When it comes to multi-media filtration, garnet stands out as a high-density media. It enhances filtration capabilities, performance and water quality. Garnet sand is chemically inert, widely used as a support layer in multimedia filtration systems. From commercial to industrial systems for wastewater treatment, garnet is a suitable multi-filtration media. At Western Adsorbents & Catalysts, we supply a wide range of garnet grades to be used as an industrial water and wastewater treatment media. In this blog, we explore the role of garnet as a filter media for water filtration systems, highlighting the versatility of garnet.
Why Garnet is Used as a Filter Media for Water & Wastewater Treatment?
Garnet is a naturally occurring almandine mineral with a specific density of (4.0- 4.2), high hardness (6-8 Mohs scale) and subangular grain structure. Due to its unique properties, industries rely on garnet suppliers in India for water and wastewater filtration systems.
Key Properties of Garnet Sand
| Chemical Formula of Garnet | Fe₃Al₂(SiO₄)₃ |
| Specific density | 4 |
| Bulk density | 3 g/cc |
| Hardness | 6-8 Moh scale |
| Effective size | 12-20, 20-40, 30-60, 80 & 120 mesh |
| Uniformity coefficient | ≤ 1.7 |
| Turdibity removal | Up to 10-20 µm particle size |
Due to high density, the garnet settles down at the bottom layer in the multi-media and dual media filter bed. It provides a strong foundation for effective filtration of even suspended particles.
How Does Garnet Work as a Filter Media?
In a multimedia filtration system, different materials like anthracite coal India, activated carbon and garnet are layered according to their density.
Multilayer Filter Bed Arrangement
➤ Activated carbon/Anthracite Coal at the Top Layer: It traps larger particles
➤ Ion Exchange Resin at the Middle Layer: Demineralizes heavy metals
➤ Garnet Filter Media at Bottom Layer: Captures finer particles
This filtration system configuration offers optical filtration, prevents clogging and prolongs run time between backwash cycles. Garnet’s specific gravity and angular grains enhance solid particles retention, ensuring lower turbidity and optical water treatment.
Where is Garnet used as Filter Media?
Garnet’s excellent properties, like high density, hardness and angularity, make it an effective multi filtration media.
➤ Industrial water treatment: Ideal for pre-filtration & post-treatment systems for manufacturing, power plants and refineries.
➤ Municipal water filtration: It ensures efficient removal of turbidity and suspended solids & water treatment plants.
➤ Wastewater treatment plants: Garnet removes finer particles and particulates in WWTPs during the tertiary stage.
➤ Swimming pool filtration: Its excellent compatibility with other filtration media makes it suitable for commercial swimming pools.
➤ Cooling tower and Process Water Filtration: It consistently removes particulate matter from process streams.
