“…The concentration of phosphate in RAS water after treatment was lower than 0.08 mg P/L in every treatment cycle with an average of 0.03 mg P/L from all 12 treatment cycles, that is, 98.6 ± 0.8% phosphate was removed. With simple calculation, phosphate removal rate of this photobioreactor was 2.17 mg P/L/d which was faster and more effectively than a previous study using Synechococcus elongatus (Ruiz‐Güereca & Sánchez‐Saavedra ).…”

“…Due to the complexity of phosphate removal processes using phosphate accumulating organisms (PAOs) under a sequential anaerobic-aerobic processes (Ramasahayam et al 2014), phosphate removal is still a bottle neck for the development of long-term recirculating aquaculture systems. Therefore, several technologies have been proposed for phosphate removal such as using natural Jordanian zeolitic tuff as an adsorbent (Aljbour et al 2016) and photosynthetic microorganisms such as algae and cyanobacteria (Zhang et al 2008;Burut-Archanai et al 2013;Rai et al 2016;Ruiz-G€ uereca & S anchez-Saavedra 2016). Using microalgae for phosphate removal is less complicated than PAOs.…”

Unicellular cyanobacterium Synechocystis sp. was used for phosphate removal in a recirculating aquaculture system. The cell harvesting was performed using chitosan solution in this study. The parameters (i.e. cell density, pH of cell suspension and chitosan concentration) affecting the flocculation efficiency of chitosan were investigated. With the optimal condition, the repeated flocculation for phosphate removal in a photobioreactor was demonstrated. The results show that the flocculation efficiency of chitosan depends on cell density, pH of cell suspension and chitosan concentration. The optimal flocculation process could be accomplished by adjusting the pH to 7.2 before adding 20 mg/L chitosan followed by pH adjustment to 7.5. With single inoculation, the sequential process of phosphate removal using cyanobacterial uptake followed by cell flocculation using chitosan with the optimal condition in the photobioreactor was successfully achieved for 12 cycles with water from a recirculating fish tank.
