#### BIOACTIFLO™ is a process designed for treatment of stormwater and reduction of its soluble BOD. [OTA YHTEYTTÄ ASIANTUNTIJAAN](https://www.veoliawatertechnologies.fi/fi/ota-yhteytta) [Overview](#1) [Product range and Resources](#2) ## Overview In periods of heavy rainfall, water flows entering a treatment plant may may exceed its full wet weather capacity thereby preventing it from attaining the discharge quality standards required by local legislation. BioActiflo has been specifically designed to address this issue and provide additional biological treatment when the need arises. It involves a biological treatment - in a pre-contact tank, polluted water (BOD) is treated by activated sludge - followed by a high-performance secondary clarification: Actiflo®. This solution helps to cut down phosphorus, 60 to 80% of soluble BOD, and 85 to 90% of total BOD. It equally helps to maintain the integrity of the main treatment plant while avoiding sludge overflows.  **BENEFITS** - High performance: pre-contact tank: 10 – 20 min combined with an Actiflo - Treated effluents comply with EPA (USA) discharge standards for suspended solids and BOD - Ideal solution for «online» treatment of stormwater in combined sewer systems - Highly economical with low footprint - Effluent quality guaranteed even with high flow fluctuations **APPLICATIONS** - Stormwater treatment **PERFORMANCES**  **SOME REFERENCES** - Wilson Creek, Lucas, Texas, USA, 2012, 121000 m3 /day. Tertiary and SSO treatment - clarification velocity: 75m/h - St. Bernard, LA, USA, 2012, 30000 m3 /day SSO treatment - clarification velocity: 95m/h ## Product range and Resources Product range [  ### Actiflo® Pack Mini The pre-engineered Actiflo® Pack Mini is a very compact standard package plant for drinking water treatment.
