“…As such, direct photolysis on its own is not an effective for removing pharmaceuticals from wastewater. Alternatively, photolysis coupled with Fe (III) and H 2 O 2 or TiO 2 can remove over 98 % of pharmaceuticals including estrogens (Feng et al, 2005;Benotti et al, 2009).…”

“…The use of PMRs shortened the process route for catalyst recovery, reduced the size of installation, and also enabled the continuous production with low energy consumption (Mozia, 2010). In this regard, PMRs were considered to be a promising technology in natural organic matter (Choo et al, 2008), pharmaceuticals and endocrine disrupting compounds removal (Benotti et al, 2009), municipal wastewater (Mozia et al, 2014), and dye wastewater treatment (Mozia et al, , 2009.

h i g h l i g h t s g r a p h i c a l a b s t r a c tFor the first time, homogeneous catalytic ozonation and membrane distillation were coupled in a membrane reactor. Organics and salts were efficiently removed and the homogenous catalyst was almost 100% recovered simultaneously. Membrane fouling was effectively mitigated compared to MD process.a r t i c l e i n f o b s t r a c tA novel catalytic ozonation membrane reactor (COMR) coupling homogeneous catalytic ozonation and direct contact membrane distillation (DCMD) was developed for refractory saline organic pollutant treatment from wastewater. An ozonation process took place in the reactor to degrade organic pollutants, whilst the DCMD process was used to recover ionic catalysts and produce clean water. It was found that 98.6% total organic carbon (TOC) and almost 100% salt were removed and almost 100% metal ion catalyst was recovered. TOC in the permeate water was less than 16 mg/L after 5 h operation, which was considered satisfactory as the TOC in the potassium hydrogen phthalate (KHP) feed water was as high as 1000 mg/L. Meanwhile, the membrane distillation flux in the COMR process was 49.8% higher than that in DCMD process alone after 60 h operation. Further, scanning electron microscope images showed less amount and smaller size of contaminants on the membrane surface, which indicated the mitigation of membrane fouling. The tensile strength and FT-IR spectra tests did not reveal obvious changes for the polyvinylidene fluoride membrane after 60 h operation, which indicated the good durability. This novel COMR hybrid process exhibited promising application prospects for saline organic wastewater treatment.

“…Material ini memiliki harga yang sangat murah dan spektrum serapan yang lebih lebar dibanding TiO2 murni [11]. Sebagai material penyangga digunakan polimer PP lembaran (supplier lokal) dan polimer PP butiran (Polyolefin Company Pte.Ltd., Singapore) (massa jenis 0,817 g/cm3, diameter rata-rata 3 …”

“…Meskipun demikian, penggunaan material ini untuk menghancurkan kontaminan dalam air limbah memiliki kendala karena massa jenisnya yang membuatnya tenggelam dalam air, sehingga proses aktivasinya dengan cahaya mengalami kendala. Selain itu, penggunaan material ini dengan mendispersikannya secara langsung dalam air limbah juga memiliki kendala: (1) dibutuhkan post-treatment untuk memisahkan partikel TiO2 dari air yang dibersihkan, yang membutuhkan waktu dan biaya yang tidak sedikit [3,4], (2) terjadinya penggumpalan partikel-partikel TiO2 dalam air terutama dispersi dengan konsentrasi tinggi [5].…”

Aktivitas Fotokatalitik TiO2 yang Dilapiskan pada Polipropilena Berbentuk Lembaran dan Butiran

ABSTRAKPolimer polipropilena (PP) berbentuk lembaran dan butiran telah digunakan sebagai material pelampung untuk katalis TiO2. Proses pelapisan serbuk TiO2 pada permukaan polimer menggunakan metode kombinasi elektrostatik dan pemanasan (untuk polimer lembaran) dan metode thermal milling (untuk polimer butiran). Pengujian aktivitas fotokatalitik dilakukan terhadap larutan Metilen Biru (MB) 25 ppm sebanyak 300 ml. Dengan menggunakan parameter optimal jumlah katalis diperoleh bahwa TiO2 yang dilapiskan pada polimer PP berbentuk lembaran memiliki aktivitas fotokatalitik yang lebih tinggi dibandingkan katalis yang dilapiskan pada polimer PP berbentuk butiran.Kata-kata kunci: Aktivitas fotokatalitik, TiO2, Metilen biru © Institut Teknologi Bandung.
