BITControl Aqua Designer -Â Version 9.2 -WWTP Design Software
AQUA DESIGNER is the planning software for the dimensioning of all treatment stages of a wastewater treatment plant, from pre-treatment to biology and sludge treatment. You can choose from the usual practical variants in terms of design approach, process and construction. Planning is supported by many additional functions. As a result, AQUA DESIGNER provides comprehensive documentation for the approvable design with structures, machines, operating costs and true-to-scale drawings, as well as detailed information on load cases, oxygen yield value, sink line, pipework or mass and buoyancy calculations. AQUA DESIGNER is used worldwide for the planning of new plants and for the expansion and modernisation of existing wastewater treatment plants. The application is available in many different languages.
- Standalone version (single licence). Ideal for offline use
- Demo version available for testing for 20 days
- The download is available directly from our homepage
- The licence is bound to the computer on which the licence is activated. If changes are made to the licensed computer, a licence transfer should be carried out
- The languages English and German are automatically included, other languages are optional and can be activated individually for an additional charge
- ADD-On flow diagram is not included and can be purchased separately at extra cost
- Network-based for utilisation and licensing
- Separate installation (download link will be sent after ordering)
- AQUA DESIGNER NET can be installed on any number of PCs in the network, and the network licence determines how many users can use the program simultaneously
- All available languages are included
- ADD-On flow chart is included
- The software cannot be used if the PC is not connected to the network
With AQUA DESIGNER you can dimension all treatment stages of a wastewater treatment plant, from pre-treatment to biology and sludge treatment - with the dimensioning approaches, processes and designs commonly used in practice.
Planning the Sewage Treatment Plant
A Flow chart guides you through the complete dimensioning of your wastewater treatment plant project with AQUA DESIGNER.
Process Variants
- DWA-A 226:Continuous flow activated sludge plants with simultaneous aerobic sludge stabilisation (06/2022)
- DWA-A 131: Dimensioning of single-stage activated sludge plants (06/2016)
- DWA-M 210: Activated sludge plants with sequencing batch reactor operation (07/2009)
- DWA-M 227: Membrane Bioreactor Process (MBR)

Here too, different variants can be calculated for the secondary clarifiers:
- vertical or horizontal flow
- round or rectangular pools
- basin with flat bottom or hopper tank

The calculation form for horizontal flow secondary sedimentation shows the connection between dimensioning and structural and technical design. When you define your structure after determining the minimum parameters, the design values are automatically adjusted to the dimensions actually selected. The center inflow building is also calculated for your selection. For all structural calculations, you are supported by true scale drawings.

- The calculation of the biological stage offers many variants:
- Carbon degradation
- Nitrification
- Denitrification: upstream, intermittent, combined, simultaneous, cascade denitrification
- P-precipitation
- External carbon dosing

Aeration is the heart of every biological treatment. The design for Different load cases and the selection of the appropriate blowers, mixers and aerators is therefore possible in AQUA DESIGNER in great detail. Machines and aerators can be selected from Databanks. The Arrangement of the aerators and agitators in the tank is graphically supported.


The MBR method can be calculated on the basis of DWA-M 227. Here too, Databanks for membranes, aerators, pumps and mixers are available.

With AQUA DESIGNER you can dimension all treatment stages including sludge treatment in accordance with DWA-M368.
- Dimensioning of primary clarifier and static thickener
- Digestion stage with gas, electricity and heat production
- Load and volume balances for turbid water and solids
- Consideration of internal cycles
- Income from the utilisation of digester gas in accordance with the EEG

Even smaller systems, e.g. Compact Systems can be calculated very well with AQUA DESIGNER. The automatically generated true scale drawing is very useful to get an idea of the dimensions and proportions. The scale drawing can also be used to recognise whether the equipment, fits well into the building.
