Comparing Oil in Water Analysis Methods
Wilks Enterprise has published a new White Paper that discusses various oil in water methods and their correlation with regulatory methods. While the amount of oil in water is highly regulated -- it can also be a challenging measurement. It is complicated by the fact that oil comes in many forms and the measurement is defined by the particular regulatory method. When EPA 1664 is the regulatory ...

Techniques for Oil in Water Analysis
The people responsible for conducting oil in water measurements understand that the measurement can be quite challenging. Wastewater from different sources can contain many different types of hydrocarbons, each with different chemical make-ups. On top of the lack of chemical uniformity in different oils, there has been a large variety of methods developed to quantify the oil in the wastewater. ...

Solvent-free oil-in-water analysis
Non-ionic surfactants can homogenize oily, produced water samples, creating optically clear microemulsions that are ideal for fluorescence measurements [1]. The use of surfactants to reduce fouling and improve the performance of on-line, fluorescence-based, oil-in-water monitors has been reported previously [2,3]. This paper describes the use of surfactants to prepare discrete water samples ...

Oil-In-Water Analysis. Verification of Particle Counter results by optical microscopy
For my research work, which concerns separation of liquid/liquid dispersions, I selected the Spectrex PC2200. It covers the whole range of droplet sizes which are of interest, i.e. from 0.5 to 100 microns. The procedure for analysis is very simple and results are obtained in less than a minute. This makes the Spectrex instrument very handy for use in the lab as well as for field measurements (A ...

Will your oil in water analysis method match the regulatory method?
Anyone involved in field analysis of oil in water will continually get the question “Does your equipment match the regulatory method?” While the amount of oil in water is highly regulated -- it can also be a challenging measurement. It is complicated by the fact that oil comes in many forms and the measurement is defined by the particular regulatory method. When EPA 1664 is the ...

Oil in Water Analysis Method Match Regulatory Method - Case study
The analysis of oil in water is a worldwide problem that crosses many industries, analytical methods and regulatory agencies. For those in the petroleum industry, the offshore platform oil and grease limits for produced water can be quite different from the effluent coming out of the refinery. For the expanding hydraulic fracturing industry, oil in water limits are driven by whether the frac or ...

Understanding Oil-in-Water Instrument Specifications
The measurement capabilities of oil-in-water analysis methods are described by several analytical figures-of-merit. Examples are: Range (Linear and Dynamic) Limit of Detection (LOD) Limit of Quantification (LOQ) Precision (Repeatability and Reproducibility) Sensitivity Accuracy Response Time Some or all of these are often specified by customers in the bid packages issued when selecting a ...

What the Wastewater Industry can learn from the Petroleum Industry when it comes to measuring oil in water
I recently read a comment in the Steve Jobs biography by Walter Isaacson that different divisions within a company do just what the name implies—divide a business. Integration across and communication between the departments was essential to smooth functioning product. I think the same is true in the analytical analysis/measurement world—there seems to be a divide in communication ...

Portable IR Analyzers Provide Petroleum & Wastewater Industries with Accurate Oil Content Measurements
Fixed filter infrared (IR) analyzers have been used to test oil levels in produced water on off-shore and on-shore drilling platforms for well over 45 years. U.S. EPA methods 418.1 and 413.2 were used extensively on a worldwide basis until the Montreal Protocol called for Freon (the solvent used in the analysis) to be phased out. Infrared analysis using tetrachloroethylene (perchloroethylene) is ...

Comply with Highly Regulated Oil in Water Measurements Using Portable Infrared Analyzers
The Petroleum Industry – both offshore and onshore -- has regulations that limit the amount of oil in discharged water. Fixed filter infrared (IR) analyzers have been used to test oil levels in produced water on drilling platforms for over 45 years for a number of reasons. On oil rigs where real estate is at a premium, infrared analyzers such as the Wilks InfraCal TOG/TPH Analyzers are ...

Factors Affecting Oil in Water Testing Methods
Various factors need to be considered when comparing methods to measure oil and grease in water. Whether you are trying to meet effluent limits for an NPDES (National Pollutant Discharge Elimination System) permit, comply with oil and grease limits for the Clean Water Act (CWA), or an industry satisfying a POTW’s (Publically Owned Treatment Works) discharge permit, it is important to ...

Matching oil in water analyses with regulatory methods
While the amount of oil in water is highly regulated, it can also be a challenging measurement. It is complicated by the fact that oil conies in many forms and the measurement is defined by the particular regulatory method. When EPA 1664 is the regulatory method, the "oil" is anything that is extracted into hexane and remains after the hcxanc has been evaporated and appears as weight. In regions ...

Emulsion-Breaking Techniques for Accurate Oil in Water Measurements
A White Paper discusses emulsion-breaking techniques for ensuring accurate oil in water measurements. Certain water samples, such as those containing detergent, may form an emulsion when oil in water extraction into a solvent is done. In order to ensure an accurate measurement, the emulsion must be broken. Six techniques are described that can be used for reducing an emulsion in order to obtain ...

Matching Oil in Water Analyses with Regulatory Methods - Case study
When analyzing oil and grease in water while out in the field, it is important to use an EPA approved method and equipment. While the amount of oil in water is highly regulated, it can also be a challenging measurement. It is complicated by the fact that oil conies in many forms and the measurement is defined by the particular regulatory method. When EPA 1664 is the regulatory method, the "oil" ...

New oil spill response application note from China
The Problem: Oil may spill out in the process of oil exploration & development, refining, storage and transportation and enter into open water environment like oceanic environment due to incident or incorrect operation. Oil spill damages include to human heath, safety, ecological environment, aquaculture. In China, the State Oceanic Administration requires the oil content in the discharge to ...

Oil Analysis Helps Water Plant Cut Annual Maintenance costs by $25,000 - 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 ...

Monitoring Hydrocarbons in Wastewater - Case Study
The Situation A wastewater treatment company operated an oil/water separation facility on a multi-acre industrial site in Northern California. Its purpose was to recycle oil products for profit while at the same time providing a wastewater treatment service for industries based in Northern California. The oily water mixes processed by the company were obtained from tanker bilges, contaminated ...

How has GWT RO Waste Water Recycling Helped Industrial Organizations Reduce Costs & Reuse Their Wastewater?
Reverse osmosis desalination isn’t just useful for drinking water or process water TDS removal. RO waste water recycling can make use of the reverse osmosis process in a tertiary stage treatment to greatly reduce total dissolved solids and increase the quality of the treated water. Post treated water can typically be reused in many industrial process water applications. Many companies seek ...

Different technology options for monitoring oil in produced water – inline continuous monitoring and IR analysis
No offshore facility wants to be caught with a sheen around their platform as that can result in a costly fine for exceeding discharge permit limits for oil. Onboard oil in water analyzers are necessary to ensure the oil/water separation systems are functioning properly before overboard disposal of the produced water. Bench top analyzers have traditionally been used to test oil in water although ...
