Current work focuses on investigating the rumours or myths saying that adding potatoes would be able to fix an oversalted dish, particularly soups. Based on our survey on the internet, there are various sources and blogs reporting yes and no. And the test they carried did not carry proper scientific and empirical methods. In this study, we carried out the experiment to test and find out if potatoes would be able to cause any effect on salinity through salt solution. With proper volume and mass measurement, salinity refractometer to record the salinity properly, and proper experimentation, we believe the rumours can be answered accordingly. The results showed that boiled potatoes immersed into salt solution (8%) indeed were able to reduce salinity up to 20 %. The potatoes did not act as an adsorbent, but functioned as water carriers allowing diffusion of salt ions from the concentrated solution into the less concentrated water region carried by the potatoes. In this abstract, we detailed out the methodology and further interpretation of the results.

Water treatment technology is one of the most important mechanism in our life. It turns unclean water into a clean and safely consumables by us. Over the years, research and invention over water treatment technology have progressed in terms of energy consumption, materials of interest, cost reduction, efficiency, land usage and mechanisms utilizing the concept of science around us. Conventional technology of water treatment can be categorized into physical, chemical, and biological treatments. Physical treatments include screening, filtration, sedimentation, flotation etc. Chemical treatment includes disinfection, precipitation, adsorption, ion-exchange, ozonation etc. Biological treatment involves aerobic and anaerobic biological treatments. However, there are new potential advanced technology being developed to clean our water in better way of many aspects. Among latest water filtration technology in water treatment interesting to discuss are nanotechnology, acoustic nanotube technology, photocatalytic water purification technology, aquaporin InsideTM technology and automatic variable filtration (AVF) technology. In this paper, the application of advanced technology in water treatment is discussed in a brief manner with latest development and challenge reported in the literature. With this review paper, hopefully, it will shed some lights for newcomers that want to learn or to get overview about current development of nanotechnology in water treatment system.
