Actiflo - Veolia Water Solutions & Technologies

Actiflo®: a versatile range of usesDrinking waterActiflo® applies to both surface and ground waterwhere improved performance and/or capital costreduction is desired.It is ideally suited for thetreatment of:> rapidly fluctuating watersources,> low temperature water (1°C),> reservoir water with very lowturbidity,> sea or brackish water.Through the use of Actisand TM , Actiflo® achievesbetter performance than all existing clarificationprocesses, displaying consistent removal of:> turbidity, colour, total organic carbon (TOC),> algae, particle count, pathogens, cryptosporidium,> oxidised iron, manganese and arsenic...Actiflo® is particularly efficient to remove taste andodour associated with algal bloom. It can also be usedfor the recovery of backwash water from rapid gravityfilter thus reducing water loss and running costs.WastewaterActiflo® can be used in most municipalapplications:> primary settlement: due to the mass ofmicrosand constantly in the process, Actiflo®handles very swift raw water qualityvariations and rapid flow changes;> treatment of biofilter backwash water: dueto its short residence time, the biologicalsludge is unlikely to go septic; it is thereforeclarified extremely efficiently, with superiorlevels of treatment compared to flotation;> clarification of trickling filter effluents, inreplacement of a conventional clarifier;> storm water treatment (combined sewer overflow): Actiflo®treats storm peak flows as they occur. In combination with UVdisinfection (Actistar), it delivers an effluent compliant withthe most stringent bathing and shellfish water directives;> tertiary polishing or phosphorus removal: whether it is usedfor suspended solids, colour or phosphorus removal, Actiflo®meets or exceeds water quality standards with removal ratesusually higher than 90%. The same Actiflo® unit applies tostorm flow treatment in peak flow and to tertiary treatmentin dry flow conditions, with a significant removal of hormones(endocrine perturbators) for the latter;> water reuse for crop irrigation or aquifer recharge, in combinationwith Discfilter and UV disinfection (Actidisc Plus).Industrial water and effluentsActiflo® is an idealsolution for the recyclingof process waterand pre-treatment ofboiler feed or coolingtower make-up water.Similarly it treats anytype of process wateras well as most industrialeffluents.> solids and colour removal: prior to membranetreatment, reverse osmosis (Actimem), or incombination with Discfilter (Actidisc), to produceprocess water for the pulp and paper or food industry;> removal of heavy metals (lead, cadmium, zinc…)and ashes from power plant and steel milleffluents, or polishing treatment to removesuspended solids and associated pollutants;> lime soda softening (Actisoft) for the productionof demineralised water.
