ACTIFLO® CARB<br />

Optimal Treatment<br />

For <strong>Water</strong> Purification<br />
and Polishing<br />
High efficiency treatment<br />
To meet the ever more stringent<br />
requirements in terms of water quality,<br />
<strong>Veolia</strong> <strong>Water</strong> <strong>Solutions</strong> & <strong>Technologies</strong> has<br />
developed and launched a new and exclusive<br />
application: Actiflo® <strong>Carb</strong>.<br />
Designed to further enhance water treatment, the<br />
Actiflo® <strong>Carb</strong> process combines the rapid flocculation<br />
and settling performance of Actiflo® with the<br />
adsorption capacity of Powdered Activated <strong>Carb</strong>on<br />
(PAC) with the aim of eliminating compounds that are<br />
not removed in the clarification process.<br />
The adsorption properties of PAC offer an efficient<br />
solution for removing non-flocculable Natural Organic<br />
Matter (NOM), micro-algae, pesticides and emerging<br />
micro-pollutants present in the water to be treated.<br />
The unrivalled performance offered by Actiflo® <strong>Carb</strong><br />
makes it possible to produce very high quality water.<br />
The Actiflo® <strong>Carb</strong> process<br />
The operating characteristics of the Actiflo® <strong>Carb</strong><br />
process are the same as for Actiflo®, including all<br />
the advantages of fast and high treatment<br />
performance. In addition to the coagulation,<br />
flocculation and settling tanks, Actiflo® <strong>Carb</strong><br />
features a PAC pre-contact tank for the adsorption<br />
of pollutants.<br />

ACTIFLO® CARB<br />
Powdered Activated <strong>Carb</strong>on has a micro<br />
porous structure that physically adsorbs<br />
water pollutants. Those compounds to<br />
be eliminated are trapped in the PAC<br />
micro-pores which offer a very large<br />
specific adsorption surface area.<br />
Being an integral part of the Actiflo®<br />
<strong>Carb</strong> process, PAC ensures a high<br />
elimination efficiency of pollutants,<br />
hence contributing significantly to the<br />
improvement of water quality.<br />
For its Actiflo® <strong>Carb</strong> technology, <strong>Veolia</strong> <strong>Water</strong> <strong>Solutions</strong><br />
& <strong>Technologies</strong> recommends using the PICAHYDRO AFP, PAC series<br />
designed and developed by its own subsidiary PICA. Made from<br />
100% renewable and sustainable raw materials, PICA’s PAC series<br />
offers the best performance for the elimination of pollutants.<br />
Applications<br />
Actiflo® <strong>Carb</strong> is recommended for:<br />
• Drinking water, for enhanced removal of NOM, pesticides,<br />
emerging micro-pollutants, micro-algae as well as taste<br />
and odour<br />
• Process water, for NOM treatment and water polishing<br />
• Wastewater, for the removal of compounds that cannot<br />
be eliminated by biological treatment<br />
• Reuse, for tertiary treatment and effluent polishing<br />
Actiflo® Twin <strong>Carb</strong>, a two-stage<br />
treatment process<br />
Depending on raw water quality and the performance levels<br />
to be achieved, Actiflo® <strong>Carb</strong> is also available in the Actiflo®<br />
Twin <strong>Carb</strong> configuration.<br />
This unique set-up consists of two treatment units operating<br />
in series to maximize NOM removal while reducing the<br />
installation footprint. Actiflo® Twin <strong>Carb</strong> consists of a first<br />
clarification stage (Actiflo® or Actiflo® Turbo) followed by a polishing<br />
treatment stage (Actiflo® <strong>Carb</strong> or Actiflo® Turbo <strong>Carb</strong>).<br />
Especially suited to treat water with a high load of pollutants,<br />
Actiflo® Twin <strong>Carb</strong> makes it possible to reduce the Total Organic<br />
<strong>Carb</strong>on (TOC) content in raw water from 15 mg/l to 2 mg/l<br />
or less.<br />
ACTIFLO® CARB<br />
ADVANTAGES<br />
• Advanced treatment based<br />
on PAC use<br />
• Maximum NOM removal<br />
• Polishing of treated water<br />
• Compatibility with other upstream<br />
clarification processes: Actiflo®,<br />
Actiflo® Turbo, Multiflo,<br />
other clarifiers, DAF, Spidflow…<br />
• High rise rate: ≥ 30m/h<br />
• Very small footprint<br />
• Easy start-up: within a few minutes<br />
• Easy refurbishment of existing<br />
installations<br />
