The Great White center/dual flow screen from Hydro-Dyne Engineering has been independently certified to have a high screening capture ratio. It easily collects and off-loads screenings, including rags and stringy material. Its dual spray wash grid design, sealing system and UHMWPE guide links make it ideal for the filtering and off-loading of water and wastewater screenings. The sealing system ensures all tolerances are held to 1/2 mm. It is designed to handle low to high flows with 1/2 to 25 mm openings, and can be incorporated into a septage receiving station. 813/818-0777; www.hydro-dyne.com.
