Special Issue Information
Dear Colleagues,
The use of microalgae for wastewater treatment, also known as phycoremediation, has received growing interest in recent years, due to the potential low cost of the process and to the wide possibilities of resource recovery from microalgae from a circular economy perspective.
However, microalgae-based treatments are strongly dependent on the local climate and their overall performance depends on the activity of both microalgae and bacteria, always present in wastewater and in open systems. Another important point, which is increasingly emerging, is that on a full scale it is impossible to select the algal strain, and the properties of the produced biomass are strongly affected by the environmental and operating conditions, as well as by the chemical composition of the influent. Further, the composition of the microalgal population shows seasonal changes.
Among the different research topics, the Special Issue will include:
- Evaluation of the specific contribution of microalgae and bacteria in wastewater treatment
- Long-term experiences at full and pilot scale: removal efficiency of nutrients, metals and emerging and priority pollutants, disinfection.
- Knowledge and management of limiting factors
- Causes of sudden failures in microalgae cultures, including parasites and other biological interactions
- Valorisation of the microalgal biomass (anaerobic digestion, bioethanol and biodiesel, biofertilizers, feed for animals and aquaculture, extraction of selected compounds).
Manuscripts should provide insights into feasibility, including economic and technical aspects for full-scale implementation.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
