Water Treatment Based on Ion Exchange Membrane Permeable Combined with The Field Electrodeionization (EDI)

Sugito ., Budi Prijo Sembodo


Water treatment can be done by ; removal of cations / anions contained in the water used: ion exchange resin (ion exchanger), deionization, distillation membrane transfer, flash evaporation, and reverse osmosis. But the way that can be done separately, each has drawbacks. If done multiple, can simultaneously support for removal of cations anions process contained therein. Water treatment processing procedures in this study are ; filtration using polipropylena, absorption by Manganese zeolite treatment, then ion exchange resins using anion and cation resin, continued with treatment electrodeionization (EDI) using membrane permeable cation and anion permeable membrane, which is arranged in cross, where the anode electrode attached adjacent by cation permeable membrane, and vice versa. Water treatment by technology based filtration, absorption, and ion exchanger with permeable membrane combined with electrodeionization (EDI) field concluded that; removal of some of parameters are: Total Disolved Solid (TDS) 752 ppm, Turbidity 4.94 NTU scale, color 40 units PtCo, Iron 0.55 mg/L Fe, Total hardness 457.24 mg/L CaCO3, Chloride 500 ppm, Nitrate 0.82 ppm, Nitrite 0.49 mg/L NO2-N, Zinc 0.07 ppm, Sulfate 9.14 ppm, Sodium 575.46 ppm, Organic Substances 17.74 mg/L KMnO4, and Detergent 0:06 mg/L LAS.

Keywords: ion exchange, filtration, absorption, membrane permeable, electrodeionization (EDI)
