Artificial wetlands and floating islands: Use of macrophytes

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, since allow their filtration, retention absorption, among other processes. The objective work has been to show diversity emergent aquatic used treatment, highlighting such as Typha latifolia, doingness Eichhornia crassipes, constant use. In efficiency, manage nutrients organic matter excess, well toxic elements zinc, cadmium, lead, chromium, mercury, others, values between 15-95%. Some studies also address emerging pollutants, showing successfully mitigate presence contamination by these micro-pollutants, eliminating paracetamol, ibuprofen, caffeine antibiotics, 75-99%. frequent management practice mitigation biomass generated issue little explored rarely considered. It highlight several works where feed animals, fertilizers, generate building blocks production bioenergy through biogas.
