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...

Industrial filtration systems are essential for removing suspended solids and protecting equipment in many applications. However, conventional filtration methods often require manual cleaning or frequent replacement of filter elements. Automatic self-cleaning filters provide an alternative solution by allowing continuous filtration with reduced maintenance requirements. What Is a Self-Cleaning Filter? A self-cleaning filter is an automatic filtration system that removes accumulated contaminants from the filter screen without requiring frequent manual cleaning. Unlike traditional filters, the cleaning process is controlled automatically through differential pressure monitoring or preset operating conditions. How Does It Work? The working process is simple: Contaminated liquid enters the filter housing. Particles are captured by the filter screen. Contaminants accumulate and increase pressure difference. The automatic cleaning system removes trapped particles. The filter returns to norm...
