“…Moreover, the untreated distillery effluents from the distilleries is often characterized by a high organic load with 5-d biological oxygen demand (BOD 5 ) and chemical oxygen demand (COD) levels that range from 35,000 mg/L to 60,000 mg/L and 60,000 mg/L to 120,000 mg/L, respectively (Billore et al, 2001). Furthermore, wastewater generated from milk processing and cleaning also has high concentrations of COD (from 1200 mg/L to 5300 mg/L), and O&G (from 150 mg/L to 1800 mg/L) (Danalewich et al, 1998;Travis et al, 2012).…”

“…Oil & grease with concentrations ranging from 150 mg/L to 1800 mg/L often generated from milk processing and cleaning (Danalewich et al, 1998;Travis et al, 2012). The oils in wastewater are typically present in colloidal-sized emulsion droplets.…”

“…Treatment through porous media in CWs may result in high removal performance, but mainly relies on physical attachment to media surfaces (Imfeld et al, 2009). Moreover, slow biological degradation or even unavailability of oil can potentially lead to accumulation, development of hydrophobicity, and subsequent clogging in the treatment bed (Travis et al, 2012).…”

“…Natural treatment systems such as CWs have often accordingly been considered for post-treatment of these effluents because of their low maintenance and operating costs, tolerance to variable flows and organic loadings, and capacity to neutralize low pH (Serrano et al, 2011;de la Varga et al, 2013). Travis et al (2012) developed and tested a combined anaerobic digestion and VF CW system for on-site treatment of concentrated, oil-rich dairy farm wastewater. The anaerobic treatment mainly aimed to trap O&G, remove solids, and reduce the physicochemical variability of wastewater that enters the VF CW.…”

“…The comparatively high removal rate of the comparison system (b) shows that the removal efficiency of constructed wetlands with a variety of substrates configurations are less affected by the influent pollution load, own to the synergistic effect among various substrates [11]. Some research results [12][13][14][15][16] show that the removal rates of NH4 + -N and TN are 57%~71% and 50%~75% in composite constructed wetland, respectively. Relative to the original system (a), the removal effect is relatively stable but the average removal rate is lower, the removal rate of the original system (a) is not stable may be related to the single configuration of the substrates.…”

Abstract. In this study, a new coupling system of biological filter bed and subsurface-flow constructed wetland based on the self-ventilation network was proposed, and the comparative pollutant removal efficiency at low and high influent concentration of the pilot coupling system with different substrates configurations were investigated. The study found that: The comparison system (b) had better removal rates than that of the original system (a), and the removal rate when treating low influent concentration was 74.10%, 94.14%, 73.57% and 69.53%, while in high influent concentration case was 81.30%, 90.28%, 88.57% and 75.36% for CODCr, NH4 + -N, TN and TP, respectively. The removal of the above main water indexes of the comparison system (b) promoted by 11.00%, 11.55%, 2.69% and 8.09% respectively in low influent concentration case and 4.20%, 9.20%, 7.66% and 13.61% respectively in high influent concentration case when comparing to the original system (a), which showed that the optimized configuration of various kinds of substrates was significant and was more beneficial to the degradation and removal of pollutants. The adsorption and interception function of substrates in the constructed wetland was the main way of phosphorus removal. The function of self-ventilation ensured the amount of DO in the coupling system, making the phosphorus removal was less affected comparing to structure of traditional wetland.

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.
