Abstract:
In this paper we study a natural absorbent and biodegradable material, which could be deployed in the event of an accidental pollution of lakes, rivers, seas and oceans by spills of oils and hydrocarbons and also can be used to clean soil affected by leaks of oils. This type of water cleaning is used by companies from different regions across the globe and is a method that nature kindly provides to us. As a case study we present the measurements and the analysis of an intervention with biologically absorbent material on three types of oil (household oil, unused motor oil, used oil. The samples show both the rapid absorption of the oil from the water and the physical-chemical properties improvement of water treated with biodegradable material based on sphagnum moss. The main conclusions of the paper are based on the absorption capacity of the proposed material and the absorption kinematics for each sample. Thus, we found evidence proving that this material can be used with a very good yield under conditions in which the costs are minimal and it is easy to use. In the case of accidents that adversely affect water quality and lead to the destruction of ecosystems, the population should use ecologically alternatives for cleaning which lead to energy saving and which does not involve the consumption of other resources. The quality of the water after the sphagnum intervention has been recognized as being substantially improved. A noticeable decrease in the nitrate value in the resulting water samples demonstrated that the natural biodegradable materials that nature offers us can be a valuable part of a better solution to current methods widely used. These natural materials would maintain clean water which is increasingly becoming a rare commodity
