“…For example, the overdosing of alum in water or in wastewater treatment may lead to a high residual aluminum concentration. The prolonged exposure to water with high residual aluminum content is linked to serious health issues, such as the development of Alzheimer's disease and senile dementia (Bodlund et al, 2014;Shak and Wu, 2014;Singh and Kumar, 2011;Rondeau et al, 2001). Hence, many natural coagulants/flocculants have been used for the treatment of textile wastewater (de Souza et al, 2014;Fatombi et al, 2013;2005 Natural polymers are more advantageous than inorganic compounds because they produce denser and more compact flakes, reduce the required inorganic coagulant dosage and produce smaller quantities of sludge (Renault et al, 2009).…”

“…LBG is a polysaccharide galactomannan, which is a non-ionic polymer without dissociable ionic groups. This condition suggests the destabilisation of colloidal particles through polymer bridging, which is governed by hydrogen bonding (Singh and Kumar, 2011; Teh et al, 2014). The bridging mechanism that occurred via the adsorption of polymers on the surface particles may be due to the chemical interactions between the flocculant molecules and destabilised particles, thereby linking the particles together to form aggregates.…”

“…A series of loops and tails was developed when the LBG polymer chain interacted with colloidal particles. The polymer acted as a bridge in the formed particle–polymer–particle aggregates when a second particle with few empty binding sites contacted with the extended tails and loops in the solution beyond the surface and attached with other particles (Sharma et al, 2006; Singh and Kumar, 2011). Thus, the high reduction efficiencies of BPA and 2,4-Di-tert-butylphenol using LBG could be due to effective polymer adsorption and bridging.…”

Removal of bisphenol A and 2,4-Di-tert-butylphenol from landfill leachate using plant- based coagulant

Landfill leachate contain persistent organic pollutants (POPs), namely, bisphenol A (BPA) and 2,4-Di-tert-butylphenol, which exceed the permissible limits. Thus, such landfill leachate must be treated before it is released into natural water courses. This article reports on investigations about the removal efficiency of POPs such as BPA and 2,4-Di-tert-butylphenol from leachate using locust bean gum (LBG) in comparison with alum. The vital experimental variables (pH, coagulant dosage and stirring speed) were optimised by applying response surface methodology equipped with the Box-Behnken design to reduce the POPs from leachate. An empirical quadratic polynomial model could accurately model the surface response with R values of 0.928 and 0.954 to reduce BPA and 2,4-Di-tert-butylphenol, respectively. Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM) were performed on treated flocs for further understanding. FTIR analysis revealed that the bridging of pollutant particles could be due to the explicit adsorption and bridging via hydrogen bonding of a coagulation mechanism. SEM micrographs indicated that the flocs produced by LBG have a rough cloudy surface and numerous micro-pores compared with alum, which enabled the capture and removal of POPs from leachate. Results showed that the reduction efficiencies for BPA and 2,4-Di-tert-butylphenol at pH 7.5 were 76% and 84% at LBG dosage of 500 mg·L and 400 mg·L, respectively. Coagulant dosage and pH variation have a significant effect on POPs reduction in leachate. Coagulation/flocculation using LBG could be applied for POPs reduction in leachate as a pre-treatment prior to advanced treatments.

In addition, the prolonged exposure to water with high residual aluminum contents linked to serious health issues, such as the development of Alzheimer's disease and senile dementia [3][4][5][6]. There are also coagulants derived from plant-based materials known as natural coagulant.…”

Natural coagulants have proven its coagulation efficacy as reported in a significant number of research articles. However, the acceptance and massive application of natural coagulants in the water industry is still low. It is important to conduct a review to raise the potential of using natural coagulants by highlighting the efforts and the current development for refining the capability of natural coagulants, including showing the compatibility of natural coagulants with other treatment technologies in hybrid/integrated treatment procedures; the modification of natural coagulants for the possibility of hybridizing natural coagulants with additional kinds of coagulants; marked enhancement in coagulation performance efficiency; the improvement of extraction and purification methods for high purity of natural coagulants and the synthesis of multifunctional natural coagulants. However, the present progress of natural coagulants is quite encouraging, perspectives from sustainability assessment showed that the acceptance and commercialization of natural coagulants are stuck by two main challenges: feasibility and practicality of real field application and sustainability of using natural coagulants commanding technical, economic, environmental, and social aspects. Upcoming research focusing on these subjects may assist in clarifying the uncertainties shrouded on natural coagulants and at the same time modifying the water industry to be more sustainable.
