    In this study, natural polymers in the forms of starch from sago and tapioca were used as coagulant. The removal of turbidity and chemical oxygen demand (COD) using coagulation process from river water was examined. The treatment on the river water sample was evaluated via a series of Jar Test experimental works with rapid mixing speed of 120 rpm for 1 minute, slow mixing speed of 30 rpm for 20 minutes and settling time of 60 minutes. The tapioca starch removed 93.7% of turbidity at dosage of 1000 mg/L. While, sago starch successfully removed 96.4% of turbidity under optimum dosage of 2000 mg/L. pH 12 was optimum pH for turbidity removal by using sago and tapioca starch whereas the highest percentage of COD removal occurred at pH 4 using sago and tapioca starch. At pH 4, tapioca and sago starch removed 22.5% and 25% of COD respectively. Overall tapioca starch showed better removal percentage of turbidity compared to sago starch throughout the experiment study. Generally, the usage of natural polymers as coagulants is good for turbidity removal; however, it did not work well on COD removal.

    The aim of this research was to extract cellulose from office paper waste and converted into carboxymethyl cellulose (CMC) based flocculant to treat methylene blue (MB) dye solution. The yield of extracted cellulose obtained was 62.17%. Three different CMC samples were prepared. Degree of substitution (DS) for CMC-1 is 0.6585, CMC-2 is 0.8124 and CMC-3 is 0.8946. This proved that CMC are substituted into cellulose structure due to the DS of the commercial CMC are in the range of 0.4 to 1.5. The coagulation flocculation process of the MB dye shows that the CMC-3 was effective for methylene blue dye removal with highest percentage (98.14%) at pH 9.0, flocculant dosage of 210 ppm with 100 ppm MB concentration solution.

    This study is done to find the alternatives to solve the water pollution problem. The common ways to treat polluted water is by using alum. However, the usage of alum as conventional coagulant had caused the formation of sludge that can pollute the water and also cause illness. Tamarind seed was chosen as the alternative because it is naturals, non-toxic, and 100% biodegradable sources. In this study, the research was done in two parts, there are tamarind seed extraction by using different extraction solutions and the jar test. The extraction solution that was used were sodium chloride, potassium chloride and distilled water. In jar test, synthetic turbid water with turbidity range from 200 to 220 NTU was used to determine the effectiveness of tamarind seed as natural coagulant. Form the results obtained, sodium chloride extract achieved the highest percentage or turbidity removal with the percentage 91.32% with the dosage 25mg/L at pH 6, while the distilled water extract obtained the lowest percentage of turbidity removal with the percentage 56.60 % with the dosage 30mg/L at pH 3. As a conclusion, tamarind seed can be used as a natural coagulant in the treatment of polluted water.

    Lead (Pb) is one of the top-heavy metal pollutants often encountered in industrial wastewater. The presence of high levels of Pb in the environment may cause long-term health risks to humans. This study was focused on the removal and stripping of lead solution using liquid-liquid extraction (LLE) process. LLE was conducted using three types of extractants with sulphuric acid, H2SO4 as a stripping agent. Experimental parameters studied were types of extractant bis(2-ethylhexyl) phosphate (D2EHPA), trioctylamine (TOA) and tributylphosphate (TBP) and concentration of extractant (0.005, 0.05 and 0.5 M) and types of diluents (kerosene and toluene) respectively. The result indicates that, D2EHPA shows a good performance for removal of Pb compared to TOA and TBP where the highest extraction rate of lead was 93.92 %. Meanwhile, TBP shows the highest stripping rate of lead which is 93.57 %. Kerosene was found to be the best diluent compared to toluene. Overall, the optimum Pb extraction and stripping was obtained at 0.5 M D2EHPA and 0.005 M TBP with 250 rpm stirring speed, 5 min stirring time, 0.5 M H2SO4 and treat ratio 1:1. This LLE process has a good potential to aid in low-cost and environmentally friendly.
