摘要： A system for treating produced water, for example from a SAGD bitumen production operation, has a treatment unit using chemical oxidation (CO) or electromagnetic treatment (ET) to destroy or degrade organics in the produced water. The treatment module may use CO or ET in combination with biological treatment or sorption processes or both. When the treatment module is used upstream of a steam generator, it reduces fouling in the steam generator and in any blowdown water treatment device. A brine concentrator or a crystallizer may be used to treat the blowdown water. The treatment module may be used in combination with a nanofiltration (NF) or reverse osmosis (RO) membrane filter. Optionally, the produced water may be treated with an ET process such as microwaves directly upstream of a steam generator or upstream of a concentrator or crystallizer in a blowdown water stream.

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.

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： A process to reduce or prevent biofouling, by destroying or deactivating microbiological content of feedwater, or other liquid, prior to its entrance into membranes or process equipment, such as heat transfer equipment. The process comprises the use of electrical discharge and/or electric fields to destroy microbes that result in the biofouling of surfaces. By destroying the microbiological content of the water the microbiology no longer is able to create a restricting biofilm upon or within said process equipment.
