Water hyacinth (Eichhornia crassipes), duckweed (Spirodela sp. andLemna sp.), water pennywort (Hydrocotyle ranunculoides), and kudzu (Pueraria lobata) were anaerobically fermented using an anaerobic filter technique that reduced the total digestion time from 90 d to an average of 23 d and produced 0.14-0.22 m3 CH4/kg (dry weight) (2.3-3.6 ft3/lb) from mature filters for the 3 aquatic species. Kudzu required an average digestion time of 33 d and produced an average of 0.21 m3 CH4/kg (dry weight… 
Hybrid wastewater treatment system using anaerobic microorganisms and reed (Phragmites communis)
Data demonstrated that by combining anaerobic filters, also referred to as attached film filters, and vascular aquatic plants a synergistic effect is produced which increases the treatment efficiency of each individual system.
Mass Production of Lemna minor and Its Amino Acid and Fatty Acid Profiles
The surface floating duckweed Lemna minor (Lemnaceae) is a potential ingredient to replace the application of fish-meal in the aqua-feed and its nutritional value and their production potential in the pond conditions were evaluated.
Soil-Less Use of Aquatic Macrophytes in Wastewater Treatment and the Novel SHEFROL ® Bioreactor
Hydroponics, a Greek word which literally means ‘water working’, represents horticulture without the use of soil. It has been attempted since thousands of years and descriptions are available of
Differential responses ofAzolla microphylla Kaulf andAzolla filiculoides Lam. to lead nitrate
Lead nitrate in nutrient media was used to assess the tolerance/response of two Azolla microphylla and Azolla filiculoides to heavy metals, finding that Amicrophylla was more tolerant of the higher concentrations of lead nitrate, whereas A. filiculides had a higher rate of lead uptake.
Separated Hydrolysis and Fermentation of Water Hyacinth Leaves for Ethanol Production
In this study, the acid pretreatment and enzymatic hydrolysis were used to evaluate to produce more sugar, to be fermented to ethanol. Separated hydrolysis and fermentation (SHF) studies were carried
Phyto Remediation of Waste Water Through Aquatic Plants for the Change Detection Analysis in the Chemical Properties Within the District Dhanbad,Jharkhand
The paper briefly describes the importance of algae, vetiver grass, hydrilla and water hyacinth (Aquatic plant) in the phytoremediation of coal mine and municipal wastewater bio-purifications. A
Waste Water Management through Aquatic Macrophytes
Various wastewater treatment technologies are being used depending on various factors ranging from their availability, suitability and cost effectiveness to the local conditions. Many of the
Adsorption of Congo red and crystal violet dyes onto cellulose extracted from Egyptian water hyacinth
The present investigation has highlighted the utility of floating aquatic Egyptian hyacinth, which is considered as a significant reason for environmental problems in Nile River, to offer an

Global water depletion and unsustainable food production systems represent two iconic crises of our time. These two crises have important themes in common, referring to basic human needs and the way


Bio-conversion of water hyacinths into methane gas. Part 1. [Effects of cadmium and nickel pollution]
Bio-gas and methane production from the microbial anaerobic decomposition of water hyacinths (Eichhornia crassipes) (Mart) Solms was investigated. These experiments demonstrated the ability of water
Water hyacinth (eichhornia crassipes) productivity and harvesting studies
Water hyacinth growth rates were monitored from May through October in two sewage lagoons with different nutrient loading rates. The lagoon receiving the heaviest load sustained the highest average
Comparative Study of Wastewater Lagoon with and without Water Hyacinth
A 3-year study was conducted on an existing, one-cell, facultative sewage lagoon having a total surface area of 3.6 ha and receiving a BOD5 loading rate of 44 kglhald (40 Iblald). The comparative
Energy conservation and scale-up studies for a wastewater treatment system based on a fixed-film, anaerobic bioreactor
Oak Ridge National Laboratory (ORNL) is developing an energy-conserving wastewater treatment system based on a fixed-film anaerobic bioreactor. The treatment process is based on passing wastewaters
The anaerobic filter for waste treatment.
An entirely new anaerobic treatment process has been found to be particu larly effective for the treatment of low strength soluble organic wastes. This process, termed the "anaerobic filter," is
