“…The nutrient content of kitchen wastewater can be utilized for reuse in agricultural sector if it can be treated using an ecofriendly, sustainable and low cost technique like phytoremediation. In recent years, the artificial constructed wetland with floating aquatic plant species such as water hyacinth [4], water lettuce [5], duck weed [6], vetiver grass [7] have been used for treatment of wastewater. Eichhornia crassipes has been considered as problematic aquatic free floating weed because of its uncontrolled growth in water bodies and it is difficult to control and eradicate this plant from water bodies.…”

Abstract. The efficiency of Eichhornia crassipes for treatment of raw kitchen wastewater was studied in the present research work. An artificial wetland of 30 liter capacity was created for phytoremediation of kitchen wastewater using Eichhornia crassipes. Kitchen wastewater samples were collected from hostel of an educational institute in India. Samples were characterized based on physical and chemical parameters such as pH, turbidity, total hardness, nitrate-nitrogen, ammonium-nitrogen, sulphate, dissolved oxygen, total organic carbon and total dissolved solid. The physico-chemical parameter of kitchen wastewater samples were analysed for durations of 0 (initial day), 4 and 8 days. After 8 days of retention period, it was observed that pH value increases from 6.25 to 6.63. However, percentage reduction for turbidity, total hardness, nitratenitrogen, ammonium-nitrogen, sulphate, dissolved oxygen, total organic carbon and total dissolved solid were found to be 74.71%, 50%, 78.75%, 60.28%, 25.31%, 33.33%, 15.38% and 69.97%, respectively. Hence water hyacinth (Eichhornia crassipes) is found efficient and easy to handle and it can be used for low cost phytoremediation technique.

“…However, natural wetland-systems are usually cheaper to build and maintain [46,47]. In our case, the cost of the wetland system was about 131,050 euros, and provides additional purification of wastewater effluent released by a wastewater treatment plant before entering a protected Ramsar wetland.…”

This work concerns the case study of a Mediterranean Ramsar salt lake (Fuente de Piedra, southern Spain) that receives the treated wastewater of the local village treatment plant. The wastewater goes through a system of canals, water dams, and three semi-natural ponds that were built in 2005. This work aims to investigate the capacity of the system to assimilate the impact of wastewater effluents on Lake Fuente de Piedra. For this, four points were sampled on 27-29 April 2016, at the inlet and the outlet points of the first and the third semi-natural ponds, with three replicates each. Temperature, pH, and conductivity at the inlet were 19.62 • C, 7.99, and 3262.67 µS/cm, respectively, and increased through the pond system by 7.59%, 8.04%, and 37.34%, respectively. Phytoplankton concentration indicators decreased from the inlet point to the outlet point (chlorophyll a from >500 to <20mg/L), as did the biovolume (from >5 × 10 10 to 4.3 × 10 9 µm 3 /mL). Zooplankton biovolume, in contrast, increased three orders of magnitude from the inlet (3.5 × 10 7 µm 3 /mL) to the outlet point (1.6 × 10 9 µm 3 /mL). Heterotrophic bacteria (1.29 × 10 5 cfu/mL) and faecal enterococci (1033 ± 351 cfu/100 mL) were high at the inlet point, but decreased at the outlet point by almost three orders of magnitude. Total phosphorous and total nitrogen decreased 40.3% and 23.1% through the pond system. The results showed an improvement in water quality in its passage through the built system. Additionally, as permanent wetlands with acceptable water quality, the water system attracts wild fauna during the dry summer, leading to the conclusion that these semi-natural or artificial wetlands should be extrapolated to other aquatic ecosystems (Mediterranean wetlands) that receive contributions of residual waters. Better functioning of the treatment plant is desirable to improve the conservation of the Ramsar and adjacent wetlands systems.

“…Constructed wetland systems for wastewater treatment can be land-intensive, according to some estimates: a system for wastewater from 10,000 persons requires twenty acres of land [35]. However, recent advances in wastewater treatment methods such as using "biohedge" matrices to grow decomposing microbes can reduce land-intensiveness of such treatment systems [36]. Biochar, a byproduct of agricultural biomass waste, was found by researchers at Kwandong University in Korea to greatly enhance constructed wetland function due to its highly porous structure and low economic investment.…”

Wastewater treatment systems in urban areas of the United States have reached a critical replacement age. From century-old, deteriorating systems raw sewage overflows into basements, streets and surface waters. In economically depressed cities, sewage overflows are frequent and heavily fined, costing municipalities millions of dollars. Pollution by untreated wastewater severely degrades aquatic and wetland ecosystems and exacerbates serious risks to public health. Necessary and extensive clean water infrastructure repairs are imperative to protect the health and habitat of humans and other organisms. As accelerating human development contributes to wide spread losses of naturally occurring wetlands, dwindling patches of habitat native plant and animal species rely on for survival are further threatened. Within this alarming situation is an opportunity to rebuild and retrofit our wastewater treatment systems with infrastructure that enhances long-term ecosystem sustainability.
