Removal of Fe(II) from wastewater by using integrated complexation method: article

Wastewater produced from electroplating industry contain metals that can be harmful when released to environment. Thus, by treating the wastewater using a proper treatment can help the metals in wastewater to be removed before being disposed to environment. In order to treat the wastewater, characterization of wastewater must be done. This purpose will determine which metals or contaminants present in the wastewater and shows the condition of wastewater before being disposed into environment. By doing the wastewater characterization, it also can determine which method is suitable to remove the contaminants contain in the wastewater. In this study, the composite membrane with hybrid membrane was fabricated to remove Fe(II) from wastewater. The composite membrane with thin film composite made up from polysulfone membrane as the support membrane and hybrid membrane as the barrier layer. Sol gel method was used to formulate the hybrid membrane where the hybrid membrane was made up from polymer blended consists of poly(vinyl) alcohol PVA and chitosan. Then the hybrid membrane will be cross linked with tetraethyl orthosilicate (TEOS). The polysulfone membrane was made up by using phase inversion method. Next, the atomic absorption spectroscopy (AAS) was used to determine the percentage removal of Fe(II) from wastewater after undergoes membrane treatment by using thin film composite membrane. Wastewater of company A needed to be treated using membrane filtration due to its value after characterization tests as it violates standard effluent discharge to environment. Removal of Fe(II) from wastewater using hybrid membrane is 99.89% at pH 10 compared than using composite membrane with polymer blended.
