Patented vortex aeration system by Vortech Water Solutions. Uses kinetic energy to create a highly efficient vortex that transfers oxygen into the wastewater stream with far lower energy consumption than conventional aeration systems — no submerged diffusers, no large compressors.
The VPA™ (Vortex Powered Aeration) is the proprietary technology of Vortech Water Solutions Ltd., developed to overcome the limitations of traditional aeration systems. Instead of submerged diffusers or conventional surface aerators, the VPA creates a powerful hydrodynamic vortex that naturally and continuously mixes air and wastewater.
The circulation chamber and column pump inject air at the system inlet, generating a spiral flow that maximises air-liquid contact and efficiently dissolves oxygen throughout the tank. The result is high-performance biological aeration with a reduced footprint, without the complexity and maintenance cost of traditional fine bubble diffusion systems.
Circular chamber creates spiral flow — maximum air-liquid contact area with no submerged mechanical parts.
Pump speed is automatically modulated to reach and maintain the dissolved oxygen set-point.
Top-mounted pump access hatch allows maintenance without tank dewatering or confined space entry.
Multiple VPA units operate in parallel to meet any project capacity, from small WWTPs to large industrial facilities.
Each component is engineered to maximise aeration efficiency and minimise maintenance requirements
Atmospheric air drawn into the top of the unit — no high-pressure compressor required, leveraging system kinetics.
Upper circular chamber that induces vortex motion, ensuring uniform mixing of air and wastewater.
Guides directed wastewater flow into the circulation chamber, sustaining the vortex.
Axial flow pump integrated into the side column — responsible for circulation and regulating oxygen transfer.
Surface-level access to the pump assembly — no diving or tank dewatering required for maintenance.
Evenly distributes aerated effluent back into the tank, completing the circulation and aeration cycle.
Atmospheric air enters through the top intake of the VPA unit without a high-pressure compressor.
The column pump drives wastewater through the inlet column, creating spiral flow in the circulation chamber.
Vortex motion creates high air-liquid contact surface area, efficiently dissolving oxygen throughout the tank.
Aerated effluent is evenly distributed via the outlet duct, completing the cycle and promoting homogeneous mixing.
DO sensor continuously monitors dissolved oxygen levels and adjusts pump speed to maintain the set-point.
Demand-driven pump modulation eliminates the energy waste typical of fixed-speed aeration systems.
Versatile technology adapted to different biological treatment processes
Replaces or complements aeration systems in municipal and industrial activated sludge tanks, ensuring stable and efficient DO levels.
High-quality aeration for MBR systems — compatible with the stringent DO requirements of membrane bioreactor processes.
Biological treatment of wastewater from food and beverage, pulp and paper, chemical, pharmaceutical, and other high-load industries.
Upgrade existing aerated lagoons with VPA to increase treatment capacity without constructing new tanks.
Replace deteriorating fine bubble diffusers or surface aerators without civil works or extended dewatering.
Modular and compact, VPA adapts to small and medium-sized treatment plants requiring efficient aeration at low operating cost.
Vortech Water Solutions Ltd. is an Irish company specialising in the development of innovative technologies for wastewater aeration. Founded with the purpose of reinventing how oxygen is transferred in biological treatment processes, Vortech developed the VPA™ system — a patented approach that uses hydrodynamic vortex principles to overcome the limitations of conventional aerators.
With reference installations across multiple continents and documented case studies in sectors such as food and beverage, municipal utilities, and process industries, Vortech combines robust engineering with operational simplicity. The company's motto — "Simple. Reliable. Efficient." — encapsulates the philosophy behind the VPA.
