“…A combination of chemical oxidation with ozone removed 90% of wood extractives and 50% of the COD from TMP wastewater at 150 ℃. Athanasopoulos [18] suggested post treatment methods such as electrolysis or ozonation to reduce COD. Nakamura et al [19] reported on efficient degradation of lignin using a combined treatment of ozone and activated sludge process.…”

Papermaking industry generates a considerable amount of wastewater including varieties of pollutants. This paper reviews the ordinary processes of treating papermaking wastewater, and introduces the merits and demerits of these processes. The latest technologies are summed up. A forecast is made through all the methods in recent years. The waste to waste process is particularly promising because of its remarkable economic and environmental benefits.

“…Based on this fact, various biological wastewater treatment processes have been globally applied and wastewater recycling for use has become a solution for sustainable living (Athanasopoulos 2001;McKinney 2004;Lofrano et al 2006). Knowledge of the mierobial populations adapting the sludge environment and their interaction with the environment needs to be harnessed for optimum evaluation and functioning of biological wastewater treatment plants.…”

Though culture-independent methods have been used in preference to traditional isolation techniques for characterization of microbial community of wastewater treatment plants, it is difficult to widely apply this approach in resource-poor countries. The present study aimed to develop a test to identify the culturable portion of bacterial community in a high-strength wastewater. Wastewater samples were collected from nitrification-denitrification and settling tanks of the treatment plant of Elmo Leather AB tannery located in Borås, Sweden. After cultivating on nutrient agar with the optimal dilution (10⁻²), phenotypic and biochemical identification of the bacteria were done with colony morphology, Gram reaction, growth on MacConkey, phenylethanol media, triple sugar Iron agar slants, catalase and oxidase tests. Biochemical grouping of the isolates was done based on their test results for MacConkey, phenylethanol media, triple sugar Iron agar and oxidase test reaction. From the biochemical groups, isolates were randomly selected for API test and 16SrRNA gene sequencing. The isolates from the denitrification, nitrification tank were identified to be Paracoccus denitrificans (67%), Azoarcus spp (3%) and Spingomonas wittichii (1%). From the settling tank, Paracoccus denitrificans (22%), Corynebacterium freneyi (20%) and Bacillus cereus (1%) were identified. The grouping based on biochemical test results as well as the identification based on sequencing has shown coherence except for discrepancies with the API test. The preliminary implications of the grouping based on culture-based characteristics and its potential application for resource-limited environmental microbial studies is discussed.

In the present study, chemical oxygen demand (COD) removal by packed‐columns of activated carbon (AC) derived from two different materials (coal activated carbon, CAC and wood activated carbon, WAC) is reported as part of an on‐site wastewater treatment system for handling small volumes of wastewater generated at wood‐floor industries for which there are no proper on‐site treatment options available in the market. The performance of the sorbents, the effect of bed depth (0.19 and 0.57 m) and volumetric load (0.10 and 0.24 m h−1) on the breakthrough curve of sorption systems were studied. The results indicated the feasibility of using both ACs to treat these wastewaters. At the bed depth (0.57 m), volumetric load (0.24 m h−1), and 30% breakthrough, CAC and WAC showed treatment capacity of 40.5 L kg−1 in 250 h and 23.8 L kg−1 in 63 h, respectively. This indicated that CAC requires longer retention times to reach a performance similar to WAC. The experimental data was fit into the bed depth‐service time model showing that under the same conditions, CAC had higher maximum sorption capacity (N0) than WAC. Moreover, thermal regeneration at 500°C temperature could be a cost‐effective procedure since the reuse of spent AC through such regeneration process for further treatment could still achieve 90% of the initial sorption capacity, reducing then costs for the use of new sorbents and also the need for waste disposal.
