Bongo dual-aperture fine screens from Ovivo are suited for pre-membrane screening. The 3 mm ProPaPanel screening panels provide a first-stage screen for removal of influent debris without excessive blinding. Internal elevators transport captured debris to an internal trough where low-pressure wash water conveys screenings to a handling system. It can also be used for water intakes or for pre-screening of any equipment that needs protection in the 300- to 1,600-micron range, but contains source water with large or sharp debris that could overwhelm or destroy a mesh screen. 512/834-6000; www.ovivowater.com.
