**2.4 Fly ash/Asphaltite shale char composite**

This compost is especially sorbent used waste water treatment. The fly ash compost granules use as hazardous industrial waste waters and the sorbent types and desirable properties of activated and cleaned sorbents in the experiments are given in **Table 7** and chemistry are given in **Table 8** for geothermal waters used in neutralization (**Table 9**).

Material to be used as powder is packed distributed in tube bed permeable granule grain size, basic as absorption capacity by the cat should be accepted. High absorption capacity having fly ash should avoid digestion waste waters passed through cavities. The grain size distribution of sorbent granules is important and between 1 and 6 mm. The sorbent beds are rounded surfaces not to create dust mass transport during mechanical stick and fouling cavity.
