Micro algae culturing device

An automatic algae culturing system, comprising:

• at least one optically transparent photosynthesis tubular reactor for carrying out algae culturing by feeding an algae culture medium into the tubular reactor, where walls of the tubular reactor are transparent to avoid blocking of sunlight and coated with a superhydrophobic coating to avoid formation of a biofilm;
• cleaning particles coated with cationic silica nano particles (CNP) to scrape off unwanted particles including at least a biofilm, bio dust, wherein the cleaning particles are being run within the tubular reactor with flow of water or a liquid into the tubular reactor to scrape off biofilm;
• a dewatering device connected with the tubular reactor for harvesting cultured algae from the tubular reactor and for isolation of biomass from the cultured algae;
• and
• a nano-air bubble generating device installed around the tubular reactor to generate and feed nano-air bubbles into the tubular reactor,
• where the nano-air bubbles inside the tubular reactor increase an active surface area for one or more ions to interact with the algae in the culture medium in order to increase productivity of the automatic algae culturing system by enhancing one or more activities, including rate of mitosis, productively of oil, protein and polysaccharide;
• and wherein the nano-air bubbles inside the tubular reactor sterilizes the culture medium;
• and
• wherein the automatic algae culturing system operates in close system in order to prevent cross contamination and ecosystem diversification from initial culturing in the tubular reactor to harvesting with the dewatering device, and wherein the automatic algae culturing system is self cleaning system due to the CNP coated cleaning particles.
