Lignite Base Carbon - Urbans Aqua

Lignite Base Activated Carbon Overview

Lignite coal, “often referred to as brown coal, is a soft brown combustible sedimentary rock formed from naturally compressed peat.” (Wikipedia) It is used as a base product for the manufacture of granular activated carbon (GAC). Compared to coal and coconut base carbons, it lighter in weight (lbs. per ft3), lower in iodine number and higher in molasses number.

Benefits & Advantages

Lignite base GAC pores are large making it useful for the reduction of similarly sized contaminants such as color pigments. Activated carbon adsorbs contaminants (adsorbates). The adsorbates stick to the pore; they are not absorbed into the carbon.

Advantages

Large pore size/structure
Competitively priced
pH Stable
Higher iodine number when compared to other lignite base carbon types
Lignite base activated carbon may be used in residential applications and should be certified to have no residual metals such as arsenic.

Disadvantages

Calgon HPC Super HD

Urbans Aqua stocks supplies Calgon’s “HPC Super HD” acid washed lignite base carbon. Calgon’s HPC Super HD is used where pH stability is required – such as Kidney Dialysis.
- Calgon HPC Super HD complies with the requirements for activated carbon as defined by the Food Chemicals Codex (FCC) (Latest Edition) published by the US Pharmacopeia.
- It is produced under the supervision of the Islamic Food and Nutrition Council of America (IFANCA) and the Kashruth Division of the Orthodox Union for Kosher certification.
- Certified to NSF/ANSI 61.
Calgon HPC Super HD can be used to remove color bodies like tannic based color as post treatment to tannin removal systems. Doctor Frog suggests reviewing the tannin removal application before using HPS Super HD.
