“…Significant removal of COD achieved by okra coagulant compared to alum in dairy wastewater (Balamurugan & Shunmugapriya, 2019). Another study by Chonde & Raut, (2017) stated that M. oleifera seeds had similar coagulation properties to conventional coagulants such as alum which indicated that natural coagulants could be another approach to reducing the drawbacks of conventional coagulants towards the ecosystem. The COD removal efficiency of M.oleifera is high, which shows 75.6%, with minimal drawbacks to ecosystem compared to conventional coagulants (Fagundes-klen & Dotto, 2019).…”

Industrial effluent contains high concentrations of pollutants, such as heavy metals, which can cause risks to human health and the ecosystem. Chemical coagulants such as aluminum and iron salts are typically used as a coagulant in the wastewater treatment plant. The effectiveness of chemical coagulants is good in the clarification of wastewater, but excessive use is not sustainable and toxic. This study focuses on the removal of turbidity and chemical oxygen demand (COD) of various industrial effluents, including dairy wastewater, textile wastewater, paper, and paper mill industry, by comparing the removal between plant-based and chemical coagulants. The study aims to quantify the ability of plant-based coagulants to remove turbidity and COD in industrial effluents. A systematic review was used to conduct this study by using a systematic search strategy (PRISMA) in the relevant databases, which are Scopus, Web of Science, and Google Scholar. Only experimental studies that test both plant-based and chemical coagulants were chosen to proceed with metaanalysis to validate the efficiency of the plant-based coagulant to remove turbidity and COD in different industrial effluents by using Cochrane RevMan 5.4 software. Twenty-five articles were evaluated, and high heterogeneity was found among those studies. The mean difference (MD) and 95% confidence interval (CI) showed a significantly increasing percentage of turbidity and COD removal by plant-based coagulant by -1.64 % (-3.49, 0.21) and -5.39% (-8.85, -1.93) respectively for all wastewaters. The result supports the application of plant-based coagulant to sustain wastewater treatment due to its eco-friendly, non-toxic, biodegradable, and capability to sustain the pH of water after treatment.

“…M. oleifera is a medium size multipurpose tree found in northwest India and native to various parts of Asia, South America and Africa [3]. Pods of M. oleifera are non-hazardous and can be utilized as an economical and effective sorbent for the elimination of organics [4]. Application of alum and lime is a conventional coagulant used for water treatment worldwide.…”

“…To achieve this sustainable development, it is necessary to put into service the plant-based natural coagulant [3,8]. It is an eco-friendly and cheaper method for purification of industrial wastewater as compared to common coagulants like alum [2][3][4]9]. Table 2 shows the comparison between chemical (common) coagulant and natural coagulants.…”

“…To eliminate colloidal particles from wastewater numerous conventional methods were used, such as coagulation, flocculation, flotation, solvent extraction, adsorption, ion exchange, membrane filtration, precipitation, and biological methods [10]. The coagulation/flocculation process draws attention for the elimination of dissolved, colloids, suspended and organic matter present in industrial effluent [4,6,10,11]. Extraction of M. oleifera was more efficient than FeCl 3 to degrade the Clostridium perfringens spores extensively [7,12].…”

The present study deals with the appropriateness of the coagulation process using natural coagulant Moringa oleifera seed. Natural coagulants are useful for the treatment of wastewater because of its sustainability, cost-effectiveness, non-toxicity and lesser quantity of sludge formation. M. oleifera seed having a chemical composition of polypeptides having 6 amino acids like arginine acid, methionine acid, glutamic acid, phenylalanine, threonine, and histidine. M. oleifera is also known as a cationic polyelectrolyte and having molecular weight 6,000 to16,000 Dalton. The main objective of research work is the application of the M. oleifera seed as a natural adsorbent to treat synthetic dairy wastewater. The effects of pH, agitation time, the dose of sorbent and efficacy of M. oleifera seeds kernel for turbidity removal was assessed. M. oleifera seed eliminates turbidity 95 % and colour 94 % using 0.22 gm pod powder, and 0.2 L of 1.0 g/L synthetic dairy wastewater. Naturally dried M. oleifera seeds remove turbidity 95 %, sundried seeds remove turbidity 52 % and oven-dried seeds 45 %. As naturally dried M. oleifera pod having more surface area for adsorption and inter-particulate bridging which extract the extra active ingredients. pH range between 5 and 8 is more suitable to degrade the turbidity and colour. It is concluded that in the presence of an aqueous soluble cationic coagulant protein has great potential to remove the turbidity and colour of wastewater. HIGHLIGHTS oleifera seed having a chemical composition of polypeptides having 6 amino acids like arginine acid, methionine acid, glutamic acid, phenylalanine, threonine, and histidine oleifera seeds consist of crude fiber, lignin, hemicellulose, and cellulose. It also contains amino functional groups (R-NH3), carboxyl group (C=O), and fiber carbonaceous. The functional group present in M. oleifera seeds is dissociated during the adsorption process at various pH oleifera has good property of coagulation-flocculation (C-F) The effectiveness of naturally dried seed kernel is more effective than other seed kernels GRAPHICAL ABSTRACT
