The purpose of this study is evaluating a new water treatment technology; electrochemical technique and see if the technique is an alternative for municipal wastewater treatment. The aim of the project was also to test the electroflotation by purification of phosphorus from synthetic wastewater and separation of green algae from the culture medium so the technology can be evaluated. To answer the purpose, two different experiments were made at laboratory. In the first experiment, wastewater was purified from phosphorus with electroflotation. In the second experiment, green algae were separated with the same technology, but with different machine. The results of the study show that the electrochemical technology is a good technique to separate green algae from the culture medium. In the tests the removal efficiency was over 90 %. Results from the phosphorus purification did not go so well, because sources of error in the system. To summarize the results of the project the electrochemical technology is a good alternative to other wastewater treatments because it’s more environmental friendly and easy to operate.
