Sidehill Screens in Wastewater Treatment

Wastewater treatment is a critical process that ensures the removal of impurities and contaminants from water before it is released back into the environment. One integral component of this process is the use of screens to separate and remove solid particles from the wastewater stream. Among the various types of screens, the sidehill screen stands out as a versatile and efficient solution for wastewater treatment facilities.

Understanding Sidehill Screens

Sidehill screens also known as parabolic screens or sieve bend screens are designed with a sloped, curved surface featuring a series of closely spaced parallel bars or wires. This unique design allows the screen to capture and separate solids from the liquid stream as it flows over the inclined surface.
Structure: Wedge Wire Screen/Johnson Screen
Material: Stainless Steel 304, 316, 316L, 312

Applications of Sidehill Screens in Wastewater Treatment

1. Municipal Wastewater Treatment Plants:
The wedge wire screen finds extensive use in municipal wastewater treatment plants for the removal of large solids, debris, and screenings before further treatment processes.
2. Industrial Wastewater Treatment:
Industries with diverse wastewater compositions benefit from the adaptability of sidehill screens, which can handle a variety of solid particles and contaminants.
3. Stormwater Management:
Sidehill screens are effective in stormwater treatment systems, preventing debris and pollutants from entering natural water bodies during heavy rainfall.

Features and Benefits of Sidehill Screens in Wastewater Treatment

1. Continuous Filtration:
The inclined surface of the sidehill screen facilitates continuous filtration as wastewater flows over it. This ensures a steady removal of solids from the liquid, preventing clogging and promoting efficient operation.
2. Adaptability to Varying Flow Rates:
Our parabolic screens are well-suited for applications with varying flow rates. The design allows for effective screening across a range of flow conditions, making them versatile for different wastewater treatment scenarios.
3. Self-Cleaning Mechanism:
One of the notable advantages of our sieve bend screens is their self-cleaning capability. As solids accumulate on the screen surface, gravity and the flow of wastewater help to transport them to the lower end of the screen, where they can be easily collected and removed.
4. Space-Efficient Design:
Compared to other screening technologies, sidehill screens are known for their compact and space-efficient design. This makes them ideal for installations where space is limited, allowing wastewater treatment plants to optimize their layout.

In the realm of wastewater treatment, sidehill screens stand as reliable workhorses, providing continuous and efficient solids separation. Their self-cleaning design, adaptability to varying flow rates, and space-efficient footprint make them a preferred choice for many treatment facilities.
