Abstract
Embodiments of the present invention provide an automatic micro algae culturing device and system for self-cleaning, continual automatic algae culturing and irradiant optimizing. The culturing device includes a photosynthesis tubular reactor for micro algae culturing, with transparent cleaning particles to scrape off any unwanted particles or components such as including and not limited to formation of biofilm. The tubular reactor has multiple double-walled glasses. Inner walls of the tubes in the tubular reactor may be coated with superhydrophobic coating to avoid bio film formation, or sticking of any hydro dirt or dust particles. Because the cleaning particles are transparent, they wont block any sunlight for photosynthesis in the tubular reactor.
Claims18
An automatic algae culturing system comprising:
- at least one optically transparent photosynthesis tubular reactor for carrying out algae culturing, 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, and
- wherein the walls of the tubular reactor are made of transparent material, including at least one or both of bismuth silicate glasses or polymethyl methacrylate (PMMA), and wherein the superhydrophobic coating is at least of polydimethylsiloxane (PDMS)/poly(methyl methacrylate)PMMA solution;
- cleaning particles coated with cationic silica nano particles (CNP) to scrape off unwanted particles including a biofilm, where the cleaning particles are being run within the tubular reactor with flow of water or liquid into the tubular reactor to scrape off biofilm;
- a plurality of LED lights installed around the tubular reactor for providing LED light to carry out the algae culturing during night;
- a plurality of computer controlled solar panels, installed around the tubular reactor, for harvesting the solar energy during day, and providing electrical energy to power the plurality of LED lights during the night;
- and
- 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
- 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, and
- wherein the automatic algae culturing system operates for 24 hours culturing algae using sunlight during day, and using the LED light during night.
An automatic algae culturing system comprising:
- an algae culturing reservoir for providing algae to a tubular reactor;
- at least one optically transparent photosynthesis tubular reactor, in connection with the algae culturing reservoir, for carrying out algae culturing, where walls of the tubular reactor are transparent to avoid blocking of sunlight and coated with a superhydrophobic coating to avoid formation of a bio film;
- cleaning particles coated with cationic silica nano particles (CNP) to scrape off unwanted particles including a biofilm, where the cleaning particles are being run within the tubular reactor with flow of water or liquid into the tubular reactor to scrape off biofilm;
- a plurality of LED lights installed around the tubular reactor for providing LED light to carry out the algae culturing during night;
- a plurality of computer controlled solar panels, installed around the tubular reactor, for harvesting the solar energy during day, and providing electrical energy to power the plurality of LED lights during the night;
- a set of mirrors, installed around the tubular reactor, for directing the sunlight towards the tubular reactor for improving photosynthesis;
- and
- 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
- 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, and
- wherein the automatic algae culturing system operates for 24 hours culturing algae using sunlight during day, and using the LED light during night.
