  • Patent number: 9944961
    Abstract: A process for removing sulphide from an aqueous solution comprising sulphide is disclosed, in which the aqueous solution is subjected to sulphide-oxidizing bacteria in the presence of oxygen in a reactor to oxidize sulphide to elemental sulphur. According to the process, a molecular-oxygen containing gas is supplied to a reactor containing the sulphide-oxidizing bacteria in an aqueous medium, such that one or more aerated zones and one or more non-aerated zones are created in the aqueous medium with upward liquid flow in the aerated zones and downward liquid flow in the non-aerated zones; and a feed stream of the aqueous solution comprising sulphide is injected into the reactor in the one or more non-aerated zones, wherein the one or more aerated zone(s) are not separated from the one or more non-aerated zone(s) by means of vertically extending reactor internal.

  • Patent number: 6841072
    Abstract: Method and apparatus for the anaerobic purification of slurry which contains organic constituents. Slurry which is to be treated is fed periodically or continuously to a mixture-filled, substantially closed reactor (2), while the slurry is forcibly mixed with mixture (3) from the reactor. The mixture in the reactor is subjected to upward flow through it and to a hydrolysis process. The mixture is subjected to floatation by injection of a low-oxygen gas, such as biogas which originates from the reactor, and the floating layer of solids which is formed in the process is returned to the mixture in the reactor, while the low-particle liquid which is formed in the process is discharged as effluent.

  • Patent number: 6758886
    Abstract: A three-phase separator for separating off from a fluid gas and particles contained therein, includes at least one pair of two gas collection caps extending in a horizontal longitudinal direction (L) and each having a plate section. The plate sections converge in the downward direction. At the bottom ends the plate sections leave an inlet passage, elongated in the longitudinal direction, for the fluid containing particles and an outlet passage, elongated in the longitudinal direction, for settled particles. A discharge opening for fluid, opening into the settling chamber, is provided at a level higher than the inlet and outlet passages. The inlet passage and the outlet passage are located in the extension of one another, viewed in the longitudinal direction.

  • Patent number: 6063273
    Abstract: For the biological purification of waste water, use is made of a column containing a UASB reactor (1) at the bottom and an aerobic reactor (2) at the top. The two reactors (1; 2) are separated from one another by a partition (12) in which openings are provided to allow the anaerobic effluent through into the aerobic reactor. The partition (12) is situated at some distance above the gas collection means (8) in order to form a buffer zone (13) for anaerobic sludge which has flowed through. Preferably, a floatation apparatus (3) is mounted on the aerobic reactor in order to separate biomass from the purified water.

  • Patent number: 5904850
    Abstract: A settling device (2) for a fluid containing liquid, gas and particulate material comprises liquid-discharge elements (15) fitted close to the water level of the fluid and supply elements for supplying the fluid at the bottom of the settling chamber. In the settling chamber one or more caps (12) are disposed with their longitudinal axis at an angle to the water level, such that fluid supplied at the bottom of the settling chamber flows obliquely up, forced along the bottom of the at least one cap. Whilst gas bubbles contained therein collect in the ridge (17) of the at least one cap. The gas collected in the ridge of the at least one cap is trapped by elements (18) beneath the water level of the fluid. Preferably, use is made of a row containing a multiplicity of caps (12) which are disposed in oblique, overlapping and parallel arrangement. The caps (12) can be fitted at an angle of 60.degree. relative to the water level and preferably have a mutual interval of about 6 cm.
