Mechanical coarse grill are used at the inlets of wastewater treatment plants and pumping stations. They can automatically retain waste carried by water. These screens are typically used as coarse screens in treatment facilities. They feature high flow capacity and permeability rates and can be produced in different widths and channel depths.
The equipment functions through multiple rakes attached to chains rotating on gears, which regularly scrape the screens.
To ensure a long service life, materials such as AISI 304 and AISI 316 stainless steel derivatives are commonly used in manufacturing.
Primarily used in preliminary treatment, these screens are effective solutions for handling solid materials and debris entering with water at the initial inlet of the treatment plant. These materials, which do not decompose in water, can increase the organic load within the facility and pose risks of malfunctioning mechanical equipment like pumps during operation. The equipment can be customized according to the specific characteristics of the facility. Key factors influencing equipment selection include process requirements and flow rate.
The main components of the screens typically include screen bars, screen frames, a drive mechanism, a rake system, and a discharge trough. The drive mechanism can be of single-rake or multi-rake type.
Bar spacings can vary between 10 mm and 90 mm. Material options for the screens include hot-dip galvanized carbon steel or AISI 304-316 stainless steel. The materials removed from the screens can be compressed to further reduce their volume.
Work comes first at SETA, which has an awareness of its team, from business partners.
