Microscreens

Fine Filtration for Large Water Flows

Hubert micro screens, also known as horizontal rotary micro strainers, are widely used for pre-treatment of influent and effluent in wastewater treatment plants. These filters are increasingly important for efficient reuse of wastewater from municipal plants or industrial processes, enabling recovery of valuable raw materials like cellulose fibers and meeting stricter discharge requirements.

Custom-engineered for optimal efficiency, Hubert micro screens are tailored to meet customer-specific needs, leveraging the client’s expertise in their processes.

Additional applications include (fresh) water intakes, where they serve as fine pre-filtration systems in potable water production plants or industrial facilities consuming significant amounts of process water.

Hubert’s horizontal drum screens are designed to discharge debris through the main shaft, with the filter positioned in an enclosed pit or tank.

Our definition of horizontal drum screen implies that debris is discharged through the main shaft and the filter lies in an enclosed pit or tank.

High quality

We provide premium installations and sub-installations for use in municipal and industrial wastewater treatment plants. Known for their exceptional quality, our systems offer a long service life and reliable performance.

In addition to the micro screens highlighted here, we also supply a range of coarse screens designed to meet the needs of the wastewater treatment market.

Micro Screen or Micro Strainer

Filtration of Large Water Flows

Hubert micro screens can handle flow rates of up to 5000 m³/h per screen, depending on customer requirements and specific applications. These filters use woven fabric or mesh with diameters ranging from 11 to 500 microns as the filter medium. Operating under free fall conditions, micro screens achieve a filtration degree of less than 1 mm. Their efficiency and capacity depend on factors such as the mesh characteristics, rotation speed, water quality, and the amount of backwashing water required.

For filtration needs with a hole diameter starting from 0.5–1 mm, Hubert provides perforated (rotating) drum screens that use perforated plates as the filter medium. For larger filtration requirements (>1–2 mm), travelling band screens or larger vertical drum screens are commonly used in open-channel water intake systems.
