In aluminum heat exchanger production, a non-corrosive flux is applied to individual parts or to assembled units most commonly as an aqueous flux suspension by flooding, spraying or dipping. Wastewater from cleaning the fluxing apparatus and waste flux slurries are often simply diluted and discharged to the environment or treated for fluorides. This paper presents a method for eliminating wastewater from such operations by recycling and reusing the wastewater to make up new flux slurries or to top up existing slurries. Results of flux slurry filtration tests will also be presented. Other alternatives such as a master/process slurry tank configuration are discussed for minimizing the quantity of wastewater.
