Sewage treatment comprises of a number of thorough stages to get rid of trash, grit, grease, and other impurities, so that the clean water can be produced. Many screens, biological deterioration, chemical addition, disinfection, and other processes are all part of the sewage treatment process.
The removal of the larger substances from the sewage is the first stage, and bar screens is required for this.
What is bar screening in STP?
A bar screen is a filter that eliminates large solid particles from sewage. It is a kind of coarse screen that removes debris from any running water, including rags, plastic, papers, metals, etc. It typically comprises of vertical steel bars that are separated by 1 to 3 inches. Typically, it comes first in sewage treatment systems.
Why are bar screens required in sewage treatment plants?
We can avoid damage and needless wear and tear by eliminating the big solids. This lowers the system's overall maintenance requirements and risk of problems.
Large solids removal also reduces interferences during the entire treatment procedure. For example, it stops clogging and protects the waterways from contaminants.
How does bar screens work?
The most basic bar screens merely feature vertical bars that stop large items, while allowing water to pass through. The objects within the screen have a tendency to accumulate, which might obstruct water movement and raise backwater levels.
Nowadays, conveyor systems are commonly used in industries and other facilities. In this kind, bars or wires pick up the solids that are trapped in the screen, and move them to a different location.
This approach prevents clogging and maintains a continuous flow of water. Without this technique, the bar screens might quickly become blocked. This can occur frequently when there are large amounts of coarse particles present, or if there is a rapid water flow. Also, the gathered items are placed in another container with a specific capacity.
Application of bar screens
These screens can be employed in a wide range of industrial settings, including paper mills, food and beverage companies, slaughterhouses, etc. Since, these devices are frequently customised, your bar screen will typically be unique to your system.
· Designed to fit into wastewater conduits and fixed in place,
· Designed to remove waste's medium to fine particles,
· Cost savings as a result of fewer obstructions,
· Created with self-cleaning elements like washing nozzles, and
· Brushes to extend its useful life.
Conclusion
A manually cleaned bar screen (big in size to reduce the frequency of screenings collection procedures) or, ideally, an automatically cleaned bar screen is used for screening, essential in cases of high flow rates of for water with a high solids content.
In larger facilities and when raw water contains a lot of coarse matter, a durable preliminary bar screen that protects the automatic bar screen, should also have an automatic cleaning system.
Even in small establishments, screening methods are becoming automated to minimize manual tasks. Automation is necessary when significant amounts of plant debris are transported by the water, and come at the bar screen all at once, tending to mat the bars and clogging the screen completely in a short amount of time. Therefore, automated fine screens are required.
