Thesis topic:

Chemical and biochemical transformations of phosphorus in wastewater treatment

Motivation

Since there is a bigger and bigger scarcity of natural phosphate sources, which are used not only in agriculture as fertilizer, there is a need to find alternative sources. Huge potential for phosphorus (and its compounds) recovery should be in wastewater or sewage sludge, which are formed during wastewater treatment. There is a considerable amount of phosphorus (organic and inorganic) released into wastewater annually that should be removed before discharge into water bodies. This way the environment and valuable sources of drinking water are protected. Phosphorus is captured in sewage sludge that is further processed (hygienization, stabilization,...). Hereafter, the sewage sludge is incinerated or disposed of in landfills thus phosphorus is irretrievably lost.

Solution

Within this topic, the knowledge of the chemical and biological transformation of phosphorus during wastewater treatment will be deepened. The thesis will be focusing on different possibilities of sewage sludge pretreatment (drying, pyrolysis, incineration,...) to improve phosphorus recovery. Three different types of sewage sludge will be investigated: biological (activated sludge), bio-chemical (activated sludge with simultaneous precipitation of phosphorus), and chemical (from tertiary stage phosphorus removal). Furthermore, there will be an effort to recover phosphorus from wastewater treatment plant effluent through the concentration of phosphorus in it thanks to membrane technology with the following precipitation. Part of the thesis concerns the assessment of compounds (formed during phosphorus recovery) for agricultural utilization.
