“…However, a pre-treatment step such as acidification is needed for the removal of low molecular weight organics and inorganics like boron, and the utilization of RO process without a pre-treatment step cannot be effective and some post treatment processes may also be needed after the RO process to meet the required standard. [51] Treatment processes depend on the characteristics of produced water and these differ from well to well. Some experimental studies for determination of characteristics of produced water are required for designing a treatment process, relying solely on the literature is not recommended.…”

“…Divalent metals may be removed under specific operating conditions (Table 21) through biogeochemical processes including: precipitation through dissimilatory sulfate reduction, organic complexation with detritus, hydrolysis, and sorption to biotic and abiotic exchange sites (Hawkins et al 1997;Ford 1998;Murray-Gulde et al 2005a;Rodgers and Castle 2008). Organic constituents may be removed under specific operating conditions (Table 21) through processes including: biodegradation, sorption, photolysis, and volatilization (Hawkins et al 1997;Murray-Gulde et al 2003;Johnson et al 2008b;Rodgers and Castle 2008). The primary targeted pathway for removal of divalent metals (e.g.…”

Clemson University with Chevron as an industry partner developed and applied treatment technology using constructed wetland systems to decrease targeted constituents in simulated and actual produced waters to achieve reuse criteria and discharge limits. Pilot-scale and demonstration constructed wetland treatment system (CWTS) experiments led to design strategies for treating a variety of constituents of concern (COCs) in produced waters including divalent metals, metalloids, oil and grease, and ammonia. Targeted biogeochemical pathways for treatment of COCs in pilot-scale CWTS experiments included divalent metal sulfide precipitation through dissimilatory sulfate reduction, metal precipitation through oxidation, reduction of selenite to insoluble elemental selenium, aerobic biodegradation of oil, nitrification of ammonia to nitrate, denitrification of nitrate to nitrogen gas, separation of oil using an oilwater separator, and sorption of ammonia to zeolite. Treatment performance results indicated that CWTSs can be designed and built to promote specific environmental and geochemical conditions in order for targeted biogeochemical pathways to operate. The demonstration system successfully achieved consistent removal extents even while inflow concentrations of COCs in the produced water differed by orders of magnitude. Design strategies used in the pilot-scale and demonstration CWTSs to promote specific conditions that can be applied to designing full-scale CWTSs include plant and soil selection, water-depth selection, addition of amendments, and hydraulic retention time (HRT). These strategies allow conditions within a CWTS to be modified to achieve ranges necessary for the preferred biogeochemical treatment pathways. In the case of renovating a produced water containing COCs that require different biogeochemical pathways for treatment, a CWTS can be designed with sequential cells that promote different conditions. For example, the pilot-scale CWTS for post-reverse osmosis produced water was designed to promote oxidizing conditions within the first wetland cell for nitrification of ammonia, and the subsequent three cells were designed to promote reducing conditions for denitrification of nitrate. By incorporating multiple wetland cells in a CWTS, the conditions within each cell can be modified for removal of specific COCs. In addition, a CWTS designed with multiple cells allows for convenient sample collection points so that biogeochemical conditions of individual cells can be monitored and performance evaluated. Removal rate coefficients determined from the pilot-scale CWTS experiments and confirmed by the demonstration system can be used to calculate HRTs required to treat COCs in full-scale CWTSs. The calculated HRTs can then be used to determine the surface area or "footprint" of a full-size CWTS for a given inflow rate of produced water.

Abstrak: Air terproduksi merupakan produk sampingan dari proses produksi indutsri minyak dan gas. Kualitas air terproduksi beragam, namun secara umum memiliki konsentrasi total dissolved solid (TDS) yang relatif tinggi. Pada konsentrasi tinggi, Total Dissolved Solid (TDS) dapat menyebabkan perubahan rasa pada air, pengendapan mineral dan korosi. Teknologi wetland dapat menjadi alternatif pengolahan yang mudah diterapkan dan relatif murah. Penambahan aerasi diharapkan mampu meningkatkan efisiensi penyisihan TDS. Tujuan dari penelitian ini adalah untuk melihat pengaruh penambahan aerasi pada wetland, waktu detensi/waktu tinggal yang optimum, dan penambahan Cyperus nutans yang digunakan sebagai vegetasi terhadap penyisihan TDS dan parameter lainnya. Sejauh ini, hasil penelitian menunjukkan bahwa penambahan aerasi dapat meningkatkan efiensi penyisihan TDS dibandingkan dengan penelitian sejenis yang tidak menggunakan aerasi. Hasil penelitian menunjukkan bahwa efisiensi penyisihan TDS pada reaktor dengan penambahan aerasi lebih tinggi dibandingkan dengan reaktor yang diaerasi.
