Modular photobioreactor for microalgal biomass production

Abstract

This invention related to photobioreactor providing a modular, scalable, and sustainable system for efficient microalgae cultivation, addressing diverse applications such as biomass production, environmental remediation, and bio-compound extraction. This system includes; a body constructed within a standard 20-foot corten steel, an airtight chamber which occupies approximately three-quarters of the body's internal volume for 10 containing the freshwater or saltwater needed for microalgae cultivation, a lightning system (3) including a plurality of LEDs which are programmable and adjustable in both intensity and duration, allowing precise management of lighting conditions to optimize microalgal growth, which is installed on the body ceilin an aeration and mixing system that providing CO2 for photosynthesis from air by a compressor (1) and 15 mixing the biomass within the chamber, a feeding system (4) ensuring a continuous and controlled supply of essential nutrients to the microalgal culture, a photocatalytic filter (2) purifying contaminants in air before being injected into the reactor, a control unit (5) that monitors and manages all key operating parameters of the photobioreactor in real- time, such as pH, temperature, CO₂, and nutrient concentration, photovoltaic panels 20 providing electrical energy for reactor, which is mounted outside of body and a filter (8) that filters contaminants in the water which is sent by a pump.
