Article 2 
1. For the purposes of this Directive, 'liquid 
wastes' means: 
— in the case of the sulphate process: 
— strong acid arising from the separation phase 
which follows on from the hydrolysis of the 
titanium oxide solutions and containing 
between 20 % and 23 % free sulphuric acid 
and various metallic salts 
and 
— weak acid at a concentration of between 5 and 
7 %, arising from the washing phase which 
follows on from the separation stage and also 
the other wash waters, and in particular those 
associated with the gaseous discharges from 
the manufacturing processes, including both 
the sulphate and chloride processes; 
— in the case of the chloride process: 
— free hydrochloric acid. Article 2 
For the purposes of this Directive, the following 
definitions shall apply: 
Liquid wastes 
— in the case of the sulphate process: 
— strong acid arising from the filtration phase 
following hydrolysis of the titanyl sulphate 
solution or from association of such acid with 
weak acid and containing more than 0,5 % 
free sulphuric acid and various metallic salts 
and 
— weak acid containing 0,5 °/o or less free 
sulphuric acid, such as wash waters, cooling 
waters and condensates, but excluding diluted 
strong acid, 
— wastes arising from the treatment of the 
abovementioned wastes and containing various 
heavy metals, including the non-separated solid 
wastes; 
— in the case of the chloride process: 
— acid containing more than than 0,5 % free 
hydrochloric acid and various metallic salts, 
— weak acids containing 0,5 % or less free 
hydrochloric acid, such as wash waters, cooling 
waters and condensate, but excluding diluted 
strong acid, 
— wastes arising from the treatment of the 
abovementioned wastes and containing various 
heavy metals, including the non-separated solid 
wastes.

'Insoluble matter' means: 
products, which are not broken down by the 
sulphuric acid during the manufacturing process. 
'Copperas' means: 
crystallized ferrous sulphate (FeS04 - 7H20), 
separated out in solid form from the titanyl sulphate 
solution. 
'Refei ral rence value means: 
— for liquid wastes: 
— in the case of the sulphate process: 
the quantity of free acid, in the form of 
sulphuric acid, arising from the strong acids 
and/or weak acids containing, whether 
dissolved or in suspension, salts of metals such 
as Ti, Fe, Cr, Ni, Zn, Pb, Mn, V, arising from 
the manufacturing process, with the exception 
of copperas; 
— in the case of the chloride process: 
the quantity of free acid in the liquid wastes in the 
form of hydrochloric acid containing metal 
chlorides; Solid wastes 
— in the case of the sulphate process: 
— insoluble solid ore residues not broken down 
by the sulphuric acid during the manufacturing 
process, 
— copperas produced as crystalline ferrous 
sulphate (FeS04 - 7HzO) in solid form, 
— filtration salts and sludges broken down during 
treatment of the strong acid wastes; 
— in the case of the chloride process: 
— insoluble solid ore residues not broken down 
by the chlorine during the manufacturing 
process, 
— metal chlorides and metal hydroxides (filtration 
substances) produced in solid form during the 
manufacture of titanium tetrachloride, 
— coke residues arising from the manufacture of 
titanium tetrachloride, 
— filtration salts and sludges broken down during 
treatment of strong acid wastes. 
Reference value for liquid wastes 
in the case of the sulphate process: 
the quantity of all sulphates (expressed in kg of 
S04 per tonne of titanium dioxide produced) 
discharged by an undertaking into surface fresh 
waters, coastal waters, territorial sea waters and 
the open sea, i.e. the quantities of all sulphates 
corresponding to the S04 ions contained in the 
free sulphuric acid and in the metallic sulphates; 
in the case of the chloride process: 
the quantities of chlorides (expressed in kg of CI 
per tonne of titanium dioxide produced) 
discharged by an undertaking into surface fresh 
waters, coastal waters, territorial sea waters and 
the open sea, i.e. the quantities of chlorides 
corresponding to the CI ions contained in the free 
hydrochloric acid and in the metallic chlorides.
