Screening plays a vital role in the municipal and industrial wastewater treatment process. Proper screening protects wastewater treatment equipment and improves operations. Typically, the screen is the first device used at wastewater treatment plants and is designed to remove any large objects and prevent damage and clogging of downstream equipment, piping, and appurtenances.

Hydro-Dyne’s Great White Centre/Dual Flow Continuous Band Screen is designed to handle low-to-high flows and has been independently certified to have one of the highest screenings capture ratio of all band screens on the market.1 The dual spray wash, patented grid design, proprietary sealing system and UHMWPE guide links make this an exceptional product for the filtering and offloading of water and wastewater screenings.
Very low headlosses and extremely strong, well-reinforced grids make these centre flow (centre entrance, side exit) and dual flow (side entrance, rear exit) screens suitable for several applications in municipal and industrial water and wastewater solutions.
