Our Projects

VorTech have a numerous different projects that have covered a range of deployment options, including municipal WWT, industrial WWT, aquaculture and CFD analysis on a variety of different systems involving vortex drop shafts, reservoirs, wind flow modelling in build environments and aeration and mixing devices at WWTPs. See some of the projects undertaken below.

Pilot Municipal WWTP – Ireland

The VPA-S1 system was initially trialled at a small Irish municipal WWTP with a population equivalent (PE) of ~267.5. The system performed excellently throughout exhibiting excellent oxygen transfer and the activated sludge system with VPA treating the wastewater very efficiently.

VPA type: VPA-S1
Location: Ireland
Configuration: CMAS/SBR
Installation type: New build
Wastewater type: Municipal
PE: ~267.5

Municipal WWTP – Ireland

The VPA-S2 system was retrofitted onto the aeration tank at an Irish municipal WWTP. Two 6 VPA-S2 units were deployed to the WWTP which has a PE of circa 2,600.

Industrial WWTP – United Kingdom

The VPA-S5 system was installed at an abattoir in the UK for aeration at the site. The system was installed as part of a new build.

VPA type: VPA-SS
Location: United Kingdom
Configuration: CMAS
Installation type: New build
Wastewater type: Industrial (Abattoir)
PE: 14,000

Aquaculture site – Ireland

There was a VPA-S2 system installed at an aquaculture site in Ireland. The system was tested at the site to determine its effectiveness in these settings. The system exhibited great potential for deployment in this sector.

CFD – Oxidation ditch

As part of an aeration energy audit the VorTech team performed CFD modelling on an oxidation ditch at a WWTP in Ireland. Development of the model allowed the team to determine the mixing requirements and velocity profiles throughout the oxidation ditch, so that adequate mixing could be provided when retrofitted with VPA aerators to replace the legacy horizontal brush aerators that were in-situ.

By developing a model, the team were able to determine the exact effects that changing the mixing devices would have and identify any potential issues allowing them to be resolved prior to building, saving on costly modifications that could be required if CFD analysis was not performed.

Hybrid Physical and CFD Modelling: CSO intercept structure

VorTech use physical models to validate the accuracy of CFD models and predict performance at full scale.

Once a physical model has been constructed and compared to the CFD model, the numerical model can then be refined in order to maximise the value and accuracy of the model. This can reduce cost and time that can be required when constructing the physical structure.
