Software & Consulting

    Welcome to BITControl GmbH

    Over 20 years, BITControl has been developing software for the design of wastewater treatment plants and for efficient plant operation.

    The extraordinary combination of engineering, software and programming, procedural competence and a partnership with all parties involved, lead us to very good and efficient project results.

    Our mission statement is a comprehensive service concept for all projects, which supports our customers from planning to optimal operation.


    Recertification ISO 9001:2015

    Already in 2014 BITControl has introduced a quality management system. In June 2020, the repeated recertification by TÜV Rheinland took place. The auditor certified that we adequately maintain and implement an effective QM system that meets the requirements of ISO 9001:2015.



    New version of the proven design software AQUA DESIGNER now available
    New Price Model for Short-Term Use (30d, 365d)

    AQUA DESIGNER is one of the standard design programs for activated sludge plants in Germany and worldwide. The range of tools has been extended over the last few years to all important procedures and procedural stages.

    New in AQUA DESIGNER 9.1:


    aquadesignerMembrane System according to DWA-M 227
    New functions: Machine list, Measuring Point List and Flow Diagram

    AQUA DESIGNER has been on the market for 20 years and is one of the few design tools for sewage treatment plants that has been continuously adapted to the current DWA guidelines. After a version with the new DWA-A 131 of June 2016 was already available in 2016, which is also integrated into the SBR design, the DWA-M 229-1 of September 2017 was also added in spring. At the end of 2018, valuable additional engineering tools were completed.

    Schulung IrakExchange of experience with Iraq

    On 28 and 29 September 2018, a training on the design software AQUA DESIGNER and the basics of wastewater treatment took place in the BITControl rooms. The training was carried out by Dipl.-Ing. Norbert Meyer for a wastewater expert from Iraq. This also resulted in a lively exchange of experiences.

    New References for Design Software


    aquadesignerAQUA DESIGNER is one of the common design software for activated sludge systems. Over the last few years, the range of tools has been extended to include all important processes and process stages. AQUA AERO, on the other hand, concentrates on the process engineering design of the aeration technology. With the calculation of investment, reinvestment and operating costs the economical calculation covers the whole life cycle of the project.

    Focal points were:

    DIN EN ISO 9001:2015

    Conversion to ISO 9001:2015 successfully implemented

    CertificateBITControl changed the quality management system to the current ISO 9001: 2015 standard in April 2018. The certification was carried out by TÜV Rheinland. In advance, the mission statement, policy and strategy were adapted. We have analyzed and partially revised all processes. So we are even closer to the requirements of the customer and other interested parties. Even though the certification in our business is rather uncommon, we are sure that the QM system will set standards and improve our services.

    New Wastewater Treatment Plants for Lagos

    Two SBR plants for 6,000 and 36,000 PE are planned by BITControl for the Lagos State Wastewater Management Office. The implementation of the system is accompanied by an intense schooling of the engineers of the LSWMO.

    Here is the detailed report.

    In October 10 employees of the agency got a schooling for the software AQUA DESIGNER in our office in Nattenheim.

    By the schooling also generel treatment themes have been discussed and we made some excursions to local plants like an MBR for 7.000 PE or a recently by BITControl optimized plant with plate diffusers, fuzzy-control and a new block heat and power plant.

    Waste Water Management Office of Lagos, Nigeria purchased a company license of AQUA DESIGNER

    Logo LagosIn April 2014 the Lagos State Waste Water Management Office purchased a company license of the wastewater design software AQUA DESIGNER. With AQUA DESIGNER the new plants for Lagos will be calculated and verified.

    With AQUA DESIGNER various processes for contineous flown plants with separate stage denitrification, intermittend denitrification or simultaneous denitrification and also for carbon degredation or only nitrification can be calculated. Also the design of SBR or MBR plants is concluded. Furthermore other parts of the plant like sludge treatment and grit chamber are part of the design tools.

    As result you get detailled reports, operational cost, key figures, drawings etc.
