“…Wastewater from intensive animal farming is usually treated in treatment lagoons or constructed wetlands. Incomplete removal of many veterinary pharmaceuticals and steroid hormones has also been reported (Carvalho et al 2013;Kolz et al 2005;Liu et al 2015;Shappell et al 2007). Additionally, animal manures are commonly land applied as fertilizers in crop fields.…”

Pharmaceuticals and personal care products (PPCPs) consist of a variety of compounds extensively used for the treatment of human and animal diseases and for health or cosmetic reasons. PPCPs are considered as emerging environmental contaminants due to their ubiquitous presence in the environment and high environmental risks. In wastewater treatment plants using conventional activated sludge processes, many PPCPs cannot be efficiently removed. Therefore, there is an increasing need for more effective and cost-efficiency ways of removing PPCPs while treating wastewater. Algae-based technologies have recently attracted growing attentions for their potential application in wastewater treatment and hazardous contaminant removal, which are advantages in reducing operation cost while generating valuable products and sequestrating greenhouse gases at the same time. This work reviews the up-to date researches to reveal potential toxic effects of PPCPs on algae and algae-bacteria consortia, identify mechanisms involved in PPCP removal, and assess the fate of PPCPs in algae-based treatment systems. Current researches suggest that algae and algae-bacteria consortia have great potentials in PPCP removal but more works are required before algae-based technologies can be implemented in large scales. Knowledge gaps are identified and further research focuses are proposed in this review.

“…Their treatment potential is highly regarded because they could remove suspended solids (SS), total nitrogen (TN) and nitrogen compounds, total phosphorus (TP), pathogens, heavy metals and pharmaceuticals with low energy input (IWA 2000;Carvalho et al 2013). The major benefits of these systems are their low operational and maintenance cost compared to conventional systems such as activated sludge.…”

In Hokkaido, northern Japan, there are 12 hybrid subsurface constructed wetlands (HSCWs) and most of them are treating high concentrated organic wastewater. One of these systems is an HSCW situated in Embetsu, northern Hokkaido and it has been in operation since November of 2006 to treat dairy milking parlor wastewater. The system is composed of two vertical flow beds and a horizontal flow bed. The inflow and the outflow's flow rates and pollutant concentrations and loads were extremely variable. Throughout its six years of operation, most of the pollutant removals were decently high. Removal efficiencies for COD, BOD 5 and SS were ranging in the 90%. Removal efficiencies for TN, NH 4 -N, and BOD 5 were improving because of the development of the soil ecosystem and the Phragmites australis community. However, the removal rates of TP were decreasing, presumably because of the declining adsorption ability. The accumulation of TP in the first and the second vertical beds had reached its plateau. Vertical beds had high removal efficiencies for TN, COD, BOD 5 and SS. These high removal rates of the first vertical bed may be caused from the efficient removal of solid material that is deposited as an organic layer of the first vertical bed. High NH 4 -N removal rates exerted by the second vertical bed may be due to the recycling of wastewater. In conclusion, the HSCW was working excellently for its six years of operation, and it could be concluded that it has not reached its life yet.

“…The biodegradable organic matter present in the effluent was very low, with BOD values below the detection limit. Along the sampling weeks, the initial wastewaters presented COD values of 190-280 mg/L, which are very low in comparison with other type of effluents usually treated in CWs such as urban wastewaters (524 mg/L) [18] or livestock wastewaters (1042 mg/L) [26]. Nitrites, nitrates, ammonium and phosphates values present in initial wastewaters varied, respectively, between 86 and 415 mg/L, 453 and 801 mg/L, 166 and 252 mg/L and 11 and 26 mg/L.…”

Abstract:This work aimed to evaluate the potential of constructed wetlands (CWs) for removal of antibiotics (enrofloxacin and oxytetracycline) and antibiotic resistant bacteria from saline aquaculture wastewaters. Removal of other contaminants (nutrients, organic matter and metals) and toxicity reduction and the influence of antibiotics with these processes were evaluated. Thus, nine CWs microcosms, divided into three treatments, were assembled and used to treat wastewater (doped or not with the selected antibiotics) between October and December of 2015. Each week treated wastewater was removed and new wastewater (doped or not) was introduced in CWs. Results showed >99% of each antibiotic was removed in CWs. After three weeks of adaptation, removal percentages >95% were also obtained for total bacteria and for antibiotic resistant bacteria. Nutrients, organic matter and metal removal percentages in CWs treated wastewater were identical in the absence and in the presence of each antibiotic. Toxicity in treated wastewaters was significantly lower than in initial wastewaters, independently of antibiotics presence. Results showed CWs have a high efficiency for removing enrofloxacin or oxytetracycline as well as antibiotic resistant bacteria from saline aquaculture wastewaters. CWs can also remove other contaminants independently of drug presence, making the aquaculture wastewater possible to be reutilized and/or recirculated.
