Design of Modern Wastewater Treatment Plants


EWA Innovation Workshop will take place at UCT Prague in April 2019

A new type of EWA (European Water Association) workshops will be organized with different topics and in different EWA member countries. The workshops will be usually held back-to-back with other EWA activities like the Executive Directors meeting in this case.

The April 2019 workshop at UCT Prague will be devoted to modern wastewater treatment plants. That’s also why EWA chose Prague as the venue of the workshop because the City of Prague started in September 2018 a trial operation of new “water line” of the Central Wastewater Treatment Plant. This new line is exploiting several processes and operations which are still not common in large wastewater treatment plants, e.g., chemically enhanced primary treatment, cascade D-N activated sludge process with in-situ bioaugmentation of nitrification bacteria or tertiary phosphorus precipitation. The design and construction of the plant had to deal with the requirement of the city to protect the new plant from floods comparable to the historical disastrous flood in 2002. This new facility will help the city to meet the effluent limits according to the 91/271/EEC directive on one side and on the other side it will enable the reconstruction and upgrade of the existing Central Wastewater Treatment Plant built in the 1960s.

Besides listening to the lectures on the Prague project and on newest trends and challenges in wastewater treatment plant design the workshop participants will have the chance to see the technology of the New Water Line completely hidden in a concrete containment.
