Abstract Floating bed (FB) is one of the low cost and efficient system to treat polluted water bodies in rural as well urban area. It requires less space compared other macrophyte based treatment system. Vegetation coverage an effective factor atmospheric oxygen diffusion body depends upon this. When a fully covered by vegetation, it prevents oxygen, which major source dissolved (DO). An optimu...

An innovative methodology was implemented for removing arsenic from aqueous solution by developing successive biosorption experiments. Considering the high affinity of As oxyanions toward Fe(III) oxides, Fe(II) first conducted using nine biomaterials—aquatic and terrestrial invasive species, biowastes, local plants. Pistia stratiotes, an alien species presenting highest concentration adsorbed F...

Abstract This study evaluated the concentrations and distributions of nutrient non-nutrient elements in water, sediment, mud, vegetation Ologe Lagoon, Lagos, Nigeria. Nutrient including Na, Ca, K, Mg were found high concentration values different components freshwater ecosystem. While water had least elements, Trapa natans highest. Aluminium showed similar distribution patterns components, exce...

A detailed study was carried out in Jannapura tank near Bhadravathi town of Shimoga district on physico-chemical parameters, fish diversity, aquatic macrophytes and Plankton composition during January to December 2008. The results of physico-chemical parameters were compared with Bureau of India Standards (BIS) and World Health Organization (WHO) standards. The study revealed that, tank water i...

The aim of the study was to determine the changes in suspension particle size identified in biologically treated wastewater, which was then treated in hydroponic system with use of engineering lighting by the light-emitting diodes (LED). The study was subjected to wastewater purified under laboratory conditions, in a hydroponic system using the effect of macrophytes Pistia stratiotes and growin...

Phytoremediation, a plant based green technology, has received increasing attention after the discovery of hyperaccumulating plants which are able to accumulate, translocate, and concentrate high amount of certain toxic elements in their above-ground/harvestable parts. Phytoremediation includes several processes namely, phytoextraction, phytodegradation, rhizofiltration, phytostabilization and ...
