What Is Activated Charcoal For Acid Washing？
Acid washed activated carbon is made of high quality anthracite or coconut shell as raw material, after a series of craft refined granular activated carbon processing, which the overall floating powdered activated carbon is much lower, the water out of the cleaner.
Ideal for many liquid phase applications, acid-washed granular activated carbon is designed for the purification of aqueous and organic liquids requiring low ash and leachate content.
The main purpose of the acid washing process is to remove inorganic salts and heavy metal compounds from the activated carbon, reduce the heavy metal content, adjust the pH value to improve the taste of the water and reduce dust on the surface layer of the activated carbon and in the pores, thus reducing the amount of blackened water and ensuring the hygiene and safety of the drinking water.
Types of Activated Carbon for Acid Washing
Coconut Shell Activated Charcoal For Acid Washing
Coconut shell activated carbon for acid washing is a high density activated carbon made from high quality coconut shells that have been pickled to remove ash. It is suitable for drinking water and industrial water purification treatment, and can effectively remove free chlorine, heavy metals and organic matter.
| Indicator | Parameter |
|---|---|
| Raw materials | Coconut shell |
| Iodine value | 900-1200 mg/g |
| Ash content | ≤5% |
| Hardness | ≥98% |
| pH | 6-8 |
Activated Charcoal Based Carbon For Acid Washing
Coal-based activated carbon for acid washing is manufactured from high quality anthracite as raw material through a series of processes such as carbonization, activation and pickling. It has the advantages of lower heavy metal content, low ash content, improved pH value and lower black water production. It is widely used in water treatment, air purification, food processing, pharmaceutical and other fields.
| Indicator | Parameter |
|---|---|
| Raw materials | Coal |
| Iodine value | 900-1050 mg/g |
| Ash content | ≤18% |
| Hardness | ≥95% |
| pH | 6-8 |
