Re-use of pure cooling water<br />
and condensate<br />
Case illustration:<br />
Re-use of warm cooling<br />
water in high temperature<br />
processes in jets<br />
Concept Great amounts of heated up cooling water and condensed steam are produced<br />
within <strong>the</strong> textile dyeing industry, e.g. from vacuum pumps, compressors,<br />
bearings, indirect cooling and heating of dyeing machines etc. The only<br />
parameter that differentiates this water from normal process water is <strong>the</strong> temperature.<br />
In some cases <strong>the</strong> pure, warm and often softened cooling water and<br />
condensate is re-used with its calorific content, but in many cases this is not<br />
<strong>the</strong> case, and <strong>the</strong>n re-use should be considered.<br />
Improvement potentials Savings in water and effluent by water re-use and energy savings by using <strong>the</strong><br />
hot water in high temperature processes in <strong>the</strong> production.<br />
