Abstract

Dissolved organic matter (DOM), which is part of of natural organic matter or NOM, contained of carbon compound and can cause problems related to taste, odor, and disinfection by-products (DBPs) in water and treated water. Permanganate is strong oxidant and have been know its efficiency in oxidazing organic compound. Coagulation is most widely used in all water treatment plant due to its efficiency in removing suspended solid. The objectives of this study is to characterize and to remove natural organic matter in term of  DOM  in water through KMnO4 preoxidation, Al2(SO4)3 or FeCl3 coagulation, KMnO4 preoxidation followed by Al2(SO4)3 or FeCl3 coagulation. Raw water, which was taken from Jagir River in Surabaya, and treated water were measured quantitatively by using total organic carbon (TOC), ultraviolet at wavelength 254 nm (UV254) in order to know its aromatic properties. In addition, fourier transfor m infrared spectroscopy (FTIR) was used to identify the functional group of DOM in water and treated water. The results showed that raw water has high TOC concentration (6,9 mg/L) and mainly composed of aromatic (UV254 0.075 cm-1). The optimum result showed that TOC concentration and UV254 removed significantly into 4,2 mg/L and 0,0020 cm-1, respectively after preoxidation followed by FeCl3 coagulation. According to FTIR analysis, mostly single bond carbon such as C-O and C-H still exist in treated water. This results indicated that preoxidation-coagulation has a better performance than preoxidation only and coagulation only.

Abstract

Heavy metals are pollutant parameters that contain high toxicity and are dangerous which can accumulate in the tissues of living things. One of the heavy metals contained in wastewater is lead (Pb). This metal is included in the extremely toxic category which can cause health problems. One way to treat waste containing the heavy metal Pb is by bioremediation using microalgae (phycoremediation). In this study, phycoremediation used the microalgae Chlorella vulgaris and Nannochloropsis oculata, as well as a consortium of both. This study aims to determine the ability of each microalga and the consortium of the two microalgae in removing lead heavy metals. The phycoremediation potential was measured based on the ratio of microalgae varied (100:0, 50:50, and 0:100) and the concentration of Pb waste (1, 5, and 10 mg/L) within 14 days on a batch scale. The results showed that the microalgae Chlorella vulgaris in reactor 10B (100% Chlorella vulgaris, 0% Nannochloropsis oculata) was able to remove 85.0% from a concentration of 10 mg/L to 1,5 mg/L.

Studi ini bertujuan untuk meningkatkan kinerja sistem dust collector yang diterapkan di area Press PT XYZ, di mana sistem tersebut belum optimal dalam mengendalikan debu yang bertebaran di lingkungan kerja. Penelitian ini melibatkan studi literatur, pengamatan lapangan, pengumpulan dan analisis data, serta perancangan desain untuk merancang solusi yang tepat. Perancangan fokus pada desain tudung isap dengan memodifikasi bentuk, lokasi, kecepatan tangkap dan laju aliran yang melaluinya. Hasil perhitungan menunjukkan bahwa untuk laju aliran udara 703,925 cfm, kecepatan tangkap yang dibutuhkan adalah 726,631 fpm. Sedangkan untuk bentuk tudung berdiri bebas dengan flensa, kecepatan tangkap yang dibutuhkan adalah 167,864 fpm. Berdasarkan perbandingan dengan kondisi eksisting, bentuk tudung booth dengan luas bukaan 0,969 ft2 terhubung ke saluran dengan luas bukaan 0,313 ft2 merupakan pilihan yang sesuai. Lokasi tudung isap ditempatkan di bagian atas bukaan bin dengan jarak 0,656 ft dari bukaan tudung.

Abstract

The problem of domestic wastewater originating from restaurants is the largest contributor to organic wastewater in urban waters. Among them are waste water parameters, namely oil, and grease. Oils and grease are compounds that do not dissolve easily in water. However, it can be dissolved with non-polar organic solvents. The carbon chains of oils and grease are also long. So, it is difficult to decompose and takes a long time if processing uses the help of microorganisms. So, the alternative is to use physical-chemical processing. In this research, we tried using a static mixer and an impeller mixer. We conducted a systematic review of DAF techniques in wastewater treatment. We reviewed six indexed databases namely dissolved air flotation, microbubbles, wastewater treatment, and key operational and design parameters involved in the effectiveness of the flotation process. In this pre-treatment, the focus is on the withdrawal/discharge speed in collecting wastewater as a test and the effectiveness of mixing wastewater with coagulants and air pressure. These three aspects are used in equilibrium to achieve the optimum dose for the static mixer use scheme. Meanwhile, the impeller mixer scheme uses rotational speed in mixing with the coagulant, contact time, and Reynolds number to achieve the required turbulence. Apart from that, the use of electrical energy in the pump is also calculated in these two schemes. The results obtained were the amount of weight of oil and grease collected in the static mixer pretreatment of 9.12% w/v and the impeller mixer of 7.63% w/v and the results of the organic content of the Chemical Oxygen Demand (COD) parameter for the static mixer were 86.92 % and mixer impeller 78.86 %. From these results, static mixers have advantages over using impeller mixers in terms of the effectiveness of the oil and grease reduction process.
