fines
unwanted contaminants
Washed quartz sand is preferred in:
WTP rapid gravity filters
tertiary treatment plants
aquaculture systems
3️⃣ Dried Quartz Sand Filter Media
Dried quartz sand offers:
precise particle sizes
low moisture
easy handling
stable bulk density
Applications include industries where grading accuracy is crucial.
4️⃣ Natural Quartz Sand
Natural quartz sand offers a balance of:
high mechanical strength
optimal hardness
chemical stability
It is widely used in large municipal and industrial systems.
5️⃣ Angular and Round-Grain Quartz Sands
Angular quartz sand provides better depth filtration and is used in multimedia filters.
Round-grain quartz sand is ideal for:
swimming pools
high-flow-rate filters
irrigation systems
Properties Buyers Must Check Before Purchasing Quartz Sand
When buying quartz sand filter media, it is important to evaluate the following parameters:
1. Effective Size (ES)
Typical ES values for quartz sand include:
0.5–1.0 mm
0.5–1.2 mm
1.0–2.0 mm
Correct ES ensures optimum filtration speed and turbidity removal.
2. Uniformity Coefficient (UC)
A low UC ensures:
uniform water distribution
reduced channeling
superior filter runs
Export-grade quartz sand usually has UC < 1.7.
3. Purity & Mineral Composition
High-quality quartz sand should contain:
high silica (SiO₂ ≥ 95–99%)
low clay
negligible organic matter
low iron
This ensures consistent performance and prevents fouling.
4. Bulk Density
Quartz sand typically ranges between:
1400–1600 kg/m³
Bulk density is crucial for designing filter beds and calculating loading quantities.
5. Hardness
Quartz sand has a high hardness level (6–7 Mohs), making it resistant to:
abrasion
breakdown
compaction
This increases media lifespan significantly.
Applications of Quartz Sand Filter Media Across Industries
Quartz sand is one of the few filtration media used in almost every water treatment system. Below are the most common applications:
1️⃣ Municipal Water Treatment Plants
Quartz sand is used in:
rapid sand filters
gravity filters
polishing units
These systems require quartz sand because of its excellent capability to remove suspended solids and turbidity.
2️⃣ Desalination & RO Pretreatment
Quartz sand helps protect:
RO membranes
UF/MF systems
It removes fine particles that would otherwise foul membranes.
3️⃣ Industrial Filtration
Industries such as:
power plants
refineries
mining
chemical processing
pharmaceuticals
…use quartz sand to ensure high-quality process water.
4️⃣ ETP & STP
Quartz sand is used for tertiary polishing, helping meet environmental discharge norms.
5️⃣ Swimming Pool Filtration
Quartz sand is preferred for swimming pools because it offers:
better clarity
longer filter runs
easy backwashing
6️⃣ Cooling Tower Water Treatment
Quartz sand helps reduce solids load, improving tower efficiency.
7️⃣ Aquaculture & Irrigation
Quartz sand provides:
reliable biological filtration
stable hydraulic performance
…making it suitable for aquaculture tanks and large irrigation systems.
Quartz Sand in Multimedia & Dual-Media Filters
Quartz sand is commonly paired with:
anthracite
garnet
gravel
…to create highly efficient multimedia filter beds.
Advantages include:
greater filtration depth
reduced turbidity
higher flow rates
longer filter cycles
Multimedia filters are widely used in large water treatment plants, desalination units, and industrial facilities.
