Outdoor apparatus and methods to treat wastes, wastewater and contaminated water bodies
View Patent ↗The technology relates to an apparatus, methods and applications to grow microorganisms on-site to treat contaminated environments. The apparatus is designed to function under a wide range of environmental conditions including extreme cold, extreme heat and direct exposure to sunlight. Such environments normally reduce the shelf-life of the organisms in the storage chamber that feeds the fermenter where they are being grown. These environments can also lower the growth rate of the organisms in the fermenter causing diminished cell output. Quite often the optimum point of application for the organisms is outdoor and too far from structures with appropriate protection from ultraviolet radiation from the sun or from excessive cold or hot weather. The technology in the application addresses these issues.
1. An outdoor apparatus for growing and delivering biosafety-level-one bacterial, fungal or actinomyces cultures to wastewater comprising:
a coated double-wall storage chamber for containing microorganisms, said coating for protection against heat and ultraviolent radiation;
a coated fermentation chamber, said coating for protection against heat and ultraviolent radiation;
a delivery system to provide nutrients and microorganisms from said storage chamber to said fermentation chamber including a low shear pump or an auger for delivery of microorganisms and nutrients or nutrients;
an optional canopy for covering the apparatus from weather conditions;
an air pump to provide oxygen and aeration to said fermentation chamber;
a heater for maintaining the temperature of said fermentation chamber;
a bacterial air fabric filter and flexible microporous hose air diffuser disposed within said fermentation chamber to provide aeration and agitation;
an optional air conditioner for cooling said apparatus;
a programmable controller for controlling the delivery nutrients and microorganisms selected based on the wastes being treated;
a low shear pump in operative connection with a solenoid vale or actuator valve for delivering and dosing fermentation broth from said fermentation chamber to said wastewater; and
a water supply system to provide water to said fermentation chamber and for rinsing and cleaning said fermentation chamber.
2. The outdoor apparatus for growing a delivering biosafety-level-one bacterial, fungal or actinomyces cultures to wastewater as in claim 1 , wherein said nutrients are bioremediation inorganic or organic compounds.
3. The outdoor apparatus for growing a delivering biosafety-level-one bacterial, fungal or actinomyces cultures to wastewater as in claim 2 , wherein said bioremediation inorganic nutrients are selected from the group consisting of potassium phosphates, sodium phosphates, ammonium phosphates, ammonium chloride, ammonium sulfate, magnesium chloride, magnesium sulfate, ferrous sulfate and ferric chloride.
4. The outdoor apparatus for growing a delivering biosafety-level-one bacterial, fungal or actinomyces cultures to wastewater as in claim 2 , wherein said bioremediation organic nutrients are selected from the group consisting of proteins, carbohydrates, gelatin, casein, yeast extract, beef extract, molasses, sucrose, dextrose and mixtures thereof.
5. The outdoor apparatus for growing a delivering biosafety-level-one bacterial, fungal or actinomyces cultures to wastewater as in claim 1 , wherein said microorganism delivered to said fermentation chamber is selected from the group consisting of bacteria, fungi, actinomyces and biosafety-level one microbes.
6. The outdoor apparatus for growing and delivering biosafety-level-one bacterial, fungal or actinomyces cultures to wastewater as in claim 1 , wherein said programmable controller controls delivery of nutrients, microorganisms, temperature, oxygen to said fermentation chamber with the organisms selected based on the wastewater conditions.
7. The outdoor apparatus for growing a delivering biosafety-level-one bacterial, fungal or actinomyces cultures to wastewater as in claim 1 , wherein said microorganisms delivered to said fermentation chamber in a concentration range from 10 6 to 10 10 cfu/ml.
