Constructed wetlands, including floating islands, are a suitable technology for wastewater treatment. They low cost and respectful with the environment, which is why they significantly beneficial agricultural irrigation systems. One of limiting factors in structuring efficient constructed wetlands choice plant species that can tolerate eliminate contaminants. Macrophytes have an important role,...

Potential use of retention/detention reservoirs stocked with vascular aquatic macrophytes was evaluated, using a microcosm reservoir for reducing the N and P levels of agricultural drainage effluents (waste water). The treatments evaluated were reservoirs stocked with (i) pennywort (Hydrocotyle umbellata L.), (ii) water hyacinth (Eichhornia crassipes [Mart] Solms), (iii) cattails (Typha latifol...
