Activated Sludge (ASI)

Activatedsludge.info (ASI) is the brainchild of a group with expertise in a wide range of areas in biological wastewater treatment and a goal to use the web for technology transfer. Members of the team at ASI also have interests and expertise in other areas including software development, wastewater process modelling and on-line education and training.

Biological wastewater treatment is the world's largest biotechnology industry and activated sludge, which is our particular interest, makes up a very significant part of that industry. Over the forthcoming months you will see new articles on relevant and diverse aspects of activated sludge.

activatedsludge.info is the place to come for information on new developments, processes and technologies in activated sludge, as well as providing a fresh look at established topics. We also welcome your input, tell us about the topics you would like to see and we will do our best to put them in place, either from our own resources or from our colleagues around the world.

With our experience in environmental engineering and process operations, we developed this site as a portal, through which we can inform and update. So watch for news and tips on activated sludge technology, and practical information on activated sludge plant design, troubleshooting, operations and training.

We also provide a range of easily affordable internet-based training courses for effective wastewater plant design and operations. To keep yourself informed on our latest resources and upcoming courses, sign-up for our free newsletter today!
