Abstract: The present invention relates to a biological filter for the purification of waste gases comprising a bed of biologically active carrier material consisting of pith extracted from coconut husks, the bed being contained such that the waste gases are brought in contact with the said bed and removed from the bed at points spatially separated from the inlet points.

Abstract: A high-rate reactor system, (applying a high superficial velocity), capable of treating partially soluble, complex, high-strength wastewater. The reactor system is configured in multiple stages and has the ability to retain complex insoluble substrates in a wide range of particle sizes in spatially separate stages for sufficient residence time to enable complete degradation. A vertically oriented vessel has neighboring upper and lower chambers, each chamber having a gas retention space and a liquid retention space. A filter chamber has an inlet communicating with the liquid retention space of the lower chamber and an outlet communicating with the liquid retention space of the upper chamber. A gas conduit communicates the gas retention space of the lower chamber with the gas retention space of the upper chamber. A discharge device enables gas to be periodically discharged from the lower chamber to the upper chamber through the gas conduit.

Abstract: An embodiment of the present invention relates to a biological process for continues purification of waste water by converting its constituents to a solid form that can be easily separated using retainable biological catalysts and a novel reactor hereafter referred to as “Reverse Fluidized Loop Reactor” (RFLR) for performing the above said process.

Abstract: The present invention relates to a high-rate reactor, (applying a high superficial velocity), capable of treating partially soluble, complex, high-strength wastewater. This is the first single reactor system in a compact and mechanically simple package that is configured in multiple stages and has the ability to retain complex insoluble substrates in a wide range of particle sizes in spatially separate stages for sufficient residence time to enable complete degradation, thereby achieving highly efficient performance for the removal of both solid and dissolved contaminants.
