Manual Bar Screen
Simple, rugged stainless steel coarse bar screen for STPs, ETPs and drains, with bar spacing from 6 mm upwards.
Low-cost screening for smaller plants and standby channels
Adroit’s Manual Bar Screen is a simple and reliable way to remove floating and solid waste from sewage, industrial effluent and storm water. There are no motors or moving parts. The screen is made to fit your channel, installed at an incline and cleaned with a rake.
We make manual bar screens in SS 304 or SS 316 with bar spacing from 6 mm upwards. They are commonly used as the main screen in smaller STPs and ETPs, and as the standby or bypass screen alongside a mechanical screen in larger plants.

Where a manual bar screen fits
Application
The first step in treating wastewater is to remove rags, plastics and floating debris that could damage pumps and obstruct downstream units. In plants where the flow and debris load are low to moderate, a manual bar screen provides a simple screening solution with lower initial investment than a mechanical screen.
In larger plants, a manual screen is usually installed in the bypass channel next to the mechanical screen, so the plant keeps running while the mechanical screen is being serviced.
How a manual bar screen works
Operation
The screen is a row of parallel bars fixed in a frame, installed across the channel at an inclined angle so the operator can rake it easily. Water passes between the bars and debris larger than the bar spacing is held on the screen.
An operator cleans the screen at regular intervals with a rake, pulling the debris up the bars on to a platform or tray at the top, from where it is removed for disposal. The bar spacing decides what size of debris is removed.
Where manual bar screens are used

Frequently asked questions
FAQ
What does a manual bar screen do?
It removes floating waste and solids from incoming wastewater to protect pumps and downstream equipment and keep the rest of the plant working efficiently.
How often should it be cleaned?
It depends on the flow and the debris load. The screen should be raked often enough that it does not block and cause water to back up in the channel. In many plants that means several times a day, and more during rain.
Can a manual bar screen handle high flows?
It is suited to low and moderate flows and debris loads. For large flows or heavy debris, a mechanical screen such as Rakeflow® saves labour and keeps the channel clear more reliably.
Why is the screen installed at an angle?
The incline makes raking easier and gives a larger screening area for the same channel depth.
What decides the design of a manual screen?
Bar spacing, bar size, angle of installation, material, flow and the channel dimensions. Every screen is made to the client’s requirement.
