    摘要： 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.

    摘要： A filter element (1) comprising a central tubular body/core (2) and a plurality of radially outwardly directed fins (3) forming the main structure of the element, the radially outwardly directed fins (3) projecting outwardly from said central tubular body/core (2) and whose radial length increases stepwise from each end of the central body or core to a maximum length located centrally of the length of the body or core (2), thereby effectively providing a generally double back-to-back conical appearance, a stiffening ring (8) arranged to encircle with a gap therebetween the body/core (2) at a mid-region thereof and whose plane is perpendicular to the axis of the body or core (2), the central tubular body/core (2) including one or more radially inwardly directed ribs (12).

    摘要： A process for aerobic operation of fluidized bed reactors with tubular fluidized bodies provided with fins and/or channels on the inside and outside, in which process a dilute aqueous solution of stabilized folic acid is metered into the wastewater to be cleaned, and in which process oxygenous gas is supplied with a ventilation rate (VL) sufficient for aerobic microorganisms, which is defined as the ratio of the amount of air introduced into the fluidized bed reactor per hour in m
    3 /h divided by the cross-sectional area of the fluidized bed reactor in m
    2 , is characterized in that the ventilation rate (VL) is selected such that the microorganisms colonize predominantly only on the inside of the fluidized bodies.
