Claim:
A washwater recovery system for a fiberglass product forming line including a first product forming component in which is utilized a low pH binder to produce said fiberglass product, a second production component, and low pH washwater cleaning system operable to remove binder and debris from said first product forming component and a bulk washwater cleaning system operable to clean said second production component, comprising: a bulk washwater recovery loop operable to collect bulk washwater from said second production component for recycling and return to said second washwater cleaning system for cleaning said second production component, said bulk washwater recovery loop including: a first screening apparatus to remove large particles of debris from said bulk washwater and create screened bulk washwater; a bulk washwater supply tank to receive said screened bulk washwater from said first screening apparatus; a first pH probe operable to sense the pH level of said screened bulk washwater; and a neutralization system operably coupled to said first pH probe and being in flow communication with said bulk washwater supply tank to deliver a base solution thereto until said pH level of said cleaned bulk washwater is approximately 8 or above before being returned to said second washwater cleaning system; and a low pH washwater recovery loop operable to collect low pH washwater from said first product forming component for recycling and return to said first washwater cleaning system for cleaning said first product forming component without treating said low pH washwater to change the pH level thereof.
