An algae based wastewater treatment technology for less CO2 emissions


The main problems in the Waste Water Treatment Plants nowadays are connected to the sludge management and sludge disposal, due to the waste’s harsh chemical content, incorporated into the sludge through the chemical treatment. Our technology is offering a unique solution to these problems. Through Microalgae biological treatment and BioChar filtration we are eliminating the need of any chemical additives, which results in a final sludge product that is totally reusable as a fertilizer in the agriculture and is also a source of a high quality biogas.
