The stationary hydrosieve , also widely known as a static wastewater screen or a sieve bend screen , is the most trusted and simple solution for liquid-solid separation in wastewater treatment fields. This non-powered equipment plays a critical role in pre-treatment, effectively removing solids to protect downstream systems and improve overall process performance. T he Science Behind the Static Screen A stationary hydrosieve operates on a simple, yet highly effective principle based on the Coandă effect. The unit consists of a curved, parabolic screen, typically constructed from durable stainless steel. This curved screen features a series of triangular or V-shaped wedge wires. As wastewater or process fluid flows over the inclined surface, the liquid adheres to the curved screen bars due to surface tension and the velocity of the flow. The design creates a controlled hydraulic action: • Deceleration of Screenings: The curve of the screen slows the solids, allowing them to tumble and ...
