In municipal wastewater treatment, pump blockages remain one of the most common causes of maintenance work and operational interruptions. Many facilities receive wastewater containing stones, branches, leaves, plastics, and other coarse solids. If these materials are not removed effectively during pretreatment, they can enter pumping stations and downstream treatment units, creating recurring maintenance problems. A recent municipal wastewater project in Japan provides a practical example of how improved screening can help address these issues. The treatment plant had been experiencing frequent pump clogging and increasing maintenance costs. To improve solids removal before wastewater reached the pumping station, the facility installed a wedge wire Hydrosieve Screen as part of its pretreatment process. Unlike powered screening equipment, the Hydrosieve operates using gravity flow and a static wedge wire screening surface. This design allows wastewater to pass through while retaining l...

Sieve bend screens are widely used in industrial filtration and wastewater treatment systems for efficient solid-liquid separation. Also known as DSM screens or curved static screens , these wedge wire screening devices are designed to handle high flow rates while reducing clogging and maintenance requirements. How Does a Sieve Bend Screen Work? A sieve bend screen operates using gravity filtration. Wastewater or slurry flows across a curved wedge wire screen surface. Liquid passes through the slot openings while solids continue sliding downward along the screen face. Because the screen is curved, the flow direction continuously changes during operation. This improves separation efficiency and helps create a self-cleaning effect. Unlike rotary screening equipment, sieve bend screens require no moving parts, which significantly reduces maintenance costs. Main Advantages of Wedge Wire Sieve Bend Screens 1. Anti-Clogging Structure The V-shaped wedge wire profile helps prevent particles...
