At present, protection of the environment from waters contaminated by oil and oil-processing numerous products is one of the main tasks. To purify these waters, different methods have been used – from mechanical to biological. The easiest and most effective is leaking filtration in adsorbent layer. Any porous material can be used as adsorbent, among them are coals. The percolating filtration in the adsorbent layer is the most common and efficient method for purification of the sewage, contaminated by the oil products. Any porous material, including coals, may be used as an adsorbent. In the course of the study of Tkibuli- Shaori deposit coal (Georgia), as a gas collector, it has been established that it is characterized by a developed system of mesopores and by a high adsorptivity with regards to the gases. To select the optimal conditions for waste waters’ purification, different factors of influence on waters’ purification quality have been studied, namely grain sizes of loading filter, thickness of the coal layer and filtration velocity, variability of oil product’s initial concentration, medium pH and temperature.
