[ Product listing ](/en/solutions/technologies " Product listing") #### Actiflo® Duo is a two in one ready-to-use system designed to adjust to substantial fluctuations in wastewater flows to be treated. [CONTACT AN EXPERT](https://www.veoliawatertechnologies.com/en/contact) [Overview](#1) [Product range and resources](#2) ## Overview Actiflo® Duo can operate as a Multiflo® format (or conventional lamella clarifier) in times of low flow, such as in dry weather, or as an Actiflo®, i.e. coagulation/flocculation and settling ballasted with microsand in times of high flow, such as in wet weather. This high operational flexibility in treatment operation is also especially important in managing excess flows during periods of heavy rainfall. ![](/sites/g/files/dvc3601/files/styles/default/public/image/2018/12/Actiflo-duo-scheme-EN.jpg.webp?itok=C32iWN1W) ### Benefits - Exceptional treatment performance regardless of field of application. - Operational flexibility - Optimization of installed equipment at lower operating costs. - Lower civil engineering costs thanks to process compactness. - Easy-to-use process: simply operation demanding little attention from operators. ### ### Applications Wastewater primary, secondary and tertiary treatment ### Some References - Illawarra, Sydney, Australia, 2006, 160 000 m3/day, CSO-120m/h treatment - Hartevann (Bykle), Norway, 2011, 5 800 m3/day, secondary treatment, MBBR-70m/h clarification - Tranemo, Sweden, 2004, 12 000 m3/day, CSO-89m/h tertiary treatment - Port Clinton, USA, 2004, 91 000 m3/day, CSO - 88m/h primary and tertiary treatment - Danang Beach Resort, Vietnam, 2011, 13 000 m3/day, secondary treatment /MBBR - 110m/h clarification ## Product range and resources Product range [ ![actiflo mini hero banner](/sites/g/files/dvc3601/files/styles/vwt_product_content_push/public/image/2020/01/ACTIFLO%20MINI%20left%20view.png.webp?itok=kxnChHdy) ### Actiflo® Pack Mini A very compact and fully standardized clarifier package plant used for various applications such as drinking and process water, municipal and industrial wastewater and reuse.
