Foam forming method and apparatus

Apparatus and process for producing foam formed fibrous web in which the furnish is made up by mixing a thin water slurry of fibers at a consistency in the range of from about 0.5 to about 7 weight percent fibers with sufficient aqueous foam containing a surfactant and having an air content in the range of from about 55 to about 80 percent by volume to form a foamed fiber furnish containing from about 0.1 to about 3 weight percent fibers which is supplied directly to the forming felt or wire of a twin wire papermaking machine, adding makeup surfactant and discarding excess agueous foam from the process as required to maintain the desired volume of foamed liquid therein.

Recovery of surfactant from papermaking process

Surfactant is recovered from the foamed aqueous admixture recovered from a fibrous web forming process by draining surfactant-depleted liquid from the foamed aqueous admixture thereby forming a surfactant-enriched foam, separating the surfactant-depleted liquid from the surfactant-enriched foam and recycling surfactant from the surfactant-enriched foam to the fibrous web forming process in the form of a stream having a surfactant concentration exceeding that of the foamed aqueous admixture. The recycle stream may be obtained by removing air from the surfactant-enriched foam. Surfactant may also be recovered from the surfactant-depleted stream by aerating it to form a foam from which surfactant-lean liquid is drained. The process may be repeated on the surfactant-lean liquid until the surfactant content of the finally obtained lean liquid is sufficiently low to permit discharge to the environment.
