GLYPHOSATE AND TURBIDITY REMOVAL IN WATER CONDITIONS BY CLARIFICATION WITH TANFLOC

With the progress in the agriculture sector, improper domains of pesticides, herbicides, and insecticides have grown, which have been negatively affected the environment until the present day. Therefore, the present work has as objective to evaluate the efficiency of the natural coagulant Tanfloc in the clarification stage with respect the herbicide glyphosate removal and the turbidity parameter by using jar test with different pH conditions and coagulant concentration. As a result, was obtained that for the pH range of 5-5.5 the natural coagulant has shown more efficient, with a glyphosate percentage removal of approximately 98.0% using low concentrations and turbidity removal of 21.69%. On the other hand, for the pH range of 6.8 to 7.3, the coagulant has not shown profitable results, considering that, for some concentrations, it was not possible to detect the herbicide removal. In the concentrations that were detected removal, the average glyphosate percentage removal was approximately 89% and an average of 20.24% of turbidity removal. In summary, although the natural coagulant has not shown remarkably efficient in the neutral pH range, the product may be considered an alternative device in water treatment with the respect of the use of metallic coagulants, which produce sludge with chemistry characteristics that may negatively affect the environment.

Foliage Plant

The effectiveness of dragon fruit foliage as a natural coagulant for treatment of concentrated latex effluent was investigated and compared with ferric sulfate, a chemical coagulant. Dragon fruit is a round and often red-colored fruit with scales-like texture and is native to south American countries which is also cultivated and heavily marketed in southeast Asian countries. Its foliage represents a part of its overall plant system. Latex effluent is one of the main byproduct from rubber processing factories in Malaysia. Three main parameters investigated were chemical oxygen demand (COD), suspended solids (SS), and turbidity of effluent. Coagulation experiments using jar test were performed with a flocculation system where the effects of latex effluent pH as well as coagulation dosage on coagulation effectiveness were examined. The highest recorded COD, SS, and turbidity removal percentages for foliage were observed for effluent pH 10 at 94.7, 88.9, and 99.7%, respectively. It is concluded that the foliage showed tremendous potential as a natural coagulant for water treatment purposes. The foliage could be used in the pretreatment stage of Malaysian latex effluent prior to secondary treatment.

The Comparative Study

This paper is focused on the comparative study of cactus powder, Alum, and their combination of physiochemical analyses of water sample such as TDS, pH, conductivity, salinity, and turbidity using jar test. The result indicated that percentage removal of turbidity from turbid water sample increased from 23.9% to 54% and 28.46% to 58.2% as dose increased from 0.50 to 3.50 g for both cactus powder and Alum, respectively. Cactus powder also has a marginal effect on pH value (7.33 at 0.50 g, 7.49 at 1.50 g, 7.57 at 2.50 g, and 7.57 at 3.50 g) as compared to the usage of chemical coagulants (Alum). The salinity was increased from 0.4% to 0.69 % and 0.39% to 0.98% as the dose of cactus powder and Alum increased from 0.50 g to 3.50 g, respectively. The result revealed that cactus powder is more effective in pH upholding, TDS maintenance, and salinity removal than Alum, but their combination is the most effective in terms of turbidity removal, reduction of salinity, reduction of conductivity, and reduction of TDS and has a marginal effect on dissolved oxygen (DO) value. In conclusion, the combination of Alum and cactus powder is more effective for turbidity removal, salinity removal, and pH and conductivity upholding than either of them used individually.

Controlled Conditions

Samples of turbid water prepared under laboratory controlled conditions were tested using natural coagulant-flocculant Moringa oleifera seeds from Burundi, Central Africa, and from Mahajanga, Madagascar. Coagulation-flocculation and sedimentation experiments were conducted using jar test equipment. For these tests, 5% Moringa oleifera solutions (w/w in water) were prepared using shelled and non-shelled seeds from the aforementioned countries. The results show that, in both cases, the shelled seeds provide much higher turbidity removal than the non-shelled ones. In addition, the volume of sludge produced was approximately 30% of that of conventional coagulants such as alum. Finally, it was concluded that seeds from Burundi were of superior quality than those of Madagascar. In fact, higher dosages of these seeds, of up to four times, were required in order to attain the same level of turbidity as the Burundi seeds.

Abstract This work showed the whey proteins solubility curves, according with temperature and pH conditions. The product constituted of a whey protein isolate obtained from cow milk (ALACENTM 895), acquired by New Zeland Milk Products Ltd. There is a straight analogy between fouling and protein unfolding when milk derived fluids are processed in equipments of heat exchangers, where whey proteins are unfolded in an irreversible way, exposing hidrophobic groups, and they become insoluble and form aggregates. An integrated study was conducted on the effects of temperature and pH on the solubility of whey proteins. The solubility was determined experimentally in the temperature range of 40-90 °C, and pH range of 5.0 - 6.8. The results showed that, both the temperature and pH influenced in the protein solubility; besides, the solubility values were minimum at the pH 4.0 for all temperature values. It was also observed that solubility decreased with temperature increased.

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
