Halogen-containing organic substances have a detrimental and toxic impact on the environment and human health due to their high stability, carcinogenic effects, and ability to accumulate when ingested. The production and release of these substances have significantly increased in recent decades, resulting in a lack of effective treatment technologies. Adsorbable organic halogens (AOX), a specific parameter used to monitor pollution, represents the total amount of chlorinated, brominated, and iodinated organics that can be adsorbed on activated carbon from various environments. This paper provides an overview of selected articles from the past three decades (1990–2023) focusing on the primary natural and industrial sources of AOX. It also evaluates different determination techniques and a variety of removal approaches based on biological, physical, chemical, and combined processes. Additionally, the limitations and efficiency of these approaches are briefly characterized. While biochemical and physical methods have been limited by financial constraints and reduced efficiency, biological, chemical, and physicochemical techniques have shown significant potential in improving water quality. This knowledge can be valuable for the development of alternative water treatment techniques and underscores the importance of sustainable water usage.

“…There are numerous SBR applications including traditional organic carbon, nutrient and toxic substance removals (Azimi et al 2005;Rahman et al 2007;Ong et al 2010;Pasukphun et al 2010;Muhamad et al 2011). Recently, modified SBR using fixed cells was developed and reported more successful removal efficiencies (Rahman et al 2007;Muhamad et al 2011). In the prior works, the attached cells onto plastic or activated carbon media were applied.…”

Fermented rice noodle production generates a large volume of starch-based wastewater. This study investigated the treatment of the fermented rice noodle wastewater using entrapped cell sequencing batch reactor (ECSBR) compared to traditional sequencing batch reactor (SBR). The yeast cells were applied because of their potential to convert reducing sugar in the wastewater to ethanol. In present study, preliminary treatment by acid hydrolysis was performed. A yeast culture, Saccharomyces cerevisiae, with calcium alginate cell entrapment was used. Optimum yeast cell loading in batch experiment and fermented rice noodle treatment performances using ECSBR and SBR systems were examined. In the first part, it was found that the cell loadings (0.6-2.7 9 10 8 cells/mL) did not play an important role in this study. Treatment reactions followed the second-order kinetics with the treatment efficiencies of 92-95%. In the second part, the result showed that ECSBR performed better than SBR in both treatment efficiency and system stability perspectives. ECSBR maintained glucose removal of 82.5 ± 10% for 5-cycle treatment while glucose removal by SBR declined from 96 to 40% within the 5-cycle treatment. Scanning electron microscopic images supported the treatment results. A number of yeast cells entrapped and attached onto the matrix grew in the entrapment matrix.

“…The use of AC for the treatment of this type of effluent becomes an interesting option for the removal of color and organic compounds (SHAWWA et al, 2001;MUHAMAD et al, 2011;HAQ et al, 2020). The physical and chemical properties of AC are crucial to determine its best application in the removal of target adsorbates.…”

A extração da lignina kraft (LK) do licor preto (LP) gerado no processo de polpação é uma opção atraente devido aos diversos produtos de alto valor agregado que podem ser obtidos deste material. A possível conversão de fábricas de polpa celulósicas em biorrefinarias diversificaria sua linha de produtos e aumentaria a capacidade de produção de polpa, ao diminuir a carga orgânica (lignina) enviada para a queima nas caldeiras de recuperação. A produção de carvão ativado (CA) a partir de LK é uma opção viável devido às boas características físico-químicas, ao alto volume e disponibilidade da matéria prima. O uso do CA no processo de produção de polpa celulósica kraft é amplo, sobretudo para o tratamento de águas e de efluentes. Na presente pesquisa o CA foi utilizado visando o tratamento setorial dos filtrados do branqueamento (remoção de Mn) e no tratamento terciário de efluentes para a remoção de fósforo e matéria orgânica (DQO). O CA produzido foi quimicamente ativado com NaOH e apresentou características físico-químicas e morfológicas adequadas, as quais foram determinadas através de análise elementar e imediata, análise de metais, capacidade de troca catiônica, ponto de carga zero, número de iodo, análise de microscopia eletrônica de varredura, espectroscopia na região infravermelho e difração de raio-X Adicionalmente foram feitos testes de cinética para conhecer o mecanismo de adsorção avaliando modelos de pseudo primeira e segunda ordem, difusão intrapartícula e Elovich. O equilíbrio de adsorção também foi avaliado, aplicando-se modelagem com as equações de isotermas de Langmuir e Freundlich. O adsorvente apresentou uma alta capacidade de remoção de fósforo e de matéria orgânica 88,1% e 52,8% respectivamente. Na remoção de Mn não foi evidenciada nenhuma remoção do elemento, pelo contrário foi liberado Mn na solução. Esta liberação do elemento está associada à alta concentração de metais (Mn) no CA e na LK. No entanto, o uso de CA para a remoção de Mn não deveria ser descartado. O CA a partir de LK foi eficiente no tratamento terciário para a remoção de fósforo e de matéria orgânica recalcitrante, permitindo uma melhora da qualidade do efluente final.
