Bone char has limitations due to hygienic conditions on its production and irregular efficiency adsorbing fluorine.  It has been an useful solution for undevelopped countries.  We have developped a new technology, HINDROP, that doesn't require the treatment controls, energy, chemicals or specialized workers to manage it.  It works at any water conditions (pH, temperature or presence of any other elements) obtaining an adsortion capacity over 0,9 mg F/g  There are no wastes and it may be implemented at domestic or communal solutions
