Studies on the purification of water by the ceramics materials

摘要

Effects of ceramics in water purification were evaluated. All ceramics materials tested suppressed the growth of algae. This effect was particularly strong with the magnesium oxide -added ceramics and with FIB-25. pH was higher in the fields treatedwith ceramics containing magnesium oxide. EC tended to be lower in the fields treated with ceramics containing magnesium oxide and in the FIB-25 treated fields. The addition of ceramics containing magnesium oxide to soil resulted in markedly improved water quality through suppression of algae growth and adsorption of phosphorus. This ceramics is promising as a means of improving water quality.
