Parabolic screens, also known as static or rundown screens, are a highly effective solution for various water treatment applications. Featuring a distinctive parabolic curve, these screens offer multiple advantages, including easy dirt removal and superior water filtration. Due to their innovative design, parabolic screens are increasingly being adopted across numerous industries.
The parabolic curve ensures that dirt and debris easily slide down the screen, facilitating effortless cleaning. This feature significantly reduces maintenance efforts and costs.
While the dirt is effectively removed, water seamlessly passes through the screen. This dual-functionality is particularly beneficial for wastewater treatment processes.
Parabolic screens can handle large volumes of water depending on the surface area. This makes them suitable for industrial applications where high water throughput is required.
Parabolic screens are virtually maintenance-free with no moving parts and a free-standing design. The reversible three-stage panels further extend the screen's lifespan, providing long-term efficiency.
Parabolic screens are versatile and find applications in various sectors, including:
Meat and Vegetable Processing Industry
Petrochemical Industry
Plastic Handling Industry
Sewage Treatment
Sugar Industry
These screens are particularly useful in static dewatering applications and are ideal for bypass or overflow channels where they are used occasionally.
Recommended values for some industries：
| Applications | Wedge wire screen slot sizes (mm) |
| Municipal – primary sewage | 1.5/2.5 |
| Poultry – feather | 1.5 |
| Meat – stock water/pen wash down | 0.5/1.0 |
| Fruit and vegetables | 0.25/0.50 |
| Brewery – spent grains/bottle wash | 0.75/1.0 |
| Mineral – coal wash/lime particulate | 0.5/0.75 |
| Forestry – white water/chip wash water/pulp thickening/rejects | 0.4/0.5/0.75/1.0 |
In addition to the basic design, vibrating parabolic screens are available for even better performance. The vibration helps in dislodging residues from the screen, preventing clogging and ensuring continuous operation.
Parabolic screens are constructed using wedge wire made from high-quality stainless steel (304, 316, 316L). The material ensures durability and resistance to corrosion, making them suitable for harsh industrial environments.
One of the standout features of the parabolic screen is its ability to utilize the Coanda effect. This physical phenomenon enhances the screen's efficiency by ensuring that water adheres to the curved surface, optimizing the separation process.
