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 application of sewage treatment in New Delhi should implement the treatment processes, which are easy to be operated and is not costly operational and avoid the complexity of the operating system of STP. The renewed interest in alternative onsite treatment technology by using a constructed wetland (CW). Canna lily, an ornamental plant that has an aesthetic value, is very suitable for an alternative plant for a constructed wetland. This study aims to observe the ability of canna lily for phytotechnology implementation in a constructed wetland. This study is known as a range-finding test (RFT), which served as a preliminary test. Observation is conducted by preparing variation concentration of wastewater; 25%; 50%; 75%; 100% and 0% as control, which was injected into the wetland. CW (60 cm long, 60 cm wide and 60 cm deep) contained gravel medium height 25 cm with a wastewater volume 3 L. Observation measured the height of the plant, the color of the leaf, and DO, and BOD concentration. The observation was conducted for about 25 days, in term of 15 days for range finding test and 10 days for acclimation. The results show that Canna lily could grow well, though it has some part of the withered leaf, reach height significantly, and indicated decreasing concentration of organic parameters. It is conjectured that Canna lily is very possible for a constructed wetland application.

Abstract

Laundry wastewater is one of the contributors to domestic wastewater since laundry services have been increasing in urban living, especially in big cities. Laundry wastewater may contain phosphate compounds, and the concentration should be reduced before discharge into water bodies. One of the easiest and friendly methods for removing phosphate in laundry wastewater is by using the adsorption process. Adsorption is influenced by the adsorbent material, and fly ash has been implemented as adsorbent due to its high capacity to adsorb pollutants. This study aims to observe the effect of adsorbent height in the column and the effect of flow rate to treat phosphate in laundry wastewater. This study applied Thomas modeling to determine the model for fly ash capacity as adsorbent. The results showed that the highest flow rate, 15 mL/min, and the highest fly ash height 20 cm gave the optimum removal of phosphate, about 98.63-99.22%. Besides, Thomas model obtained the value of the linear regression coefficient of 0.5415.

Abstract

The increase in the electroplating industry resulted in a large number of heavy metal wastes that are harmful to the environment, for example, hexavalent chromium waste. The Bintaro which contains cellulose is considered as a potential adsorbent to remove heavy metals. Therefore, a comparative study on the adsorption capacity of continuous adsorption was carried out in reducing the concentration of heavy metal Cr6+ in electroplating wastewater. The characterization itself can be done by testing the moisture content and ash content and SEM testing. The study of the adsorption capacity in a continuous process is generally carried out with Thomas modeling, where this research is carried out by a continuous adsorption process with variations in the adsorbent mass of 50 grams, 100 grams, 150 grams, 200 grams, and 250 grams. The best results were obtained to remove Cr6+ metal which was 94.4% in the Bintaro shell adsorbent type with a mass of 250 grams. The continuous adsorption process obtained the highest Thomas constant (Kth) value and the highest adsorption capacity (qo), namely using Bintaro shell activated carbon with a mass of 250 grams with an absorbance capacity value of 0.443mg / g. The results showed that the activated carbon of Bintaro shell showed that they were quite effective as adsorbents in the adsorption process to remove heavy metal Cr6+

Abstract

The high nitrate content in domestic wastewater can cause problems for the environment. Improved quality of processed wastewater can use biological treatment with oxidation ditch combined with microalgae Spirulina platensis. The growth process of Spirulina platensis requires nutrients such as nitrates. In the study, variations in aeration conditions (continuous aeration and intermittent aeration) were conducted to create anoxic conditions in oxidation ditch algae reactors. Observations were made for 5 days with the aeration process using a brush aerator rotation speed of 60 rpm. The results showed that the microalgae Spirulina platensis has the potential to be effective in degrading nitrate concentrations in domestic wastewater. In addition, intermittent aeration has a significant effect on nitrate degradation in domestic wastewater. This is indicated by a decrease in nitrate with a percentage removal of 73.71% from the initial nitrate concentration of 5.82 mg/l to 1.53 mg/l during intermittent aeration.

Abstract

Oxidation ditch (OD) is a tub used to treat wastewater by utilizing oxygen and microorganisms contained in it to determine its ability to reduce the release of organic substances. Oxidation Ditch Algae Reactor (ODAR) is a biological wastewater treatment that utilizes the symbiosis between algae and bacteria in water. The results of biological processes contain organic material called effluent organic matter (EfOM). This research aims to investigate the characterization of effluent organic matter (EfOM) produced from the Oxidation ditch (OD) process with and without algae both in continuous aeration (oxic) and intermittent aeration (oxic-anoxic) conditions in domestic household wastewater and microalgae Spirulina platensis. Characterizing effluent organic matter (EfOM) is a crucial thing to understand its ability to treat wastewater. Based on the analysis results, the characterization of effluent organic matter (EfOM) in the oxidation ditch process using an algae ratio of 1:1 in continuous aeration (oxic) conditions through the UV254 test was identified as containing the highest aromatic organic matter up to 59.68%. Meanwhile, without using algae with a 1:0 ratio of intermittent aeration (oxic-anoxic) conditions, the lowest decrease in aromatic organic matter content reached 34.79%.
