The reuse of treated agricultural wastewater is a need that has many interests, both on environmental plans. In recent years a rise problem in the pollution, this is the poor
Caulerpa lentillifera are photosynthetic microorganism which use energy from the sun to grow, consuming inorganic nutrients and CO2. These Cyanobacteria require higher amount of nutrients (N, P) for their growth, agricultural wastewater rich in nutrients can be used as growth medium for their cultivation and indirectly they sequester these nutrients from agricultural wastewater. Caulerpa lentillifera not only treatment BOD and removal of nutrients (N, P) from the agricultural wastewater, but can also be captured returned to the terrestrial environment. The technology of using Caulerpa lentillifera in agricultural wastewater is based on natural ecosystem, there isn’t danger for environment.
