Treatment of dairy manure effluent using freshwater algae: Algal productivity and recovery of manure nutrients using pilot-scale algal turf scrubbers

Advanced nutrient removal from surface water by a consortium of attached microalgae and bacteria: A review

“…Liu et al (2016c) installed microalgae-bacteria consortium under a planted floating treatment bed to improve the in-situ remediation efficiency of deep and static river water. Overall, the large number of existing photobioreactor configurations facilitate the application of attached microalgae-bacteria consortium for the treatment of polluted surface waters (Mulbry et al, 2008;Renuka et al, 2015). Additionally, the simultaneous action of the diverse nutrient removal pathways present in attached microalgae-bacteria consortium support the reduction of nitrogen and phosphorus in surface water as well as other kinds of wastewater to low levels (e.g., less than 2 and 0.1 mg L À1 for TN and TP, respectively, Table 4).…”

“…Natural colonization occurs spontaneously whenever a solid substrate is under proper climate and nutrient conditions in surface water (Mulbry et al, 2008;Liu et al, 2016b;Su et al, 2016). Although species-rich consortia are easily obtained via natural colonization, this is a slow process, which may bring about many undesired species with a negative influence on nutrient removal.…”

An overview of the utilisation of microalgae biomass derived from nutrient recycling of wet market wastewater and slaughterhouse wastewater

“…Rasala and Mayfield (2015) reported that phosphorus uptake by microalgae from wastewater is stored in cells in the form of polyphosphate. Mulbry et al (2008) revealed that microalgae have a high efficiency in removing phosphorus from wastewater as much as 70 to 90%. Microalgae take up inorganic phosphate from wastewater via luxury uptake in which algae cells absorb much more phosphate from water than what is necessary for growth (Solovchenko et al 2016).…”

Influence of light and temperature on the development and denitrification potential of periphytic biofilms

“…In recent years, there is growing research interests in utilizing natural periphytic biofilms in wastewater treatment, nonpoint source pollution control, and remediation of polluted waters (Furey et al, 2016;Wu et al, 2014). Biotechnologies such as algae turf scrubber (ATS), rotating algal biofilm reactor (RABR), and spiral periphyton bioreactor (SPB) have been developed based on periphytic biofilms for the treatment of a variety of contaminants and have showed promising results (Christenson and Sims, 2012;Mulbry et al, 2008;Shangguan et al, 2015;Lu et al, 2016).…”
