The leather fmishing industries consume great amounts of water and

insufficient to comply with the existing legislation.
Colour is one of the pollutants common to all these industries. This is a
parameter normally difficult to eliminate and furthermore, greater restrictions
in the legislation relating to the discharge of industrial residual effluents are
being contemplated more and more.
In this present work, ozone and ozone with hydrogen peroxide have been
studied in order to determine which of them are more effective in the
reduction of the colour present in the w
