Highly efficient and capable of generating very high quality effluents, aerobic biological wastewater treatment processes were once the solution used to treat most types of industrial wastewater. Nowadays, with much more emphasis on energy efficiency and minimization of residues (i.e. waste sludge), they are mainly limited to diluted industrial wastewater and municipal applications, and as a polishing step after anaerobic treatment.
However, with strict discharge requirements, it is still impossible to develop a complete biological treatment for any type of wastewater without the use of at least one aerobic stage. Therefore, our technology portfolio also includes many different aerobic treatment systems. Thus, we can offer you a complete range of wastewater treatment solutions capable of meeting any discharge requirement.

In the processes of aerobic biological treatment, organic pollution is converted into carbon dioxide and water. The process requires active aerobic biomass and significant oxygen supply to the reactor for treatment. The disadvantage is that the supply of the required oxygen is often very energy intensive, especially when it comes to concentrated industrial wastewater. Another disadvantage is the significant production of excess sludge that must be controlled and eventually disposed of.
AEROBIC TECHNOLOGIES FROM GWE
ACTIVOX ™ Traditional Activated Sludge System
GWE’s traditional ACTIVOX ™ activated sludge system is applicable to most standard aerobic treatment scenarios. The basic package consists of an activated sludge stage with final clarification and a sludge recirculation line. The system is simple and reliable to operate.
Technology: secondary treatment, anaerobic polishing of the drain.
FLOTOX Aerobic cleaning with enhanced clarification stage
The Industrad system consists of an aerated tank and a GWE SUPERFLOT- AIR dissolved air flotation plant for sludge separation. Organic pollutants (COD, BOD) and ammonia are removed by aerobic treatment. Depending on the application, the aerobic chamber can be a standard activated sludge or another technology, such as a moving bed bioreactor.
In the SUPERFLOT-AIR, the wastewater/sludge is introduced together with the circulating clean wastewater and air is dissolved at high pressure. The floating sludge is removed with a surface scraper.
Technology: secondary treatment, anaerobic effluent polishing, enhanced effluent clarification.
ASTEROX ™ Advanced multi-stage activated sludge system with nitrogen and phosphorus removal
it is a tailor-made, state-of-the-art activated sludge treatment process. With the use of selectors (bulk sludge control) and a plug-flow design with denitrification options, this process is ideal for treating relatively difficult wastewater requiring nitrogen and phosphorus removal to meet discharge limits.
Technology: secondary treatment, anaerobic polishing of effluent, nitrification / denitrification, removal of nutrients.
SEQUOX ™ Conventional Sequencing Batch Reactor (SBR)
it is a flexible treatment technology ideal for small projects with variable wastewater composition and areas with irregular or seasonal wastewater production. Run as a single vessel or multiple reactors, batch reactor operation allows complete processing in a single vessel. It works in a repeating sequence of filling, aerating, settling and draining. The SEQUOX ™ – 2 system uses two tanks to provide continuous wastewater withdrawal to minimize or eliminate leveling requirements.
Technology: secondary processing, nitrification / denitrification, flexible purification.
CYCLOX ™ Continuous aerobic cleaning SBR
The CYCLOX ™ continuous batch reactor process treats wastewater in three or more activated sludge basins, one of which serves as a settler for several hours of operation, eliminating the need for additional clarifiers. Every few hours a different tank serves as a settling tank, and the flow directions between the pools change. It is the ideal solution for areas with high flows and variable effluent composition or seasonal production.
Technology: secondary treatment, nitrification / denitrification, nutrient removal, highly flexible loads and flows.
MEMBROX ™ Membrane Bioreactor (MBR) System
MEMBROX ™. It is a compact, concentrated form of activated sludge treatment system that uses a membrane filtration stage instead of conventional gravity separation clarification. Applicable to virtually all applications, including biological nutrient removal, our conservative design approach ensures reliable performance and low operating costs.
