Anthracite (40 Kg Per Bag)price Per Kg

Description

Anthracite is a type of hard, high-carbon coal that is commonly used in water treatment systems as a filter media. It plays an important role in mechanical filtration and is especially effective in removing suspended solids from water.

---

🔹 What is Anthracite?

• A naturally occurring form of coal with a high carbon content (around 86–98%)

• Very hard and brittle

• Has a high specific gravity and durability

• Chemically inert and non-toxic

---

🔹 Role of Anthracite in Water Treatment:

---

🔹 Benefits of Using Anthracite:

• High dirt-holding capacity

• Long service life

• Improves filter run time

• Resistant to biological and chemical fouling

• Cost-effective for large-scale filtration

---

🔹 Common Applications:

• Municipal drinking water plants

• Industrial process water

• Wastewater treatment

• Pretreatment for RO systems

• Swimming pool filtration

---

🔹 Specifications (Typical):

• Effective size: 0.6 – 1.6 mm (can vary)

• Uniformity coefficient (UC): <1.7

• Specific gravity: ~1.5

• Hardness (Mohs scale): ~3

  Anthracite is commonly used in pressure and gravity filtration systems, especially as part of multimedia filters in both industrial and municipal water treatment setups.

  Here’s a breakdown of filtration systems that use anthracite:

  ---

  🔹 1. Multimedia Filters (MMF) / Dual Media Filters

  Usage:
  ✔️ Most common system using anthracite
  ✔️ Used for potable, process, and wastewater

  Description:
  Multimedia filters consist of layers of different media with varying densities and sizes. Anthracite, being the least dense, is used as the top layer to capture coarse particles, while finer media like sand or garnet below capture smaller particles.

  Typical Media Configuration (top to bottom):

  • Anthracite (coarse filtration)

  • Sand (intermediate filtration)

  • Garnet (fine filtration)

  Benefits:

  • Improved filtration depth

  • Longer filter runs

  • Better particle removal than single-media filters

  🔹 2. Gravity Sand Filters (e.g., in Water Treatment Plants)

  Usage:
  ✔️ Municipal drinking water plants
  ✔️ Slow or rapid gravity filters

  Description:
  Anthracite may be added as a coarse media layer to increase filtration capacity and reduce clogging. It is especially used in rapid gravity filters for high-flow applications.

  ---

  🔹 3. Pressure Filters

  Usage:
  ✔️ Industrial water treatment
  ✔️ Cooling tower water systems
  ✔️ RO pretreatment

  Description:
  Closed vessels where water is forced through media under pressure. Anthracite is used to remove suspended solids, protecting downstream systems like membranes or ion exchange units.

  ---

  🔹 4. Tertiary and Polishing Filters

  Usage:
  ✔️ Wastewater polishing
  ✔️ Final filtration stage before discharge or reuse

  Description:
  Anthracite helps in the final removal of fine particles, organics, and some trace metals when used with other media.

  ---

  🔹 5. Desalination Pretreatment Systems

  Usage:
  ✔️ RO/NF/UF system pretreatment
  ✔️ Seawater or brackish water treatment

  Purpose:
  Reduce fouling on membranes by filtering out suspended solids, organics, and particulates using anthracite in MMF configurations.
