Water quality in aquaculture farms is highly related to the quality of aquaculture products and the connected environment. Cadmium (Cd 2+ ) and polycyclic aromatic hydrocarbons (PAHs) are two of the most common pollutants in the aquaculture water, while biochar derived from waste algae ( Enteromorpha prolifera ), namely BE, was applied in farms ponds to improve water quality. Firstly, the adverse environmental impact of BE was minor, while the concentrations of the heavy metal (Cd 2+  in the present study) and PAHs (FLU, PHE, FLT and PYR) were removed with efficiencies of 49%, 88%, 90%, 91% and 88%, respectively. The ecological risk values (RQs) were reduced subsequently with a rate of 58 ± 11%. After dosing BE, the ecological risk values in all the studied ponds were lower than 1, indicating no ecological risk in the corresponding aquaculture environment. The sorption capacities ( q m) of BE were 15, 12, 6.3, 0.41, 0.29 and 0.56 mg·g −1  for Cd 2+ , FLU, PHE, FLT, PYR and BaP, respectively. The sorption capacities were acceptable compared with those derived from other types of biomass. The removal mechanisms were partition (PAHs), complexation (Cd 2+ ), π-π interaction (Cd 2+  and PAHs), precipitation (Cd 2+ ) and ion-exchange (Cd 2+ ). Practically and theoretically, the algae biochar is applicable in the aquaculture environment, where Cd 2+  and PAHs co-exist.
