Special Issue Information

Dear Colleagues,

Wastewater treatment technology has a history spanning thousands of years, while the activated sludge process is only 100 years old. Wastewater treatment technology has been developed by combining basic science such as chemistry, microbiology, and biochemistry with various engineering technologies such as civil engineering, chemical engineering, and biotechnology.

To solve global problems such as water shortages and energy crises, wastewater is recognized as a resource, and various wastewater treatment technologies are being researched.

Thus, this Special Issue aims to collect and present breakthrough research on all wastewater treatment technologies, including activated sludge, anaerobic digestion, membrane bioreactors, membrane aerated biofilm reactors, microbial electrochemical technology and other removal mechanisms, and microbial communities. The scope of this Special Issue covers, but is not limited to, the following topics:

  • Conventional and advanced wastewater treatment technologies (including AS, AD, MBR, and others);
  • Energy-neutral or low-energy wastewater treatment technologies (MABR, ANAMMOX, and others);
  • Nitrogen or phosphorus removal technologies;
  • Removal mechanisms and microbial communities in wastewater treatment processes.

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. Applied Sciences 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 2400 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.

In this study, we aimed to develop a mathematical description of the process of phosphate sorption on Rockfos® material using the Langmuir isotherm and determine the basic parameters for modeling this process. The Rockfos® material was formed through the thermal treatment of opoka at 980 °C and is highly reactive due to its significant calcium and silicon compound content. This study included an evaluation of the phosphate retention efficiency on the material as a function of the phosphate concentration in the initial solution (0.5 mg/L, 1.0 mg/L, and 2.0 mg/L), sorbent grain size (1.0–1.6 mm, 1.6–2.5 mm, and 2.0–5.0 mm), and process temperature (5 °C, 10 °C, 15 °C, 20 °C, and 25 °C). It was found that an increase in the process temperature and the phosphate concentration in the solution favored sorption, while the effect of the sorbent grain size was ambiguous. It was determined that sorption can be described well using the Langmuir linearization of the Langmuir model. Thermodynamic analysis and the separation coefficient suggest that phosphorus sorption on Rockfos® material is primarily based on chemisorption, and the process is endothermic and spontaneous over the entire temperature range. The determined parameters of the tested material, especially the qmax (maximum sorption capacity), provide a basis for the design of a filter for removing phosphate from wastewater, assuming that the load is equal to the inflow to the filter and adheres to the specified requirements for treated wastewater.
