“…Different from the results encountered in the present study, Fia et al (2017) observed no significant difference in TP removal in cultivated and uncultured CWs. Mendonça et al (2012) also obtained no significant difference between cultivated and uncultivated HSSF-CWs for the removal of phosphorus, finding mean removal efficiencies of 33.6% (HSSF-CW filled with gravel and cultivated with cattail), 28.8% (HSSF-CW filled with gravel and cultivated with marsh lily), 34.3% (HSSF-CW filled with a mixture of sand + gravel and cultured with cattail), 34.2% (HSSF-CW filled with a mixture of sand + gravel and cultivated with marsh lily) and 18.6% (HSSF-CW filled with a mixture of sand + gravel and without vegetation).…”

“…Table 3 shows that there was no difference in K removal between cultivated and uncultured HSSF-CWs. Fia et al (2017) evaluated the influence of vegetation on HSSF-CWs for the removal of pollutants from swine wastewater (SWW). The authors found no significant difference in potassium removal efficiency, with values of 27% in the three HSSF-CWs evaluated (uncultivated, cultivated with cattail and cultivated with Tifton 85 grass).…”

The present work evaluated the influence of filling substrate material (crushed PET bottles or fine gravel) on the efficiency of pollutant removal in horizontal subsurface flow constructed wetlands (HSSF-CWs). They were cultivated with a consortium of elephant grass cv. Napier (Pennisetum purpureum Schum) and Tifton 85 (Cynodon spp.) to treat wastewater from a common milk cooling tank (WWMT). For this, six HSSF-CWs were used which had dimensions of 0.6 m tall x 1.0 m wide x 2.5 m long. In order to investigate possible efficiency loss in the removal of pollutants from the system, operation was divided into two periods: Period I (from April to December 2015) and Period II (April to December 2016). Thus, the removal efficiencies of BOD5, solids and total nitrogen (TN), total phosphorus (TP), potassium (K) and sodium (Na) from WWMT were statistically compared. Results indicated that the efficiency of the HSSF-CWs for removing pollutants increased or remained similar after one year and nine months of their operation; and PET bottles were a viable alternative substrate in HSSF-CWs based on the efficient removal of pollutants from WWMT during the one year and nine months of monitoring. Crushed PET bottles constitute a viable substrate for filling HSSF-CWs. Altering the cultivation positions of the plant species did not change pollutant removal efficiencies, but indicates the importance of species arrangement to maximize system performance.

“…On the other hand, vertical flow constructed wetland (VFCW) systems provide good conditions for nitrification, but denitrification does not occur in these systems. Thus, hybrid or combined systems, in which the advantages of each system type are combined, have been studied, allowing producing waste water with a reduced organic load and lower nitrogen concentrations (Mendonça et al, 2015;Fia et al, 2017).…”

This study aimed to assess the performance of a combined vertical flow (VFCW) and horizontal subsurface-flow (HFCW) constructed wetland systems built on a pilot scale and submitted to different configurations and organic load application rates of pre-treated swine wastewater (SWW) in anaerobic systems on the nitrogen and phosphorus removal.The average values of redox potential in the systems were between anoxic and aerobic conditions, favoring an increased nitrate concentration in VFCW. Nitrogen removal by VFCW-HFCW system can be considered as satisfactory, reaching removal values of 75%. VFCW and HFCW proved to be limited in phosphorus removal, reaching values of 48%.

Adaptation of domestic effluent for agricultural reuse by biological, physical treatment and disinfection by ultraviolet radiation

Domestic effluent reuse is an alternative for irrigated agriculture in situations of reduced water availability. However, as there is the presence of pathogens in wastewater, the disinfection process is necessary before use. This research evaluated the sanitary and agricultural viability of treated wastewater at a pilot-scale station composed of a septic tank, Wetlands and an ultraviolet radiation (UV) disinfection system. The Sewage Treatment Station (STS) is installed in the Agricultural Sciences Center, UFSCar, in Araras city, SP, and receives 2000 L of sewage daily, which was monitored in terms of pH, turbidity, electrical conductivity (EC), dissolved oxygen (DO), sodium (Na), potassium (K), calcium (Ca), total nitrogen (TN), total phosphorus (TP), magnesium (Mg), total organic carbon (TOC), total coliforms (TC), Escherichia coli (E. coli) and Sodium Adsorption Ratio (SAR).The removal efficiency of the parameters was calculated based on the input and output means of each treatment unit. Results indicated removal efficiency for K (68.2%), TN (54.1%) and TP (36.1%). The levels of Na (26.7%) and Ca (22.9%) demonstrated the contribution of these salts to the wastewater; however, SAR did not present any risks for soil sodification. Microbiologically, the STS presented removal efficiency of 4 and 5 log-cycles for TC and E. coli, respectively. Therefore, results of monitoring indicate that the treated wastewater presents sanitary and agricultural viability, and conforms with the current legislation.
