Direct potable reuse water management strategy as the most suitable potable water supply and wastewater disposal solution for the artificially constructed island in the Baltic sea

Abstract

The purpose of this Bachelor’s thesis was to make an attempt to theoretically prove that a closed-cycle water management strategy based on the concept of direct potable reuse (i.e., reapplication of highly-treated wastewater produced by a sequence of wastewater treatment and advanced water treatment for potable purposes) will be the most suitable water management solution for the artificial island planned to be constructed in the Baltic Sea. This is because the implementation of other water management strategies based on more traditional linear water management models or implementation of another closed-cycle water management model based on the concept of indirect potable reuse will be limited by the specific characteristics of the island, the aquatic environment surrounding the island, and the available water sources.

In order to provide a more meaningful rationale for the consideration and proposition of the concept of direct potable reuse as the most suitable water management solution for the planned island, the thesis contains a description of all other possible water management strategies based on the available water sources and delineating the probable impediments hampering their implementation in the project setting. Also, since there are two possible direct potable reuse scheme configurations, two available environmental water sources, and two possible application bases of these water sources, the thesis also considered all possible direct potable reuse water management strategies based on the aforementioned parameters and selecting the most suitable for the planned island from them all.
