Effective, simple, economical: CarboPlus® eliminates micropollutants entirely



VIEWPOINTS


Paul Manceau

Chairman of the Ouest de Cholet region SIAEP

“As a drinking water supply concession holder, we had two goals: to improve the treatment of organic matter and to treat micropollutants, especially pesticides. This meant ensuring that plant operation was totally safe by adding a module to cope with pollution peaks in the Sèvre Nantaise river from which the plant draws its water.
With CarboPlus®, Stereau was able to offer a tailormade solution that allowed us to address both issues at once, and act ahead of the forthcoming legislation on micropollutants. So we see it as an investment in the future”.


Jean-Michel Belz

Chairman of SIVOM Auray-Belz-Quiberon

“In addition to activated sludge treatment and membrane filtration, we’ve installed a CarboPlus® activated carbon reactor to eliminate micropollutants. Our Kerran wastewater treatment facility is therefore able to cope with the emerging new challenge posed by micropollutants.
As a result, it provides an essential link in protecting aquatic environments and local businesses over the long-term future”.

Pesticides, biocides, detergents, drug residues… Molecules resulting from all kinds of human activity are now detectable at trace levels in water resources. The concentrations may be low, but this multiplicity of molecules poses a potential risk to human health and the environment. Developed by Stereau, CarboPlus® eliminates a very broad spectrum of micropollutants at low cost by adsorption using activated carbon. Neither concentrated nor converted to toxic by-products, the undesirable molecules are completely removed from the water with zero risk of uncontrolled re-release.

 

Simplicity: a single reagent and automated operation

The CarboPlus® reactor works with no need for electromechanical equipment, because the water and carbon separate by gravity. New carbon is injected automatically in concentrations matched to the quality of water to be treated.

 

Economy: compact and energy-efficient

Simultaneously a contact and separation reactor, CarboPlus® is exceptionally compact. Located upstream of the final filtration stage, the process is easily installed in new or existing treatment units. CarboPlus® consumes little energy, and operates successfully with a broad range of activated carbons.
Versatility: guaranteed effective for drinking water, wastewater and industrial effluents
Whether it is used to ensure the health safety of drinking water, protect the natural environment or control the environmental impact of an industrial plant, CarboPlus® is designed for ‘bespoke operation’. Every project is run by a team of specialists, from design through to operation.

Micropollutants in wastewater and the natural environment

Wastewater: urban wastewater treatment plants discharge between 5 and 10 micrograms per litre of drug residues*.
*Panel analysed: Carbamazepine, Oxazepam, Diclofenac, Ibuprofen, Furosemide, Sulfamethoxazole, Propranolol and Atenolol

Drinking water: the main micropollutants present in water resources are pesticides. They have been identified at 91% of French watercourse quality monitoring points (including the French overseas departments), 75% of open water monitoring points and 70% of groundwater monitoring points.

According to a 2011 assessment published by the Department of the Commissioner-General for Sustainable Development in France.
