Article Polyhydroxyalkanoate production on waste water treatment plants: Process scheme

This work describes the production of polyhydroxyalkanoates (PHA) as a side stream process on a municipal waste water treatment plant (WWTP) and a subsequent analysis of the production potential in Germany and the European Union (EU). Therefore, tests with different types of sludge from a WWTP were investigated regarding their volatile fatty acids (VFA) production-potential. Afterwards, primary...

Retrofit of Water Networks in Process Plants

In this paper, we present a methodology for the retrofit of water utilization systems using mathematical optimization. The problem consists of determining the best re-piping and the capacity of a new treatment unit (if any) to be introduced to generate the best retrofit. Instead of reducing water consumption, or maximizing savings, we resort to analyze the problem using a more comprehensive vie...

Virtual commissioning of process automation software in drinking water treatment plants

In industry, the traditional factory acceptance test (FAT) of process automation (PA) software is being replaced by virtual commissioning (VC). In this paper VC is introduced in drinking water treatment. A quantitative measure has been defined to compare the shortenings of time-to-market of projects tested with VC and FAT, while taking into account the size and complexity of the software. The m...

A comparative study of prediction models for Coagulation process in drinking Water Treatment Plants

Coagulation process is an essential part of drinking water treatment operations. The jar test is a widely-used laboratory procedure to determine the quantity of coagulation chemical dosages for water treatment plants. However, the test is not effective for real-time control of this process due to the nonlinear behaviour and rapid variations of water quality parameters. In this study, empirical ...
