Introduction
I have a background in environmental technology and microbiology and a PhD from Mälardalen University, Sweden. My research concentration has mostly been in wastewater microbiology and during my PhD program, I worked with wastewater treating photobioreactors. My bachelor's and master's degree work was done in the University of Tartu.

Thesis
Full-text available
Microalgae reactors, commonly known as photobioreactors, have become increasingly popular as an alternative for wastewater treatment. These systems reduce pollutants and remove nutrients such as nitrogen and phosphorous compounds from wastewater utilizing microalgae and bacteria. The biomass produced in the reactors can potentially be used to produ...
Article
The effect of inhibiting nitrification on algal growth and nutrient uptake was studied in photobioreactors treating municipal wastewater. As previous studies have indicated that algae prefer certain nitrogen species to others, and because nitrifying bacteria are inhibited by microalgae, it is important to shed more light on these interactions. In t...
Article
Full-text available
Because microalgae are known for quick biomass growth and nutrient uptake, there has been much interest in their use in research on wastewater treatment methods. While many studies have concentrated on the algal treatment of wastewaters with low to medium ammonium concentrations, there are several liquid waste streams with high ammonium concentrati...
Article
Full-text available
Photobioreactors are a novel environmental technology that can produce biofuels with the simultaneous removal of nutrients and pollutants from wastewaters. The aim of this study was to evaluate the effect of lake water inoculation on the production of algal biomass and phylogenetic and functional structure of the algal and bacterial communities in...
Article
Microalgae grown in photo-bioreactors can be a valuable source of biomass, especially when combined with wastewater treatment. While most published research has studied pure cultures, the consortia of algae and bacteria from wastewater have more complex community dynamics which affect both the biomass production and pollutant removal. In this paper...

The objectives of this study were to determine the biofilm microbial activity and bacterial community structure and successions in greywater treatment filters and to relate the treatment efficiency to the bacterial community parameters. This 10-month study was performed in a newly established experimental system for domestic greywater treatment tha...
Article
Wastewater treatment systems receiving municipal wastewater are major dissemination nodes of antibiotic resistance genes (ARGs) between anthropogenic and natural environments. This study examined the fate of antibiotic resistome and class 1-3 integron-integrase genes in photobioreactors that were treating municipal wastewater diluted (70/30) with l...
Conference Paper
Full-text available
The microalgae-based activated sludge (MAAS) process was evaluated regarding the removal efficiency of organic matter and nitrogen from physiochemically pretreated municipal wastewater at different hydraulic retention time (HRT) on pilot scale. Additionally, the interplay between the algal and bacterial consortium was evaluated regarding the abilit...
Article
Full-text available
This work presents a simple model to describe the consortia of algae-bacteria in a photo-bioreactor. The model is inspired by the Activated Sludge Model (ASM) structure, which includes different process rates and stoichiometric parameters. The model comprises two main biomass populations (algae and bacteria), two dissolved substrates (ammonium and...
Conference Paper
Full-text available
Since microalgae are known for high biomass growth and high nutrient uptake they present an interesting option to treat wastewater while growing biomass for energy production. While there are many papers concentrate on the algal treatment of wastewaters with low to medium ammonium concentrations, there are many types of wastes with high ammonium co...
Conference Paper
In the present paper we have studied algae production and its potential for biogas production using landfill leachate as a substrate. This includes the algae interaction with the leachate and its potential effect on the algae sludge that is formed after biogas production. As a part of this, sorption capacity of microalgae in 9 different mixtures of...
Conference Paper
Full-text available
Sorption capacity of microalgae in 10 different mixtures of wastewater and lake water was evaluated for their ability to reduce heavy metal concentrations in wastewater. Cu, Zn and Ba concentrations were mostly reduced whereas Al and As concentrations actually increased in some samples. Co and Ni concentrations were more reduced in samples with pur...

Project
The aim of the project is to optimize the energy recovery from the microalgae based activated sludge (MAAS) process with bacteria/algae community for municipal waste water treatment followed by co-digestion of the produced microalgae and sewage sludge to provide an overall energy efficient water and sludge treatment system. see more on (http://www.mdh.se/forskning/inriktningar/framtidens-energi/maasica-mikroalgbaserad-aktivslamprocess-integrerad-med-samrotning-av-alger-och-slam-1.90527)
