A Modified Aeration Process for Promoting Nutrient Removal Using Water Hyacinth to Treat Sewage
To upgrade some conventional aeration processes, a lab-scale system for promoting nitrogen and phosphorus removals was set up and studied through a series of experiments, in which water hyacinth was planted on the surface of the mixed liquor in aeration tanks. The main purpose of this study was to evaluate the effects of (1) aeration, (2) organic load (chemical oxygen demand) and (3) residence ...
متن کاملRemoval of Heavy Metals from Waste Water Using Water Hyacinth
-Water pollution has become one of the most serious problems of today’s civilization. In the last few years considerable amount of research has been done on the potential of aquatic macrophytes for pollutant removal or even as bio-indicators for heavy metals in aquatic ecosystems. Water hyacinth is one of the aquatic plant species successfully used for wastewater treatment. It is very efficient...
متن کاملStudies on removal of Zinc and Chromium from aqueous solutions using water Hyacinth
Phytoremediation is an eco-friendly method for removal of pollutants, which can be relied upon as a sustainable technology, if implemented under optimum conditions of plant growth. The effectiveness of water hyacinth, a topical weed, for the removal of Zinc (Zn) and Chromium (Cr) ions from aqueous solutions has been presented in this article. The potential of this plant in removing metals by ph...
متن کاملRemoval of Cadmium and Zinc by Water Hyacinth, Eichhornia crassipes
Toxic heavy metal pollution of water and soil is a major environmental problem, and most conventional remediation approaches do not provide acceptable solutions. Wetland plants are being used successfully for the phytoremediation of trace elements in natural and constructed wetlands. This study demonstrates the phytoremediation potential of water hyacinth Eichhornia crassipes, for the removal o...
متن کاملAeration of anaerobically digested sewage sludge for COD and nitrogen removal: optimization at large-scale.
The paper will report about the experiences at an Austrian large wastewater treatment plant of 720,000 population equivalents, where anaerobically digested sewage sludge is further stabilised under aerobic conditions. Enhanced stabilisation of the anaerobically digested sludge was required at the plant in order to get a permit for landfill disposal of the dewatered stabilized sludge. By impleme...
