Brackish water treatment with local filter media and reverse osmosis using application of internet of things technology / Surya Hermawan ... [et al.]

Global clean water crisis is affecting more than 40% population and still increasing. As an archipelago state with large coastal area, Indonesia is however facing the common issue with the clean water shortage. There are still lack of access to clean water and water treatment plant for the community in the coastal area to fulfill their daily needs and drinking water as most water source is brackish water with higher salinity than fresh water. Hence further treatment is required to obtain the clean water and safe for daily consumption. The objectives of this research work are to determine suitable local material for water treatment and alternatively by using reverse osmosis equipment which is expected to reduce salinity of treated water. As methodology used in this research, a physical treatment experiment on the brackish water is conducted through a selected local filter media and by using reverse osmosis equipment with the assistance of internet of thing technology. The research work outcomes demonstrate that treated water by filtering has indicated a clear physical appearance and odorless but no significant improvement on pH and about 3,67% reduction on TDS value and 7.0% on EC value. On the other side, the treatment through reverse osmosis method is showing better result with significant improvement with 99.5% TDS and EC value which can’t be achieved by filtering treatment.
