- the water purification tablet of the present invention comprises
- halogens can be used as disinfectants, i.e., chlorine,
- Water purification coagulants include several inorganic metal salts
- sulfate also has the advantage of providing acidic, which aids in tablet
- the prior art composition CF has
- CF-processed water has an acidic pH of about 4.4.
- Drinking water pH is most palatable at pH range 6-8, and maximum
- the amount of aluminum sulfate added as coagulant is critical in
- Typical grades of aluminum sulfate are about 42% water, and this will shorten the stability of the composition. A lower water
