Manuscript Submission Deadline 03 April 2023

Aquatic pollution poses a threat to the environment, aquatic habitats, and human health. There are many types of water pollution, such as sewage, and wastewater from industrial, agricultural, and aquaculture activities. It is therefore necessary to find appropriate and effective ways of removing toxic substances from aqueous solutions and industrial effluents. These organic and inorganic pollutants may include nutrients, personal care products and pharmaceuticals from domestic wastewater, heavy metals and textile dyes from industrial plants, nutrients and antibiotics from aquaculture effluents, and pesticides, ammonia, and other nitrogenous compounds from agricultural wastewater. Several approaches have been applied to remove these pollutants, such as ion exchange, filtration, adsorption, etc. However, most of these methods have disadvantages such as having high operation costs, low efficiency and being environmentally unfriendly.

Aquatic organisms are one of the most environmentally friendly, sustainable, and effective biomaterials which can reduce the harmful impact of various pollutants on ecosystems. Aquatic plants (macro- and micro-algae, and seaweeds), cyanobacteria, bacteria, fungi, and shellfish have a significant ability to treat a wide range of polluted waters. Phytoplankton can convert highly toxic pollutants into less biologically toxic chemicals. At the same time, they can utilize these wastes to produce several high-valuable compounds (amino acids, fatty acids, pigments, polysaccharides, etc.) as co-products.

This Research Topic aims to address current and novel biological wastewater treatment methods. We welcome submissions on the following themes:

1. Shellfish as biological filtration.
2. Sewage effluent as a source of microalgae nutrients used in wastewater treatment.
3. The use of seaweed in improving bioremediation capacity.
4. Potential applications of cyanobacteria in effluent wastewater treatments.
5. Macro- and micro-algae in various forms (e.g., wet or dried) as a low-cost adsorbent for the phytoremediation of toxic dyes, heavy metals, and other pollutants from aqueous solutions or real wastewaters.
6. Bacterial remediation, including microalgae/ bacteria or fungi/ bacteria consortia
7. Characterization of aqua-biological absorbents and their mechanisms of action in remediation.

Keywords: macroalgae, nurtrients, wastewater treatment, nature-based solutions, adsorption, filtration, fungi, Aquatic Plants, Microalgae, Cyanobacteria, Shellfish, Bioremediation, seaweed, aquaculture wastewater, effluent wastewater, water treatment


Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
