Pengaruh Kondisi Operasi Proses Pemekatan Litium Dari Geothermal Brine Sintetis Dengan Metode Direct Contact Membrane Distillation (DCMD)

نویسندگان

چکیده

Penggunaan lithium dalam pembuatan baterai meningkat secara signifikan beberapa tahun terakhir. Karena peningkatan kebutuhan lithium, maka diperlukan sumber litium yang dapat di eksploitasi. Target dari penelitian ini adalah untuk memekatkan konsentrasi sebelum dilakukan proses pemisahan lainnya. Perangkat DCMD menggunakan perbedaan tekanan uap dikedua sisi membran sebagai driving force. Larutan umpan divariasikan pada berbagai suhu dan laju alir sedangkan permeat dipertahankan 25 °C. Suhu 60, 50, 40 °C 420, 260, 180 ml/menit. Untuk mengurangi penyumbatan membran, digunakan geothermal brine sintetis. Penelitian telah menunjukkan bahwa operasi memberikan pengaruh pengkonsentrasian Kenaikan sistem adanya kenaikan retentate fluks dihasilkan. Hasil optimum diperoleh 60 dengan 420 Perolehan rerata tertinggi dicapai sebesar 7,3 LMH, ikuti 50 5,3 2,7 LMH. Selain juga nilai Liquid enter pressure (LEP) bar kekuatan menahan uap, sehingga tidak terjadi wetting selama proses.

Seawater Desalination for Production of Highly Pure Water Using a Hydrophobic PTFE Membrane and Direct Contact Membrane Distillation (DCMD)

Qatar’s primary source of fresh water is through seawater desalination. Amongst the major processes that are commercially available on the market, the most common large scale techniques are Multi-Stage Flash distillation (MSF), Multi Effect distillation (MED), and Reverse Osmosis (RO). Although commonly used, these three processes are highly expensive down to high energy input requirements and ...

Performance and fouling mechanism of direct contact membrane distillation (DCMD) treating fermentation wastewater with high organic concentrations.

In this study, direct contact membrane distillation (DCMD) was used for treating fermentation wastewater with high organic concentrations. DCMD performance characteristics including permeate flux, permeate water quality as well as membrane fouling were investigated systematically. Experimental results showed that, after 12hr DCMD, the feed wastewater was concentrated by about a factor of 3.7 on...

A scaling mitigation approach during direct contact membrane distillation

Membrane scaling during the treatment of aqueous solutions containing sparingly soluble salts by direct contact membrane distillation (DCMD) was investigated. The results reveal that membrane scaling caused by CaSO4 was more severe than that by CaCO3 or silicate. However, under the experimental condition used in this study and at feed and distillate temperature of 20 C and 40 C, respectively, C...
