Abstract
To remove suspended solids (SS)in lakes, ponds and estuaries, an automatic filtration system was developed. The system consists of a main body with a floater, three pumps, two float sensors, solar panels and batteries. The silica sand is used for the filter materials.The thickness of filter materials is 7cm,at this time,the sectional area is 0.13m2.Two solar panels were used for the power source.The clogging in this system can be prevented by a reverse water flow by an automatic control with the float sensors.The system was examined in Shimizu Utozaka pond.The results showed that the filtration removed about 30% of total SS.
