Optimization of counter<br />
current operations in<br />
continuous machinery<br />
Concept Continuous machinery is often operated in such a way that fabric is moved in<br />
<strong>the</strong> opposite direction of <strong>the</strong> water flow. Depending on <strong>the</strong> specific process,<br />
fabric can be treated by a number of processes taking place in separate sections,<br />
each section consisting of a number of baths. Numerous continuous<br />
machines are operated with inlet <strong>to</strong> and outlet from <strong>the</strong> individual bath, thus<br />
implying poor utilization of water and chemicals. Observations have indicated<br />
that application and optimization of principles of counter current operation<br />
could take place in several continuous processes, e.g. dyeing, washing and<br />
desizing.<br />
Improvement potentials Savings of water, energy and chemicals. Up <strong>to</strong> 75% saving when going from<br />
no counter current operation <strong>to</strong> full counter current operation. Experience with<br />
this option is described in more detail in Part 4.<br />
Relevance All companies with continuous machines.<br />
