MAST Wastewater Treatment System

MAST (Microbe Algae Sewage Treatment) technology is used in the treatment of municipal wastewater consisting of sewage as well as industrial effluent wastewater. The way the technology is designed is very simple. After assessing the microbes in the wastewater, a selection of algal species is made to effectively treat the wastewater. There is a symbiotic relationship between the microalgae and microbes. The way the system works is that microbes require oxygen, this is provided by the algae species in the form of supersaturated oxygen of 350%. In turn the algae get carbon dioxide for growth from the microbes that die in the process.

Besides this the microalgae gets additional carbon dioxide from the atmosphere, thus making the system carbon negative. MAST works due to the presence of sunlight, carbon dioxide and nutrients.
