Material and energy consumption for production of 0.1 kg of adsorbents.

Process	Water consumption (m^3)	Electricity consumption (kWh)
Washing	0.002	—
Drying at 1050°C (24 h)	—	2
Crushing and sieving	—	0.5
Washing	0.0015	—
Total consumption	0.0035	2.5
Cost	0.035	3.5

In Egypt, the cost of 1 m³ of water for industrial use = 10.0 L.E. In Egypt, the cost of 1 kWh of electricity for industrial use = 1.45 L.E.
