    摘要： Strip diffusers are disclosed for use in wastewater treatment plants. Such a diffuser has an elongate diffuser body (280) with a gas supply channel and a support member (285) on which a flexible membrane (298) is mounted. Each longitudinal edge of the membrane is held in a groove (295) in the diffuser body by means of one or more locking or jamming members (300). This holds the membrane in place, and with the support member, at least when the diffuser is operating, defines a gas chamber from which gas passes through the membrane. The locking or jamming members may be held in place by a flange extending over the groove, or by engagement of the locking or jamming member with the membrane and compressing the membrane against the groove sidewalls (297).

    摘要： A strip diffuser has an elongate diffuser membrane support defining an upper surface for location of the membrane. An elongate groove is formed in a lateral portion on either side of the support for receiving a marginal edge portion of the membrane. The marginal edge is secured in the groove by means of an elongate securing member. The sidewalls of the groove are formed with at least one elongate projection, and the securing member has a cross-section large enough to clamp the marginal portion of the membrane against that projection upon insertion of the securing member into the groove over the membrane. Normally, the sidewalls of the groove are formed with at least one opposed pair of elongate projections.
    In an assembly of the invention the height of the projection or projections is normally a substantial portion of the thickness of the membrane. A typical height is in the range 0.2 to 0.4 mm, and based on measurements from the groove sidewalls, inclined at an angle of about 45 degrees.
