Description
A new silt fence with zeolite sheet was developed for the countermeasure against nutrient salts, radioactive cesium and heavy metal in the water. The fence has double layer of polyester sheet, which is generally used for the common silt fence, and zeolite sheet is enclosed with these layers. Its functions are filtration, separation and adsorption. A trial construction for countermeasure against eutrophication was carried out at a regulating reservoir in Shizuoka City. Field measurements and analyses of water quality and adsorption amount of nutrient salts for zeolite sheet were performed. The workability of the fence, adsorption of nitrogen for zeolite sheet, and filtration and separation of the fence were confirmed. In another trial, the durability for 12 months of the zeolite sheet in the fence was also verified.
