摘要： The present invention concerns a method of reducing fouling of ceramic membranes by adding an effective amount of a tannin polymer to SAGD process water. Additionally, a cationic and/or an anionic flocculant can also be added to treat the process water. Once the process water is treated, the solids are then separated out and the resulting clean process water is then passed through a ceramic membrane. Typically, the tannin polymer used in treating the process water is comprised of a Mannich reaction product of an amine, an aldehyde, and a tannin. The components are reacted at an acidic pH wherein the molar ratio of amine to tannin present is from about 1.5:1-3.0:1. Exemplary tannin/amine/formaldehyde compounds include tannin/melamine/formaldehyde polymers, and tannin/monoethanolamine/formaldehyde polymers.

摘要： In a process and apparatus for treating produced water, for example for re-use in an oil or bitumen extraction operation of for treating frac water, the produced water flows through a series of treatment units. A portion of the produced water may by-pass one or more of the treatment units but the by-pass portion may be such that the treated water is still acceptable, for example for discharge or reuse. Concentrations of oil and grease, organic carbon, silica, pH or related parameters in the produced water may be monitored and used to control the process or apparatus. Control of the process may involve one or more of altering a by-pass portion, altering the addition of chemicals, and altering the operation of a unit process. The process may be controlled to respond to upset conditions, or such that the concentration of one or more limiting contaminants is near, but not over, a specified maximum for re-use or discharge.
