Injection / Cooling Water Systems

“Your ‘long term cost of ownership approach’ is what won the order… “

Over the years Royal Dahlman strengthened its market position in water filtration. Starting in the early 90’s with its first seawater injection filter package the technology applied has been developed to a sophisticated high end solution. Whilst sand filters, sometimes called deep bed filters or multimedia filters, are a very common and old technology, Royal Dahlman has improved the package design system integrity allowing designs for a lower long term cost of ownership providing you with the benefits of:

  • Proven technology
  • Custom made and modular design
  • Smallest Plot space
  • Optimal backwashing with long life of sand bed
  • Trouble free maintenance
  • Low operating costs
  • Performance software modelling

Injection Water Filtration

Water injection or water flooding refers to the method in the oil industry where water is injected into the reservoir, usually to increase pressure and thereby stimulate production. Water injection wells can be found both on- and offshore, to increase oil recovery from the existing reservoir. Produced water is often used as an injection fluid. This reduces the potential of causing formation damage due to incompatible fluids, although the risk of scaling or corrosion in injection flow lines or tubing remains. While the filtration method is similar to that of cooling water filtration, the application and duty spec are more stringent. In other words, these filtration systems needed to filter out particles from injection water must remove solids to an even lower micron rating. 

Cooling Water Filtration

Today Royal Dahlman is a strong player in the field for side stream cooling water filtration. Especially in areas where a high air born dust load is present, such as desert area’s (sand storms) and heavy industrial areas. In these severe circumstances the system design must deal with these extraordinary conditions. Royal Dahlman's design is preferred by major oil & gas and petrochemical companies based on the proven track records. The Royal Dahlman system design is also available for the majority of cooling water system designs.
