Oxidative removal of pesticides and VOC. Ground and surface water are frequently subject to organic pollutants such as pesticides and chlorinated hydrocarbons. In order to prevent health risks strict legislation has been passed. “ADOX” stands for “ADvanced Oxidation” and represents a process which leads to the mineralization of organic pollutants in water by OH-radical oxidation. […]
BIODEN® is one of the WABAG-developed biological process for ground water denitrification. The process functions according to the principles of heterotrophic, biological denitrification with ethanol or acetic acid as a carbon source. Basically, it consists of nutrient dosage, a biological filter, subsequent aeration for oxygen enrichment, downstream flocculation filtration and final safety disinfection. The BIODEN® process […]
Water and Wastewater filtration for Drinking and Process Water, for Tertiary Treatment and Water Reuse. Filtration is one of the key processes involved in the treatment of water. The history of rapid filtration can be traced back to the late 19th century but has undergone continuous enhancement ever since. wastewater filtration started in the 1970s. […]
Ceramic Membrane Filtration With a pore size of around 0.1 µm, the ceramic membrane operates in the microfiltration range. This means that large quantities of water can be filtered per m² of membrane surface. When combined with flocculation or oxidation, the degree of separation that can be achieved is similar to that of ultrafiltration. The […]
Ceramic membranes combined with Ozone What makes the ceramic membrane unique is the nature of the material. In contrast to “normal” (organic) membrane fibers, which are quickly destroyed by ozone, ceramic membranes respond positively to any residual ozone in the water: the ozone contained within the water minimizes the fouling potential on the membrane surface. […]
The Compact Solution Developed by WABAG in the 1980s, the lamella settler technology was designed to significantly reduce the footprint of clarifiers following the flocculation and coagulation treatment steps. Since its inception, WABAG’s lamella clarifiers have been successfully implemented in numerous drinking water production and wastewater treatment plants worldwide. The Process In the lamella […]
The electrodialysis process enables specific, partial desalination and has been employed for many years for the desalination of sea- and brackish water. On this basis, in co-operation with the Vienna University of Agricultural Sciences, WABAG has developed the ENR®-process for the denitrification of groundwater. The process: During electrodialysis, salts are separated via ion exchanger membranes […]
OZONE/AOP + Granular Activated Carbon. The perfect couple. WABAG has been using this combination of processes in its multi-barrier systems for decades. The ozone fully or partially oxidizes the micro-pollutants and makes other dissolved matter more easily biodegradable. These substances, any reaction products created through ozonation, and other micro-pollutants are reduced to harmless concentration levels by […]
Adsorption by Powdered Activated Carbon (GAC) / + Membrane Filtration Adsorption by Powdered Activated Carbon (PAC) relies on the prerequisite that the target substance(s) must be absorbable. The process entails introducing finely ground carbon into the flow and subsequently removing it from the water after a specific contact time. In the context of drinking water […]
Adsorption by Granulated Activated Carbon (GAC) / + Membrane Filtration 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, such as the WABAG Flap Valve Filter. This means that adsorption and retention […]
