Advanced oxidation processes for wastewater treatment: Optimization of UV/H2O2 process through a statistical technique

Experimental study of porous tubular catalytic membranes for direct synthesis of hydrogen peroxide

“…Although the reported absolute hydrogen peroxide concentrations with our system and the self-prepared catalytic membranes are still rather low for most technical H 2 O 2 applications, a possibility for use in UV combined waste water treatment seems to exist, where low H 2 O 2 concentrations are needed, normally in the range of 5 mmol L −1 with molar ratio H 2 O 2 /pollutant of 1 or lower [26][27][28]. Note also that, having in mind the literature data on the dense Pd membrane distributor concept (entries 5-7, Table 6), our catalyst productivity for the porous membrane contactor is up to 12 times higher (with high selectivity of 83%).…”

Photo-Fenton process as an efficient alternative to the treatment of landfill leachates

“…Advanced oxidation processes (AOPs) have been demonstrated to be innovative suitable technologies to remove organic compounds and ammonia-nitrogen [6,7] or to enhance the biotreatability of wastewaters because they are able to oxidize the refractory organic compounds into harmless substances and ultimately, lead to mineralization end-products such as carbon dioxide and water [8,9]. Therefore, they offer a particularly useful alternative for the treatment of effluents with high organic matter content.…”

EVALUATION OF UV/O3AND UV/H2O2PROCESSES FOR NONBIODEGRADABLE COMPOUNDS: IMPLICATIONS FOR INTEGRATION WITH BIOLOGICAL PROCESSES FOR EFFLUENT TREATMENT

“…For experiments with ozone, the flow of ozone was set at 3 g=hour. For experiments involving hydrogen peroxide, 4 mole of H 2 O 2 per mole of total organic carbon (TOC) was added; this dosage was based on our earlier study on optimization by Taguchi's orthogonal design (Chidambara Raj et al, 2005).…”
