Cooling water systems are commonly used to cool a process, either steam, gas or liquid, through heat exchangers or condensers in various plants. The heat exchangers or condensers can be corroded easily or have scale and biofilm growth due to the poor water treatment program. The corrosion, scale, and biofilm growth on heat exchangers can lead to significant reduction in heat exchanger efficiency and lifetime. The repair expense or loss of production often costs plants a few hundred thousand or millions of dollars per day for heavy industries, such as chemical and power plants, refineries, and steel mills. Thus, cooling water treatment is critical to maintain the integrity and efficiency of heat exchangers.

In open cooling water systems, phosphorus-based (P-based) programs are the most widely used treatment program for corrosion and scale control. Excellent performance of P-based programs has been long proved in many institutional and industrial applications. Despite this high performance, phosphorus is one of the limiting nutrients to bacteria and may accelerate microbial growth if with excess concentration. A recently developed and innovative non-phosphorus(non-P) program has been deployed globally, not only to comply with discharge regulations, but also to provide additional benefits/value to our customers. One feature of the non-P program is to eliminate/reduce phosphorous feed that enhances biological control. First case study of a non-P program is in a microelectronics plant. The new non-P program showed excellent corrosion, scale, and microbiol control performance. Superior performance of corrosion and scale control was demonstrated and is fully understood from a mechanistic perspective. For microbiol control, the bacteria count dropped two orders of magnitude after switching from an incumbent phosphorus-based program to the innovative non-P program. In the 2nd case study, an ethanol production plant recently switched from P-based program to the non-P program to improve the algae control in the discharge pond. After 10+ years suffering from algal bloom at summertime, very positive results have been observed. Moreover, corrosion control was further improved as reported.

This study describes an effort to find a method to control bacteria in 130 remote freshwater fiber glass storge tanks with an effective low-cost, convenient treatment method. Freshwater, in this application, is being used to control halite scale formed in the production from unconventional oil wells in the Williston, North Dakota, USA area. The water is sourced from local freshwater rivers and trucked to location and stored in 400 barrel (bbl) freshwater tanks. The water stored in the tanks is injected continuously, and the tanks are refilled on a variable schedule.

In Oil Sands In-Situ operation bitumen is often extracted from underground oil sands deposits through SAGD (Steam Assisted Gravity Drainage) technology. This method involves forcing steam into sub-surface oil sands deposits, usually those at depth greater than 150m (492 ft), to heat the bitumen locked in the sand, allowing it to flow well enough to be extracted [1]. This process technology makes it possible to access the underground deposits otherwise difficult to access through the open mine method. It is particularly relevant in Canada because it is the most common method of in situ extraction used in the oil sands.
