- Softened water is mixed with an acid solution and passed into the pool through a pipe, which is inserted into a hole at the bottom of the pool.
- By controlling the concentration of the acid solution and the pickling time and temperature, the ash, metal ions and other impurities in the activated carbon are further removed.
- The activated carbon is first repeatedly pickled in this pool, and the number of pickling times is determined by the ash and heavy metal requirements.
- After acid washing, alkaline washing and repeated water washing are carried out in this container to ensure that there is no residue.
- The used water enters the water treatment system and is recycled after treatment.
- This is the drying workshop, where the activated carbon after water washing is finally transported here through a pipe for drying.
We use a segmented drying furnace, and the temperature of each section is different. Through temperature control at different stages, the moisture inside and outside the activated carbon is guaranteed to be the same.
- After acid washing, the activated carbon has very low ash content, whether it is internal ash or external ash. It can be seen that it is very clean.
