This method keeps the flow of water steady as there’s a lower risk of clogging. Without this mechanism, the bar screens can get clogged within minutes. In cases of high volumes of coarse matter or high-speed water flow, this can happen a lot.

Before you start, be aware of outside lighting – in many cases, the wiring from fixtures is hidden within the joints of your wall, so make sure you isolate the circuit before chipping away. A small advantage is that the equipment requires little maintenance at all. Small plants with only a few screenings can also make manual bar screens work for them. Mechanical Bar Screen For a smooth and continuous operation, it’s important to prevent clogging. The flow of water must remain steady at all times, which is why we have different types of bar screens today. They differ on the cleaning system.

The steel is coated with a protective layer of zinc which helps to prevent the railings from rusting. The size of the openings range from 1 inch to 2 inches (30 mm to 50 mm). The bars incline at 30 to 45 degrees, which facilitates better cleaning.

A bar screen is a filter that removes big solid objects from the wastewater. It’s a type of coarse screen that takes out rags, plastics, papers, metals, etc. from any flowing water. As the name implies, it usually consists of vertical steel bars spaced 1 to 3 inches apart. By removing the large solids, we can prevent damage and unnecessary wear and tear. This reduces maintenance needs and potential issues for the whole system. Aside from the ease of cleaning, mechanical screens also improve the flow conditions. This system is not as labor-extensive, so it reduces labor costs. However, it has higher initial costs and it’s much more expensive to maintain.We have offices across the UK and can provide our services nationwide.

Go further with metal railings Mechanically-cleaned bar screens have smaller opening sizes of 0.25 to 1.5 inches (6 mm to 36 mm). The bars can be steeper at 0 to 30 degrees as employees don’t have to rake the debris. A catenary screen has a rake that’s positioned against the bars. The rakes travel upwards to deposit the waste in a chamber. These railings are hard to climb over and effectively restrict people from climbing through the railing gaps. The railing bars are also positioned so that you can still have a clear view through the system without obstruction.
