  • Falling Oil Price Forces Operators to Find Cost Savings in Water Management

    When oil prices were 80 to 100 dollars per barrel, water management costs were high, but they were tolerable when money was flowing profitably. However, as today’s falling price nears 40 dollars, water related costs are still high and only exacerbate widespread industry losses. The 150 US-based companies tracked by Oil & Gas Journal and Oil & Gas Financial Journal reported that ...

  • Taming taste and odor (T & O) problems in a water treatment plant

    Taming Taste & Odor (T&O) Problems Some taste and odors are caused by mineral constituents in the water, e.g. excess chlorine and hydrogen sulfide. However the majority of taste and odor are the result of biologic activity. Spring turnover of lakes and algal blooms are responsible for Blue-green algae (Cyanobacterium), Green algae and diatoms that introduce filter clogging organisms ...

  • TB 72: Chinese chemical plant optimizes water treatment by replacing double pass ro with a single pass ro and liqui-cel® contactor system

    Electrodeionization (EDI) is widely used in many industrial water treatment systems throughout the world. In order to maximize the operating stability and life expectancy of an EDI system they were often designed with double pass RO using caustic injection pretreatment. However, in response to recent efforts to lower the capital expenditure and operating costs of double pass RO water treatment ...

  • Effect of Preparation Technique on Permeability and Strength of Cement-Grouted Sand

    The effectiveness of cement grouting is generally evaluated in terms of the improvement attained in the engineering properties of the grouted soil. Although this degree of improvement should logically be related to the amount of cementitious particles present in the pore spaces of the grouted sand, and indeed is to some extent, the method of preparing the specimens can exert an even stronger ...

  • UV disinfection for enhanced oil recovery and other oilfield applications

    One of the biggest challenges facing oil companies today is how to extract more oil from the discoveries made in the last 40 years. Estimates vary, but approximately 66% of the discovered oil gets left in the ground. The International Energy Agency has estimated that if, in the next 20 years, this figure could be reduced to 50%, then this would increase the world's recoverable oil by 1.2 trillion ...
