If ground water is the source for your treatment plant and you only require a polishing step to reduce PFAS concentrations, Veolia offers cost effective standard solutions such as activated carbon pressure filters and ion exchange systems to accomplish this. If your ground water source has other areas of concern in addition to PFAS such as hardness, nitrates, perchlorate, organics or is under the influence of surface water, Veolia can provide a complete system for your total treatment needs.
If surface water is the source for your treatment plant, Veolia offers a wide range of pretreatment and post-treatment technologies to address all of your PFAS treatment needs.
If needed, Veolia can deploy mobile treatment units to maintain water production while source water management and treatment technology evaluations are conducted.
Testing by Veolia
Conventional water and wastewater treatment processes do not effectively remove PFAS. Veolia offers a range of customized solutions based on individual water source demands. Bench scale and/or pilot testing can be done in order to determine a treatment configuration best suited for the type and concentration of PFAS, the presence of other contaminants and organics in the source water, and the desired quality of the treated water.
Mainstream ANITA™ Mox
For mainstream deammonification, ANITA™ Mox provides an easy and purely mechanical solution to securely retain anammox biomass with the combination of biofilm carriers and retention sieves. This fast and robust physical separation between anammox-rich biofilm carriers and nitrifier-rich suspended sludge allows for easy control of the sludge and therefore better selective wash-out of NOB while retaining anammox.
Compared to conventional BNR treatment, mainstream ANITA Mox™ reduces aeration demand by 60% and eliminates the need for carbon addition. Minimizing the operating cost of nitrogen removal and generating power through COD diversion, Mainstream ANITA Mox™ makes it possible for facilities to achieve energy neutrality.
- 60% Less Aeration Required
- No External Carbon Addition
- 90% Ammonia Removal
- Power Generation through COD diversion
- Reduced Footprint
- Robust Media Based Process
Hydrotech for Primary Treatment
In addition, Hydrotech filters offer great flexibility for control of loading (BOD, COD and TP) to downstream biological treatment processes. As a result of the excellent capability to remove organic matter and phosphorus, Hydrotech filters can also be applied in process configurations where subsequent biological treatment isn't required, such as storm water treatment.
Primary Filter vs Primary Clarifier
- Compact (up to 90% less than conventional)
- TSS reduction ~50% up to 95% depending on design (with or w/o chemical addition)
- Lower energy costs due to reduced load on secondary treatment
- Increased solids capture for energy recovery
- Flexibility to control organic load to biological treatment
- Phosphorus removal capability
- Easy to install, operate, and maintain -> user friendly!
- Covered for reduced odor
- Can be used for a cariety of applications (primary, wet weather, CSO/SSO, etc.)
Actina™ Pellet Softening
To soften hard water, Veolia Water Technologies has developed Actina™, a pellet reactor process tailored to municipal drinking water softening. By reducing calcium hardness, Actina™ allows municipalities to enhance the asset management of their distribution network while preventing negative impacts on the end users. This solution also allows a significant reduction of impacts on downstream on-site or centralized wastewater treatment.
The Actina™ process is based on the pellet softening principle, which consists in modifying the calcium-carbon equilibrium in the water to be treated. Soda or lime injection is used, causing limestone crystallization on the sand.
- Compactness, simplicity and reliability of operation
- Robustness and additional barriers against iron, manganese and metals
- No limit on calcium hardness removal - media regeneration not required
- Energy savings - unlike an electric carbonate removal system
- No associated sludge treatment needed
- No brine to dispose of
