Thanks to their unique design featuring a cylinder and a doctor blade at the core of the system, Idrascreen units effectively treat the inlet water, leaving only the solids on the external surface of the cylindrical screen. Furthermore, Idrascreen units are equipped with an inner low/medium pressure washing system consisting of nozzles that provide periodical cleaning. This feature prevents clogging issues and significantly reduces the need for cleaning maintenance, leading to cost savings. ### How Idrascreen works The effluent to be screened is introduced into the headbox, which is purposefully designed to slow down the flow rate and ensure even distribution. From there, the effluent overflows a sealed weir and enters the rotating cylindrical screen. As the effluent passes through the screen, solids are retained on its external surface and subsequently removed by the doctor blade. Following this, the screen effluent provides a backwashing process while passing through the cylinder. This backwashing action effectively cleans the screen openings, ensuring the section of the screen cylinder to be fed remains clean at all times. Furthermore, the backwash process helps prevent the formation of mucilage inside the cylindrical screen. [Do you have a question about this technology?

Additionally, the Idrascreen can be equipped with a special movable blade scraper and customized for specific installations, allowing it to be directly installed on the channel for enhanced efficiency and convenience. ### Features and benefits ![](/sites/g/files/dvc4591/files/styles/default/public/image/2023/01/Footprint-picto1.png.webp?itok=m1DT26wx) Small footprint ![](/sites/g/files/dvc4591/files/styles/default/public/image/2023/09/Sludge-management-picto-new.png.webp?itok=_DOJuBAO) Efficient dry product separation ![](/sites/g/files/dvc4591/files/styles/default/public/image/2023/02/Water-picto.png.webp?itok=sTEssWJ3) Self-cleaning ![](/sites/g/files/dvc4591/files/styles/default/public/image/2023/02/Maiintenance-1.png.webp?itok=ubVODCHf) Long life with little or no maintenance ![](/sites/g/files/dvc4591/files/styles/default/public/image/2023/02/Cost-efficiency-picto.png.webp?itok=_SzM96y6) Low installation and operating costs ![](/sites/g/files/dvc4591/files/styles/default/public/image/2023/02/Electricity-consumption.png.webp?itok=9CK7ZxD_) Low power consumption ## Applications [ ![Two workers wearing helmets, masks and gloves in a wastewater treatment plant. © Médiathèque VEOLIA - Jérôme Sevrette / ANDIA](/sites/g/files/dvc4591/files/styles/content_push_teaser/public/image/2022/05/VEOLIA_StJeanLaPoterie_JeromeSevrette_Andia_52.jpg.webp?itok=FOiUSMwe) ](/en/applications/industrial-wastewater-treatment "Industrial wastewater treatment") [Industrial wastewater treatment](/en/applications/industrial-wastewater-treatment "Industrial wastewater treatment") Technologies, services and process expertise to meet environmental requirements, remove contaminants and transform wastewater into a resource.

It is a very simple product, but at the same time innovative, robust, easy to use and extremely reliable. ![](/sites/g/files/dvc4591/files/styles/default/public/image/2023/09/SILVESTRI_Giovanni-New1.jpg.webp?itok=gVCgSgIf) #### Giovanni Silvestri International Sales Director - Veolia Water Technologies Italy **Contact Giovanni through his** [**LinkedIn account**](linkedin.com/in/giovanni-silvestri-61844562) ## FAQ about Idrascreen™ ### What is water screening? Screening is a wastewater pretreatment and solids separation technique to keep out impurities and particles contained in the wastewater from entering the water treatment system, which would make it less effective. Water screening is classified in three main categories: fine screening, medium screening and coarse screening. The solids get trapped by inclined screens or bar racks but in the case of Idrascreen it is a rotating cylindrical screen which makes it more effective. ### What is the difference between screening and filtration in water treatment? Water screening is the very first phase in the wastewater treatment process in order to remove large organic matter while filtration is the second phase that contributes to further removing any remaining impurities. These two phases are complementary and needed to achieve effective water treatment. ### What category of water screening does Idrascreen belong to? The Idrascreen is a fine screening unit dedicated to wastewater pretreatment and solids separation in many industrial or municipal applications. ## Case Studies ![](/sites/g/files/dvc4591/files/styles/show_case_card/public/image/2023/09/Idrascreen-case-study.png.webp?itok=1zhOulDx) South East Asia South East Asia - Brewery A leading producer of alcoholic and non-alcoholic beverages in South East Asia, uses Idrascreen to treat the wastewater coming from its beer production process which needs to be screened to separate larger particles such as spent grains, paper labels and plastics before it goes for aerobic and anaerobic wastewater treatment with a second Veolia technology, Biothane®. ## Technologies related to Idrascreen [ ![](/sites/g/files/dvc4591/files/styles/vwt_product_content_push/public/image/2019/02/Idraflot-push.jpg.webp?itok=IcN6xOJP) ### Idraflot™ Highly compact and innovative modular flotation units to achieve the highest removal efficiency on suspended solids, oils and grease, and insoluble chemical oxygen demand (COD).
