Toxicity assessment of oil field produced water treated by evaporative processes to produce water to irrigation

During the productive life of an oil well, a high quantity of produced water is extracted together with the oil, and it may achieve up to 99% in the end of the well's economical life. Desalination is one of mankind's earliest forms of saline water treatment, and nowadays, it is still a common process used throughout the world. A single-effect mechanical vapor compression (MVC) process was tested. ...

Test & treat - treating hydrostatic test water

A pipeline company in Iowa conducted a hydrostatic test of its pipeline, producing 39,000 barrels of fluid for treatment. The hydrostatic test water was to be discharged in accordance with a National Pollutant Discharge Elimination System (NPDES) permit. The permit required that discharge of the treated test water could not exceed a period of 14 days from the date the test was conducted. Fluid ...

Treating Industrial Water with Membrane Technology

A variety of industries are finding that it makes sense to reevaluate the way they treat industrial process water, both to improve the quality of their products and increase the efficiency of their processes. Purification systems utilizing crossflow membrane filtration, such as reverse osmosis (RO), nanofiltration (NF) or ultrafiltration (UF) can be a good alternative to traditional filtration ...

A pilot study of a subsurface-flow constructed wetland treating membrane concentrate produced from reclaimed water

A pilot study was conducted for 7 months for the City of Oxnard, California, on the use of constructed wetlands to treat concentrate produced by microfiltration and reverse osmosis (RO) of reclaimed wastewater. The treatment performance of a transportable subsurface-flow wetland was investigated by monitoring various forms of nitrogen, orthophosphate, oxygen demand, organic carbon, and selenium. ...

In vivo genotoxicity of treated water containing the cylindrospermopsin-producer Cylindrospermopsis raciborskii

Cylindrospermopsin (CYN) is an alkaloid commonly produced by some cyanobacteria that has been implicated in outbreaks of human illness. The aim of this study was to investigate the genotoxicity of Cylindrospermopsis raciborskii cellular content (including CYN) and its byproducts resulting from chlorination during water treatment. DNA damage in blood and liver cells was analysed by the comet ...

RO Feedwater: Treat It Right

Summary Crossflow membrane filtration systems, such as reverse osmosis (RO), nanofiltration (NF) or ultrafiltration (UF), are good alternatives to traditional filtration and chemical treatment. However, to get the best performance from them, careful attention must be paid to feedwater conditions. Pretreating feedwater can lengthen the life of membrane elements, improve the quality of the ...

Minnesota makeover - treating hydrostatic test water

A pipeline company in Minnesota conducted a hydrostatic test of its pipeline, producing approximately 320,000 barrels of fluid for treatment. Fluid was pumped from the pipeline into three storage tanks located at the pipeline’s tank farm. Fluid was then pumped from the storage tanks directly to CETCO Oilfield Services onsite equipment. On average, CETCO Oilfield Services treated the fluid at a ...
