Question:
The water is made to pass through a 5 stage filtration process in which one of them is the RO membrane where water is being forced through it at high pressure. This is to filter off all the pollens, UVs and all the dissolved impurities, especially the heavier metals. I bought this just for health supplement for myself, my family and as an alternative to drinking water direct from the PUB tap. Any opinions?

Answer: I had gone from estate to estate, from Jurong to Pasir Ris and taking samples of water from Food Centres and Kopi Tiam. Our tap water has a pH values of between 8 to 8.5 (pure water is pH 7). This is because of the Chlorine and Fluorine added to it and therefore alkaline as a result. The TDS (Total Dissolved Solids) are in between 80 to 130 ppm (part per million). One way of bringing out the solid is to precipitate it with an electrolysis process. An anode and cathode metal is placed over a cup of water from the household tap and a current is passed through where the dissolved solids acts as a conductor. After a while, solid particles appears as precipitate and flocculates. The particle turns dark and black simply because of particle oxidation and not the water itself. Similarly, RO water remains crystal clear because all the dissolved solids had been filtered out and no impurities. The TDS of RO water is zero ppm and pH 7 exactly.
