“…Recently, bio-augmentation of plants with particular and adapted microbes has been extensively studied in phytoremediation [38,53,88]. Plant growth-promoting rhizobacteria (PGPR) proved to increase biomass production, disease resistance, and reduce metal induced toxicity in bio-augmented plants [89].…”

Heavy-metal (HM) pollution is considered a leading source of environmental contamination. Heavy-metal pollution in ground water poses a serious threat to human health and the aquatic ecosystem. Conventional treatment technologies to remove the pollutants from wastewater are usually costly, time-consuming, environmentally destructive, and mostly inefficient. Phytoremediation is a cost-effective green emerging technology with long-lasting applicability. The selection of plant species is the most significant aspect for successful phytoremediation. Aquatic plants hold steep efficiency for the removal of organic and inorganic pollutants. Water hyacinth (Eichhornia crassipes), water lettuce (Pistia stratiotes) and Duck weed (Lemna minor) along with some other aquatic plants are prominent metal accumulator plants for the remediation of heavy-metal polluted water. The phytoremediation potential of the aquatic plant can be further enhanced by the application of innovative approaches in phytoremediation. A summarizing review regarding the use of aquatic plants in phytoremediation is gathered in order to present the broad applicability of phytoremediation.

“…At present, there are many methods used to treat eutrophication, which consist primarily of physical, chemical and biological methods [9][10][11]. Biological methods typically entail the use of aquatic plants to purify sewage, which has the advantages of simple operation and large economic and technical implementations.…”

Eutrophication is a phenomenon of excess nutrition that results from the natural or artificial enrichment of inorganic nutrients such that the system cannot regulate the circulation of nutrients [1]. Among 118 lakes in China, the proportion of mesotrophic lakes was 21.4% and that of eutrophication was 78.6% in 2016 [2]. It is clear that China faces serious water eutrophication, which will affect the ecological landscape and the safety of livestock drinking water [3]. Many factors lead to eutrophication and predominantly involve the addition of nitrogen and phosphorus [4]. In particular, nitrogen is an important cause of eutrophication [5], especially ammonium nitrogen and nitrate nitrogen contents. Large amounts of nitrate-enriched water pose a serious threat to human life and production. The World Health Organization [6] found that drinking high-nitrate water can endanger human health and safety [7]. As a result,

“…Thus, many traditional and innovative methods with physical, chemical and biological processes have been applied to alleviate eutrophication and improve water quality over the past decades [14,15]. Among those methods, eco-technologies (i.e., artificial floating islands) have been widely applied around the world due to low cost, easy maintenance, safe and high-efficiency [16,17]. An enhanced artificial floating island is a soilless planting structure that was constructed with the floating mats, aquatic plants, artificial biofilm carrier and related ecological communities (e.g., algae, biofilms, zooplankton and small invertebrates).…”

Water eutrophication is one of the most serious environmental problems in urban lakes and ponds due to the excessive nutrients. To deal with this problem, the development of methods for supporting ecological rehabilitation has been undertaken. Meanwhile, the trophic interactions during rehabilitation also have been analyzed. In this study, a new technique was employed to solve the water eutrophication problems in an urban pond. To evaluate the water eutrophication at a pilot scale, an enhanced artificial floating-type biological treatment system (FBTS) composed of a floating bed, macrophyte, artificial biofilm carrier (polyurethane sponge) and aerator could be used as equipment for urban pond remediation. In addition, FBTS was employed to decrease the total nitrogen (TN), ammonia-nitrogen (NH3-N), total phosphorus (TP) and chemical oxygen demand (COD) in water. Meanwhile, the changes of water qualities were monitored in the remediation process, and differences in phytoplankton functional group diversity were also registered. Cyanobacteria would decrease after the removal of P, and the diatom assemblage composition changed. The dominant species Cyanophyta were transformed to co-existed with Bacillariophyta, Pyrrophyta and Chlorophyta due to the improvement of water quality. Consequently, this new FBTS could be a promising eco-technology for the removal of nitrogen and phosphorus from eutrophic water, and even could promote the phytoplankton succession.
