Effect of feed water composition and pretreatment on the irrigation water for boron-sensitive crops

The membrane filtration is an effective way to produce water for human consumption, industrial use, or irrigation purpose. In this study, the potential of a brackish reverse osmosis (BWRO) was practically investigated obtain with quality from geothermal water. produced analyzed understand applicability in agricultural use boron-sensitive crops. effects feed solution composition and pretreatment by microfiltration were studied. Results showed that ionic content reduction permeate flux. However, rejections salt silica did not change significantly they successfully removed more than 95% rejection. Pretreatment (MF) having pore-size 0.8 µm provided higher flux one pore size 5 µm. boron only achieved increased pH pretreatment. 9.5 rejection as 75% concentration 2.4 mg/L when 15 bar operating pressure employed. This level found be allowable some resistant semi-sensitive
