IBC Water stock a comprehensive range of water treatment media and resin. The one stop shop for media top-up, replacement or new installation.

Terminology


  • ATTRITION LOSS - Loss of media due to wear by friction during backwash, regeneration or service.
  • ASH CONTENT - Number reflects the purity of the activated carbon. Ash is the inorganic residue left after heating the raw material. In general, a low percentage is desirable.
  • METHYLENE BLUE - The number of milligrams of methylene blue that can be absorbed by 1 gram of carbon. It measures the macroporous volume of carbon and generally excluding the micropores.

  • FRIABILITY - Calculated based on the useable quantity (having same effective size) of a substance after grinding.
  • EFFECTIVE SIZE - A measure of the size of a media defined as the diameter of a specific particle in a batch (of lot) which has 10% smaller and 90% larger particles.
  • IODINE* - Use to correlate the ability of activated carbon to absorb low molecular weight and small organic substance. It is the milligram of iodine molecule that can be absorbed by 1 gram carbon.
    *(Iodine is used because of it's small molecular size).
  • ACID SOLUBILITY - The loss of weight of media after being in contact with the acid. The loss must be less than 2%.
  • SPECIFIC GRAVITY - Ratio of the weight of a specific volume of a substance compared to the weight of the same volume of water at 4 degrees Celsius.
  • UNIFORM COEFFICIENT - The degree of variation in the size of the grains that constitute granular material. The coefficient is 1 if the grains size are all the same and increases with greater variation.

Product Particulars


 Products  Physical Properties
 ACTIVATED CARBON

 Used in a variety of water treatment applications requiring the removal of taste, chlorine, odour and colour. Base materials available from coconut shells, coals or others. Granular activated carbon absorbs chlorine, organics, bluegreen algae toxins and has a nominal capacity and the carbon will need replacing when it's removal capacity diminishes.
