Aerobic wastewater treatment with the activated sludge process

„Wastewater is any water that has been adversely affected in quality by anthropogenic influence. Municipal wastewater is usually conveyed in a combined sewer or sanitary sewer, and treated at a wastewater treatment plant. Treated wastewater is discharged into receiving water via an effluent sewer. Sewage is the subset of wastewater that is contaminated with feces or urine….

The activated sludge process is a process for biological wastewater treatment in sewage treatment plants. Here, the most municipal waste water is thus cleaned by the metabolic activity of aerobic chemoorganoheterotrophen microorganisms, the so-called activated sludge, largely clean of organic impurities….

The substances contained in the raw waste water serve the bacteria in the activated sludge as food, and for processing the bacteria need oxygen, which is fed via the aeration.”

While the traditional communal wastewater treatment in Austria relies on static dimensioning tools and is dominated by civil engineers and the civil construction industry, EnviCare® Engineering GmbH prefers to work with process models for selected, adapted and optimised systems for each particular case.

Long experience is the basis for successful projects

We make use of process modelling based on the ASM and ADM models and innovative membrane separation technology for more than 15 years. Therefore we can rely on a wealth of experience from the design of various types of activated sludge processes. Plants for the treatment of municipal wastewater, landfill leachate, fruit juices, dairy products and biodiesel were planned, supervised during construction and optimised during operation.
