Patent number: 7722768Abstract: The invention is directed to a process for the simultaneous removal of BOD and phosphate from a liquid containing ammonium, BOD, phosphate and magnesium, the method comprising: feeding the liquid to a reactor containing BOD-oxidising biomass; ensuring that the liquid in the reactor contains an excess to stoichiometry of ammonium and magnesium relative to phosphate, wherein the stoichiometry is related to the stoichiometry of struvite; oxidising at least part of the BOD; adjusting the pH of the liquid in the reactor at a desired value; forming solid material in the reactor, the solid material comprising struvite; separating at least part of the solid material from the reactor effluent; returning a part of the solid material to the reactor. The invention is also directed to a reactor for this process. The advantage of the process and the apparatus is that in one reactor both BOD and phosphate are removed from the liquid.Type: GrantFiled: September 9, 2005Date of Patent: May 25, 2010Assignee: Paques B.V.Inventors: Wiebe Ruurd Abma, Sjoerd Hubertus Josef Vellinga, Ronald Mulder

Patent number: 6841072Abstract: 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.Type: GrantFiled: March 26, 2003Date of Patent: January 11, 2005Assignee: Paques Bio Systems B.V.Inventors: Sjoerd Hubertus Jozef Vellinga, Ronald Mulder

Patent number: 5518618Abstract: A system for purifying nitrogenous waste water by biological nitrification and denitrification, comprises at least two essentially separated reactor chambers, a liquid supply (4) and a liquid discharge (5). The first, aerated reactor chamber (1) is provided at the top with an overflow to the second, oxygen-depleted reactor chamber (2). The oxygen-depleted reactor chamber (2) is divided at the top into a degassing chamber (7) and a settling chamber (8) having an overflow (9) to the liquid discharge. The first reactor chamber is provided with an air supply (11, 18) and an air discharge (12) located above the supply. The first reactor chamber may be partly divided into a riser (14) and a downcomer (15) which allow, as a result of the air supply, mass circulation to take place in the aerated reactor chamber.Type: GrantFiled: December 12, 1994Date of Patent: May 21, 1996Assignee: Paques B.V.Inventors: Ronald Mulder, Sjoerd H.
