Industrial gas streams such as flue gas streams are treated for nitrogen oxides and other contaminants in dry or semi-dry scrubbers. After the flue gas stream has been contacted with a sorbent, ozone is mixed downstream into the flue gas stream thereby oxidizing the nitrogen oxides and other contaminants.

A method for removing contaminants from the combustion gases generated by the incineration of waste. Air is injected into an incineration device along with a fuel and is supplemented by a oxygen feed. The resulting combustion waste gas stream contains contaminants such as nitrogen oxides and is quenched, then fed to a reaction zone where it will contact ozone for a predetermined period of time. The thus treated combustion waste gas stream can be fed to a scrubber assembly where the reaction products formed by the reaction of ozone and the contaminants are removed.
A method for removing contaminants from a gas stream by feeding the gas stream into a scrubber that can use seawater as the scrubbing medium. The gas stream is first scrubbed with the seawater and then mixed with ozone to remove the contaminants. Nitrogen oxides that are present in the gas stream are converted to nitric acid/nitrates and these are recovered via condensate or coalesced mist for neutralization. The treated gas stream is then treated by a second scrubber whereby other contaminants such as sulfur oxides, particulates and the like are removed and the thus treated gas stream is exhausted to the atmosphere. Optionally a droplet separator may be present in the scrubber.
An exhaust gas stream from a combustion process is conveyed through a gas distributor at an inlet of a wet horizontal spray scrubber where it is partitioned into a plurality of spaced apart gas streams. The gas stream is partitioned in the scrubber without the need for any physical partitions. A preselected number of the partitioned gas streams are mixed with ozone to oxidize the contaminants. The oxidized gas streams are then sprayed with an aqueous medium to capture the oxidized contaminants and remove them from the treated gas streams. The treated gas streams are then recombined with the untreated gas streams. Excess ozone present in the treated gas streams is consumed by oxidation of contaminants in the untreated gas streams before the combined gas stream is released to the atmosphere.

Aqueous liquid having an oxygen demand flows into a treatment vessel where it is treated by suspended aerobic bacterial solids in the presence of dissolved oxygen. A pressurised flow of the treated liquid passes to a clarifying membrane separator effective to separate the flow into a discharge stream of clear liquid and a pressurised recycle stream concentrated in the aerobic bacterial solids.
