The possibility of treatment of wastewater from bioethanol production by aluminium sulfate and natural coagulant extracted from common bean seed was studied. The highest coagulation activity at pH 6.5 is reached with analum dose of 1 g/l, but only a little lower coagulation activities were obtained by the dose of 0.05 and 0.10 g/l, which is more favorable for economic and environmental reasons. When natural coagulant from common bean was applied the highest coagulation activity, 14.3%, at pH 6.5 is reached with a dose of 0.5 ml/l. However, when common bean natural coagulant was used simultaneously with alum, the highest turbidity removal resulting in 24% coagulation activity was achieved and this was more efficient than when alum or natural coagulant were used.

Natural coagulants from a crude water extract of common bean seed showed very good efficiency of turbidity removal from water of ~89 % under optimal coagulation conditions, which were determined using response surface methodology (RSM). However, they also increased the content of organic matter in treated model water by ~66 %, which is the main drawback of usage of natural coagulants, in general. Thus, ultrafiltration was applied for processing of the crude water extract in order to separate biomolecules, which exhibit the coagulation activity. Four fractions obtained by ultrafiltration were applied in coagulation tests under the same conditions as the crude extract, and the 4th fraction (molecules with molecular weights >30 kDa) with the predominant content of proteins with molecular weights 50 - 60 kDa, achieved almost as high efficiency of turbidity removal (75 %) as the crude extract. At the same time, the content of organic matter in treated water increased just for 16 % in comparison to the blank (model water processed in the same way but without coagulant). After optimization of process parameters by RSM for usage of the 4th fraction, the coagulation activity increased further to 80 %.

Potential Alternative

Distillery wastewaters have a great pollution potential, and pollution caused by them is one of the most critical environmental issues. This study is concerned with the coagulation efficiency of a new, environmental friendly, natural coagulant extracted from common bean seeds in the primary treatment of distillery wastewater in the bioethanol production from sugar beet juice. Active coagulation components were extracted from ground seeds of common bean with 0.5 mol/L NaCl. The obtained raw extract was used as a coagulant. The coagulation efficiency was measured by jar test at different pH values of wastewater, and a decrease in organic matter content was determined. The experiments confirmed that natural coagulant from common bean could be successfully used for the treatment of extraction juice distillery wastewater. The highest coagulation efficiencies were achieved at the pH 5.2 with a coagulant dose of 30 mL/L, and at the pH 8.5 with a coagulant dose of 5 mL/L, and they were 64.71% and 68.75% respectively. These encouraging results indicate that natural coagulant from common bean seeds is a potential alternative to conventional chemical coagulant/flocculant agents for treatment of wastewaters.

ABSTRACTThe ability of tapioca to act as natural coagulants (biocoagulants) was tested using artificial water. As turbidity was added as kaolin. This research aimed to determine the compounds and or groups that act as natural coagulant and to describe the mechanism of flocculation: extraction which yields tapioca extract and ion exchange which yields ionic tapioca. Coagulation process was performed at three different initial turbidities, i.e. 50 NTU (low turbidities), 150 NTU (middle turbidities) and 300 NTU (high initial turbidites). At the same condition (coagulant dose 20 ppmv, pH 5), ionic tapioca yield better turbidity removal compared tapioca extract i.e 11.2% at low initial turbidites; 2.4% at middle initial turbidities and 12.8% at high initial turbidities. FTIR analysis  showed that tapioca extract and ionic tapioca contained of carboxyl, hydroxyl and amides groups which  can act as active components on coagulation process. The presence of those groups caused positive and negative charges (amphoter). Coagulation process ran efficiently at pH 5 because the isoelectric point is obtained at that condition.Keyword : bio coagulants, coagulation,  coagulant agents, ionic tapioca, tapioca extract,ABSTRAK Kemampuan tepung tapioka sebagai koagulan alami (biokoagulan) telah diuji dengan menggunakan limbah artifisial dari kaolin. Penelitian ini bertujuan untuk menentukan senyawa atau gugus yang berperan sebagai biokoagulan dan menjelaskan mekanisme flokulasi yang terjadi. Perlakuan awal tapioca sebelum digunakan sebagai koagulan adalah ekstraksi yang menghasilkan ekstrak tapioka  dan pertukaran ion  yang menghasilkan tapioka ionik. Proses koagulasi dilakukan pada 3 macam kekeruhan awal yaitu 50 NTU (kekeruhan rendah), 150 NTU (kekeruhan sedang) dan 300 NTU (kekeruhan tinggi). Pada kondisi operasi yang sama (dosis 20 ppmv dan pH 5), tapioka ionik memberikan efisiensi penurunan kekeruhan yang lebih tinggi, yaitu sebesar 11,0% pada kekeruhan awal 50 NTU; 2,4% pada kekeruhan awal 150 NTU dan 12,8% pada kekeruhan awal 300 NTU. Hasil analisa FTIR menunjukkan bahwa ekstrak tapioka dan tapioka ionik mempunyai gugus karboksil (-OH), gugus karboksil (-COOH) dan gugus amida (-CONH2). Keberadaan ketiga gugus tersebut menyebabkan biokoagulan ini memiliki muatan positif dan negatif sekaligus (amfoter). Proses koagulasi berjalan dengan efisien pada pH 5 karena titik isoelektrik diperoleh pada pH tersebut. Kata kunci : biokoagulan, koagulasi, agen koagulan, ekstrak tapioka, tapioka ionik

High Turbidity

High turbidity in water not only will reduce the quality of water itself but it can give impact to the ecosystem as well. In water treatment, coagulation and flocculation are the process involved in removing turbidity. Chemical coagulant such as aluminium sulfate (Alum) and ferric chloride are effective way and widely used in order to remove the turbidity in water. However, these chemical coagulants have a side effect in spite of the effectiveness in turbidity removal, the usage of alum and other chemical coagulants bring concerns due to its impact to the environment, human health and economy. Therefore, natural coagulant is another alternative for turbidity removal in water treatment. Natural coagulant is a plant-based coagulant which can be used to replace chemical coagulants. These coagulants are generally cheaper and safer than chemical counterparts. This research is conducted to compare the effectiveness of natural based coagulant made from Psophocarpus tetragonolobus and chemical coagulant in improving the quality of raw water. Findings from this study showed P. tetragonolobus can remove turbidity up to 60 percent with 40 ml, 1% solution. Therefore, P. tetragonolobus can be considered as a potential resource for natural coagulant.

Moringa Oleifera Seed

The plant-based natural coagulant has the potential to substitute the chemical coagulant in the water treatment process. In this work, the potential of plant-based natural coagulants in the ability of turbidity removal was identified. The Moringa oleifera seed was selected for the batch analysis test such as pH, contact time, agitation, and dosage. The high alkaline water decreases the effectiveness of plant-based natural coagulants. The agitation and contact time show the importance of the coagulation process. The optimum turbidity removal rate in pH is 4, the contact time is 60 seconds and 3000 seconds for coagulation and flocculation, respectively, the agitation is 300 RPM and 30 RPM for coagulation and flocculation, and lastly, the dosage is 10 g of Moringa oleifera seed. Finally, the plant-based natural coagulants demonstrated the ability to remove turbidity and could be used in place of chemical coagulants.

Natural coagulants are of organic nature and can increase organic load of treated water, thus they require purification in order to remove compounds that do not have coagulation activity. In this work natural coagulant was extracted from 50 g L-1 of ground common bean with 0.5 mol L-1 NaCl. Proteins from this crude extract were precipitated by adding ammonium-sulphate. After precipitation, separation and resolution of proteins, further purification was done by anion-exchange resin Amberlite IRA 958 Cl in batch process. Partially purified coagulant eluted by 2 mol L-1 NaCl solution achieved the highest coagulation activity of 53.3 % at dose of 1 mL L-1 although it contained the lowest amount of proteins, but just slightly lower coagulation activity of 49.8 % was achieved at more than 5 times lower dosage of the same fraction. Organic load in treated water when purified fraction was applied as coagulant was almost 4 times lower than in case of crude extract as coagulant.

Investigation of an extraction procedure of protein coagulants from common bean seed regarding concentration of NaCl and pH was performed. High values of protein concentration and coagulation activity in crude extract (9.19 g/l and 23.9%, respectively) were obtained when the extraction was performed using 0.5 mol/l NaCl and water as solvent, which represents an advantage for economic and environmental reasons. Crude extract of common bean seed was purified by precipitation at two different percentages of (NH4)2SO4 saturation, followed by batch ion-exchange chromatography. The highest obtained coagulation activity, 45%, was determined in fraction that was eluated at 1.75 mol/l NaCl from resin loaded with proteins precipitated upon 80-100% (NH4)2SO4 saturation. High values of coagulation activity showed by some eluates suggest their application as natural coagulant for water purification. .
