Desalination of seawater with supported liquid membrane

Abstract

Abstract Seawater contains a lot of dissolved substances which are important chemicals. Broadly speaking the chemical composition of seawater is the main constituents of salinity, trace elements, gases, organic compounds, and suspended material. Desalination techniques have long been known and carried out, among others, by distillation, reverse osmosis, ion exchange (ion exchange) and electrodialysis. SLM is a separation technique consisting of two homogeneous phases, namely the feed phase and the receiving phase. Separation with SLM techniques is largely determined by the effectiveness and selectivity of the carrier compound. In this study using D2EHPA-TBP and HTTA-TBP as a carrier compound which was then applied in decreasing salinity levels of seawater. Seawater desalination with the SLM technique for carrier compounds was 81.690% and 84.504%, respectively.
