“…Plant-based coagulants need preparation process to be a ready product for the coagulation treatment method (Figure 5). The preparation process includes three steps : 1) griding (primary), 2) extraction (secondary), and purification (tertiary) (Okolo et al, 2021;Vardhan et al, 2019). The most important step in the primary stage is screening usable parts.…”

“…It is then necessary to proceed with its elimination and, failing that, its reduction to limit values before discharging any effluent containing it into the environment [12] [13]. Several methods of eliminating these metals are used, including precipitation, adsorption, ion exchange and membrane filtration [14] [15] [16] [17].…”

“…"There are various techniques used in removing turbidity, suspended solids, dissolved solids and colour from water and wastewaters such as chemical precipitation, biological treatment, membrane filtration, photocatalysis, ion exchange resin, coagulation/flocculation and adsorption" [11]. Adsorption was used in this work due to its low cost, simplicity and effectiveness.…”

“…The conventional effluent treatment chemicals like the multivalent salts of iron and aluminium as well as activated carbons are usually imported and cause post application challenges. For instance, intake of water containing residual aluminium sulphate has been linked to Alzheimer disease and the resulting sludge from the use of such chemicals is difficult to recycle [11]. Against this backdrop, it became necessary to search for alternative wastewater purification reagents that are cheap, locally available, and environmentally friendly.…”
