An experimental investigation on the removal of heavy metals (HM) and petroleum products (PP) from a solution by natural sorbents zeolite and vermiculite was carried out in a laboratory pilot‐scaled test bench. For this purpose a model of a runoff filter which was invented by the authors was used. 25 kg of natural zeolite and 2 kg of vermiculite were used for the filter charge. An experimental solution of 20 l contained 1 g/l of HM Cu, Pb, Zn, Ni and Mn nitrates and 200 ml of PP gasoline and diesel. The solution was poured into the filter through a funnel and passed over natural zeolite and vermiculite media. The first sample was taken through a sample mixer tap immediately after the contact of the experimental solution with the charge media, the second sample was taken after 5 min, then after 10, 20, 30, 60, 120, 240, 360 and 720 min. TOG/TPH analyser was used for measuring concentration of filtrate samples. The highest efficiency of 99,7 % was reached for PP removal from water.
