The microorganisms pollution represent a dangerous condition of the water and the removing of these contaminants from it is very important to human and animal health. Adsorption is primarily used at the end of a treatment sequence for pollution control due to a high degree of purification that can be achieved. Activated carbon is considered the most popular adsorbent used for the application of the adsorption technique [1]. Granular carbon filters have been used for several hundred years and are considered one of the oldest means of water purification [2]. Our study presents the ability of activated carbons obtained from apricot husks to adsorb the bacteria from Gram-positive group: Bacillus subtilis and Bacillus cereus. These bacteria occur naturally in soils, at a concentration of up to one million per gram, and are therefore some of the most common microorganisms that can be grown in the soil. Also, because of the structure similarity with bacteria from other groups these specia can be used as test-models for the evaluation of the adsorptive properties of the activated carbon for bacteria from different specia. In the research as enterosorbent was used the activated carbon (AC-A) obtained from apricot kernels in a fluidized layer at a temperature of 1000oC by activation with steam for 30 min. It was determined the kinetics of the adsorption process of bacteria on the mentioned carbon enterosorbents and subsequently established the adsorption isotherms of bacteria at different temperatures. Results of the kinetics allows us to conclude that the equilibrium of the adsorption process of B. subtilis bacteria is established after 75 minutes of stirring, and in the case of B. cereus bacteria the equilibrium is established in 90 minutes. The adsorption isotherms of B. subtilis and B. cereus bacteria measured after 120 minutes of stirring at a frequency of 150 rpm at different pH values (1.97; 3.71; 4.05) and at different temperatures(26-36oC) showed that that the adsorption process of the bacteria is an exothermic one, i.e. with the increase of the temperature, the adsorption value decreases. The pH value of the solution has a different influence. In the case of B. subtilis, the decrease in pH leads to an increase in the amount of immobilized bacteria per unit area of carbon adsorbent, and in the case of B. cereus bacteria the effect is the opposite, a decrease in pH leads to a decrease in the number of immobilized bacteria on the carbon enterosorbent.
