Bar Screen

The advantages of the Bar Screen are embedded in the technical solutions

• Grids are one of the best solutions in the market of equipment for mechanical treatment in terms of reliability and efficiency.
• The design of the grids has been developed taking into account many years of practical experience in the operation of the equipment at municipal and industrial treatment plants. The engineering solutions realized in the grids are characterized by high reliability and efficiency.
• Modeling of the grate operation and its performance in each specific case.
• Adaptation to any task.

This results in high longevity of the Bar Screen:

• perfect mating of housing parts and grating mechanisms due to the application of high-precision manufacturing technologies;
• high corrosion resistance achieved by using stainless steel (AISI 304, AISI 316), which is extremely important for its use in aggressive wastewater environment;
• the grating production process includes anti-corrosion treatment: volumetric etching and passivation with special agents;
• mechanical protection: safety clutch of the drive mechanism with spring force adjustment;
• electrical protection against overload and power surges;
• sprockets of the drive mechanism of the grating have an increased number of teeth, are made of wear-resistant polyamide, are not subject to corrosion and are durable in operation;
• use of powerful drive chains with plastic rollers. Their main characteristic is durability and wear resistance. Due to the use of rollers
• friction during rolling is minimized and maximum efficiency is ensured;
• there is no need to worry about the condition of the permanently submerged parts of the grid - there are no rotating elements in the submerged zone, and the tine drive chains move on polymer sliders;
• reinforced rake design is used;
• the scum ejector is made with polyamide lining, which allows to reduce the wear of the grid.

Why are the Bar Screen convenient in operation?

• maximum maintainability: the grids are easy to maintain due to the availability of the main components in working condition. The grating can be lifted out of the channel without dismantling it thanks to the original swivel mechanism. There is no need to empty the channel or dismantle the entire structure;
• the filter cloth can be easily replaced in case of damage;
• closed, hermetically sealed construction, ergonomic quick-release covers for grate inspection and routine maintenance;
• easy maintenance of the grate chain - easy access to the chain tensioning mechanism. Easy adjustment of the grate chain mechanism;
• special design of the ejector, which ensures optimal removal of the waste and its non-return into the channel.
