The objective of the study was to evaluate the performance of three different aquatic macrophytes for treatment of municipal wastewater collected from Taxila (Pakistan). A physical model of treatment plant was constructed and was operated for six experimental runs with each species of macrophyte. Every experimental run consist of thirty days period. Regular monitoring of influent and effluent c...

Rawa Pening Lake has been in critical condition, caused by high sedimentation levels, declining water quality, damage to the watershed, and excessive riparian occupation. Therefore, this study aims identify main problems of revitalization lake. Data information collection were carried out through direct observation interviews. The results showed that lake removal weeds/water hyacinths, tidal ri...

The biotemplating technique is an environmental-protective high-efficiency new technology by which the resulting TiO2 may simultaneously attain the duplication of structure and self-doping elements from biotemplate materials, which is highly desirable for photocatalytic applications. In this paper, aquatic plant leaves—including reed, water hyacinth, and duckweed—were used as both templates and...

In recent years, the disposal of organic wastes from domestic, agricultural and industrial sources has caused increasing environmental concerns. In this regard, the recycling of utilizable waste is feasible. This can be solved by combination of effective technologies like Biodung composting and Vermitech (incorporating earthworms for the production of vermicompost). The present work was carried...

The potential use of water hyacinth dry matter for removing heavy metals from wastewater is studied by combining various spectroscopic techniques and quantum chemical ab initio calculations. The aquatic plant water hyacinth was treated with 0.025, 0.050, 0.100, 0.200, and 0.400 M acetic acid for different times up to 19.0 hours. The plant was divided into root and shoot then dried and grinded i...

Animal manure and water hyacinth will become waste in the environment if not utilized. One form of utilization both is to make it as raw material for biogas. The aims this study were: determine effect type on process forming biogas from hyacinth, which related to: 1) speed formation, 2) temperature slurry , 3) pH 4) volume produced. This was designed with a completely randomized design (CRD), c...

The phytoremediation potential of water hyacinth, Eichhornia crassipes (Mart.) Solms, was examined in two independent studies under nitrogen (N) rates of 0, 40, 80, 100, 150, 200, and 300 ppm. A modified Hoagland solution was added to ponds containing water hyacinths which were rated and measured weekly for 4 weeks. The hyacinths accounted for 60–85% of the N removed from solution. Net producti...

Water hyacinth (Eichhornia crassipes [Mart.] Solms) plants were grown in environmental chambers at ambient and enriched CO(2) levels (330 and 600 microliters CO(2) per liter). Daughter plants (ramets) produced in the enriched CO(2) gained 39% greater dry weight than those at ambient CO(2), but the original mother plants did not. The CO(2) enrichment increased the number of leaves per ramet and ...

The wastewater at Sukinda chromite mines (SCM) area of Orissa (India) showed high levels of toxic hexavalent chromium (Cr VI). Wastewater from chromium-contaminated mines exhibit potential threats for biotic community in the vicinity. The aim of the present investigation is to develop a suitable phytoremediation technology for the effective removal of toxic hexavalent chromium from mines wastew...
