But these water purification systems are some of the best on the market. The best way to assure you are removing harmful live pathogens is to boil vigorously when possible. When boiling is not possible, use chlorine tablets. However, the Travel Berkey is one of the best available and is us...
Therefore, we installed a water purification system by treating the water in a large tank with chlorine and aluminum sulfate, with subsequent filtering of solids via a sand filter and excess chlorine with carbon filter. This was probably the first bulk water purification system on Molokai. The pr...
One of the purposes of a supramolecular chemist is to mimic biological systems, where complex reactions with high noncatalyzed energy barriers proceed effectively with excellent selectivity. Effective control of enzymes on substrates is achieved by isolating substrates in the active sites. Therefore, it...
