BAT is to reduce water consumption by using one or a combination of the following techniques:

Technique	Applicability
(i) Minimisation of spillages and leaks	The technique is generally applicable
(ii) Reuse of cooling and cleaning waters after purging	The technique is generally applicable. Recirculation of scrubbing water is applicable to most scrubbing systems; however, periodic discharge and replacement of the scrubbing medium may be necessary
(iii) Operate a quasi-closed loop water system as far as technically and economically feasible	The applicability of this technique may be limited by the constraints associated with the safety management of the production process. In particular: open circuit cooling may be used when safety issues require for it (e.g. incidents when large quantities of glass need to be cooled) water used in some specific process (e.g. downstream activities in the continuous filament glass fibre sector, acid polishing in the domestic and special glass sectors, etc.) may have to be discharged in total or in part to the waste water treatment system
