Guide to Screening in Wastewater Treatment

In the complex world of wastewater treatment within a wastewater treatment plant, screening stands as a pivotal process. It plays an indispensable role in ensuring the smooth operation and effectiveness of the entire system.

The primary mission of our wastewater screening equipment is to eliminate solid materials from the wastewater stream. These solid substances can be a real menace as they have the potential to pollute waterways, wreak havoc on our valuable equipment, and significantly undermine the overall efficiency of the treatment process. Hence, their removal is of utmost importance and cannot be overlooked.

Wastewater screens can generally be categorized into two main types: fine screen and coarse screen. 

And, these broad categories can be further refined into more specific types such as rotary drum screens, static screens, bar screens, and nozzle screens.

Let's first clarify the distinction between fine and coarse screens.

Fine Screens:

Our fine screens are designed with precision to capture tiny amounts of plastic, hair, and paper. Equipped with self-cleaning mechanisms, they effectively prevent clogging issues. Fine screens are predominantly used as a secondary treatment approach in the wastewater treatment hierarchy.

Coarse Screens:

On the other hand, coarse screens are engineered to handle larger non - non-biodegradable solids. This includes items like rags, wood, paper, and sanitary products. They are commonly deployed in the initial stages of wastewater treatment, especially in scenarios where large debris is frequently encountered.

Rotary Drum Screens:

In the wastewater treatment journey, rotary drum screens serve as a crucial pre-treatment solution. They are highly effective in separating solids such as debris, grit, algae, and sludge from the liquid portion. When wastewater enters the drum, it passes through a screen mesh. This Rotary Drum screen acts as a filter, capturing and retaining the solids while allowing the water to flow freely through the screen.

Static Screens:

Static screens are usually positioned in channels and tanks. They consist of either a flat or curved panel with closely spaced openings. As the wastewater flows through these screens, solid materials like sticks and leaves are trapped. Over time, these solid materials accumulate on the screen's surface, creating a filtering layer that can even capture finer particles. When this layer reaches a sufficient thickness, it can be removed either manually or automatically using methods like a spray bar, scraper, or conveyor. Our cost-effective wedge wire sidehill static screens are especially suitable for static dewatering applications or any wastewater treatment process where the separation of solids from liquids is relatively straightforward.

Bar Screens:

Bar screens are excellent at removing large particles from wastewater, including rags and plastic. They are often utilized as a primary pre-treatment method. Most of our mechanical bar screens feature vertically mounted bars that are highly efficient in capturing large solids. Moreover, these mechanical bar screens come with self-cleaning features for added convenience.

Customization Service:

We understand that every wastewater treatment system has its unique requirements. That's why we offer extensive customization options for our wastewater treatment screens:

Screen Size: We can tailor the screen size to precisely match the specific requirements of your wastewater treatment system.

Screen Mesh: Our screen mesh types can be customized to handle particular types of debris that your system may encounter.

Material: We can select materials based on your specific needs for corrosion resistance and durability.
