“…Coagulation-flocculation processes using starch as a natural coagulant have been investigated by various workers, such as rice starch in palm oil mill effluent treatment, corn starch in dye wastewater treatment, tapioca starch in semiconductor wastewater treatment, and sago starch in synthetic wastewater (Teh et al 2014;Louis and Sudha 2013;Fatehah et al 2013 andAziz et al 2000). Common advantages of natural coagulants are cost-effectivity, biodegradability, and non-toxicity (Hasbi 2013).…”

Malaysia is one of the highest starch producers. In this study, sago starch was utilized as a natural coagulant aid to reduce the dosage of aluminum-based coagulant in leachate treatment. The potential of native sago trunk starch (NSTS) and commercial sago starch (CSS) was evaluated as sole coagulant and coagulant aid in the presence of polyaluminum chloride (PACl) in the removal of color, suspended solids (SS), NH3-N, turbidity, chemical oxygen demand, organic UV254, Cd, and Ni. Leachate was sampled from Pulau Burung Landfill Site, one of the semi-aerobic landfills in Malaysia. The optimum dosage for PACl in the presence of NSTS or CSS as coagulant aid was reduced from 3100 to 2000 mg/L. In the presence of 2000 mg/L PACl with 6000 mg/L NSTS and 2000 mg/L PACl with 5000 mg/L CSS, the removal performance for color, SS, and turbidity are 94.7, 99.2, and 98.9%, respectively. Similar results were obtained with the use of 3100 mg/L PACl alone. Therefore, CSS and NSTS can be used as coagulant aid.

“…The powder was stored in a tight container and kept in room temperature for further use. Next, to prepare the TPP coagulant solution, a range of the amount of TPP in grams of was weighed and diluted into 100 ml of distilled water [49,50], producing the respective concentrations of TPP solution. The solution was stirred on the hot plate of 70-75 ℃ to promote the starch gelatinisation.…”

A combination of a metal coagulant with an organic polymer can complement both the outstanding and flaw properties of the separate elements. A novel composite coagulant of polyaluminium chloride (PAC)-tapioca peel extract powder (TPP) called PACTPP with different weights ratio was prepared in this study. In the preliminary study, PACTPPg at the weight/weight ratio of TPP/Al=3.71 was selected as the optimum one based on the performance in treating wastewater sample of landfill leachate. Through all characterisation analyses, it revealed that the novel composite reagent exhibits better coagulant properties when compared with the individual coagulants of PAC and TPP. It was characterised that PACTPPg had combined the best benefits from PAC and TPP, with an acidic property of pH 3.45, the low charge density of 3.45 mV, the higher molecular weight of 1.59 × 107 g/mol, the bigger particle size of 4.528 × 104 d.mn, and a longer connected and compact structure. Through Fourier transform infrared (FTIR) and X-ray diffraction (XRD) analyses, PACTPPg was identified to comprise new chemical compounds, i.e., the functional groups of ketones, aldehydes, and alkanes in a semi-formed crystalline phase. Based on the comparison study, it can be concluded that PACTPPg showed a correlation to encompass the complex interpenetration networks rather than just a simple mechanical mixing of raw materials.

“…The renewable sources of them also mean the continuous supply of raw materials in development of coagulants. Therefore, the cheaper cost of coagulating agents could be obtained in future in attempt to Fatehah et al (2013) replace the hazards of using inorganic metal salts (Altaher et al 2016;Yin 2010). Fundamentally, the utilization of plant-based coagulants during early years also initiates further researches regarding the potential natural materials to be developed as coagulants (Awang & Aziz 2012;Birima et al 2013;Subramonian et al 2014).…”

The introduction of natural materials into the coagulation-flocculation process need to be practiced as common as possible. The previous literature indicated that utilization of natural material is actually worth to be developed and if possible, into the commercial one. However, the application of natural coagulants itself as the primary treatment is not sufficient, due to the rise in constraints which limited its performance. Emerging technologies and depth studies are actually helping these limited conditions to grow them as good as the performance of chemical coagulants. Alternatively, the natural-based coagulants are commonly used as coagulant aids alongside chemical coagulants, which have created a highlight in water research. This review covers the type of coagulants used in the coagulation-flocculation of wastewater treatment especially in the usage of natural-based coagulants. This review paper also outlines the future prospects of natural materials as aids and its potential as sustainable composite coagulants.
