Title: Alfred Henz and a Process for Purifying Dyeing Wastewaters.
Introduction
Alfred Henz is an inventor associated with Reinach, Switzerland. His patent work includes a membrane-separation process designed to purify and decolorize dyeing wastewater.
Latest Patents
Henz is credited with 1 patent, titled “Process for Purifying Dyeing Wastewaters.” The process begins by adjusting the wastewater to a pH between 4 and 9 through the addition of acid or alkali. A first membrane-separation step produces permeate and concentrate; the concentrate is then further decolorized and deionized in a second step. Permeate from the second step is recycled to pretreatment, while the first-step permeate and the concentrated wastewater from the second step are disposed of conventionally.
Career Highlights
Henz is associated with Ciba-Geigy Corporation. His patent describes a staged treatment approach that combines membrane separation, wastewater recycling, and conventional disposal of residual streams.
Collaborations
He is identified as a coworker of Heinz Pfenninger. The available information does not specify their particular projects or working relationship.
Conclusion
Alfred Henz’s recorded patent presents a two-stage membrane process for treating dyeing wastewater, with recycling of one permeate stream and conventional disposal of the remaining outputs.
