A wastewater treatment method and process returns the whole excess sludge mixes it with the influent wastewater. The mixed flow is introduced in distributed in the bottom of a treatment tank. High turbulence aeration is done in the middle or upper parts of the treatment tank. Anoxic, anaerobic, facultative and aerobic zones are formed while the mixed flow is travelling from bottom of the treatment tank to the top. Due to futile cycle around the aeration and facultative zone right beneath the aeration the excess biological sludge production is eliminated. This process also can remove odor and can denitrify nitrate. There is a new type of packing media with high specific surface area without clogging that has been introduced and described in this invention. The present invention can be used for different application including domestic or industrial wastewater treatment, large or small. The described packing media can be used in different wastewater treatment plants or in aquaculture and cooling, contact or stripping towers. |
