Advanced technologies for the elimination of micropollutants: BIOZONE®, PACOPUR®, CARBOPUR® Discussions regarding micropollutants, substances occurring in very low concentrations (ng/l to μg/l) in water, first commenced around 2000. These micropollutants are mostly not new, but their existence could only be proven with the availability of steadily more effective analytical methodology. Micropollutants include a wide range […]
Efficient Nitrogen Removal (ANAMMOX) from digester supernatant. The separate treatment of the nitrogenous return supernatant from the sludge treatment process constitutes a special application. In this way, the treatment plant’s denitrification performance can be boosted while taking the pressure off the biological treatment stage. Nitrogen can be removed from the return supernatant conventionally by using […]
Adsorption process with granulated activated carbon (GAC) Utilizes the same physical principle as with Powdered Activated Carbon (PAC), but with a larger grain size. This allows it to be placed as a substitute for traditional media in a filter. This means that adsorption and retention of the adsorbent occur in a single process step, making […]
Chemical-oxidative & Biological Treatment. The BIOZONE® process has been developed by WABAG for the treatment of effluent containing a high percentage of organic compounds, which are resistant to biodegradation.  The addition of ozone breaks up the complex compounds of e.g. micropollutants, which thereby lose their harmful effect and can be subsequently partially degraded by […]
Membrane bioreactors (MBR) are powerful systems for the biological treatment of wastewater. The biological treatment stage performs a role similar to a conventional activated sludge system. However, instead of separating activated sludge and clean wastewater in a secondary sedimentation tank by gravity, membrane filtration is employed. As a result, the filtrate contains no solid matter […]
Aerobic Granular Activated Sludge Technology. Granules instead of flocs. NEREDA® is a highly advanced technology for biological wastewater treatment based on the SBR method, harnessing the power of aerobic granular sludge. With this technology, bacteria naturally grow in compact granules instead of in flocs. These granules have excellent settling properties, offering numerous advantages: the biomass […]
The HYBRIDâ„¢ process is based on the conventional two-stage activated sludge process. However, the biozenoses of both stages are not separated but advantageously mixed through two innovative hybrid sludge cycles. The process was jointly developed by WABAG and the Vienna University of Technology. The main advantages are: Process stability: The first process stage provides optimum […]
SBR (Sequential Batch Reactor) is a system for the biological treatment of wastewater. In contrast to conventional activated sludge processes, where wastewater undergoes treatment by passing through a series of tanks, the SBR method involves conducting different steps sequentially in the same tank. As the reactors are filled on a batch-by-batch basis, several SBR tanks […]
FLUOPUR® is WABAG’s moving bed process for the biological treatment of wastewater. It can be used as a moving bed (MBBR) on its own or in combination with activated sludge (hybrid or IFAS). The patented carrier material, developed by WABAG, is used to cultivate biofilms capable of performing various tasks according to requirements. The FLUOPUR® […]
Biofiltration for Wastewater Treatment and Water Reuse. BIOPUR® is a biofiltration system developed by WABAG for the biological treatment of wastewater. It utilizes biofilms, cultivated on solid surfaces, to biologically degrade pollutants in the wastewater, while simultaneously capturing suspended solids with filter materials. BIOPUR® is a modern and space-saving process capable of meeting the toughest […]
