Bar screens are a common type of fine screen. They have vertical or slanted bars spaced apart. These screens catch large trash like rags, sticks, and plastics. Removing these items early stops clogs and protects equipment.
Bar screens are placed where wastewater first enters the plant. They can work manually or automatically. Automatic bar screens use rakes to clean themselves. This makes them great for systems with lots of water flow.
Drum screens are round and spin to clean water. They trap small particles like fine solids and fibers. The drum has tiny holes or mesh that let water through but block debris.
Drum screens are very good at catching small waste. For example, a 3-mm drum screen can catch up to 95% of debris. A 1-mm mesh screen can catch up to 98%. Their spinning motion keeps them from clogging, so they need less cleaning.
| Screen Type | Max Speed (ft/s) | Capture Rate (%) |
|---|---|---|
| 6-mm round-hole | 2.5 | 81% - 75% |
| 3-mm round-hole | 1.5 | 95% - 90% |
| 2-mm round-hole | 1.3 | 97% - 92% |
| 1-mm mesh | 1.2 | 98% - 97% |
| 0.5-mm mesh | 1.0 | 99.7% |
Drum screens work well with different water flows. This makes them a top choice for modern plants.
Step screens use plates that look like steps. These plates trap solids as water flows through. The steps move, lifting debris upward while keeping water loss low.
Step screens handle large amounts of water with mixed debris sizes. They clean themselves, so they don’t need much maintenance. They also work with both big and small waste, making them flexible for many needs.
Knowing about bar, drum, and step screens helps you pick the right one. Each type keeps your system running smoothly and meets environmental rules.
Mesh screens are great for catching tiny particles in wastewater. They use tightly woven material to trap debris while letting water pass. The size of the mesh holes decides what particles it can catch. Smaller holes can trap finer particles, making them perfect for advanced cleaning.
These screens can be used in different treatment steps. They are especially helpful when very clean water is needed. Industries like food processing and medicine rely on them for precise filtering. By removing even tiny contaminants, mesh screens keep the system running smoothly.
