Phytoremediation of Wastewater Containing Lead and Manganese Ions Using Algae

Abstract

Heavy metal pollution of water from industrial discharge is a major problem worldwide. Thus, the quality of the environment and human health are severely affected. Various conventional technologies have been applied for water treatment, but these can be expensive, especially for industrial water treatment, and may have limited treatment efficiencies. Phytoremediation is a method that is successfully applied to remove metal ions from wastewater. In addition to the high efficiency of the depollution treatment, this method has the advantages of a low cost of the operation and the existence of many plants that can be used. This article presents the results of using algae (Sargassum fusiforme and Enteromorpha prolifera) to treat water containing manganese and lead ions. It was observed that maximum efficiencies for wastewater treatment were obtained when was used the algae Enteromorpha prolifera for a 600 min contact time period. The highest wastewater treatment efficiency obtained using Sargassum fusiforme was 99.46%.

Potential for Applying Nature-Based Solutions to Urban Waterways: The Case Study of Medveščak and Črnomerec Streams in the City of Zagreb, Croatia

“…Vegetation is an important element of aquatic ecosystems and NBSs. Phytoremediation (Phytostabilization, Phytofiltration/Rhizofiltration, Phytovolatilization, Phytoextraction, Phytotransformation, and Phytostimulation) represents great potential as a non-destructive, economically acceptable, efficient, environmentally friendly, and safe alternative to conventional cleaning techniques for the revitalisation of water and surrounding soils [70][71][72][73]. The basic components of the wastewater treatment system using aquatic plants are substrate, aquatic plants, microorganisms, algae, and wastewater.…”

Cellulose-Based Hydrogels for Wastewater Treatment: A Focus on Metal Ions Removal

“…Heavy metal ions, such those of lead, copper, arsenic, cadmium, and nickel, tend to accumulate in living organisms and, due to their toxicity, high permeability, and lack of degradability, lead to a series of physiological disorders, causing alterations in development, constituting a serious threat to human health [2][3][4][5][6]. In fact, evidence accumulated over the years links heavy metals to various diseases that afflict the human population, such as cancer, anemia, and hypertension, as well as damage to the nervous system and kidney failure.…”
