“…However, unsustainable aquaculture can give rise to new problems, such as water pollution, if the effluent and wastewater are not meticulously maintained. Water pollution caused by effluent from ponds is one of the main issues related to aquaculture [3,4]. Aquaculture has become large enough to have significant impacts on the environment, and some environmental concerns have been expressed by environmental activists and scientists [5].…”

The lack of clean water sources, due to the presence of pollutants in water, is a major issue in many countries, including Malaysia. To overcome this problem, various methods have been introduced, including phytoremediation treatment. Therefore, this phytoremediation study examined the ability of five aquatic plants—Centella asiatica, Ipomoea aquatica, Salvinia molesta, Eichhornia crassipes, and Pistia stratiotes—to remove three pollutants—total suspended solids (TSS), ammoniacal nitrogen (NH3-N), and phosphate—from aquaculture wastewater. Using wastewater samples, each containing 50 g of one of the plants, the pollutant levels were measured every two days for 14 days. The results showed a drastic decline in the concentration of pollutants, where C. asiatica was able to remove 98% of NH3-N, 90% of TSS, and 64% of phosphate, while I. aquatica showed the potential to eliminate up to 73% of TSS and NH3-N, and 50% of phosphate. E. crassipes drastically removed 98% of phosphate, 96% of TSS, and 74% of NH3-N, while P. stratiotes was able to eliminate 98% of TSS, 78% of NH3-N, and 89% of phosphate. S. molesta was efficient in removing 89.3% of TSS and 88.6% of phosphate, but only removed 63.9% of NH3-N.

“…Water treatment is essential in ensuring access to a clean water supply [65][66][67][68][69][70][71][72]. The present study evaluated the applicability of the EC method in the removal of salts (TDS, CL, Br and SO 4 2− ) from aqueous environments using aluminum electrodes.…”

Saline water treatment has become increasingly important for drinking water supplies. The aim of this study was to evaluate the ability of the electrocoagulation (EC) process with combined aluminum electrodes in removing various types of salt from water samples collected at Sawa Lake, Al-Muthanna, Iraq. The targeted types of salt include total dissolved solids (TDS), chloride salt (Cl−), bromine (Br−), and sulphate (SO42−). A bench scale consisting of combined EC configurations with static electrodes was employed under combined electrical connections. The effect of the six variables factors, such as applied current density (I), reaction time (RT), pH, temperature (T), stirring speed (Mrpm) and inter electrode distance (IED) were observed to achieve a higher removal of TDS, Cl−, Br− and SO42−. Initial results showed the following optimum operating conditions: I = 2 mA/cm2, RT = 80 min, pH = 8, T = 25 °C, IED = 1 cm and Mrpm = 500. The maximum removal efficiency of TDS, Cl−, Br− and SO42− were 91%, 93%, 92% and 90%, respectively. It can be concluded that the EC method applied in the present study was effective to removing salts from lake water.

“…Several methods for treating industrial wastewater include adsorption, precipitation [5,6], coagulation [7], ion exchange, cementation, electrodialysis, electrowinning, electrocoagulation, and reverse osmosis [2]. However, the coagulation-flocculation process has been chosen as the primary alternative because it has more advantages than other methods [8], such as the low cost of a simpler water treatment process and the ability to reduce the repulsion force between colloidal particles for the formation of flocs, which can easily settle to the bottom.…”

Archidendron jiringa seed peel extract was used to aid the coagulation-flocculation process to ultimately remove lead from synthetic residual water. The effectiveness of this method was studied to obtain an alternative approach that is easy to be handled with low cost and energy in removing the lead from residual water. Optimum parameters were analyzed to determine the effectiveness of lead removal, including pH, alum dose, and A. jiringa seed peel extract dose. A study on the coagulation-flocculation process with and without the aid of A. jiringa was also conducted. The optimum pH, the alum dose, and the A. jiringa seed peel extract dose were 9.0, 2.44 g/l, and 60.2 mg/l, respectively. The percentage of lead removal with the aid of A. jiringa seed peel extract was 79%, and the percentage was dropped to only 47% without the extract. A significantly higher rate in the coagulation-flocculation process due to the presence of A. jiringa seed peel extract proved its effectiveness in removing lead from wastewater.
