Screens and screening solutions for water extraction

Products

Reliable water intake systems for open waters

HUBER offers its customers a comprehensive portfolio of innovative mechanical treatment systems for water intakes, for both new plants and the modernisation of existing plants. The systems are customised to the individual needs and the required water quality of each project.

Customers benefit from our decades of expertise for particularly stable and reliable fully automated machines with the best hydraulic properties for maximum separation rates. Depending on the application and installation situation, our solutions include multi-stage screens and screening systems that are optimally matched to each other.

Process Technology

HUBER solution for water intake

Preliminary screening

Preliminary screening is the first step in any water extraction process to remove large to medium-sized pollutants of more than 10 millimetres, such as leaves, tree trunks, plastic containers, plastic film, debris, seaweed and jellyfish. Mainly grab screens and multi-rake bar screens are used for this purpose.

Fine screening

For the removal of fine contaminants in the range of 1-10 millimetres, self-cleaning fully automatic belt filter screens are mainly used. They are suitable for filtering large flow rates in a water intake with a relatively fine degree of filtration. Depending on the required clean water quality of the downstream processes, the screen elements are equipped with filter mesh or with perforated plate. This ensures optimum reliability with maximum efficiency. HUBER belt filter screens are available in all sizes, layouts and for all flow rates. Depending on the flow direction, a distinction is made between

HUBER Band Screen CenterMax®: Screen of the "centre-flow" type. The filter elements are installed parallel to the flow direction of the water intake and move vertically. The water flows from the inside to the outside.
HUBER Band Screen DualMax®: Screen of the "dual flow" type. The filter elements are installed parallel to the flow direction of the water intake and move vertically. The water flows from the outside to the inside.
HUBER Band Screen DiscMax®:Screen of the "through-flow" type. The filter elements are installed in the direction of flow and move vertically. The water flows in a straight line through the filter belt screen.

Micro screening

For applications requiring high purity and removal of finest particles in the range of a few micromillimetres, such as mussel larvae, a micro screen is available as an option.

Shut-off devices

In addition to screen technology, HUBER also supplies shutoff devices as penstocks and stop logs for regulating water flows during water abstraction and for maintenance of water intake infrastructures. The stop logs and penstocks withstand highest water pressures and have a high load capacity even with hard and bulky debris in the water.

HUBER expands activities in the field of water extraction: clean water through innovative system solutions for seawater and river water extraction

Increasing population density as well as developments in industrial, commercial and agricultural sectors pose ever greater challenges for secure water supply. Increasingly, seawater and river water are being extracted to meet the growing demand.

HUBER extends its range of coarse screen systems with the HUBER Grab Screen TrashLift

Coarse screens are the protective equipment of a screening system. Their task is not removing the incoming screenings from the water flow, but coarse screens are used to protect downstream finer screening systems (or machine technology in general) in the event that massive amounts of coarse material or extreme-size debris occur.
