2007 m. Nr. 3 Improvement of storm water runoff treatment system
with natural mineral sorbent
Rain and snowmelt water contaminated with petroleum products, heavy metals and other pollutants flows into roadside drainage ditches. The proposed system of runoff treatment contains a sorbtive of 0.2 m layer sand and 10% of natural zeolite. The soil surface of the runoff treatment system is overgrown with grass. The efficiency of the proposed infiltration-grassy-A-line type runoff treatment system with a natural zeolite layer is approximately 10% higher than of the ordinary runoff treatment system with a sand layer alone.
