    Karakterisasi Air Terproduksi Industri Migas Sebagai Sumber Daya Air Alternatif Di Kecamatan Minas, Kabupaten Siak, Riau
    (2018-03-12) Hardi, Maulana; Anita, Sofia; Ilham, Ilham
    Oil and gas exploration activities always produce follow-up materials that is produced water with the number of millions of barrels per day. Oil field produced water has a chemical composition with different concentrations depending on the geographical location, the depth of the formation, the method of oil lifting, and the age of oil production wells. The abundant production of produced water by the oil and gas industry makes the produced water into one of the potential water resources to be utilized by the community for daily needs, but now the produced water is still considered as industrial waste that is harmful to humans and can pollute the environment. To see the potential reuse of produced water by the community, a laboratory testing was conducted to characterize chemical composition of oil field produced water in Minas area, Siak Regency, Riau Province with parameters set forth in Government Regulation No. 82 of 2001 on the Management of Water Quality and Control of Water Pollution for water class 1 (drinking water). The laboratory testing parameters performed are grouped by physical, inorganic chemistry, radioactivity, and organic chemistry including pesticides. This study also includes laboratory testing for samples from drinking water refill retail and water well located in Minas community area to analyze the quality of drinking water source in community as well as blank for quality of produced water. The result of laboratory tests shows for samples from produced water have 17 of 46 parameters (37%) still not meet limit of standard water class 1. While the result for sample from drinking water refill retail has 4 of 46 parameters (9%) not meet limit of standard class 1 and sample from community well has 3 of 46 parameters (6%) not meet limit of standard class 1.

    PENGOLAHAN AIR TERPRODUKSI MIGAS DI KECAMATAN MINAS BERBASIS ADSORBSI LOGAM BORON DAN BARIUM MENGGUNAKAN ADSORBEN ALAMI

    The produced water (PW) is wastewater generated from the extraction of oil and gas production. The PW from Minas oilfiledis around 13.5 million m3 per day and contains metals thatare boron (B) = 7,46±0,13 mg/L as B3+and barium (Ba) = 1,43±0,11 mg/Las Ba2+. Both metal contents are over the quality standards according to PP. No. 82 in 2001 (max. 1,00 mg/L). PW is a potential source to supply the water needs of the society in Minas District. So that PW can be utilized, it needs an effective treatment method to reduce of B and Ba contents by adsorption. The natural adsorbents are used to adsorb and more available in nature are rice husk (RH), commercial charcoal (CC) and bentonite clay (BC). The present study was aimed at the reduction of B and Bain Minas oilfield PW using RH, CC, and BC as adsorbents via batch process. Variable applied were adsorbent dosage (1, 5, 10, and 20%w/v) and cantact time (3, 12, 24, and 48 hours). The optimum result was exhibited by adsorption process using CC with dosage = 20%w/v and detention time of 3 hours which reduced B up to 96,2% and Ba = 99,3%. Through this process, the PW after treatment containedB = 0,28±0,02 mg/L as B3+and Ba = 0,01±0,01 mg/L as Ba2+. According to PP. No. 82 in 2001, the B and Ba in the PW after adsorption process is lower than 1,00 mg/L (Class I). It is concluded the PW after adsorption treatment can be used as raw material for drinking water and other usages.
