Post-treatment of plywood mill effluent by Multi-Barrier Treatment: A pilot-scale study

Application of Catalytic Wet Peroxide Oxidation for Industrial and Urban Wastewater Treatment: A Review

“…CWPO with carbon materials as catalyst is especially efficient as a post-treatment step when applied after Fenton/photo-Fenton and/or UV/H 2 O 2 processes due to the high efficiency of H 2 O 2 elimination and the removal of possibly toxic pollutants [42]. Therefore, CWPO with GAC as catalysts were efficient in the decrease of the initial TOC and COD of industrial wastewater effluent (previously treated by UV/H 2 O 2 process) from 27 to 16.7 mg/L and from 59 to 26.6 mg/L, respectively, only after five minutes of contact time with GAC [66]. It should be noted that residual H 2 O 2 after the UV/H 2 O 2 process was sufficient for CWPO.…”

“…The initial concentration of H 2 O 2 used for CWPO applied as post-treatment step for industrial and urban wastewater effluents (in reviewed papers) varied between 79.3 mg/L and 3.4 g/L. It should be mentioned that the high efficiency of H 2 O 2 consumption is one of the main advantages of CWPO [49], so, after the post-treatment of industrial wastewater effluents by CWPO using GAC, full consumption of H 2 O 2 was reported [42,43,66,67]. Interestingly, very short contact time (between 2.3 and 6 min) was sufficient for the significant elimination of organic pollutants and complete decomposition of H 2 O 2 [42,43,66,67].…”

Interestingly, very short contact time (between 2.3 and 6 min) was sufficient for the significant elimination of organic pollutants and complete decomposition of H 2 O 2 [42,43,66,67]. Complete consumption of hydrogen peroxide during CWPO is extremely beneficial from a practical point of view due to the absence of residual hydrogen peroxide in wastewater effluent, so the possible toxicity of the final effluent (when CWPO is applied as post-treatment step) might be avoided.…”

Wood-Based Panel Industry Wastewater Meets Microbial Fuel Cell Technology

“…The currently obtained maximum power production of 9 W/m 3 is still not satisfactory, though when we take into account single-basin volume (ca. 2000 m 3 ) and the fact that there can be several basins in a single plant, we can obtain power production as high as ca. 300 kW from WHTW generated in one plant.…”

“…Wastewater from production of wood-based materials is usually highly polluted. Chemical oxygen demand (COD) values were measured in a wide range from 200 to 11,000 mg O 2 /L depending on the operation stage that generated the wastewater [3][4][5]. They contain a wide range of various substances among which wood degradation products, wood extractives, heavy metals or even surfactants introduced during cleaning processes can be found.…”
