Pure algae growth system and method

A continuous growth system for inclusion and/or growth of algae with an in-situ cleaning functionality, the system comprising:

• (a) a central distribution tank comprising a temperature controlling jacket and acting as a central process control location, wherein growth and process variables are controlled, micronutrients supply, nitrogen and phosphorus, sterilized inert gas acts as a blanket to block intruding species, sterilized water, CO2 and cleaning solution are supplied;
• (b) a computer system communicatively connected to the central distribution tank for monitoring the process variables and for modulating them to maintain growing conditions and subsequent cleaning of the growth system;
• (c) a plurality of microalgae growing tubular modules communicatively connected to the central distribution tank and positioned for exposure to a light source, wherein the microalgae growing tubular modules are fabricated of a translucent or transparent polyurethane polymer resistant to ultraviolet degradation and fabricated in continuous lengths of about 100 meters, wherein the microalgae growing tubular modules have a diameter for maintaining tensile strength, movement of a specific volume of microalgal culture and light exposure;
• (d) a pressurized pumping source connected to the central distribution tank for pressurizing the growth system, wherein the internal pressure of the growing system is at a pressure sufficient to cause a turbulent flow within the growing system and minimize the accumulation of biofilms in the microalgae growing tubular modules;
• (e) a nano-bubbler positioned between the pressurized pumping source and microalgae growing tubular modules, thereby providing and producing bubbles of CO2 for increased solubility of CO2 in the growing system;
• (f) an inline dewatering system comprising a filtration system which allows algae harvesting while the growing system is functioning, thereby maintaining algae growing concentrations in the growing system;
• (g) a temperature adjusting system communicatively connected to the jacketed central distribution tank to maintain a growth temperature in the growth system;
• (h) a venting system attached to the central distribution tank to remove unwanted gasses formed in the growth system;
• and
• (i) an inline cleaning and recovering system for capturing unused reactants and process water, and introducing a cleaning solution into the central distribution tank without disassembly and reassembly of the growth system to provide a clean growth system for reinoculating the growth system with the previous algae, introducing one or more different algae species or new waste type stream.
