Abstract
A method of re-circulating washwater used to clean production components for the manufacture of fibrous insulation, e.g. fiberglass is disclosed. The method includes providing a bulk washwater recovery loop to re-circulate washwater used to clean the downstream air components, as well as a separate hoodwall washwater recovery loop to re-circulate hoodwall washwater. Re-circulated hoodwall washwater may be used to clean the forming hood components and for preparation of binder dispersions. In the latter case, the pH of the hoodwall washwater is measured and the binder dispersion may be prepared with 100% hoodwall washwater, 100% makeup water, or a blend of each depending on and in response to the pH measurement.
