  • Publication number: 20240092054
    Abstract: A thermoplastic film which exhibits elastic-like behavior along at least one axis when stretched or elongated and then released. The thermoplastic film comprises a plurality of raised rib-like elements extending in a direction perpendicular to a main surface of the thermoplastic film. The thermoplastic film further includes a plurality of web areas positioned about the plurality of raised rib-like elements. The plurality of raised rib-like elements and plurality of web areas are arranged in a complex pattern. The complex pattern provides visual and tactile cues as the films are stretched or elongated. The complex pattern can cause the thermoplastic film to have a complex stretch profile.

  • Patent number: 10752533
    Abstract: A method for treating waste water containing ammonia comprising the steps of: i) passing the waste water as a feed solution through a first RO membrane (24) to produce a first permeate stream (30) and a first reject stream (32), ii) adjusting the pH of the first reject stream (32) to >9, iii) passing the first reject stream (32) through a second RO membrane (26) to produce a second permeate stream (36) containing ammonia and a second reject stream (38), and iv) passing at least a portion of the second permeate stream (36) to a cooling tower (12) to evaporate at least a portion of the ammonia.
