Parabolic Screens--Efficient Water Treatment Solution

May. 27, 2024

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.

Parabolic Screens

Key Advantages of Parabolic Screens:

--Efficient Dirt Removal

The parabolic curve ensures that dirt and debris easily slide down the screen, facilitating effortless cleaning. This feature significantly reduces maintenance efforts and costs.

--Superior Water Filtration

While the dirt is effectively removed, water seamlessly passes through the screen. This dual-functionality is particularly beneficial for wastewater treatment processes.

--High Capacity

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.

--Low Maintenance

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.

--Applications Across Industries

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:

ApplicationsWedge wire screen slot sizes (mm)
Municipal – primary sewage1.5/2.5
Poultry – feather1.5
Meat – stock water/pen wash down0.5/1.0
Fruit and vegetables0.25/0.50
Brewery – spent grains/bottle wash0.75/1.0
Mineral – coal wash/lime particulate0.5/0.75
Forestry – white water/chip wash water/pulp thickening/rejects0.4/0.5/0.75/1.0

--Advanced Features for Enhanced Performance

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.

--Material and Construction

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.

--The Coanda Effect

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.
