“…Desde então, o vermifiltro tornou-se uma alternativa de tratamento de efluentes sanitários, tanto para o tratamento de esgotos domésticos (SINHA et al 2008;LIU et al 2013;NIE et al 2014) como para águas cinzas (ADUGNA et al 2019) e águas de vaso sanitário (FURLONG et al, 2015). Sua construção e operação simplificadas viabilizam sua aplicação em sistemas descentralizados, podendo ser dimensionado para unidades unifamiliares ou para estações semicoletivas .…”

“…O estudo do processo da vermifiltração ainda é pouco expressivo na literatura brasileira (SARTO-RI, 2010;MADRID, 2016), mas ela tem sido amplamente estudada na Austrália (TAYLOR et al 2003;HUGHES et al 2008;SINHA et al 2008), na China (XING et al 2010;LIU et al 2013;NIE et al 2014) e na Índia (KUMAR et al 2014;ARORA et al 2014;FURLONG et al 2015).…”

“…Todos esses estudos investigaram o potencial da aplicação da vermifiltração em sistemas descentralizados de tratamento de esgotos sanitários, destacando-se Liu et al (2013) e Nie et al (2014) por relatarem o desempenho da tecnologia em escala plena no tratamento de efluentes domésticos de vilas rurais na China. A Tabela 1 reúne as informações básicas das principais pesquisas internacionais e das poucas nacionais sobre a vermifiltração aplicada no tratamento de esgoto sanitário.…”

“…Até o momento, as principais composições empregadas para o substrato da camada superficial com minhocas foram: serragem misturada a outros agregados (SOTO; TOHÁ, 1998;LI et al, 2009;SARTORI, 2010;NIE et al, 2014), agregados sem a mistura de outros componentes (XING et al, 2010;LIU et al, 2013) e solo puro (SINHA et al, 2008;MADRID, 2016). Contudo, há pouco detalhamento de todos os componentes utilizados em cada substrato sem a especificação dos respectivos tamanhos das partículas e proporções de mistura, tendo alguns autores indicado somente o uso de uma camada de "húmus" ou "vermicomposto" (SOTO; TOHÁ, 1998;TAYLOR et al, 2003;KUMAR et al, 2014;ARORA et al, 2014;LOURENÇO;NUNES, 2017).…”

“…Cada vermifiltro possuía uma válvula dosadora controlada por um controlador lógico programável (Figura 2), permitindo uma programação de aplicação de afluente bruto de maneira individualizada. Nie et al (2014), adotou-se uma densidade inicial de anelídeos de 12,5 kg de organismos para cada m 3 de substrato da camada de serragem. Considerando que o peso médio de uma minhoca adulta é de 0,5 g (DOMINGUEZ e EDWARDS, 2011), essa densidade é equivalente à 25.000 organismos.m -3 de substrato.…”

The vermifiltration (VF) technology has gained significant attention as a green alternative for remediating domestic and industrial wastewater over the last few decades. Of late, the implementation of various modifications to the orthodox VF technology, including tweaks in the design and operation of the vermifilters, has been portrayed in the available literature. However, owing to the scatteredness of the available information, the knowledge regarding the execution of the modified vermifilters is still inadequate. Hence, an effort has been made to comprehensively overview the innovative strategies and techniques adopted to improve the organic and nutrient removal potential of the VFs from wastewater. In addition, future perspectives have been recognized to design more efficient and sustainable VFs. This review explores more of such novel tactics to improve the performance of the VF technology regarding organic and nutrient removal from wastewater. Practitioner Points Innovative strategies and techniques implemented to VF technology were comprehensively overviewed. Design modification and advantages of each innovation were highlighted. The pollutant removal performance of every modification was emphasized. Modified vermifilters were better than the conventional vermifilters in terms of organic and nutrient removal from the wastewater.

Effects of total vermibed depth, as well as the ratio of aerobic (the unsubmerged) to anaerobic (the submerged) zone on the performance of the horizontal subsurface flow macrophyte‐assisted vermifilters (HSSF‐MAVFs) treating synthetic brewery wastewater at a higher hydraulic loading rate (HLR), were investigated for the first time. Results showed that the HSSF‐MAVF with a 50 cm total and 18 cm submerged vermibed depth yielded the optimum removal of the pollutants, ensuring a (91.2 ± 1.7)%, (81.8 ± 1.9)%, (67.4 ± 3.9)%, and (63.1 ± 2.3)% removal of chemical oxygen demand (COD), ammonium N (NH4+–N), total N (TN), and organic N, respectively, whereas there was an increase of (142 ± 6.3)% in the effluent nitrate–N (NO3−–N) than that in the influent. At the optimum condition, the effluent concentrations of all the pollutants including COD, NH4+–N, NO3−–N, TN, and organic N were well below the surface water discharge standards specified by the Central Pollution Control Board (CPCB), and thus, the effluent of the HSSF‐MAVF could be safely discharged into the surface water bodies.Practitioner Points Total vermibed depth of HSSF‐MAVFs was optimized for organic and nitrogen removal. HSSF‐MAVFs were subjected to the higher HLR of synthetic brewery wastewater. Removal of COD and NH4+–N was decreased with the increase in submerged bed depth. Removal of organic N and TN was increased with the increase in submerged bed depth. Total/unsubmerged bed depth had a positive impact on the organic and N removal.
