Biological Water Treatment Solutions
We handle drinking water treatment and wastewater applications like primary, secondary, wastewater reuse, and stormwater management for municipalities around the country. Industries, too, benefit from our diverse solutions, including physical-chemical treatment, packed bed demineralization, ion exchange, reverse osmosis, and aerobic/ anaerobic biological systems.
SERVICE DETAILS
We provide high-performance water, wastewater, and sludge treatment solutions for any size population and virtually any influent condition. We are involved in every stage of a project, from process design to equipment supply to operations training. Our design engineers look at the entire treatment process to find ways to improve water supply and control pollution economically.
Aeration channel doubled with a clarifier combining energy efficiency & compactness.
Low energy product combining a fine bubble annular aeration channel and a central clarifier with an optimized hydraulic profile. It is a compact work, a high length of water for more operational reliability.
Integrates accessibility and maintenance solutions developed with the operators, including :
Treated water collection through an immersed drilled pipe or through a conventional nozzle with automatic cleaning
Travelling bridge spread over the work for an access in all points along the tank
MBR is a wastewater treatment process (residential and industrial) by ultrafiltration flat sheet membranes. With a huge compact size, it provides a clean effluent quality to answer the most demanding emissions standards or to be recovered for reuse.
MBR combines both a biological treatment using activated sludge and a clarification by immersion of flat sheet membranes. Water to be purified enters into a reactor where it is put in contact with a purifying bacterial mass, before passing through the membranes.
The use of membrane technique allows to have a better control over the separation between water and sludge.
Works with high concentration in membrane tanks up to 15g/L
Suited for installations up to 100,000 PE
Flat sheet membranes have a 0,08 μm nominal
pore size

Process allowing the completion of all treatment phases, successively, within the same tank.
SBR is an activated sludge wastewater treatment process that is compact and designed to treat carboneous, nitrogenous and phosphorous pollutions. It is particularly suitable for discharge in sensitive areas. It is made up of cells which together complete a discontinuous sequential process, where all treatment phases take place in the same tank.
Treated water is discharged during the settling phase using a patented floating decanter.
Reduced footprint up to 40% over classic activated sludge treatment
More than 15 years of experience in SBR

Biological process for the advanced treatment of pollutants in a modular system of fixed cultures.
The MBBR is a biological process with fixed fluidized cultures that keeps the micro- organisms in the reactors dedicated to a specific processing step, thus promoting the development of the purifying biomass. We thereby distinguish pre-denitrification from the elimination of carbon, nitrification and post-denitrification.
Reinforced expertise by 7 years of partnership with HYDROXIL SYSTEM (USA)
