Removal efficiency of anionic and nonionic surfactants from chemical wastewater by a treatment plant using activated carbon adsorption and coagulation precipitation processes

Permasalahan air limbah di Indonesia merupakan isu pencemaran lingkungan yang strategis dalam pembangunan berkelanjutan, baik yang bersumber dari pemukiman penduduk maupun unit usaha perkantoran. Tingginya kandungan organik terlarut di dalam air limbah dapat menyebabkan penurunan intesitas masuknya cahaya matahari yang dibutuhkan oleh mikroorganisme fotosintetik dan berdampak pada penurunan kualitas badan air. Tujuan dari penelitian ini yaitu merencankan pembangunan unit Instalasi Pengolahan Air Limbah (IPAL) domestik di Kantor Pusat PT. Pertamina Marketing Operation Region (MOR) V Surabaya dengan menggunakan kombinasi unit biofilter aerobik dan adsorpsi karbon aktif beserta perhitungan volume bangunan dan Rencana Anggaran Biaya (RAB) yang dibutuhkan. Teknologi pengolahan ini dipilih karena memiliki keunggulan dalam meremoval kadar pencemar organik dengan tingkat efisiensi yang tinggi dan kebutuhan lahan yang tidak terlalu luas. Metode penelitian menggunakan data sekunder yang diperoleh dari data perusahaan berupa debit pemakaian air bersih, layout kantor, data kualitas air limbah, serta informasi lain yang terkait dengan perencanaan. Hasil penelitian yang didapat berupa gambar desain (DED) unit IPAL, dimensi total bangunan pengolah seluas 34m2(P=17m dan L=2m), spesifikasi bahan yang digunakan, serta rencana anggaran biaya yang dibutuhkan untuk pembangunan kontruksi unit IPAL yaitu sebesar Rp243.136.020,00. Perencanaan ini juga ditunjang dengan panduan dalam operasional dan perawatan unit IPAL. Kata kunci: Adsorpsi karbon aktif, air limbah domestik, biofilter aerobik, desain IPAL. The problem of wastewater in Indonesia is a strategic issue of environmental pollution in sustainable development, both sourced from residential areas and office business units. The high dissolved organic content in wastewater can cause a decrease in the intensity of sunlight needed by photosynthetic microorganisms and have an impact on the quality of water bodies. The purpose of this study is to plan the construction of a domestic Waste Water Treatment Plant (WWTP) at the Head Office of PT. Pertamina Marketing Operation Region (MOR) V Surabaya using a combination of aerobic biofilter units and activated carbon adsorption along with the calculation of building volume and the required Budget Plan. This processing technology was chosen because it has advantages in renovating organic pollutant levels with a high level of efficiency and land requirements that are not too broad. The research method uses secondary data obtained from company data in the form of debit of clean water usage, office layout, waste water quality data, and other information related to planning. The results obtained in the form of design drawings (DED) of WWTP units, the total dimensions of the processing plant area of 34m2 (P = 17m and L = 2m), as well as the material specifications used, as well as the budget plan required for the construction of WWTP unit construction is Rp243. 136,020.00. This planning is also supported by guidelines in the operation and maintenance of WWTP units. Keywords: Activated carbon adsorption, aerobic biofilter, domestic wastewater, WWTP design.

Start Up

To evaluate the performance of the biological activated carbon filters at the Sainte-Rose water treatment plant in Ville de Laval (Québec), water and carbon samples were taken over a period of 150 days. Sampling began 1 year after filter start-up. The filters were then in a pseudo-equilibrium state. During winter, the removal rate of organic material is reduced because of lower water temperatures which affect bacterial activity. Bacterial density in the upper layers of the filter is influenced by temperature variations. During the warm season, bacteria counts are higher in the upper layer of the carbon, in the filter effluent, and in the backwash water. For equal carbon masses, bituminous carbon and peat-based extruded carbon have similar removal rates. However, for equal volumes, bituminous carbon is more efficient. Key words: biological activated carbon, adsorption, filtration, drinking water, organic matter.

Single Process

This study was carried out to increase the treatment efficiency through the improvement of the conventional biological process, and to propose the optimal treatment direction. The optimal treatment conditions were derived based on the results of the spike damage tests in each single process. The removal efficiency of micropharmaceuticals was further increased when an ozone treatment process was added to the biological process compared to the single process. The soil and activated carbon adsorption process was introduced in the post-treatment to remove the micropharmaceutical residues, and the removal efficiency of the pharmaceduticals in the final effluent was more than 85% in spike damage experiment. In particular, the continuous process of biological treatment-ozone-adsorption could ensure the stable treatment of micropharmaceuticals, which had not been efficiently removed in the single process, as it showed more than 80% removal efficiency. Therefore, it is expected that the addition of the ozone oxidation and activated carbon adsorption process to the existing sewage treatment facilities can contribute to the efficient removal of micropharmaceuticals.

Metal Pb(II) is one of the pollutants that causes water pollution and impacts ecosystem damage. Pb(II) metal waste is toxic and biomagnification, so it harms human health. The combination of electrocoagulation and adsorption processes is an efficient and effective alternative in removing Pb(II) metal in wastewater. In this study, the wastewater treatment process is carried out in batch using electrocoagulation with aluminum electrodes and followed by activated carbon adsorption. This research aimed to analyze the effect of electrical voltage in electrocoagulation, adsorption time, and adsorbent dose on reducing Pb(II) concentration. Electrocoagulation and adsorption processes were used variations of electrical voltage (10, 20, 30 V), adsorption times (15, 30, 45 minutes), and adsorbent doses (2,5, 3,3, 4,1, 5 g/L). The research showed that the combination of electrocoagulation and adsorption could significantly reduce Pb(II) concentration in wastewater. Increased electrical voltage, adsorption time, and adsorbent dose lead to increased Pb(II). The maximum removal efficiency of Pb(II) metal was obtained under voltage of 30 V, 45 minutes adsorption time, and 5 g/L adsorbent dose. This condition resulted in removal efficiency Pb(II) of 96,01%.

Carbon Adsorption

Objectives : This study investigated the removal of dissolved organic materials by coal-, coconut-, and wood-based activated carbons to assess the addition of an activated carbon process to a publicly owned treatment works (POTW).Methods : We assessed the removal of total organic carbon (TOC) by each process in the POTW, and examined the removal of TOC and UVA254 upon adding different amounts of coal-, coconut- and wood-based activated carbons (50, 100, 200, 300, and 400 mg/L) with various contact time (10, 20, 30, 60, 120 min).Results and Discussion : Approximately 80% of TOC was removed throughout the POTW compared to the influent. The activated carbon adsorption tests of coagulated wastewater revealed that the removal rate of TOC and UVA254 from coal-based activated carbon was higher than those of coconut-based and wood-based activated carbons. The removal rate of dissolved organic materials was highest in ozone treated wastewater in all types of activated carbons, followed by ultraviolet disinfected wastewater and coagulated wastewater.Conclusions : It was possible to remove an additional 35-55% of dissolved organic materials upon addition of activated carbon to the treated wastewater although the removal depends on the material of the activated carbon, the injection amount, and the contact time. If an activated carbon process is adopted to the POTW, it can meet the effluent water quality standards (TOC).
