20090211954 | Apparatus For Denitrifying Wastewater - Disclosed is an apparatus for denitrifying a solution that includes a denitrification tank configured to receive a portion of the solution for a period of time. Controlling an amount, duration and frequency of introduction of polyethylene glycol into the solution promotes indigenous heterotrophic bacteria depleting dissolved oxygen in the solution and obtaining oxygen from nitrate in the solution. | 08-27-2009 |
20090211957 | Apparatus For Denitrifying Wastewater - Disclosed is an apparatus for denitrifying a solution that includes a denitrification tank configured to receive a portion of the solution for a period of time. Controlling an amount, duration and frequency of introduction of polyethylene glycol into the solution promotes indigenous heterotrophic bacteria depleting dissolved oxygen in the solution and obtaining oxygen from nitrate in the solution. | 08-27-2009 |
20090236283 | Method of Denitrifying Wastewater - Disclosed is a method of denitrifying a solution including introducing into the solution an amount of a carbon source within a duration and at a frequency so that indigenous heterotrophic bacteria deplete dissolved oxygen in the solution and obtain oxygen from nitrate in the solution. Related apparatuses and compounds also are disclosed. | 09-24-2009 |
20100163484 | Compound for denitrifying wastewater - Disclosed is a method of denitrifying a solution including introducing into the solution an amount of a carbon source within a duration and at a frequency so that indigenous heterotrophic bacteria deplete dissolved oxygen in the solution and decompose oxygen from nitrate in the solution to obtain its combined oxygen. Related apparatuses and compounds also are disclosed. | 07-01-2010 |
