“…The disposal of landfill leachate can be a source of severe pollution, especially for soil, water, and groundwater contamination (El-Salam and Abu Zuid, 2015). Similarly, public health hazards may also be caused by the discharge of untreated landfill leachate, especially into water bodies (Akinbile et al, 2012;Al Hamadani et al, 2011;Aziz et al, 2011). In an attempt to prevent an occurrence of this scenario, related government regulatory agencies are becoming more stringent and restrictive in the enforcement of environmental rules and regulations concerning the monitoring of contaminants from leachate waste streams (Maizatun, 2011).…”

Uncontrolled landfill leachate generation portends danger to the environment and aquatic ecosystem, especially without prior treatment before discharge. The application of Al-based coagulants, such as polyaluminum chloride (PACl), has the potential of introducing Al residuals into water bodies. Therefore, an alternative natural coagulant was recommended to reduce the usage of Al-based coagulants. In this study, a coagulation-flocculation process using the combination of PACl as coagulant and Tamarindus indica seed (TiS) as coagulant aid was used in treating the landfill leachate from the Alor Pongsu Landfill Site in Malaysia. Some of the optimum operational conditions determined were the pH and dosage of the coagulant aid, and their effect was considered on parameters, such as suspended solids (SS), color, and COD, using standard jar test procedures. The combination of TiS flocculant reduced the dosage of PACl coagulant from 5,000 mg/L to 2,750 mg/L with removal efficiencies of 99.3%, 97.3%, and 67.4% for SS, color, and COD, respectively.

“…Even though the quantity of the leachate is lesser than other wastewaters, its contents are extremely hazardous (Al-Hamadani et al 2011). In fact, landfill leachate continues to be dangerous and poisonous over long periods, particularly for ammoniacal nitrogen that leads to stimulated algae growth, accelerated eutrophication, enhanced dissolved oxygen depletion and increased toxicity for living organism in water body (Aziz et al 2004;Karadag et al 2008).…”

This study was carried out to investigate the treatability of ion exchange resin (Indion MB 6 SR) for the removal of chromium (VI), aluminium (III), zinc (II), copper (II), iron (II), and phosphate (PO 4 ) 3-, chemical oxygen demand (COD), ammonia nitrogen (NH 3 -N) and colour from semi-aerobic stabilized leachate by batch test. A range of ion exchange resin dosage was tested towards the removal efficiency of leachate parameters. It was observed that equilibrium data were best represented by the Langmuir model for metal ions and Freundlich was ideally fit for COD, NH 3 -N and colour. Intra particle diffusion model, pseudo first-order and pseudo second-order isotherm models were found ideally fit with correlation of the experimental data. The findings revealed that the models could describe the ion exchange kinetic behaviour efficiently, which further suggests comprehensive outlook for the future research in this field.

“…Their application in wastewater treatment has increased on account of their widespread abundance in nature and biodegradability. These bio-flocculants are derived from Abelmoschus esculentus, Malva sylvestris, Plantago psyllium, Plantago ovata, Tamarindus indica, and Trigonella foenumgraecum, and have shown promising results with respect to the treatment of biological effluent, landfill leachate, dye-containing wastewater, textile wastewater, tannery effluent, and sewage effluent (Al-Hamadani et al 2011;Anastasakis et al 2009;Mishra et al 2002a;Mishra et al 2003;Bajpai 2005, 2006;Mishra et al 2002b;Mishra et al 2004). …”
