Oil Analysis Helps Water Plant Cut Annual Maintenance - Case study
The city of Chandler (Ariz.) Municipal Utilities Department (MUD) employs coagulation, sedimentation, active flow control and filtration to produce 60 million gal per day (mgd) of water at its surface water treatment plant. In addition, the system includes 27 wells and 21 booster stations controlled by SCADA. Water distribution is provided through more than 1,200 miles of water main, in excess of 7,500 fire hydrants and more than 25,500 water valves. The city also has several facilities that treat wastewater, and...
Validation of Salt Water Disposal Well Treatment Plants with Handheld Oil in Water Sample Analyzer
Salt Water Disposal (SWD) well operators often dispose a substantial volume of oil inadvertently when injecting salt water, thereby losing the opportunity to sell the oil on the market and potentially reducing the ability to inject water in the well. Injection facilities are typically operated with minimal instrumentation or system optimization, which means the operators don`t know how much, or when, oil is being disposed. A typical oil field tank battery for oil/water treatment consists of a collection tank, a...
Reservoir Management - Online Oil-In-Water Monitor - Case Study
Background Older generation online oil-in-water (OiW) monitors may suffer from fouling of optics due to scales, soaps, emulsions, sludge, etc., resulting in inaccurate (usually low) concentrations. New generation OiW monitors: Yield more accurate O iW concentrations Improve accuracy of the OiW measurements, allowing operators to optimize water treatment systems so that more product is recovered and less is re-injected or discharged into the environment. Reduce operator maintenance and recalibration...
Anti-fouling graphene oxide based nanocomposites membrane for oil-water emulsion separation
Anti-fouling copper hydroxide nanowires (CHNs)-graphene oxide (GO) nanocomposites membrane was fabricated by a vacuum-assisted filtration self-assembly process. CHNs were covered on the surface and inserted into the interlayers of the GO nanosheets to form the rough surface and nanostructure channels. The membrane with water contact angles (CAs) of 53° and oil CAs of 155° exhibited superior stability, hydrophilicity, underwater superoleophobicity and ultralow oil adhesion, and hence it could separate the oil-water...
Oil and grease in waste water
Determination of oil and grease in waste water according to Standard Methods AWWA 5520 This Application Note describes the extraction and determination of oil and grease from waste water samples following Standard Methods 5520 part D (Soxhlet Extraction Method). “Oil and grease” is defined as any material recovered as a substance soluble in the solvent. Therefore, compounds with similar physical properties will be determined as well as oil and grease (e.g.sulfur compounds, organic dyes, chlorophyll)....
