Our Projects

VorTech have successfully delivered solutions on numerous projects covering a wide range of deployment options, including municipal WWT, industrial WWT and aquaculture. We have also delivered expert CFD analysis and insights 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.

Municipal WWTP – UNITED KINGDOM

8 x VPA-S5040 systems were retrofitted to 4 x 60 year old oxidation ditches at a 120,000 PE wastewater treatment plant. The purpose of the upgrade was to reduce total lifecycle costs (energy and maintenance) reduce noise pollution and enhance safety of operations.

VPA Type: VPA-S5040
Location: United Kingdom
Configuration: Oxidation Ditch
Installation type: Retrofit
Wastewater type: Municipal
PE: 120,000

Industrial WWTP – Ireland

2 x VPA-S1010 systems were retrofitted to 2 membrane bioreactors (MBRs) treating industrial waste from carbonated beverage production. The purpose of the upgrade was reduce energy intensity (which resulted from existing diffuser fouling issues) and eliminate
costly and unsafe tank draining processes for maintenance.

VPA type: VPA-S1010
Location: Ireland
Configuration: MBR
Installation type: New build
Wastewater type: Retrofit
PE: 4,000

Municipal WWTP – Ireland

The VPA-S3 system was retrofitted onto the aeration tank at an Irish municipal WWTP. 1 x VPA-S3020 unit was deployed to the WWTP which has a PE of circa 3,333.

VPA Type: VPA-3020
Location: Ireland
Configuration: CMAS
Installation type: Retrofit
Wastewater type: Municipal
PE: 3,333

Industrial WWTP – United Kingdom

The VPA-S6063 system was installed at an abattoir in the UK for aerobic and anoxic treatment at the site’s activated sludge facility. The system was installed as part of a new build.

VPA type: VPA-S5
Location: United Kingdom
Configuration: CMAS
Installation type: New build
Wastewater type: Industrial
PE: 19,000

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.
