From: Performance of polychaete assisted sand filters under contrasting nutrient loads in an integrated multi-trophic aquaculture (IMTA) system

Figure 1

Average values (± SD) of suspended particulate matter (SPM), particulate organic matter (POM), total nitrogen (TN), dissolved inorganic nitrogen (DIN), total phosphorus (TP) and dissolved inorganic phosphorus (DIP) of the values determined over 15 consecutive weeks (n = 15) in each of the three sets of polychaete assisted sand filters (PASFs). Raw PASFs—received the raw effluent from the earthen pond stocked with Sparus aurata; Df PASFs—received the raw effluent after being screened by a drum filter; and Df + Alg PASFs—received effluent after being screened by a drum filter and a macroalgae biofilter stocked with Ulva rigida.
