Why does coconut shell activated carbon need to be acid washed? What is the acid washing process of coconut shell activated carbon?What are the benefits of coconut shell activated carbon after acid washing?
Acid washing process of coconut shell activated carbon：
1.Pour softened water into the pickling kettle, put in the coconut shell activated carbon that needs to be pickled, select the cleaning mode, remove the floating carbon on the surface of the coconut shell activated carbon, and discharge the black water. Repeat the above process until the softened water discharged from the pickling kettle is clear.
2.Add hydrochloric acid, then put in the pickling material, steam cook, then add clean purified water, and overflow to discharge the black water.
3.Start the centrifuge to rotate at a low speed, open the feed valve, and pass water and activated carbon materials into the centrifuge for dehydration. Then use the water distribution pipe to spray reverse osmosis RO water to rinse the activated carbon, and then dehydrate it.
4.The coconut shell activated carbon is sent to the dryer for drying and then crushed and screened to the required particle size.
Benefits of coconut shell activated carbon pickling:
- Adjusting pH can improve the taste of water
- Pickling can remove impurities, and hydrochloric acid can reduce the content of heavy metals and improve the safety of water purification.
- Reduce ash such as calcium carbonate, remove soluble inorganic salt ash, and degrade TDS concentration.
- Reduce dust on the surface and pores of coconut shell activated carbon, and reduce the amount of black water.
