A lightweight, bioplastic, mobile, floating oil spill mechanical/biological recovery system is dimensionally compact, and quick to assemble. The floating platform can be readily positioned within any waterborne oil/contaminant spill area. After assembly, this platform or apparatus can be directed by either a hand-held digital radio control transmitter or GPS directed mechanism. A lower, multi-roller slip-on belt is designed to be mounted over a circular base support aeration hub assembly with alternating/spaced slotted ring water drainage separators. The belt and aeration assemblies dip bioaugmentation product into the contaminant site thereby exposing microorganisms to both oxygen and target contaminant for treatment and metabolism. Various mechanisms for enhancing metabolic activity of the bioaugmentation product operate in tandem with the primary belt and aeration assemblies to promote effective contaminant metabolism and overall treatment regimes.

A bioreactor for anaerobic, aerobic and anoxic digestion of organic matter from wastewater, having a bottom anaerobic zone where the wastewater is fed where anaerobic bacteria produces biogas and the sludge produced is deposited on the bottom and subsequently extracted. An anoxic middle zone contains denitrifying bacteria which converts nitrates to nitrogen, and an aerobic zone at the upper part where at least one biological contact rotor is disposed, which degrade organic matter remaining in the water. The growth of nitrifying bacteria converts ammonia nitrogen into nitrites and nitrates. The tank has a plurality of rhomboids for biogas, sludge and scum collection that join together form a intermediate polyhedral separator panel. The rhomboids joined together define conical collectors with connecting nozzles of ducts from a capture and conduction network of biogas and funnel-shaped manifolds with connecting nozzles of ducts that define a capture and conduction network of sludge and scum.

Methods and apparatuses for adjusting an angular orientation of a media unit having an opening are disclosed. The media unit may be secured to a rotating frame. In addition, a rotating frame including multiple media units at different angular orientations is disclosed.

A rotating biological contactor (RBC) is provided that includes a media wheel with a plurality of vanes configured for growth of algae thereon. The media wheel is configured for rotation by air directed from an air diffuser to impinge on the vanes such that when said media wheel is partly immersed in water rotation of the media wheel alternately exposes algae growing on the plurality of vanes to sunlight and to the water;. A frame is connected to an axle of the media wheel. Only one of the media wheel and the frame is constructed with a buoyancy sufficient to support the media wheel partly immersed in water during rotation of the media wheel.

A process for forming a biofilm carrier suitable for use in a moving bed biofilm reactor (MBBR) is presented. A blowing agent is mixed with a plastic material to form a blended material. The blended material is then heated to a temperature where the blowing agent liberates gas by decomposition. The heated blended material is extruded through a die to provide the extrudate with a profile of the biofilm carrier. Advantageously, biofilm carriers produced in this manner have increased effectiveness when compared to conventional biofilm carriers.

A method of using algae to remove a contaminant or pollutant from a first fluid is provided. The method can include providing a growing apparatus having a first reservoir containing the first fluid and a second reservoir containing a second fluid, and growing the algae using the growing apparatus. The method can further include exposing the algae to the first fluid within the first reservoir where the algae uptakes the contaminant or pollutant from the first fluid, and exposing the algae via a belt to the second fluid in the second reservoir where the algae is stimulated to release the contaminant or pollutant. Exposing the algae to the first fluid within the first reservoir or the second fluid may change a growth rate of the algae.
