摘要： A method for recycling contaminated flush water from a wet electrostatic precipitator emission control system in a wood panel fabrication process. The recycled flush water containing solid byproducts from the emission control system is combined with wood products in a wood panel fabrication mix in a predetermined ratio of flush water to wood products, resulting in a finished wood panel having improved internal bond strengths and formaldehyde scavenging capacity without the need for excess binding resins and formaldehyde scavengers.

摘要： A thin film membrane filtration system recovers particulate from the waste water stream of a wood panel fabrication process to a desired concentration of approximately 30-50% solid by weight. The high concentration level enables improved transport or disposal. Rather than discard the concentrate, however, the concentrate is added into subsequent wood panel "particle board" batches at a rate of approximately 0.5 to 0.65 gallons per 1000 pounds of wood product. The concentrate reduces press time, serves as a scavenger for tying up formaldehyde and serves as a resin extender for strengthening internal bonds of fabricated panels. The membranes capture the particulate into an accumulated concentrate, while passing permeate output to a recycle water stream.
