“…The study reported that there was a total reduction of 42% of tannin and lignin using the CW planted with a cattail ( Typha sp.). This is in agreement with Grismer and Sherpherd 36 who reported successful reduction of up to 77.9% of tannin and lignin from the winery process wastewater by subsurface flow wetland. Comparing both studies with this study, better removal of tannin and lignin was achieved on day 52 to day 75 of 82.9 ± 0.47%, which is higher than reported literature 36 , 37 .…”

“…Overall, the removal of tannin and lignin was 57.5 ± 22.3% using this CW, and believed to be related to the loading rates and hydraulic retention time (HRT). According to Grismer and Sherpherd 36 , a smaller loading rate and greater HRT can influence the removal efficiency to reach nearly 100% provided that the recirculation system of effluent is applied. It was reported that CW have been proven to have the ability to reduce the concentration of tannin and lignin in wood waste leachate 37 .…”
The reason for such enormous efforts in palm oil mill effluent research would be what has been singled out as one of the major sources of pollution in Malaysia, and perhaps the most costly and complex waste to manage. Palm oil mill final discharge, which is the treated effluent, will usually be discharged to nearby land or river since it has been the least costly way to dispose of. Irrefutably, the quality level of the treated effluent does not always satisfy the surface water quality in conformity to physicochemical characteristics. To work on improving the treated effluent quality, a vertical surface-flow constructed wetland system was designed with Pennisetum purpureum (Napier grass) planted on the wetland floor. The system effectively reduced the level of chemical oxygen demand by 62.2 ± 14.3%, total suspended solid by 88.1 ± 13.3%, ammonia by 62.3 ± 24.8%, colour by 66.6 ± 13.19%, and tannin and lignin by 57.5 ± 22.3%. Heat map depicted bacterial diversity and relative abundance in life stages from the wetland soil, whereby bacterial community associated with the pollutant removal was found to be from the families Anaerolineaceae and Nitrosomonadaceae, and phyla Cyanobacteria and Acidobacteria.

“…However, in general, direct comparison experiments between planted and unplanted CW give results similar to the present work-planted CWs performed better than unplanted CWs [32,[46][47][48][49]. Among the possible roles of plants in the wastewater treatment processes, the roots surface support for microbial film development and the provided oxidized rhizosphere were pointed out as the principal plants contributions [37,42,50,51].…”
This research was conducted to evaluate the feasibility of using the bioenergy crop Saccharum officinarum (sugarcane) as vegetation and mineral wastes for filling in constructed wetlands (CWs) designed for the removal of nutrients from wastewater. Four horizontal subsurface flow pilot-scale CWs were monitored during one year: two filled with fragmented limestone and two with clay brick fragments, two planted and two unplanted controls. Sugarcane stalk height, diameter and foliar area were evaluated during the plant-cane cycle along with total phosphorus (TP) and total nitrogen (TN) removal efficiencies from the wastewater. Sugarcane biomass production was 107 ton/ha for the brick fragments filled CW and 67 ton/ha for the fragmented limestone filled CW. Planted CWs show better nutrient removal efficiencies than the unplanted. Planted CW filled with brick fragments show average efficiencies of 77%˘4% for TP and 60%˘12% for TN, and planted CW filled with fragmented limestone 68%˘3% for TP and 58%˘7% for TN. Results showed that the use of sugarcane as CW vegetation is a viable alternative to produce a bioethanol raw-material without the use of arable land and irrigation water, while it maintains the wastewater treatment capabilities of CWs.

The objective of this study is to show the potential of Typha latifolia in the Purification performance of wastewater in the region of El Oued (southeast of Algeria). The pilot scale consists of two beds of plastics, filled with gravel and sand. One was planted saplings Typha latifolia at 36 stems/m 2 , the second was not planted serves as a control (witness). The results show good yields for suspended solids and organic pollution, removal rates are 96,76% for (SS) 89,92% for the Chemical Oxygen Demand (COD) and 87, 98% for biochemical oxygen demand in 5 days (BOD 5 ). There is a clear increase in the concentration of dissolved oxygen (DO). The system effectively removes nitrite (88.84%), nitrate (91.20%), and orthophosphate (93.12%).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
