Microalgae photo-bioreactor using sun and LED light source for stimulation and tuning in wastewater engineering
Summary:
A Greek SME dealing with LED lighting products and installations has developed a photobioreactor for the acceleration of the reaction/growth rate of activated sludge, multiplying the standard efficiency of common devices. The company is looking for joint venture, license or manufacturing agreement, as well as research or technical cooperation agreement.
Description:
A Greek SME dealing with LED lighting products and installations has developed a bio photoreactor for the acceleration of the reaction/growth rate of activated sludge, multiplying the standard efficiency of common devices. Photobioreactors make use of light to cultivate microorganisms (algae) producing biomass. They are used in systems for sustainable energy production and wastewater treatment.

In activated sludge reactors, a mixture of microorganisms are used to convert soluble organic and inorganic pollutants into energy and insoluble bio mass, which can easily be separated. The mixture of those microorganism, in the reactors, is like a "black" box. Until now, after the installation of the system, only few things can be done to change the balance of the microorganisms. The demand of microorganisms for oxygen is covered by the aerization of the wastewater reactor.

The photobioreactor developed by the Greek SME is an innovative device which uses artificial (LED) or sun light and temperature so as to stimulate the microalgae production in wastewater engineering and increase the total procedure output. It can optimize the selection of microorganisms in the reactor by regulating temperature and light.

The use of LED light has shown a significant impact in nitrification - denitrification process in the content of bioreactors, as it increases nitrogen removal and low content of nitrates in the sewage. The heat from the sun can increase the temperature of the reactors content: an increase of 10o C in temperature, can double the reactors kinetics. The increase of the microalgae in the culture, produces oxygen as a byproduct, which is ready to be use and in a large diffused - effective ratio by other aerobic microorganisms.

The design of the reactor is focused on simplicity, energy saving and has corrosive resistance chararacteristics. An extra advantage is that it can be added in an already existing reactor optimizing the output of the existing facilities without the need of: a) additional space, b) big constructions projects or new tanks, c) dead functional time of the facilities or long lasting, start up problems.

The device can be delivered in a ready for installation form.

Current and Potential Domain of Application:
Optimize microorganisms´ cultuvation for maximum efficiency in wastewater plants. Especially in "special" applications such as treatment of wastewaters deriving from biogas production facilities, where the nitrification - denitrification is the decisive area of treatment.

The company is interested in joint venture, license or manufacturing agreement. It is also interested in research or technical cooperation agreement. Multiple cooperation schemes are sought depending the types of partner and partnership (details on relevant field below).
Advantages and Innovations:
The innovative element of the device is that it uses light and temperature as two seperate parameters for the tuning of the microorganism cultuvation for optimized function in wastewater facilities.
It uses both sun light and LED light for microalgae. In this way, the total energy demand of the device is minimum and its design gives flexibility in use.
It uses sun light heat to increase wastewaters´ temperature. That is the second parameter, which increases the overall yield in parallel wiht the use of light.
Energy saving function with the potentiality to regulate the conditions of light, heat and time in order to tune the process.
Simple, with minimum moving parts.
Corrosive resistant structure.
It can increase the capacity of the facilities without the need of large additional space, without big construction projects, without dead time in the operation of the plant. In a compact device set ready for installation.
It can probably handle special wastewater, like those that derives from biogas production tanks with manure digestion.
