Phycoremediation of effluents
It is a sub-type of bioremediation in which macroalgae or microalgae are used to remove or
Biotransforming pollutants, including nutrients and xenobiotics in water
Black and CO2 from superfluous air.
They are a group of aquatic photosynthetic organisms, primitive, evolutionarily found in the
Limits of the passage from unicellular life forms to pluricellular, and usually possess chlorophyll,
But it lacks true roots and stems.
Ecological and safe
Microalgae are organisms that are found naturally in the environment, so in fact, ficoremediation is a phenomenon that occurs naturally. The microalgae used in fiction media are natural in the environment, from which they subtract various hazardous materials, and although we come in contact with them daily, they do not produce deleterious effects. After executing a fictionemediation protocol, the environmental balance is returned practically to the original one.

Methods of execution
According to the needs of each case, it can be operated with swimming pools, semi-continuous flow or continuous flow.
Types of Effluents
This technology is flexible, can tolerate fluctuations in the quality and quantity of the effluent. In addition, its effectiveness has been proven to process effluents from the textile, dye, food, chemical, oil drilling, dairy and oil industry
After processing, it is not necessary to separate the algae from the treated effluent as it is ecologically safe and natural. However, when you want to do so, you can take advantage of the easy sedimentation that is typical of algae. The filamentous microalgae also has high capacity of autoflocculation.
This technology is highly compatible with others already existing as physical, chemical and other biological methods, being able in many cases to integrate them.
Phycoremediation minimizes the need for automation, maintenance and qualified operation.
Phycoremediation ensures zero sludge generation, thereby avoiding contamination of surrounding areas.
It is only necessary to add nutrients to the medium during the beginning of the cultivation process. Once the process has reached its critical momentum, it is not necessary to add any additional input. In addition, the cost of these chemicals is virtually insignificant.
Thanks to the rapid rate of multiplication of microalgae, only one initial inoculum is used. The populations are reestablished with the addition of fresh effluent.
Odorless and colorless
Microalgae are experts in deodorizing and discoloring effluents
Phycoremediation is cost effective as it saves energy, and avoids the use of many chemicals. Usually, it is between 20-30% less expensive than other chemical and mechanical alternatives. In addition, the initial investment in capital and equipment is small. The only energy requirement of the process is the availability of solar energy, which is available in abundance in our latitudes.
