Combined sewer overflow may contain particulate and soluble wastes from domestic sewage, industrial, and commercial wastewaters. These waste products include suspended solids, bacteria, viruses, nutrients, toxic pollutants, oil, and grease and debris, posing significant risks to receiving water quality, public health, and aquatic life.
Veolia applies its Actiflo® process for high rate clarification and removal of total suspended solids and particulate biochemical oxygen demand materials during wet weather conditions.
The Actiflo® effluent typically achieves higher than 90% removal, making flows easily disinfected with UV or chlorination.
The Actiflo® process can be used in parallel with a conventional water treatment plant or at a satellite facility within the collection system.
Offering unlimited treatment capacity, the Actiflo® process allows the elimination of overflows.
Process trains can be used for primary and/or tertiary treatment during dry weather flows.
The effectiveness of Actiflo® in treating wet weather flows has been proven at facilities around the world.
