Abstract

Cellulose contained in peanut shells which are agricultural waste is considered to be potential as an adsorbent for removing heavy metals. Therefore, it is necessary to analyze the capacity of absorbance or the ability of meshes in the continuous adsorption process in removing heavy metal Fe in well water. The feasibility of an agricultural waste related to its use as an adsorbent has also been studied in this study through characterization by FTIR test which aims to determine the presence of cellulose organic compounds that play a role in the process of heavy metal adsorption. While the study of adsorption capacity in this study uses a continuous process that is generally carried out by Thomas modeling. Where in this study a continuous adsorption process was carried out to obtain saturation time from the adsorption of peanut shells in absorbing Fe metal. So that the absorbance capacity obtained from the once used activated carbon peanut shell has been made. In this study, a continuous adsorption process was carried out with a mass variation of 250 gr and 500 gr. This continuous adsorption process is obtained. The highest price of Constant Thomas (Kth) and the price of absorbance capacity (qo) is using activated carbon peanut shells with the use of 500 grams following the Thomas equation model y = -0.1701x + 3.3142 with a correlation coefficient (R²) = 0.4767 while the breakthrough point was reached in the 60th minute after well water through the bed

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.
