Micro Screen

A Hubert micro screen is widely applicable for fine-filtration of large water flows

A Hubert horizontal rotary micro screen or micro strainer can be used  for pre-treatment of influent & effluent in a waste water treatment plant.

More efficient reuse of wastewater from municipal wastewater treatment plants or industrial production processes, make use of these filters increasingly interesting. Think of the recovery of useful raw materials from waste water or process water,  such as cellulose fibers, but also stricter discharge requirements.

These micro filters are custom engineered in which the customer plays a major role in achieving the correct efficiency, as he usually has the most experience with his process.

Other applications can be found in (fresh) water intakes, acting as (fine) pre-filtration system being part of potable water production plants or production plants that consume a lot of process water. See also Water Intake Systems / Drum screen

Micro screen or Micro Strainer

A Hubert micro screen or micro strainer is used for filtration of large water flows

Flow rates can be up to 5000 m3/h per screen, depending on customer requirements and application. Woven fabric or mesh with a diameter of about 11 up to 500 micron is used as filter medium. This type of filter is usually used under free fall conditions. The efficiency and capacity of a micro strainer depends on several factors including the characteristics of the fine filtration mesh (fabric), rotation speed of the micro screen, the quality of the water to be purified and the amount of backwashing water.

Design, Construction & Operation

The Hubert micro screen system consist of a drum fitted along its outer circumference with screen panels. The drum is placed in a concrete pit or tanks and rotates on a stationary hollow shaft fitted with one or more funnel-shaped debris collectors. The feedstock of water enters the drum axially and flows radially through the mesh panels. The dirt particles remain trapped in the mesh.

As the drum rotates the row of sceen panels pass under a set of high pressure water jets at the top of the drum. The dirt particles are washed from the screen and discharged through the funnel-shaped debris collectors and the hollow shaft.

The “clean” side of the screen compartiment is fitted with an overflow weir which enables the water inside the screening chamber to be kept at a constant level. This ensures that the largest possible screening area is constantly submerged resulting in a high yield of solids.
