Patent number: 8066878Abstract: The invention relates to an anaerobic purification device for purification of influent. The device has a reactor tank, an inlet for introducing influent into the tank, a water collecting device for collecting purified water, a gas collecting system for collecting gas from the fluid contained in the reactor, a gas-liquid separation device, a riser for passing liquid into the separation device by gas lifting action caused by gas collected in the gas collecting system, and a downer for returning liquid and sludge from the separation device into the lower tank section. According to the invention this device is characterized in that it is arranged to define, in the downer at the level of the liquid surface, a head pressure of, at least, approximately 1.4 m water column (approximately 0.14 bar). The invention also relates to a method for anaerobic purification device for purification of influent.Type: GrantFiled: June 10, 2005Date of Patent: November 29, 2011Assignee: Paques B.V.Inventors: Sjoerd Hubertus Josef Vellinga, Jelle Hendrik de Boer, Antonius Johannes Jorna, Leonard Hubertus Alphonsus Habets

Patent number: 6063273Abstract: 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.Type: GrantFiled: May 6, 1999Date of Patent: May 16, 2000Assignee: Paques B.V.Inventors: Leonard Hubertus Alphonsus Habets, Antonius Johannes Hendrikus Hyacinthus Engelaar, Sjoerd Hubertus Jozef Vellinga

Patent number: 5972219Abstract: A process is described for the aerobic treatment of effluent in a reactor of the UASB type, into the bottom of which the effluent to be treated is fed and, at the same time, oxygen is fed in an amount such that the growth of a facultative and an aerobic biomass is promoted. An apparatus for the aerobic treatment of effluent is also described, which apparatus consists of a UASB rector, distributors for supplying liquid and aeration means being located at the bottom of the reactor and means for integrated settling of biomass and gas collection being located at the top of the reactor. The apparatus can also be an integrated anaerobic/aerobic reactor.Type: GrantFiled: July 17, 1997Date of Patent: October 26, 1999Assignee: Paques B.V.Inventors: Leonard Hubertus Alphonsus Habets, Wilhelmus Johannes Bernardus Maria Driessen
